Bentley EXP 9 F SUV concept

The Bentley EXP 9 F concept, unveiled at the Geneva motor show shows how a 290kph Bentley SUV would look in production.

The concept, powered by a re-engineered version of the current 6.0-litre petrol W12 engine, will be as long and slightly lower than a Range Rover, but much more powerful. The W12 petrol version will be the flagship, but Bentley will also offer buyers the choice of a V8 diesel engine or a V6-based plug-in hybrid powertrain.

“We are aiming for the very top of the pinnacle with this model,” says Bentley CEO Wolfgang Duerheimer. “We want it to be the most prestigious, fastest and the most expensive SUV money can buy. We will position it well above the Range Rover, Porsche Cayenne Turbo S and Audi Q7, the most expensive European SUVs at present.”

Duerheimer sees great potential for the Bentley EXP 9 F in emerging markets like China and Russia, but points out that Bentley’s biggest market continues to be the USA, home of the full-size SUV.

The EXP 9 F, which will have a proper name Bentley insiders “already know and are investigating”, will probably become the marque’s best-selling model, with initial production around 3500 units rising to 5000 as markets develop. Last year, the Bentley Mulsanne and Continental, sold a total of 7000 units. Any foreseeable production rise can be handled comfortably without any major expansion of Crewe’s relatively modern plant, says Duerheimer.

The EXP 9 F project is very much the brainchild of Wolfgang Durheimer, who pushed the Porsche Cayenne SUV through against entrenched opposition from colleagues, dealers and 911 enthusiasts while he was product chief in Zuffenhausen a decade ago. It has since become easily Porsche’s best-selling model.

However, Duerheimer is careful to point out that the Bentley SUV project has yet to win full board approval, though he makes no effort to disguise his enthusiasm for it. He sees it as a vital step in helping Bentley earn sustainable profits, a status it needs to fund future models. The company has just announced a 40 percent sales jump, and is believed to have operated profitably in 2011.

Work on the concept began last July in the Crewe design department. A three-week sketching phase led to the creation of four one-third scale models. From these, two were chosen and used to create a pair of full-size models.

The EXP 9 F, which van Braeckel admits is close in size and proportions to the way a production model, is almost identical in length to the Range Rover at five metres, but its wheelbase is 200mm longer (and 150mm longer than the Cayenne) reflecting the emphasis Bentley puts on creating a roomy rear compartment for a model will often be chauffeur-driven. The Bentley also sits between Range Rover and Cayenne for roof height and body width. Its driver sits 100mm higher than in a Porsche, but 30mm lower than in a Range Rover’s.

Bentley’s designers are especially proud of the EXP 9 F interior, which they believe is more luxurious and stylish, with better quality wood and leather and more equipment than any existing SUV. The interior will be familiar to Bentley owners, thanks to the bullseye vents and organ-stops.

According to Duerheimer, Crewe will become the development home for all VW Group 12-cylinder engines, and will probably manufacture them for the group, too. The W12 remains the chosen layout (engineers cite its compactness as a major advantage for an SUV) but a re-engineered version, due before the SUV’s launch date, will get many upgrades including direct fuel injection, cylinder deactivation and friction reduction, designed to improve fuel consumption and cut CO2.
