Saab engines were built at Saab-Scania in Trollhättan, Sweden; sometime after that, the engine building/production was taken over by General Motors Powertrain Europe around the year 2000. As it happens, Saab developed all their own engine designs, including the inline-four engines like the B-series and the Saab H engine, which defined Saab's engine lineup for decades. Their pioneering work on turbocharging in family cars, in fact, helped influence performance engine design across Europe. The Saab H engine, first introduced in 1981, was a complete overhaul of the slant-four, retaining its distinctive canted block layout. From then on, it essentially became the base design for all Saab's four-cylinder engines up to 2009. As for the best of the best Saabs out there, we're looking at cars like the 900 Turbo, the 9-3 Viggen, and the 9-5 Aero, all of which ran on Saab's high-output B-series turbo engines, which had been tweaked to deliver a pretty impressive 200-250 hp.
The two-stroke, V4, and H-engine families, before adopting GM’s Ecotec units under the GM-Saab alliance. Some of the Saab engines include the Saab 9 3 Turbo Engine, which is Saab’s 2.0- and 2.3-liter turbocharged inline-four engines, known as the B204 and B235 series, developed in-house in Trollhättan before General Motors’ full integration. Pre-GM Saabs, especially the 900 and early 9-3, maintain strong reliability ratings due to overbuilt mechanical components and simple turbo systems. The Saab 900 engine is used in the H-engine series, ranging from naturally aspirated 2.0-liter units to turbocharged 2.1-liter variants, built in Sweden between 1978 and 1993.
Under the GM Powertrain collaboration, the B204 Saab engines were adapted for the Opel Vectra B and Vauxhall Vectra models, using identical block design and sensor layout. The Saab 9-3 B207 has shared its design with GM’s Z20NET engine found in the Opel Vectra C, Opel Signum, and Chevrolet Malibu, allowing direct fitment between these cars. Apart from these, the Saab’s 3.0 L V6 B308E naturally aspirated engine could also be used in the Opel Omega B and Cadillac Catera.
Generally used Saab transmissions for sale, including F35 and F40 units, are commonly available through GM-sourced vehicles such as the Opel Astra, Vectra, and Saturn Ion, which share the same bell housing and spline pattern. The Saab 9-5 transmissions are available in both five-speed manual and four- or five-speed automatic transmissions supplied by Aisin Warner, designated AW55-50SN, shared with Volvo and Opel models of the same era. The Saab 9-3 Transmission (2003–2011) used the F40 six-speed manual gearbox in 2.0T and 2.8T models, and the classic Saab 900 transmissions are in a transaxle design where the transmission sits beneath the engine and shares oil with the engine, a unique feature inherited from the Saab 99 design.
