The very nervous 3-cylinder engine found in the Chevrolet Sprint Turbo was part of the very successful and long-lived Suzuki G engine family.
How many engines can you think of that were available in both three- and four-cylinder form? The Suzuki G was made from 1984 well into the current century, and it powered a bewildering array of Suzuki and General Motors machinery. The Holden Barina! The mullet-friendly Geo Tracker! Even the Pontiac Firefly came with G power, and we mustn't forget the Airtrikes.net ultralight aircraft freaks.
