The Bentley EXP 9 F concept, unveiled at the Geneva motor show, shows how a 180mph, £150,000 Bentley SUV would look in production. The concept, powered by a re-engineered version of the current 6.0-litre petrol W12 engine, is as long and slightly lower than a Range Rover, but much more powerful. A W12 petrol version will be the production flagship, but Bentley will also offer buyers the choice of a V8 diesel engine or a V6-based plug-in hybrid powertrain.
