BMW's generously proportioned 5-series sedan looks destined exclusively for China. As part of the company's partnership with Brilliance China Automotive, BMW Brilliance Automotive is planning to create a pure EV 5-series and to show it off this year -- at some point. No further details are known about the car, though we're quite sure why this is happening. EVs are becoming more and more popular there as China struggles to shrug off a massive foreign oil dependency and BMW saw a similarly massive 87 percent jump in growth of its sales in China in 2010. So, there's your motive, but we'll still have to wait a bit for the rest of the details.
