The Chevrolet Sprint (1985-88) and the Geo Metro (1989-93) are very similar vehicles. The standard engine is a 1.0L SOHC 3-cylinder engine backed by either a 5-speed manual or 3-speed automatic transaxle.
Several variations of the Sprint/Metro have been built during the model run. In 1987, a turbocharged version of the 1.0L engine was made available. The turbocharged engine provided significant gains in horsepower and torque over the normally aspirated engine, while still providing fuel efficiency and driveability. It also introduced Electronic Fuel Injection (EFI) to the Sprint/Metro line-up. EFI has been used exclusively since 1988.
The other major variation on the Sprint/Metro line was the introduction of the convertible in 1990.
