SAAB 90005 AND 9000 CD FOR 1990
Brain over Brawn: Saab’s Balanced Engineering Approach
`ORANGE, Conn. — 5aab’s long established tradition as an engineering innovator continues with the 1990 90005 and 9000 CD, which are now equipped with the new 2.3 liter naturally- aspirated engine. Like all other 5aab’s, both the 90005 5-Door Hatchback and the 9000 CD 4-Door Sedan include a driver’s side
air bag and anti-lock brakes (ABS) as standard equipment to supplement each car’s high level of occupant protection. In addition, Saab’s patented Direct Ignition system debuts in both aturally-aspirated models —— previously, the system was reserved for turbocharged 9000 variants only.
Since cars are not judged on the individual merits of performance, practicality, roadholding or safety alone, Saab has continued to dedicate its design expertise to balance these demands through engineering innovation. The 9000S enjoys improved acceleration and overtaking performance from 5aab’s new 2.3 liter naturally-aspirated engine, which is a state-of—the—art four cylinder with counter- rotating balance shafts, four valves per cylinder, Direct
Ignition, and twin overhead camshafts. The engine offers increased torque and horsepower over its 2.0 liter predecessor and is rated at 156 ft.-lb. (212 Nm) torque at 3,800 rpm and 150 hp (110 kw) at 5,500 rpm — the highest ever offered in a naturally-aspirated Saab.
Through careful design and by including such advanced technologies as balance shafts and Direct Ignition, Saab engineers ingeniously blended the responsiveness of a larger, multi-cylinder engine with the efficiency and elegant simplicity of a four. Saab 90005 owners will therefore be able to take
full advantage of the improved performance and refinement that the 2.3 liter engine offers without suffering the compromise of increased weight and power consumption that normally accompanies the presence of additional cylinders.
The 9000S embodies the traditional Saab virtue of a hatchback design, which provides the practicality of a 60/40 split fold-down rear seat. The “flexible”, hatchback body configuration offers so much carrying capacity that it approaches the utility of a station wagon, with up to 56.5 cu. ft. of luggage space with the rear seat completely folded. The 90005 enjoys the distinction of being the only European car of its kind to be classified as a “Large” car by the
Environmental Protection Agency (EPA), and proves that sportiness and spaciousness are not mutually exclusive.
Standard amenities in the “Large” car cockpit include air conditioning with a ventilation air filter, a power tilt/slide steel sunroof, central locking, power windows and mirrors, an integrated theft alarm and an 80-watt, AM/FM stereo cassette with eight speakers and anti-theft circuitry. An optional
Leather Package is available which features leather seating surfaces, a driver’s side power seat, a power tilt/slide glass sunroof and fog lights.
Saabs have always been developed with the understanding that a lightweight vehicle with its significant masses concentrated around the car’s center of gravity will be more agile and have a greater tendency to follow the road than a car of heavier and more cumbersome proportions. Front-wheel drive with a
lightweight and compact, yet powerful four cylinder engine are typical ingredients of today’s Saab car concept, in which the interaction of driver and machine is of critical importance. Saab engineers therefore combined space-saving and effective McPherson front struts with a stabilizer bar and power rack and pinion steering in the 90005 to ensure clear and concise feedback between the driver and the vehicle, and the vehicle and the road. Eccentrically mounted coil springs and gas-charged shock absorbers are also incorporated, along with equal—length axle shafts to contribute to the this driver-car dialogue.
At the rear, a lightweight beam-type axle is specified, as is a stabilizer bar, a low-level Panhard rod, coil springs and gas—charged shock absorbers. The combination is simple, yet extremely effective and such an innovative suspension philosophy ensures that unsprung weight will be kept to a minimum to
provide a high level of ride comfort and stability. The end result is an optimum balance of all chassis elements through a concise and calculated engineering approach which gives the 9000S its fun·to·drive and predictable character.
For 1990, every Saab includes a driver’s side air bag and anti-lock brakes (ABS) as standard equipment —— whenever possible, Saab safety proficiency and suggested list price are not mutually exclusive either.
The 9000S is constructed with heavy—gauge steel and is reinforced in such a manner that the driver’s compartment is virtually surrounded by a sturdy safety cage. At the front and rear, large crumple zones are designed to absorb much of the force in the event of an impact before it can reach the
interior, and the doors contain rigid guard-beams. This is why the Saab 9000 was shown to have the lowest overall injury experience of any car in its size category in the recently released study by the Highway Loss Data Institute (HLDI), a non- profit, public service organization comprised of 266 insurance companies.
Forgiving handling behavior which corrects minor driving error instead of amplifying it, three—point inertia reel seat belts for all outboard seating positions with emergency pretensioning for the front passenger position and adjustable B-pillar anchor points, a well positioned fuel tank in a protected location and a heavily-padded interior for effective impact absorption are all innovative design considerations which protect Saab drivers and their passengers and make the 90005 one of the safest cars available in the United States today.
The 9000 CD
Saab‘s balanced engineering approach recognizes that preferences exist among buyers with regard to body design, so the new 2.3 liter naturally-aspirated engine is also available in a 4-Door Sedan for those who favor a more formal profile. The 9000 CD is designed with similar virtues as the 90005, and
like the 5—Door Hatchback, it is endowed with the same Saab “soul.”
The 9000 CD 4-Door Sedan shares the 5-Door platform, chassis, powertrain and basic body structure. The Sedan configuration provides complete isolation of the passenger compartment from the luggage area for even greater refinement, since the rear seatback is fixed and the parcel shelf is permanently installed. Carrying capacity has not been overlooked and the 9000 CD offers greater cargo volume than any competitive sedan in its sales class. A cargo portal is
provided behind the rear center armrest for especially long items, and Saab’s traditional low—liftover threshold is also featured.
The 9000 CD’s rear window is fixed so that the glass pane becomes a structural member. The car’s high level of safety is enhanced by a headlamp wiper/washer system which Saab pioneered in Europe to keep the headlamp lenses clear even in the worst weather conditions. The 4-Door Sedan also includes side guidance reversing lamps and a remote trunk release.
In addition to the Leather Package which includes leather seating surfaces, a driver’s side power seat, a power tilt/slide glass sunroof and fog lights, the only options available are a A-Speed automatic transmission and clear-coat metallic or black paint. A 5-Speed manual transmission is standard equipment.
Both the 90005 and the 900000 are available from Saab’s 363 dealers, nationwide.

SAAB 9000 TURBO SERIES FOR 1990
EPA Classifies 9000 Series As European “Large Car” Saab’s long established tradition as an automotive engineering innovator continues for the 1990 model year with the 9000 Turbo series. Like all other Saab‘s, both the 9000 Turbo 5-Door hatchback and 9000 CD Turbo 4-Door Sedan include a driver’s side air bag and anti-lock brakes as standard equipment to supplement each car’s high level of occupant protection. In addition, all 9000 Turbos incorporate Saab’s patented Direct Ignition System to improve engine performance and driveability.
9000 CD Turbo
The flagship of the 9000 fleet is the 9000 CD Turbo 4-Door Sedan. More than six inches longer than the 9000 5-Door Hatchback, the CD shares the 5-Door’s chassis, turbocharged engine and basic body structure. The wheelbase of the CD is the same as the 5-Door. The additional length is found primarily in the nearly 20 cubic—foot capacity trunk. Like all 9000 models, the 9000 CD Turbo is classified as a “Large Car” by the U.S. Environmental Protection Agency (EPA). The 9000 CD is the only European sports sedan to be so rated. The CD’s sedan configuration allows for complete isolation of the passenger compartment from the luggage area for a quieter and more luxurious ride, especially for rear seat occupants. Since the rear seatbacks are fixed and the parcel shelf behind them is permanently installed, noise from the cargo area does not intrude into the passenger area. Saab engineers were able to increase the torsional rigidity of the already structurally stiff 9000 5-Door’s chassis by designing the 9000 CD with a fixed backlight so that the rear glass becomes a structural member. For 1990, the 9000 CD Turbo’s amenities have been raised to an even higher level with the refinement of the car’s standard Automatic Climate Control (ACC). Improvements to this second generation climate control system include new temperature sensors; an “Off” switch and easy—to-recognize international symbols in place of words. The 9000 CD Turbo, like all other Saabs in 1990, is equipped with a driver’s side air bag as standard. To further improve the already high level of safety, the Saab 9000 CD Turbo has a headlamp wiper/washer system to keep headlamp lenses clear in all weather conditions.
Engine performance and driveability in all weather is also improved through the use of Saab’s Direct Ignition system, fitted to the 9000 CD Turbo’s 2.0 liter engine. This ignition system ensures clean-firing, powerful ignition sparks without voltage loss or misfire. The computer-controlled, distributorless ignition system has four small, highly efficient ignition coils — one attached directly to each spark plug. Continuing to develop turbocharged, passenger car engine
technology, Saab engineers have fitted all 1990 Saab 9000 Turbos with a new, reduced inertia Garrett T25 turbocharger. This unit offers enhanced low speed engine response and improved overall performance, especially when mated to Saab’s four-speed overdrive automatic transaxle. For 1990, all 9000 Turbos are equipped with Saab’s 2.0 liter engine and are rated at 165 hp at 5,500 rpm and 195 ft.-lbs. of torque at 3,000 rpm. Standard equipment in the 9000 CD Turbo includes leather seating surfaces, and electrically-controlled driver and front passenger seats with built-in, rheostat-controlled seat
heaters. The rear seat has a fold-down armrest that conceals a pass—through port to the luggage compartment to accommodate long loads, such as skis.
Other standard amenities for 1990 include a remote deck lid release (CD Turbo only), electrically-operated windows with a one—touch feature for both front windows, as well as an electrically-operated sliding glass moonroof with a tilt—up feature and sunshade, remote-control, heated, electrically-
adjustable outside mirrors, central locking with integral theft alarm and a premium sound system complete with electronic-tuned anti—theft AM/FM—stereo cassette, amplifier/equalizer and eight speakers. The only extra cost options are the four-speed automatic transmission and clear—coat metallic or black paint.
The Saab 9000 Turbo 5-Door Hatchback receives the same upgraded Automatic Climate Control system for 1990 and Saab Direct Ignition as the 9000 CD Turbo. In addition, the ride attitude of the Turbo 5-door is maintained under all load conditions through the use of the same self-leveling Boge Nivomat rear shock absorbers as the 9000 CD Turbo. High speed 195/65 VR 15 tires are also specified on the hatchback, along with accompanying CD Turbo chassis refinements. The 5-door Turbo models benefit from one-touch open front power windows. In addition, the rear hatch design of the five- door model has been refined to reduce opening effort. Standard equipment for 9000 Turbo 5-door models includes a driver’s side air bag, leather seating surfaces, eight-way power seats for both driver and front passenger, electric sliding/ tilt glass moonroof, fog lights, and an electronic-tune AM/FM- cassette stereo with 80-watt amplifier and seven band equalizer with anti-theft circuitry.
Passenger Security And Ride Comfort
Like all Saabs before it, the Saab 9000 is a front—wheel- drive car with a suspension that has been designed for predictable and nimble handling regardless of its load. All 9000s offer excellent stability and traction in slippery conditions with 60 percent of the weight over the front drive wheels. The engine in the 9000 is mounted transversely, ahead of the front wheels. All Saab 9000 Turbo’s have double-overhead camshaft, 16- valve, 2.0 liter engines with electronic fuel injection. The engine is equipped with Saab’s revolutionary Automatic Performance Control (APC) and Direct Ignition (DI) systems. The engine can be mated to either Saab’s five-speed manual transmission or an optional four-speed overdrive automatic, with fuel saving “split torque” in third gear and direct drive in fourth. Saab’s engineers installed a space-saving, effective MacPherson-strut, stabilizer bar front suspension in the 9000. The eccentrically mounted coil springs and gas-charged shock absorbers offer over seven inches of travel. Equal-length axle shafts drive the front wheels. Steering is power-assist rack
and pinion, with 3.2 turns lock-to-lock. The simple, effective rear suspension consists of a light- weight beam—type axle, with a stabilizer bar, separate coil
springs and gas-charged shock absorbers, which are self- leveling. The rear axle is mounted by leading and trailing arms as well as a Panhard rod. All Saabs are equipped for 1990 with a four-wheel anti-lock disc brake system. Fully integrated, the anti-lock system (ABS) was jointly developed by Saab and Alfred
Teves (Ate), GmbH, to produce short stopping distances under slippery conditions and to maintain steering control in emergency situations. The 9000 has so much interior space it is the only European sports sedan or hatchback to be classified as a “Large Car” by the EPA.
This large interior is designed with Saab‘s traditional consideration for sound ergonomics, comfort, and safety. Therefore, equipment that is standard on all 1990 Saab 9000s ‘ includes electrically adjustable, heated outside mirrors and power windows — with a one-touch open feature for both driver
and front passenger — and rear window safety lockout to prevent children from inadvertently opening the rear windows. Rear doors are also equipped with child safety locks to prevent children from opening them from inside the car.

SAAB FOR 1990
Saab’s 2.3 Liter Engine Marks 40 Years Of Innovation, Not Imitation
ORANGE, Conn. — Since late 1949, when the first Saab car rolled off the assembly line in a Swedish factory that had just been converted from aircraft manufacturing to car production, Saab has continued to dedicate its design expertise to optimize performance, ensure occupant and environmental safety, and pioneer engineering innovations.
Although many of the innovations that Saab is known for — dual diagonal braking, impact absorbing bumpers, and front-wheel- drive to name a few —- are now common in the auto industry, today, the spotlight is on Saab’s new 2.3 liter, 150 bhp naturally- aspirated engine, which is the high-performing and low-polluting powerplant for the 1990 Saab 90005 and 9000 CD. It is equipped with twin, counter-rotating balance shafts, four valves per cylinder, and twin overhead camshafts with maintenance-free hydraulic valve lifters. The new 2.3 liter engine from Saab — the largest engine that the Swedish automaker has ever produced — is also Saab’s first naturally-aspirated application for its patented Saab Direct Ignition (DI) system, which thus far has been reserved
for its 2.0 liter turbocharged engines only.
Design Philosophy: A Total Systems Approach
The new engine is tailored to fit Saab’s overall design objective; to achieve optimum balance between interior space, weight, road behavior, safety, performance, and economy. Per Gillbrand, chief of advanced engine development for the Saab’s Swedish parent company explains, “The 2.3 liter engine, with
its new combustion chamber, new intake system, four valves per cylinder and cylinders as large and efficient as possible, is an exceptional engine. It is also definitely in keeping with Saab‘s interest in meeting modern transportation needs.” Instead of considering the engine as an isolated unit, Saab considers it part of the overall car concept, and just one of the elements in the traditional Saab objective of ensuring that a total systems approach is applied to vehicle development. Front—wheel drive and a four-cylinder engines are typical ingredients of the Saab car concept, that special combination of product virtues that make up the Saab “soul.” The engine is integrated with the gearbox into a lightweight, compact unit which encroaches as little as possible on the interior space, contributing to the 9000′s rating as a “Large” car by the U.S. Environmental Protection Agency (EPA). llhe power unit is mounted
low in the car, but without restricting ground clearance. The arrangement has resulted in a short, sloping hood for best possible aerodynamics and good outward visibility. Low weight is one of the fundamental demands for good economy and high overall performance, and the most critical element for
accurate and responsive vehicle handling and balance. For the past forty years, Saab has been well aware that a lightweight vehicle with its significant masses concentrated around the car’s center of gravity will be more agile and have a greater tendency to follow the road than a car of heavier and more cumbersome proportions. Under the Hood: The New 2.3 Liter Naturally—Aspirated Engine
The cast iron block of Saab’s 2.3 liter engine is totally new and offers excellent vibration dampening properties through the use of counter—rotating balance shafts, which are integrated within the block. The block is a modern design with moderate material or wall thickness. Due to state—of-the-art design and production techniques, casting accuracy is precisely controlled to provide minimized weight with excellent rigidity. The new engine is equipped with Saab’s well-known light-alloy, cross-flow, four-valve cylinder head, one of the first of its kind from the recent 16—valve technology race. It features double
overhead camshafts with hydraulic lifters, tuned intake and exhaust manifolds, and electronic/semi-adaptive fuel injection with three- way closed loop catalyst control. Since the cylinder spacing is unchanged from the previous 2.0 liter unit, the cylinder head is similar to the 2.0 liter head, but features reoptimized combustion chambers and manifold ports for the 2.3 liter application. Since all reciprocating engines inherently vibrate -— due to imbalance caused by piston inertia and the forces generated during the combustion process -— Saab has ingeniously integrated counter—rotating balance shafts into its 2.3 liter engine to make it quiet and efficient. The balance shafts rotate in opposite directions at twice the crankshaft speed and are equipped with
counterweights to virtually cancel unwanted forces. Although the balance shafts are mounted at the same distance laterally from the cylinder centerline, they are strategically mounted at different heights. This height difference ensures that the shafts are as effective as possible during the broadest engine operating range. The balance shaft housings are cast directly into the engine block, resulting in a compact, lightweight design, devoid of oil leak risk.
The presence of balance shafts allowed Saab to increase engine displacement to 2.3 liter from its 2.0 liter naturally-aspirated predecessor, without the vibration concerns that are normally associated with such a large four cylinder engine. The result is that the advantage of increased performance and comfort can be enjoyed without suffering the compromise of increased weight and power consumption that accompany additional cylinders. The fact
that the block is cast in iron also contributes to the engine’s excellent vibration dampening characteristics. The entire 2.3 liter powertrain is mounted on a discreet subframe which includes hydraulic engine mounts to provide even greater isolation from vibration.
In summary, Saab engineers have ingeniously blended the responsiveness and smoothness of a larger, multi—cylinder engine with the efficiency and elegant simplicity of a four, to achieve the Saab objective for optimum balance of all vehicle design elements.
High Torgue for More Useful Mid-Range Response Under normal driving conditions, torque is a more important engine parameter than horsepower, since it influences acceleration and overtaking performance. Horsepower more specifically governs top speed.
The overriding engineering challenge during the development of the 2.3 liter naturally-aspirated engine was, therefore, to provide high torque over a wide operating range while maintaining traditional Saab road holding and packaging efficiency. Bore diameter was maintained at 3.54 in. (90mm), as was cylinder spacing at 4.06 in. (103mm), which is equivalent to the 2.0 liter engine, so overall engine length is unchanged. The stroke was increased from 3.07 in. (78mm) to 3.54 in. (90mm), resulting in a torque peak of 156 ft.-lbs. (212 Nm) at 3,800 rpm. Although the new 2.3 liter represents a 15 percent increase in displacement over the previous 2.0 liter naturally-aspirated engine, the torque curve is 22 percent higher, and flat as well. Engine output for the 2.3 liter
has increased from its 130 hp, 2.0 liter predecessor to 150 hp at 5,500 rpm.
This innovative, engineering approach results in more effective and tractable engine behavior for a relaxed driving experience, since the need for gear changing is reduced. A computerized engine management system controls the electronic fuel injection and the Saab Direct Ignition (DI) system. It makes adjustments by the millisecond to ensure optimal performance and accuracy. Saab’s patented Direct Ignition system
contributes to this overall versatility. An encapsulated system with a separate coil mounted directly on each spark plug, Saab DI is virtually immune from the dangers of moisture and dirt. By generating an ignition voltage of 40,000 volts, it also enables Saab cars so equipped to shrug off cold weather.
Saab’s 2.3 liter naturally-aspirated engine is manufactured in a dedicated, state-of-the-art facility in Sodertalje, Sweden. The new engine has taken more than five years to design, develop, and test under all road and weather conditions.

SAAB FOR 1990
Innovative Technology Includes Direct Ignition System: An Intelligent Advance For “The Host Intelligent Car”
ORANGE, Conn. — Ever-tightening auto emissions standards and the simultaneous quest for improved fuel economy and performance have stimulated automotive engineers to more technological advances in the last ten years than the car has seen in the past one hundred. However, despite computerization
and other engine electronic wizardry, until now, little has been done in the area of ignition system development.
Engineers have been struggling to create systems that produce sparks powerful enough to fully ignite today’s carefully metered fuel/air mixtures while keeping the necessary underhood voltages to safe and manageable levels. The high voltages needed for proper combustion, in turn, have created the potential for voltage leaks at ignition coils, distributors and spark-plug wires. This has caused problems with driveability due to misfire as well as large amounts of unwanted electrical interference. Such interference not only causes poor radio reception, it can also create havoc for other underhood electronic components, such as engine management microprocessors.
Saab has solved these ignition shortfalls with their new patented Direct Ignition system, found on all 9000 models — the 1990 90005 and 9000 CD with the 2.3 liter naturally-aspirated engine, and the 1990 9000 Turbo and 9000 CD Turbo with the 2.0 turbocharged engine.
A team of engineers, headed by Per Gillbrand, who developed Saab‘s unique Automatic Performance Control (APC) for turbocharged engines, has created an ignition system that features individual compact ignition coils for each spark plug and no distributor or high-tension ignition wires. All of the high-voltage components are encased in an alloy cartridge that sits atop the cylinder head between the camshaft covers.
The totally insulated individual coils supply their spark plugs with a powerful 40,000 volts at the moment of ignition, enough to ensure thorough combustion for optimum performance, fuel economy and minimal emissions. The wires connecting the cartridge to the electronic control unit carry only 12 volts,
which guarantees no voltage leaks for smooth running and no radio interference.
Continuous Optimun Ignition Timing
A microprocessor controls ignition timing based on engine speed and piston position information it receives from a crankshaft sensor (accurate to within 0.5 degree, plus or minus) as well as engine load information it gets from a manifold pressure sensor and the inception of detonation from a knock sensor. The microprocessor instructs the appropriate coil to fire at the optimum moment. This use of a microprocessor and individual ignition coils actually permits constantly variable ignition timing from cylinder to cylinder, even within the same revolution of the engine.
The coils themselves are of a new, small design. They are powerful enough to step up the signal they receive to 40,000 volts to fire the spark plug. The voltage increase is done in two stages, first to 400 volts, which is stored in a capacitor.
Then, at the instruction of the microprocessor, the voltage is upped to 40,000 volts for ignition. with Saab’s cross—flow, four—valve—per—cylinder, alloy head design, the spark plug is placed centrally in the combustion chamber. The shape of the combustion chamber, combined with the powerful spark, ensures optimum combustion for efficient use of fuel.
The use of a microprocessor to initiate the spark further enhances reliability life over other distributorless ignition systems since the spark plugs in Saab’s Direct Ignition (DI) system each fire only during the compression stroke of the engine.
with the ignition coils attached directly to the spark plugs and all of the high voltage components mounted in a special alloy container atop the cylinder head, the chance for voltage leaks is virtually eliminated, as through worn spark plug wires or slight cracks in a distributor cap or insulation. The alloy
container and the cylinder head itself serve as more than ample insulation; there is no danger of electric shock for technicians by touching the system‘s cover while the engine is running. The ignition system‘s container is so designed that when unbolted for removal, the four ignition coils release their grips on the spark plugs.
Since there is no distributor cap, spark-plug wires, or exposed spark-plug cover boots, there is virtually no chance for ignition misfire due to voltage leaks, regardless of conditions. There are fewer reliability concerns as well, since there are no mechanical parts to wear. In addition, thanks to the multiplicity of ignition coils, the failure of a coil does not prevent the car from being driven. There’s a “limp—home” mode in the microprocessor that allows the car to still be
driven if there is an electronic failure in the system.
To ensure easy starts, the Saab DI has a multi-spark function. when the ignition key is first turned, each spark plug, in turn, is fired about 50 times in a fraction of a second. This rapid-fire discharge cleans and dries the spark plug electrodes to aid starting. If the engine fails to start, the system is programmed to give all the plugs a simultaneous blast of about 1,000 sparks, after the driver releases and then retries the ignition key. Once the engine has started and is idling at at least 600 rpm, the system operates in its normal, one-spark-per—cycle mode.

SAAB 900 FOR 1990
Anti-Lock Brakes and Driver’s Side Air Bag:
Standard Safety Eguigment In All Models In its last two annual reports, the Highway Loss Data Institute (HLDI) reported that the Saab 900 had the lowest
Overall Injury experience, in both the 2—Door and 4-Door categories for small cars. Additionally, the 900 hatchbacks were rated lowest in small car Severe Injury experience. The HLDI reports reflect the accumulated loss experiences of most American insurance companies, and also list the Saab 9000 as having the lowest Overall Injury experience in the mid-size sports and speciality model category. For 1990, all Saab 900 cars are even more protective of
their drivers and passengers with the addition of anti-lock brakes and a driver’s side air bag (Supplementary Restraint System) as standard equipment, thus offering an even higher level of active and passive safety. The 1990 Saab 900 series consists of eight models: The 900 3-Door hatchback and 4—Door sedan; the luxury-trimmed 900S hatchback and sedan; the high-performance 900 Turbo 3-Door and 4-Door; the sensuous Saab 900 Turbo Convertible; and the limited-production 900 Turbo SPG —- for 1990 the most powerful Saab ever offered on the American market.
In addition to standard anti—l0ck brakes and driver’s side air bag, all Saab 900 models for 1990 also come equipped with a larger fuel tank. All are powered by a four—cylinder, double overhead camshaft, 16—valve, 2.0 liter engine, in either naturally-aspirated or turbocharged form.
900 Turbo SPG
The most powerful Saab ever-offered, the limited—production SPG hatchback gets even more power and improved turbo response for 1990. The SPG receives a new turbocharger that improves overall performance, thanks to its recalibrated low-end behavior. This translates to better throttle response at lower engine speeds along with higher top speed capability. with its new turbocharger, specially calibrated APC unit and engine management system, the SPG delivers 175 hp at 5,500 rpm (10 more hp than in 1989) and 195 lbs.-ft. of torque at 3,000 rpm. The SPG comes with Saab’s five-speed manual transmission only.
To handle the extra power, the Turbo SPG also has a uniquely calibrated and lowered suspension for improved handling and special, high—speed V—rated, low profile tires on unique wheels. The SPG’s four-spoke, leather-wrapped air-bag steering wheel is also new for 1990. Besides different wheels, tires and more power, the SPG is clearly recognizable by its aerodynamic lower-body panels. The 900 SPG is available in distinctive Talladega Red or traditional
Saab Black. As befits a limited production flagship, there are no extra cost options. The gray leather interior, four—spoke leather—wrapped airbag steering wheel, electric sliding steel sunroof, fog lights and aerodynamic lower-body panels distinguish the SPG as a unique sport variant.
900 Turbo Convertible
The exclusive 900 Turbo Convertible is based on the Saab 900 Turbo model but was designed from inception as a convertible. Unlike convertible versions of other cars, Saab builds the convertible on a dedicated production line at the company’s Uusikaupunki, Finland factory. This in—house manufacturing
method ensures that the car meets all of Saab‘s highest technical standards — including those for the rigidity of body and chassis platform. The convertible has extra reinforcements at the windshield pillars, door sills, behind and under the rear seat and in the doors’ rear pillars. Powered by the same 160-hp, 16-valve, turbocharged 2.0- liter, four-cylinder engine as other Saab 900 Turbo models (except the SPG), the convertible has front and rear electrically-powered windows as standard equipment. The cloth- covered top, with integral headliner and electrically—defrosted glass backlight, is electro-hydraulically powered and well insulated against outside road noise. The top is controlled by a dash—mounted switch which will only allow raising and lowering
of the top when the car is parked and the emergency brake set. Standard equipment on the 900 Turbo Convertible for 1990 includes leather seating surfaces, fog lights, an anti-theft system, and a new four-spoke, leather-wrapped air bag steering wheel, as well as a driver’s-side air bag, anti—lock brakes and an enlarged (18 gallon) fuel tank. The only options are automatic transmission and clear-coat metallic or black paint.
For 1990, Saab offers two versions of the 900 Turbo, a 3-Door Hatchback and 4-Door Sedan, in addition to the limited production SPG and the exclusive convertible. Like the rest of Saab’s 1990 line, all 900 Turbos are equipped with anti-lock brakes and driver’s side air bag as standard equipment. In
addition, for 1990 all 900 Turbos benefit from an increased cruising range, thanks to the larger (18 gallon) fuel tank. All Turbos feature leather seating surfaces, electric steel sunroof and windows —— including one touch operation on the driver’s window. The 4-Door models have a safety lockout switch
to prevent children from operating the rear windows. All Saab 4-Door Sedans also have child safety locks on the rear doors to prevent children from opening the doors from inside the car. Other standard equipment for all 1990 900 Turbos include fog lights, air conditioning, and an electronic-tuned AM/FM-cassette
stereo with an 80-watt amplifier, seven-band equalizer and anti- theft circuitry. Options include an automatic transmission and clear-coat metallic or black paint.
900 and 900S
The 900 and 9005 receive their power from a naturally- aspirated version of 5aab’s renowned dual—overhead camshaft, 16- valve, 2.0—liter, four cylinder engine. with electronic fuel injection and ignition timing controls, the engine delivers 128 hp at 6,000 rpm and 128 lbs.-ft. of torque at 3,000 rpm.
New standard features for both the 1990 900 and 900S include anti-lock brakes and driver’s side air bag, while leather seating surfaces, an electric steel sunroof and fog lamps are included in the 9005. In addition, air conditioning, central door locking, and an electronic-tuned AM/FM-cassette stereo with
80-watt amplifier and anti-theft circuitry is included in all 900 and 900S models. Options on 900 and 900S models include automatic transmission and clear—coat metallic or black paint.
The Saab Soul
The essence of every Saab is its proven front-wheel drive technology. All 900s have their front wheels driven by a longitudinally placed double overhead camshaft, four—valve per cylinder, 2.0-liter engine, with electronically-controlled fuel- injection and ignition timing and hydraulic engine mounts. That
engine develops 128 hp in its naturally-aspirated state and 175 hp in its highest form of tune in the SPG Turbo. All 900s’ front driving wheels have a fully independent suspension with upper and lower wishbones with pivot mounted coil springs, separate gas-charged shock absorbers and a stabilizer bar. The non·driving rear wheels are mounted via a lightweight axle tube that is located by five links — two forward arms, two rearward arms, and a Panhard rod -— to keep the rear wheels parallel under all conditions. There are separate coil springs, gas—charged shock absorbers and a stabilizer bar in the rear as well. Saab continues as a leader in automotive safety by engineering cars for accident avoidance — active safety -— and occupant protection — passive safety. Saab 900s offer excellent all—weather traction and stability thanks to Saab’s continuing refinement of front-wheel-drive. All 900s have 60/40
front/rear weight distribution; when fully loaded, the weight distribution is still front biased, at 51/49, to ensure that the car handles predictably regardless of load. All 900s for 1990 have power-assisted, rack and pinion steering and four—wheel, anti-lock disc brakes as standard equipment.
Saab’s anti-lock braking system was developed jointly by Saab and Alfred Teves (Ate), GmbH, to provide shorter stopping distances for all drivers under slippery conditions. In addition, the system gives shorter stopping distances under most dry conditions as well. Most importantly, with anti-lock brakes the driver retains steering control under emergency stopping conditions, a critical life saving feature. Saab 900s have S- mph deformable bumpers as well. An equally important ingredient, passive safety has been well considered in the driver’s environment of every Saab 900. Developed over the years to provide maximum safety, comfort and driver awareness, the padded passenger compartment of all 900s feature heated driver and front-passenger reclining bucket seats and air conditioning. In addition, for 1990, three—point shoulder harness safety belts at all outboard seating positions are supplemented in every model by a driver’s side air bag.
