Acura's compact luxury SUV is back for 2016 with a new look that stays true to the brand's overall style. Thanks to Acura's intelligent 4-wheel drive system, the RDX proves both civilized and comfortable. Under the hood, there's a 3.5-litre 279-horsepower V6 partnered up with a 6-speed automatic SportShift transmission. The 4-cylinder turbo hasn't been offered for a few years now.
