Last year, Tesla Motors' Roadster was all the rage. The Lotus-inspired, all-electric sports car delivers 244 miles on one charge, and retails for about $110,000. Although it was never meant to be a vehicle for the average consumer, the rich and eccentric took to it, boasting a high-end sports car (0 to 60 in 3.9 seconds) with the added benefits of serious green credentials.

Of course, the roadster wasn't just a one-time deal for Tesla. Today, the progressive car manufacturer is coming to the table with a new Sedan. This vehicle can deliver 300 miles on one charge, carry seven people, and goes for about half the price of the two-seater roadster. Certainly not a cheap car by any stretch of the imagination. But at about $50,000, also not completely out of reach for those who would typically plunk down roughly the same amount for a Lexus or BMW 5 Series.

Tesla will be opening a second store in Chicago this spring, and plans to open 6 more stores in London, New York, Miami, Seattle, Munich, and Washington D.C.

Chinese electric car manufacturer, BYD also made news this week after announcing that it had accepted Warren Buffet's invitation to display its electric cars at a general meeting of shareholders in Omaha.

BYD started selling its first mass-produced plug-in hybrid last December in China. This particular model, the F3DM, delivers 62 miles on one charge, and carries a price tag of around $22,000.

Warren Buffet bought a 10 percent stake in BYD last September.
