I think we have a winner for the greenest car at the 2007 Tokyo Motor Show. Below the fold is a video all about the Mitsubishi iMiEV Sport concept. It's a plug-in electric car with a cool tear drop shape and a number of cool ways of charging the batteries. The iMiEV's lithium-ion batteries can be charged via a wireless microwave charger in your garage floor which means you don't have to struggle to plug it in.

Not keen on turning your garage in a giant microwave? Don't worry, the iMiEV has solar panels on the roof and micro wind turbines in the front grill. The iMiEV has other strange features like the ability to connect to your computer, in-hub motors and an electric plug that flips open. BTW I think the way you say the car's name is eye My EV, which also gives iMiEV our award for strangest car name at the 2007 Tokyo Motor Show.

The engines in sports cars aren't built for fuel efficiency or low emissions, they're built for speed and power. It's always nice when these seemingly mutually exclusive design criteria align, but typically you're not going to see too much written about sports car V8 engines on AutoblogGreen. One such engine which we'd usually spurn is the brand new V8 powerplant that BMW is shoehorning into their M3 super sedan. There was one feature of this particular engine hidden way down the bottom of the BMW press release though that caught my green eye - it features a new technology BMW are terming Brake Energy Regeneration.

Brake Energy Regeneration is an electrical current management technology that ensures intelligent generation of electric power by restricting production to the engine overrun phases and the application of the brakes. The power produced is used to run the vehicle's electrical network and charge the battery which is restricted via Brake Energy Regeneration to times when the engine will not be hampered by the additional draw upon its resources.

Analysis: Is it just me or does this sound like BMW have been toying around with hybrid regenerative braking? I'm pretty sure that if BMW thought putting electric hub motors on each wheel of their M3, M5 and M6 would increase their performance they'd do it tomorrow. Perhaps the next M-powered BMW will be a hybrid sports?

Full press release after the jump.

The new 2007 Cadillac BLS Sport model has just gone on sale in Europe to extend the BLS sedan lineup. "Sports" features include bigger 18-inch wheels, lowered sports suspension, and chassis tuning to take advantage of the powerful engines available and to give more dynamic handling performance without compromising comfort.

Engine options include two 2.0 litre turbocharged petrol engines which output 129kW / 175hp and 154kW / 210hp, while a 2.8 liter V6 unit puts out 188kW / 255hp. Also available in the Sport range is a direct-injected, common rail turbo-diesel engine fitted with a maintenance-free diesel particulate filter, developing 110kW / 150hp plus, no doubt, a mountain of torque. Transmission options are six-speed manual or an automatic with a "Sport Mode". The interior features aluminium trip instead of wood and a tweaked instrumentation panel, along with a three-spoke leather steering wheel.
