Bentley Hybrid ConceptFrom its more mainstream, popular origins in the original Honda Insight and Toyota Prius, the hybrid powertrain has worked its way up to the the corner office, the big chair, the top slot in the corporation. Bentley has announced that it will introduce a plug-in hybrid option on its SUV due in 2017. Before then, we'll see what an electrically assisted Bentley looks like at the Beijing Motor Show when the Crewe automaker shows off a copper-accented Mulsanne that's been reworked into its Hybrid Concept, pictured above.

We don't have any official specs just yet, the only major announcement being that any Bentley hybrid will be able to travel at least 50 kilometers (31 miles) on pure electric thrust and get a power boost of "up to" 25 percent from its electric side. We use the phrase "any Bentley hybrid" because the company's CEO says "we will gradually introduce this powertrain across our model range" to 90 percent of the brand's lineup.

We'll know more when the Beijing show commences.
