Bentley has been clever to spot a gaping hole in the SUV market above the ubiquitous Range Rover and have developed this Bentayga model to fill it. Originally launched with a huge 600PS W12 petrol engine, it's also now available in diesel form, with a petrol V8, with Plug-in hybrid power or even in wild W12 Speed guise. Either way, it can go properly off-road and packs some impressive statistics.
