Powerplant and Drivetrain
The powerplant is usually referred to as a PRV6 which is the european version of the Volvo 6-cylinder sports engine. This engine was developed jointly by Peugot, Renault, and Volvo (hence its name). The basic engine is designated as a Volvo B28F and some parts houses can cross reference parts to this engine. The engine designation is probably derived from the engine being a gasoline fueled ("bensin" in Swedish) 2.8 liter engine of generation "F." There are some subtle changes to the engine from the stock configuration usually having to do with the attached systems and slight modifications for the reversed mounting. The engine is mated with the Bosch K-Jetronic fuel injection system which generally has a good reputation.
The transmission is a Renault 5-speed manual or 3-speed automatic. The transmission is often referred to as the Renault Alpine and has been modified slightly to accommodate the reversed rear-engine configuration.
