Fact file: Chevrolet Miray roadster concept
Miray concept offers glimpse into future
- Aerodynamic, sharply tapered exterior
- "Mid-electric" propulsion system for nimble, emission-free urban driving
- Sporty passenger cabin with Chevrolet dual-cockpit
The Miray roadster concept blends iconic Chevrolet design cues with more radical features and is powered by a hybrid propulsion system designed to maximize performance and fuel efficiency.
The Miray was first unveiled on March 31 at the 2011 Seoul Motor Show, in celebration of Chevrolet's 100-year heritage of designing outstanding vehicles in the brand's newest market. It celebrated its European premiere at the 2001 Frankfurt Motor Show.
"'Miray' is Korean for 'future.' As GM rolls out Chevrolet across Korea, the Miray 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", said GM Korea President and CEO Mike Arcamone, commenting on the connotation of the vehicle's nameplate.
Two front-mounted 15-kW electric motors enable swift, emission-free acceleration and ride in an urban environment. They are powered by a 1.6-kWh lithium-ion battery which is charged through regenerative braking energy. The third component of the “mid-electric” propulsion system is the Miray's 1.5-liter four cylinder turbocharged engine that kicks in with the electric motors for performance driving.
The 1.5-liter engine drives the rear wheels and the Miray can be switched from front-wheel to rear-wheel drive. Thanks to a dual-clutch transmission, the powertrain is smaller in size and comes without a torque converter. The dual-clutch transmission works in conjunction the start-stop system.
The Miray features an aerodynamic shape with expressive design cues that evoke modern jet fighters. From above, its cabin looks like a diamond. Being small and open like the 1963 Monza SS, and light and purposeful like the 1962 Corvair Super Spyder, it sports a wedged, sharply tapered body side made of carbon fiber reinforced plastic which is divided by an angled character line. Ambient lighting underneath creates a sweeping line of light when the car is in motion.
The 20-inch front and 21-inch rear wheels are made of a composite material aluminum and carbon fiber. The turbine-shape spoke design suggests movement even when the Miray is stationary.
Another dramatic design cue is apparent in the racer-style scissor doors while the dual-port grille is flanked by LED headlamps with new daytime running lamps. The front and rear fenders, meanwhile, underlines the Miray's sporty nature, emulating designs seen in Chevrolet Corvettes of the past. Spoilers made from carbon fiber as well as retractable flaps enhance airflow and help control downforce.
A carbon fiber shell that surrounds the interior provides the passenger cabin with a lightweight yet rigid structure. A mixture of brushed aluminum, natural leather, white fabric and liquid metal accentuates the feeling of velocity expressed by the Miray. The curved twin cockpit acknowledges Chevrolet's achievement in the domain of iconic and sports cars, wrapping around both the driver and the front-seat passenger.
Information is displayed via back projection to the driver and appears into three main areas – vehicle performance right in the centre, range on the left and navigation and mileage data can on the right. Ambient lighting, which starts from the upper instrument panel and flows into the seat back area, adds an air of luxury to the interior.
Rearview mirrors have been replaced by retractable rearview cameras which extend from the side glass electrically. In the city, the forward-facing camera operates in conjunction with GPS to overlay navigation information with real-time video.
