The first vehicles from BMW’s new i division for sustainability and future mobility, the i3 electric hatch and i8 plug-in hybrid sports car, are nearing the end of their development phase and will be launched on the market in 2013 and 2014, respectively. However, BMW shows no signs of slowing the rollout of its new i models and will present at next week’s 2012 Los Angeles Auto Show a concept of yet another i vehicle.

No details about the new concept have been released, though like all i vehicles it will be purpose-built from the ground up as electric or hybrid, and be constructed primarily from lightweight carbon fiber.

There have been reports claiming BMW will present an ‘i4’ sports car concept in L.A. The vehicle is said to be based on the same platform found in the i3, but modified with a wider track and sportier suspension for improved driving feel. Like the i3, the vehicle would be developed as either a pure electric or extended-range electric car.

Another possibility, though one that’s looking less and less likely, is a new ‘i5’ extended-range electric MPV designed to take on the top-selling Toyota Prius.

The good news is we don’t have too long to wait to find out; the first press days for the Los Angeles show commence November 28. In addition to the new i concept, BMW will also be presenting its previous i8 Spyder concept and X1-based K2 Powder Ride ski concept.
