Acura's newest concept vehicle, the DN-X sports sedan, combines the style, handling and exhilarating performance of a high-powered sports car with the roominess and functionality of a luxury sedan.

"Don't let the four doors fool you, the DN-X concept is all sports car," Tom Elliott, executive vice president of American Honda Motor Co., Inc, said in a statement. "Looking into the future, our designers created the perfect solution for those that want a sports car but also need to carry passengers."

The mid-engine, all-wheel-drive DN-X concept is equipped with a unique 400 horsepower hybrid powertrain that combines a high-output, 3.5-litre, DOHC, i-VTEC V-6 engine powering the rear wheels and an advanced electric Integrated Motor Assist (IMA) system that provides additional power to all four wheels. Not only does this system provide outstanding performance, according to Acura, but it also achieves a fuel economy of 5.6 litres per 100 kilometres (42 miles per gallon).

During acceleration, the IMA system contributes supplemental torque, resulting in both lower fuel consumption and powerful acceleration. The IMA's ultracapacitor is recharged by regenerative braking that takes energy from forward momentum and captures it during braking. This system makes an external electric power supply unnecessary.

Mated to this high output powerplant is a unique six-speed transmission allowing the driver to chose either manual or automatic mode at his or her discretion. When placed in manual mode, the DN-X operates as a clutchless, six-speed manual transmission similar to those found in Formula One race cars. Shifting gears is accomplished using controls located on the steering wheel. Or, if desired, the DN-X can be driven as an automatic by selecting "D" on the centre console.

Also unique to the DN-X are new drive-by-wire systems that control throttle, brake and steering operations and eliminate the need for a mechanical connection between the cockpit and these components.

Designed as a "true" sports car, the DN-X has been given a highly rigid, lightweight state of-the-art chassis tuned to provide the ultimate in handling and maximum aerodynamic efficiency. Fully independent front and rear double wishbone suspension, large ventilated disc brakes, 18-inch alloy wheels in front and 19-inch alloy wheels in the rear complement the DN-X's sporty personality.

The DN-X is equipped with a host of technological innovations. Among them is the Intelligent Driver Support system (IDS) which is comprised of Lane Keeping Assistance and Adaptive Cruise Control.

Lane Keeping Assistance uses CCD cameras to recognize when the DN-X is veering out of its lane. On a highway, these cameras detect the lane markings and, if the car veers out of its lane, an audible and visual warning occurs and the steering automatically re-centers the car in its lane. The Adaptive Cruise Control system uses sensors to keep the DN-X a safe distance from the car in front of it by controlling the accelerator and brake as needed. Laser radar tracks the speed and distance of the vehicle in front and maintains the DN-X's speed accordingly.

Another component of the DN-X's high-tech wizardry is the Night Vision System. Night Vision uses infrared cameras to enhance visibility and safety at night. Active Headlights further aid visibility by adjusting the angle of its beams to match the speed and direction in which the vehicle is travelling.

Inside, the instrument panel of the DN-X, featuring interactive voice-recognition, is divided into three, easy-to-read units. A pop-up display in the centre console provides access to e-mail, Internet and cellular telephone service. The LCD screen also shows navigation information from the Acura Satellite-Linked Navigation System.

Housed in the centre display is a navigation section that indicates upcoming turns as well as the presence of objects in the roadway detected by the vehicle's Night Vision System.

The third unit is comprised of a three-dimensional meter located in the dashboard that displays the speedometer, tachometer and odometer. In addition, alerts from the IDS system, notification of incoming phone calls and e-mails, as well as other basic driving status information are also displayed on this meter.

"The DN-X concept illustrates our vision that driving enthusiasts don't have to compromise the performance and styling they want for the functionality they may need," said Elliott. "This super sedan really combines the best of both worlds."
