Chevrolet introduces Mi-ray concept in Seoul

(March 31, 2011) SEOUL — Chevrolet introduced the 'mid-electric' hybrid Mi-ray concept today at the 2011 Seoul Motor Show. The roadster celebrates Chevrolet’s 100-year heritage of designing expressive vehicles in the brand’s newest market.

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.”

The Mi-ray was developed at the GM Advanced Design Studio in Seoul. Combining cutting-edge hybrid propulsion technology and advanced styling, it balances iconic Chevrolet design cues with a future design vision as Chevrolet celebrates its centennial in 2011.

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.

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.

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.

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.
