Bentley Bentayga review – the ultimate luxury SUV? - Engine and gearbox
Bentley's first SUV is sure to be a sales hit, but its sheer weight limits the appeal as a drivers SUV
Engine and gearbox
There are only two engine choices in the Bentley Bentayga for now – a 6.0-litre W12 petrol engine or a 4.0-litre V8 diesel. We may see a smaller, V8 petrol in the future, as in the Continental, which could become the engine of choice.
No matter which unit you go for, out-and-out muscle is the name of the game.
Both engines are mated to the same smooth ZF 8-speed gearbox, which sees service in everything from the Range Rover Sport to the BMW 1-series, so there’s no cause for concern there – it’s smooth and quick-shifting and, more importantly, can handle the 600+lb ft of torque that both engines produce.
Which engine you choose depends where your priorities lie. A diesel engine in a supposed ‘luxury’ vehicle may seem like sacrilege – and owners of the Bentayga aren’t likely to have more than a passing interest in fuel economy anyway. No, where the diesel wins out is range. It’s not very glamorous filling up at the local Esso, and stopping every 350 miles in the W12 is bound to become tiresome on a cross-continental cruise. The diesel on the other hand can manage almost 600 miles on a tank, theoretically nearly halving your fuel stops and making for a much more relaxed, and faster, journey.
