The Mitsubishi ESR (Ecological Science Research) is a hybrid electric vehicle (HEV) concept exhibited by Mitsubishi Motors at the 30th Tokyo Motor Show in 1993.[1] It was designed to demonstrate the company's technological developments in alternative energy,[2] and used a 70 kW AC induction motor to drive the front wheels. 28 alkaline batteries housed under the passenger compartment, and a rear-mounted 1.5 L gasoline engine powered an on-board electrical generator system.[1] It also recycled its own kinetic energy, and absorbed solar power through roof-mounted cells.[2]
The car was estimated to have a range of 620 miles (998 km) on hybrid power at a constant 25 mph (40 km/h), or 310 miles (499 km) using only the batteries. A Global Positioning System (GPS) receiver could automatically switch the vehicle from hybrid to battery-only operation when entering an urban areas.[3] Mitsubishi claimed a maximum speed of 200 kilometres per hour, thanks in part to a drag coefficient of 0.25.[4]
