What is the Porsche 928?

The 928 is a two-door grand touring coupe, built for comfortable long-distance travel as well as lively driving. Its front-mounted V8 and flowing shape gave Porsche a different kind of sports car from the rear-engined 911. Introduced in 1978, it stayed in production through 1995.

A rear-mounted transmission connected to the engine by a driveshaft gave the 928 its transaxle layout. Porsche also fitted its distinctive Weissach rear axle, designed to help the car remain composed through bends.

Generations and engines

The 928 had one generation, named 928, sold from 1978 to 1995. Over that time, Porsche developed the original V8 coupe into versions with larger engines, while retaining the front-engine, rear-transaxle layout.

In the United States, EPA figures cover petrol versions with engines from 4.7 L to 5.4 L for model years 1984–1995. Canada’s NRCan figures cover 5.4 L petrol versions for 1995.
