2002 Acura RD-X Concept

The RD-X is designed to be powered by a unique 250 horsepower, 4-wheel drive, hybrid powertrain that combines a high-output i-VTEC(TM) engine with an Integrated Motor Assist (IMA) system. Under the hood is a high performance 2.4-liter, 16-valve, DOHC 4-cylinder engine coupled to 6-speed, close-ratio clutchless manual transmission, which drives the front wheels, while the advanced IMA system powers the rear wheels.

Inspired by Honda’s Formula One race cars, the RD-X’s clutchless manual transmission uses computer controls to operate the clutch for smooth engagement. Shifting is accomplished with a paddle shifter mounted close at hand on the center console while the close-ratio design of the gearbox helps the driver extract maximum performance from the engine.

To boost acceleration and enhance handling, especially in foul weather, the RD-X boasts a newly developed IMA system with twin electric motors to power the rear wheels when extra driving force or traction is needed. This unique configuration increases power and distributes torque similar to an all-wheel drive SUV.
