The 2026 Buick Encore GX is built around a confident 1.3-liter Turbo engine that balances responsive performance with impressive efficiency-perfect for the everyday driver.

All Encore GX trims are powered by this capable engine. The Preferred trim pairs it with an automatic transmission, while Sport Touring and Avenir trims feature a 9-speed automatic transmission for enhanced performance and refinement.

Fuel economy is a strong suit: the Encore GX delivers GM-estimated 29 mpg city and 31 mpg highway. That efficiency means fewer fill-ups and lower fuel costs over time, without sacrificing the spirited driving feel you expect from a Buick.

Combined with the compact SUV's versatile five-passenger seating and flexible cargo space (thanks to 40/60 split rear seats), the Encore GX is designed for real-world practicality. Whether you're commuting, running errands, or heading out for an adventure, the efficient Turbo engine gets you there confidently.
