The 2013 BMW i3 and i8 concepts

The 2013 BMW unveils new i3 and revamped i8 concepts. BMW's been teasing us with its vision for electric motoroing for years, and today, folks, the trend continues. The German automaker has unveiled two concepts from its upcoming i sub-brand: the city-dwelling i3 and a rehashed version of its i8.

This is the first time we've officially seen the smaller of the two, as the car formerly known as the Megacity had only been spied in an official render and during routine testing at the arctic circle. 

It'll haul four peeps with its 150km range (around 100 miles) and accelerate from 0-60mph in around 8 seconds. As for those with range anxiety, the German company will soothe such fears with an optional range-extending motor dubbed "REx."

Either variant could land in your garage in 2013, where you'll be able top them up in 6 hours with a standard socket, or up to eighty percent in an hour if you're rocking a spiffy high capacity charger.  The i8, which you'll recall for its radical aerodynamic design and hybrid diesel-electric drivetrain, has received a bevy of aerodynamic tweaks and junked its oil burner, opting for a gasoline one instead.

Engine swap aside, the sporty coupé apparently drinks only 2.7 liters per 100km -- 87 mpg (!) for yanks -- which is unreal in a car that'll accelerate to 62mph in 4.6 seconds. Sound too good to be true? We'll have to wait until 2014 to see if München can make good on those promises, but in the meantime feel free to peruse the galleries, videos, and PR after the break.
