A Powerful Drivetrain

The Buick Encore GX has a lightweight yet powerful engine that helps maintain its impressive gas mileage. The standard ECOTEC 1.2L Turbo engine generates 137 horsepower and 162 lb-ft of torque, so you’ll be gliding through busy traffic with ease.

There’s also an available ECOTEC 1.3L Turbo engine that produces 155 horsepower and 174 lb-ft of torque. Plus, the Selectable Stop/Start system helps further improve fuel economy.

The standard Continuous Variable Transmission also helps this vehicle’s fuel efficiency. Unlike a traditional transmission, this system automatically changes gears through the use of a pulley system, helping limit fuel consumption.

If you commute into the city during the week or like taking long road trips, the more fuel-efficient front-wheel-drive configuration may be the better choice for you. However, if your adventures ever take you off-road, you may want to consider the available all-wheel drive system that still has a good fuel economy but also provides more traction when you drive over uneven terrain. Here’s a breakdown of the EPA-estimated fuel economy for the Encore GX AWD trims:

With this much space, you and your passengers will be comfortable during long drives.

Plus, there’s 23.5 cubic feet of space behind the second row, so you’ll have plenty of room for everyone’s bags and other belongings every time you hit the road.
