New 2016 Chevrolet Colorado Z72 review and model. Get more information about 2016 Chevrolet Colorado Z72 with price, specs and release date for US, UK, Canada and Australia. The 2016 Chevrolet Colorado Z72 is heading to get a lightweight body which will offer great performance on a variety of terrains. There were some rumors about the powertrain which claimed that the truck will be driven by a 4.3-liter V6 EcoTec3 engine. The concept model released at the 2014 Los Angeles Auto Show experienced a turbocharged 2.8-liter Duramax four-cylinder diesel engine. Even though the V6 EcoTec3 gasoline seems to be just the correct selection for a mild mid-size pickup truck, the 2.8-liter Duramax turbodiesel is an similarly appealing option.
