For people who have always wanted to see the the much-anticipated BMW i8 Concept Roadster, BMW will soon grant your wish.

BMW has announced that the North American debut of its concept, open-top supercar will occur at the 2012 Los Angeles Auto Show->ke211, which opens its doors to the public next week. This debut will allow people to actually enjoy the design in person and will also give us some insight on the future design language that the Bavarian giant will employ.

It's not only the design that will impress, but the theoretical performance of the concept is also to be admired. Powered by a frugal 3-cylinder gasoline engine that produces 134 horsepower and an electric motor that produces 220 horsepower, the total output of the powertrain comes close to 354 horsepower. With its modular carbon-fiber construction and 50-50 weight distribution, this hybrid powertrain propels the car from 0 to 60 mph in 4.9 seconds and to a limited top speed of 155 mph.

With hybrid technology being this concept's key selling point, you likely expect exceptional fuel economy. Well, the i8 definitely doesn't disappoint in that aspect, as it features an impressive 78 mpg.

The i8 Roadster will be launched for sale sometime in 2014 and is expected to cost about $130,000. If this is true, then roadster enthusiasts, start saving up because this Bimmer->ke178 is truly a keeper.
