|The Concept-CT in-wheel series/parallel hybrid|
As promised, Mitsubishi Motors North America (MMNA) unveiled the Concept-CT in-wheel gasoline-electric series/parallel hybrid (earlier post) at the Detroit auto show.
The Concept-CT is electric-dominant, obtaining the majority of its drive torque via the electric in-wheel motors, which are powered by a 1.0-liter genset and Li-ion batteries in a conventional series-hybrid configuration. At constant speed, however, the Concept-CT can add engine-powered rear-wheel drive for extra driveability (the parallel-hybrid aspect).

The foundation of the Concept-CT is the Mitsubishi In-wheel Electric Vehicle (MIEV) hybrid powertrain, which employs an electric motor in each of the vehicle’s four wheels. (Earlier post.) Mitsubishi proposes to use MIEV as the core drive element in full-electric, hybrid-electric and fuel-cell applications.
The Concept-CT is based on the i minicar platform (earlier post), although the engine in the CT is a larger, specially-designed 1.0-liter, 3-cylinder 50-kW (67-hp) gasoline engine. The rear-mounted engine (just forward of the rear axle) drives the 40-kW generator, and also provides rear-wheel drive under certain conditions.
The generator charges a lithium-ion battery pack. The in-wheel motors each deliver 20 kW. Total combined peak power (in-wheel motors plus engine) is 100 kW (134 hp).
