Chevrolet Colorado

With an all-new Colorado set to go on sale in 2020 as a 2021 model, it's a safe bet there aren't many more changes in store for the current truck. For 2019, the mid-size Colorado is offered with three engines (two 4-cylinder, one V6), one of which is a diesel (2.8L turbo diesel 4-cyl.), along with two automatic transmissions (6 and 8-speed).
