Bentley's upcoming electric car debut won't be an SUV or a sports car, as previously glimpsed with the company's EXP 12 Speed 6e concept.

Speaking with British magazine Auto Express, Bentley's design director Stefan Sielaff has questioned whether putting the concept sports car into production would be a good idea.

'It should be a four- or five-seater and it should also have the possibility to carry a little bit of luggage, maybe not for five people,' said Sielaff. 'I think we need to make sure that this family member is obviously new, and not imitating another concept we have already in the portfolio. But definitely more than two seats; that’s something I am convinced of.'

'We are still in the phase of trying to define what it could be but nevertheless, I think it should be a vehicle that contains a certain coupe-style or sportivity, and also a certain elegance,' he added. 'I don’t think it should be something that is raised high, like an SUV.'

The car will be based on the same platform as the production version of Porsche's Mission E concept rather than anything else in Bentley's current product lineup

'The next step for sure is an electric, unique Bentley that isn’t based on an existing car but a completely fresh and new development, with electric propulsion and obviously different proportions following the function,' Sielaff said. 'It gives us a great chance to establish a completely new design language for the company.'

One possibility for the electric Bentley could be a four-door coupe, much like the concept Mission E, which would present a whole new territory for the company.
