What’s the best thing about the 2007 Acura RDX? Performance is the 2007 Acura RDX’s calling card. The turbocharged, four-cylinder engine, which delivers 240 horsepower and 260 lb.-ft. of torque, along with Acura’s SH-AWD system and a svelte curb weight of under 4,000 lbs., gives the RDX a very crisp and fun driving character. It’s a thoroughly enjoyable vehicle to drive.
