Bentley->ke15's next addition to its lineup is a production version for the EXP 9 F SUV, but in the long-term, the company could also develop a four-door coupe model as a competitor for top versions variants of the BMW 6-Series GranCoupe and Mercedes CLS->ke539.

In a recent interview, Bentley CEO Wolfgang Schreiber said that the company would really enjoy developing such a model, but it won't happen "any time soon, that's for sure, but maybe in the longer term." According to Schreiber, such a model would sit below the current Mulsanne->ke3495 and would be just one of the models needed by the company to raise sales from 8,510 units in 2012 to 15,000 by 2018. The future four-door coupe, if produced, would be priced at about £130,000 ($198,000 at the current exchange rates).

In the same interview, Schreiber confirmed that the SUV will arrive on the market by 2015 at a starting price of £120,000 ($182,000). It will be completely redesigned from the EXP 9 F concept and Bentley has already received 2,000 orders for it.
