The Saab 900 I 2.0 EMS, produced between 1978 and 1980, represents the initial iteration of Saab’s hugely successful and influential compact car. This model, a four-door sedan, was a pivotal vehicle for Saab, establishing many of the design and engineering philosophies that would define the brand for decades. The 900 was designed to replace the Saab 96, offering a more modern and spacious package while retaining the quirky character and focus on driver safety that Saab was becoming known for. Initially sold primarily in Europe, the 900 I laid the groundwork for Saab’s eventual, albeit limited, entry into the North American market.
The Saab 900 I 2.0 EMS: A Legacy of Innovation
The first generation Saab 900, designated the 900 I, was a significant departure from its predecessor. While the 96 was based on a pre-war design, the 900 featured a completely new platform, offering improved comfort, handling, and safety. The “EMS” designation refers to the Bosch electronic fuel injection system, a relatively advanced feature for the time, contributing to improved performance and fuel efficiency compared to earlier carbureted models. The 900 I quickly gained a reputation for its robust build quality, distinctive styling, and a loyal following among enthusiasts who appreciated its unique character.
Engine & Performance
The heart of the Saab 900 I 2.0 EMS is a 1.985-liter (121.13 cubic inches) inline-four cylinder engine. This naturally aspirated engine, identified by the code BI 20, produces 118 horsepower at 5500 rpm and 167 Nm (123.17 lb.-ft.) of torque at 3700 rpm. The engine features a dual overhead camshaft (DOHC) valvetrain with two valves per cylinder. Power is delivered to the front wheels via a four-speed manual transmission. The 900 I’s front-wheel-drive configuration, while not uncommon today, was still relatively novel in the late 1970s, contributing to its distinctive handling characteristics. The car achieves a maximum speed of 169 km/h (105.01 mph). The weight-to-power ratio is 9.9 kg/Hp, and the weight-to-torque ratio is 7 kg/Nm. The engine’s power per liter is a respectable 59.4 Hp/l for the era.
Design & Features
The Saab 900 I’s design was instantly recognizable, characterized by its aerodynamic shape and distinctive front grille. The body style is a traditional four-door sedan, offering seating for five passengers. Safety was a paramount concern for Saab, and the 900 I incorporated several features designed to protect occupants. These included a reinforced safety cage, energy-absorbing crumple zones, and a column-mounted gear lever (intended to reduce knee injuries in a collision). The interior was functional and driver-focused, with a clear instrument panel and comfortable seating. While not lavishly equipped by modern standards, the 900 I offered features such as a heater, ventilation system, and basic instrumentation. The car’s relatively large fuel tank, with a capacity of 58 liters (15.32 US gallons), provided a reasonable driving range. The 185/65 R15 tires, mounted on 15-inch wheels, provided adequate grip and ride comfort for the time.
