As engineering technology has improved, smaller engines are capable of delivering more efficiency and power than ever. That is why General Motors is adding two new three-cylinder engines to its U.S. lineup for the first time in over 20 years. These engines will make their debuts on the 2021 Chevrolet Trailblazer and the 2020 Buick Encore GX.
With advanced turbocharger technology, these three-cylinder engines will deliver similar outputs to four-cylinder engines. The units will come with features like an active vacuum system, an electrically assisted wastegate system, and an electrically driven water pump. All these features, plus the 40-pound weight difference, should help deliver superior efficiency and performance over the four-cylinder engines.
The last time GM offered a three-cylinder, it was in the 2000 Chevrolet Metro. This 1.0-liter three-cylinder engine was only rated at 55 horsepower. By comparison, GM’s overseas three-cylinder options deliver around 155 horsepower. GM has yet to announce the official output ratings of the new 1.2- and 1.3-liter engines.
All of us at Sunrise Chevrolet Buick GMC at Collierville are we are excited to experience these new engines for ourselves. The 2020 Buick Encore GX should arrive within the next couple months, while the 2021 Chevrolet Trailblazer is set to debut later this spring. We’d love to see you here to test drive either — or both — of these vehicles.
