Engineers have gotten good at maximizing power from small engines. Many four-cylinder engines available today are more powerful than larger engines that were available decades ago. Now, we have learned that General Motors is adding two new three-cylinder engines to its lineup.
The last time GM offered a three-cylinder engine was on the 2000 Chevrolet Metro. This was a 1.0-liter engine with only 55 horsepower. The modern versions will be much better than that and will come in 1.2- and 1.3-liter displacements with attached turbochargers. The 1.3-liter engine delivers 155 horsepower, while the 1.2-liter option is expected to have an output near 137 horsepower.
Along with their impressive power ratings, these engines should be more efficient. When compared to a larger four-cylinder engine, these engines weigh about 40 pounds less. The weight savings combined with more efficient engine technology should help save fuel. GM has yet to release fuel efficiency ratings, but we expect them to be better than the EPA-estimated 27 mpg combined with the 1.4-liter four-cylinder engine on the current 2020 Buick Encore.
Both of these engine options will be available in the new Buick Encore GX and the Chevrolet Trailblazer. The Buick Encore GX will go on sale here at Transwest Buick GMC by the end of March.
