The Mi-ray features a concept “mid-electric” propulsion system, located primarily behind and beneath the driver. 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 torque control to both the left and right wheels as needed. The engine, mounted behind the cockpit, drives the rear wheels while integrating electrification technology.
A dual-clutch transmission (DCT) enables a reduction in the powertrain’s size by eliminating the torque converter. The shift pattern has been tuned for improved top speed in performance mode. A start-stop system works in conjunction with the DCT.
Made of carbon fiber and CFRP (carbon fiber-reinforced plastic), Mi-ray’s wedged body side is divided by an angled character line, with ambient lighting underneath. Le Mans racer-style scissor doors open up and out of the way.
The Mi-ray features aluminum-carbon fiber composite 20-inch wheels in front and 21-inch wheels in the rear.
