3-Cylinder Engines Surge in Popularity as SUV Sales Rise, 6- and 8-Cylinders Decline

Since 2019, sales of 3-cylinder engines have surged from 0% to over 6% of the U.S. market.

Meanwhile, sales of 6- and 8-cylinder engines have been declining.

The growth in 3-cylinder engines is driven by rising demand for small SUVs like the Buick Encore GX.

4-cylinder engines remain the most popular at 57.2% share.

6-cylinder share has fallen to 26.8% as manufacturers offer more powerful yet efficient engines.
