Developed at the GM Advanced Design Studio in Seoul, the Chevrolet mi-Ray Concept combines a hybrid powertrain with an advanced design and technologies that explore future possibilities for the brand.


Presented at the 2011 Seoul Motor Show, the Chevrolet Mi-ray Roadster Concept celebrates the brand’s 100th anniversary and its market launch in Korea – the name Mi-ray is Korean for future.

Chevrolet Mi-ray Roadster ConceptThe 2-seater has compact dimensions (just 3.9 meters in length) and the classic proportions of mid-engine sportscars, reinterpreted using a hi-tech, elaborated surface treatment, with an interplay of sharp edges and wedged, sculptured surfaces.

The body, made of carbon fiber and CFRP (carbon fiber-reinforced plastic), is visually split in two parts by an angled character line, further underlined by the presence of underneath ambient lighting.

Additional highlights are the dual port grille of front end, scissor doors, retractable rearview cameras and retractable flaps that provide airflow control.

The interior continues the aeronautic theme with a twin cockpit that wraps around the driver and passenger.

Among the features are the asymmetric seats, with the headrests following the exterior surfaces and integrating an air scarf for open-air driving.

The dashboard is driver-focused and uses back projection on the instrument panel.

The hybrid powertrain features a 1.5-liter four-cylinder turbocharged engine located behind the cockpit, complemented by two front-mounted 15-kW electric motors.

The system is coupled with a dual-clutch transmission (DCT) and offers the driver the possibility of switching between front-wheel drive and rear-wheel drive.

Additional detail can be found in the official press release, reported below.

From the official Press Release:

Exterior Design

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.

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 powerful front end offers 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 tail-lamps 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.

Interior Design

The interior of the Mi-ray echoes Chevrolet’s racing heritage. As with the exterior, it takes inspiration from jet fighters. The Mi-ray contains a melange of brushed aluminum, natural leather, white fabric and liquid metal surfaces, for an overall effect of sculptural velocity.

The interior compartment is surrounded by a carbon fiber shell, which gives it a lightweight yet rigid structure. Its flowing, yet slightly tensioned, twin cockpit tightly wraps around the driver and passenger.

The cockpit is driver focused, drawing inspiration from the iconic Chevrolet sports car. However, the passenger is also fully engaged in the driving experience.

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.

Technical Features

The Mi-ray features a concept “mid-electric” propulsion system, located primarily behind and beneath the driver, that maximizes performance and fuel efficiency.

“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.
