With relatively few changes, the 2009 Acura RDX retains the sporty appeal and modern upscale styling of the 2008 model. Strong points on the vehicle include a turbocharged 4-cylinder engine that musters 240 horsepower and some of the best crash test scores in its class. A plethora of standard luxury features also serve to bolster the appeal of the 2009 RDX, with leather upholstery, heated front seats, all-wheel drive and dual-zone automatic climate control all coming standard. New for the 2009 model is a standard 4-way power passenger seat and an improved real-time traffic system. EPA-estimated fuel efficiency is 22 mpg on the highway. Acura offers a 4-year/50,000-mile warranty for the 2009 RDX.
