With the new Bentley Bentayga Speed V-8, the W-12 is outperformed

Nearly a year has passed since Bentley produced its final W-12 engine, ending over two decades of twelve-cylinder power. Though the iconic powerhouse has been retired, Bentley insists its replacement offers a superior experience—an expected claim, of course. The latest Bentayga Speed trades in the previous 6.0-liter W-12 for a smaller 4.0-liter twin-turbocharged V8. Despite the downsizing, performance hasn’t suffered. In fact, the new engine produces 641 horsepower, a modest increase of 15 hp over its predecessor. However, torque sees a slight drop to 627 lb-ft, down 37 lb-ft from the outgoing unit.

While it may not top the performance charts alongside rivals like the Aston Martin DBX S, Ferrari Purosangue, Dodge Durango SRT Hellcat, Lamborghini Urus SE, or Porsche Cayenne Turbo E-Hybrid—all of which exceed 700 hp—it still delivers serious performance. The reduction in engine size has also trimmed the SUV’s weight by around 95 pounds, bringing the total to 5,435 pounds. This lighter arrangement enhances acceleration, reducing the duration from 0 to 62 mph to 3.4 seconds, which is half a second faster than previously.

Top speed now reaches 193 mph, slightly faster than the previous model. Handling also improves, with the addition of rear-wheel steering, making the huge SUV seem more agile. For those seeking even more stopping power, carbon-ceramic brakes are available, though only when equipped with the large 23-inch Speed wheels. Bentley has also fine-tuned the Sport mode by stiffening suspension dampers by 15% over the Bentayga V8 S and sharpening steering feedback for a more connected driving feel.

As for sound, the V8 comes with a standard sports exhaust to compensate for the loss of the W-12’s distinctive growl. Enthusiasts can also opt for a more aggressive Akrapovič titanium exhaust featuring quad tips. Styling updates remain subtle, with darkened headlights and taillights, optional black roofs in satin or gloss, and revised seat designs and upholstery choices. Interior chrome details can also be swapped for darker finishes to elevate the sporty aesthetic.

Even if the W-12 is no longer available, Bentley assures drivers that the brand’s spirit is still intact. The shift reflects growing emissions regulations, which have already led most of Bentley’s lineup to adopt hybrid powertrains. The Bentayga stands as the last purely combustion-powered model in the range. Bentley’s next significant release will be its first entirely electric vehicle, a smaller SUV that reflects the company’s changing direction.
