Bentley plug-in hybrid concept promises 50km on electricity only

Bentley is set to show off its hybrid car concept at the Beijing International Automotive Exhibition on April 20. The hybrid vehicle that will on display at the show is based on the Mulsanne, which is the top of the line vehicle that Bentley produces. Bentley won’t be offering the Mulsanne in a hybrid version anytime soon. It's simply the test bed for showing off the plug-in hybrid technology.
