Chevrolet Celebrates Centennial in Newest Market
Chevrolet?s global presence was illustrated when they debuted the Mi-ray roadster concept at the Seoul Motor Show in March.? Developed at the GM Advanced Design Studio in Seoul, Mi-ray combines cutting-edge hybrid propulsion technology and advanced styling with iconic Chevrolet design cues.
Celebrating Chevy?s 100-year history, the Mi-ray pays tribute to Chevrolet?s sports car heritage. It is small and open like the 1963 Monza SS, and light and purposeful like the 1962 Corvair Super Spyder. Its aerodynamic fuselage is reminiscent of modern jet fighters.
According to GM Korea President and CEO Mike Arcamone, ??Mi-ray? is Korean for ?future.? As GM rolls out Chevrolet across Korea, the Mi-ray concept offers an exploration of future possibilities for the brand. It strengthens the bond between car and driver, creating a fresh look at what sports cars of the future might be.?
Made of carbon fiber and CFRP (carbon fiber-reinforced plastic), the wedged body side is divided by an angled character line, with ambient lighting underneath. This accent creates a sweeping line of light when the car is in motion, bringing a warm glow to the sculptured body. Le Mans racer-style scissor doors open up and out of the way for dramatic access to the interior.
The front end displays a reinterpretation of the Chevrolet face. The Mi-ray?s dual port grille is flanked by LED headlamps with new signature daytime running lamps. The front and rear fenders evoke Chevrolet Corvettes of the past and express the concept?s sports car spirit. At the corners, carbon-fiber spoilers help control down force and airflow.
Distinctive retractable flaps provide additional airflow control while providing access to the charge port on one side and the fuel filler on the other. The charge port also features an external battery charge indicator. Each rear fender contains individual cargo space for the storage of small items. Under the ducktail surface, the taillamps provide a new interpretation of Chevrolet?s twin element identity.
The Mi-ray features aluminum-carbon fiber composite 20-inch wheels in front and 21-inch wheels in the rear. The strong turbine theme evokes movement, even when the Mi-ray is stationary.
The heavily tapered top view enhances the Mi-ray?s purposeful image. From above, the cabin has a unique diamond shape.
The interior is inspired by the cockpits of from jet fighters and is filled brushed aluminum, natural leather, white fabric and liquid metal surfaces. The interior compartment is surrounded by a carbon fiber shell adding to the lightweight rigid structure.
Asymmetric seats flow from the door, forming a symmetric interior that gives the driver a feeling of being fully connected with the car. Ambient lighting, which starts from the upper instrument panel and flows into the seat back area, adds a sense of luxury. Seat cushions and headrests are connected by the lightweight carbon fiber shell and mounted on a single aluminum rail. The headrest area follows the exterior form, integrating with an air scarf for open-air driving.
Designers took a unique approach to displaying information, using back projection on the instrument panel. Information in front of the driver has been prioritized into three zones. Immediately in front is vehicle performance. It is flanked on the left by range and on the right by navigation and mileage figures. This eliminates unnecessary visual clutter, allowing the driver to focus on the thrill of driving.
The center touch screen flows down to an aluminum support, which evokes a fighter jet?s nose with the landing gear down. The exterior surface waterfalls down into the interior to meet the reinforced console, connecting the front and rear of the car.
The centrally located start button is also inspired by a jet aircraft. When the button is pressed, the column-mounted retractable meter cluster rises like a jet fighter canopy and ?Interactive Projection? appears on the white surface.
Retractable rearview cameras, which replace traditional rearview mirrors, extend from the side glass electrically. In city driving, the forward-facing camera operates in conjunction with GPS to overlay navigation information with real-time video.
?Many of the components in the Mi-ray?s propulsion system are a logical extension of GM?s current technology portfolio,? said Uwe Grebe, executive director for GM Powertrain Advanced Engineering. ?The concept shows the potential for reconfiguring, rescaling and extending today?s propulsion technologies.?
The Mi-ray is propelled by two front-mounted 15-kW electric motors for quick acceleration and zero emissions in urban driving. The motors are powered by a 1.6-kWh lithium-ion battery that is charged through regenerative braking energy. The Mi-ray has the capability of being switched from front-wheel drive to rear-wheel drive.
For performance driving, the Mi-ray?s 1.5-liter four-cylinder turbocharged engine combines with the electric motors, providing spirited torque control to both the left and right wheels as needed. The high-tech engine, mounted behind the cockpit, drives the rear wheels while seamlessly integrating electrification technology that defines a new standard in the compact roadster segment.
A dual-clutch transmission (DCT) enables a reduction in the powertrain?s size by eliminating the torque converter. Shifts are quick and firm. The shift pattern has been tuned for improved top speed in performance mode. A start-stop system works in conjunction with the DCT.
?The propulsion concept fits perfectly with the rest of the vehicle, delivering big performance in a small footprint, on the road and in the environment,? said Arcamone.? ?By combining GM propulsion technology and visionary design, the Mi-ray points to the future of Chevrolets around the globe ? expressive, youthful and entertaining.?
