BMW i3 and i8 (1)

BMW  just raised the stakes for electric vehicles by unveiling its new  i Series concept cars. The runabout all-electric i3 is to debut in 2013, followed by the sporty i8 hybrid in 2014.

Both  4-seaters push the boundaries of design and technology with advanced drivetrains  and breakthrough carbon fiber bodies that shave weight to improve performance  and mileage.

The more conventional i8 will have a 3.0 liter six-cylinder engine with a  parallel electric motor to provide 349 horsepower. Using lightweight carbon  fiber, the reduced weight allows the car to reach 60mph in a numbing 4.6 second.

The i3 is even more unique. Built on an all-electric powertrain for an urban  environment, the car can go 98 miles with full batteries, and can charge up 80%  in an hour.
