Prototype and production hybrids and electric cars debuted this week at the International Motor Show in Frankfurt, Germany. Car manufacturers showed off sportier designs—and some outlandish models.
The i8, shown here, is BMW’s first plug-in hybrid sports car. It can reach 62 miles per hour in 4.6 seconds, has a top speed of 155 mph, and can achieve 87 miles per gallon. It weighs 3,200 pounds. A version of the car will probably be on sale by the end of 2013.
