The 3.5-liter V6 is the first six-cylinder offered in an RDX. The naturally aspirated engine boasts another first for Acura: variable cylinder management. The purpose of this system is to save fuel by deactivating cylinders when they're not needed. The engine has 273 horsepower and 251 pound-feet of torque. Fuel economy is 20 mpg city and 28 mpg highway with front-wheel drive; expect 19 mpg city and 27 mpg highway with all-wheel drive.
The RDX offers the longest list of standard equipment in the category. Key features consist of a multi-view backup camera, heated front seats with a 10-way power driver's seat, a 7-speaker audio system with a 5-inch LCD display, voice-activated text messaging (not compatible with iPhone) and Pandora Internet radio. And unlike its German-built rivals, the RDX includes keyless entry and push-button start as standard fare.
Optional features are grouped together in the $3,700 Technology Package. Highlights include a navigation system with traffic overlays, HID headlights, and one of best surround sound stereo systems in the industry, the Acura/ELS audio system designed by Grammy award engineer and producer Elliot Scheiner. Also included is the AcuraLink application hub with Zagat ratings, weather forecasts and dealer appointment reminders.
