What is the difference between a Chevy Metro and a Geo Metro?

Answer 1

98-01 are Chevy, previous years are Geo, still both engines were make by Suzuki.

'The 3cyl model engines are different from the crank bolt pattern, the Geo was a 4 bolt, and the Chevy a 5.'

From 1998,

"The Metro now carried the Chevrolet nameplate, along with new front and rear fascias and a SOHC 16v design I-4 1.3L engine with a horsepower increase of 12%.

Electronic ignition replaced the distributor, and MPFI (Multiport Fuel Injection) replaced the TBI (Throttle Body Injection). The new motor offered more HP, torque, and higher fuel economy. This I-4 engine replaced the older 8v 4 cylinder, but the 3 cylinder engine remained unchanged." from Wikipedia "Geo Metro."

You may notice that 3-speed automatic transmissions are much more common for Chevy Metros than Geo Metros, as well as four cylinder engines. Standard transmission and 3 cylinder engines seem to be less common Chev Metros.

A 4 cylinder engine model option was introduced in 1995 into the Geo Metro line. 4 cylinders were standard for Suzuki Swifts even before 1995.
