New Concept Car: Mitsubishi PX-MiEV


With the 2009 Tokyo Motor Show less than a month away, the few remaining participating automakers are throwing down their cars. Following Subaru and Honda to the table is Mitsubishi with a new plug-in hybrid crossover called the PX-MiEV and a cargo van version of the i-MiEV electric car.

Looking something like an updated Endeavour with a touch of Land Rover styling, the PX-MiEV is Mitsubishi's centerpiece. Though it may look something like the Endeavour, the PX-MiEV -- which stands for Plug-in hybrid Crossover - Mitsubishi innovative Electric Vehicle -- is actually closer in size to the Outlander but slightly larger. While the hard, boxy yet simple styling is a big step forward for Mitsubishi crossovers, the real story is what lies beneath.

The PX-MiEV is powered by Mitsubishi's first hybrid drivetrain and rather than follow the Toyota and Honda route, Mitsubishi has skipped ahead to a plug-in series hybrid right out of the gate. Under the hood is a 114-hp 1.6L DOHC MIVEC four-cylinder engine with 92 lb-ft of torque that can either power the wheels directly or act as a generator to power the electric motors. The two 60-hp electric motors generating 148 lb-ft of torque each are mounted on the axles and can propel the car by themselves or work in concert with the gasoline engine. Mitsubishi says the combination is good for an impressive 118 mpg.

At low to medium speeds, the front electric motor does most of the work by powering the front wheels. At higher speeds or when more power is needed, the gasoline engine kicks on to either make more electricity to power the electric motors or to help power the wheels directly, depending on which the onboard computer thinks will be more efficient. The rear electric motor only comes on when the front wheels are slipping, under hard acceleration or under sudden maneuvers to help stabilize the vehicle. The electric motors also act as generators during braking to recharge the battery.
