The third generation of the Chevrolet Colorado (code name GMT595) marks a major technological and mechanical breakthrough for the midsize pickup segment. Launched for the 2023 model year, it abandons the engine diversity of the previous generation (which offered a naturally aspirated 4-cylinder, a V6, and a diesel) to focus exclusively on a turbocharged 2.7L 4-cylinder block in North America. Note on the targeted Diesel engine: The famous 2.8L Duramax (LWN) diesel engine was removed from the North American catalog with the arrival of this 3rd generation (GMT595). However, it remains an essential benchmark on the used market (Gen 2: 2016-2022) and continues to be offered on international markets (notably in South America under the name Chevrolet S10). This sheet therefore details the 2.8L D
The 3rd generation Chevrolet Colorado (GMT595) is an extremely accomplished midsize pickup dynamically and technologically. If you are specifically looking for the 2.8L Duramax diesel engine, you will have to turn to the previous generation (2016-2022) or export markets (S10), where this engine shines with its reliability, torque, and longevity (despite some quirks of the emissions control system). For the new 2023+ model, the 2.7L Turbo 4-cylinder brilliantly replaces the diesel in terms of pure performance, although it consumes more under load. Initial reliability data (J.D. Power, ADAC) places the Colorado in the upper average of its category. However, the numerous assembly and software recalls on the 2023 model year urge caution: favor a 2024 model or ensure that all recall campaigns (AEB camera, wheel hubs, fuel pump) have been rigorously applied by the dealer.
