Bentley has unveiled its first ever SUV - the Bentayga. Described as the most powerful SUV in the world, the Bentayga's 6.0-litre turbocharged engine is mated to an eight-speed automatic gearbox, for a 0-62 time of 4.1 seconds and top speed of 187 mph. An integrated skid plate in the lower front bumper, along with muscular haunches and large, 22-inch alloy wheels, hint at the cars off-road capabilities while up to eight drive settings help with variable rugged terrain. The Bentayga will be debut at the Frankfurt Motor Show.
