Spawned from the Chevrolet Trax, the Buick Encore considers itself the Trax’s luxurious alter ego. This little urban SUV is proof positive that luxury comes in all shapes and sizes. With equipment worthy of large luxury cars, the Encore is powered by the same engine as the Trax, namely a 1.4L 138-hp four-cylinder and is currently one of the only sub-compact luxury SUVs on the market.
