The Bentley Bentayga loses its signature W12 engine for 2025. That means the only engine left is a twin-turbo 4.0-litre V8 producing 542 horsepower, which is still ample enough to motivate this large and heavy luxury SUV. The British automaker has another option under the hood, mind you: a plug-in hybrid powertrain combining a 3.0-litre V6 with an electric motor and 18.9kWh battery and enabling up to 34 km of pure electric range.
