What do you get when you cross the street performance of a sports coupe with the four-wheel drive capability of the Acura MDX? Acura has an answer: the RD-X concept SUV.

The vehicle was designed and developed by Honda R&D Americas and is targeted to meet the needs of youthful, urban professionals, the RD-X is both "rugged city transportation and weekend sport machine".

"The RD-X is the perfect vehicle for young, active people who work hard during the week and play harder on weekends," Tom Elliott, executive vice president of American Honda Motor Co., Inc. was quoted as saying. "It has the cargo space and rugged functionality of an SUV, but with 250 horsepower and a sport tuned suspension, it also has the credentials to appeal to the serious driving enthusiast."

The RD-X is designed to be powered by a unique 250 horsepower, 4-wheel drive, hybrid powertrain that combines a high-output i-VTEC engine with an Integrated Motor Assist (IMA) system. Under the hood is a high performance 2.4-litre, 16-valve, DOHC four-cylinder engine coupled with a six-speed, close-ratio clutchless manual transmission (which was inspired by Honda’s Formula One race cars) that drives the front wheels, while the advanced IMA system powers the rear wheels.

Shifting with the clutchless manual transmission is accomplished with a paddle shifter conveniently mounted close at hand on the center console while the close-ratio design of the gearbox helps the driver extract maximum performance from the engine.

The RD-X comes with a newly developed IMA system with twin electric motors to power the rear wheels when extra driving force or traction is needed. This unique configuration increases power and distributes torque similar to an all-wheel drive SUV. Fully independent front and rear suspension, large 4-wheel disc brakes, large 18-inch wheels and 235/60R18 tires combine to provide a tenacious grip.

Design-wise, the RD-X employs a compact upper body with an aggressively raked belt line, substantial wheel flares and a unique glass roof. Also included are run-flat tires, retractable headlights and substantial bumpers.

Inside, dual front bucket seats are positioned close together rally-style to facilitate easy communication between the driver and the front passenger. Rear action seats angle outward for increased legroom and can be quickly folded forward and stowed when more cargo room is required. While the front seats are fixed, the RD-X’s instruments, steering wheel and foot pedals can be adjusted forward and back to comfortably accommodate drivers of different statures.

A heads-up display projects pertinent information such as speed, fuel level, and other warning lights onto the windshield within the peripheral view of the driver allowing the driver to keep his eyes focused on the road. This display is shared with the Acura Satellite-Linked Navigation System, which provides mapping coverage of the entire United States and stores information on more than 3.7 million points of interest. Instead of side view mirrors, the RD-X employs two rear-facing cameras located on the front fenders. These cameras transmit a clear view of rearward traffic on both sides of the vehicle to displays mounted on the steering column.

To enable quick and easy loading of large gear, such as bicycles, kayaks or snowboards, the RD-X has unique doors on the side and in the rear. Since it does not have a B-pillar, the RD-X’s "wide open" side doors can open outward from the center to provide the largest possible opening into the vehicle.

In the rear, instead of the upward swinging hatch featured on most SUVs, the RD-X boasts two powered doors that slide open to the sides and hug the flank of the vehicle to allow easy access to the rear cargo area, even in tight quarters. These doors combine with a low, flat floor to facilitate extremely easy loading and unloading of gear that might otherwise be unwieldy in cramped urban situations.
