The Bentayga is fully capable of being obnoxious. The all-new 6.0-liter W-12 grunts out 600 horsepower at 6000 rpm and 664 lb-ft of torque from 1350 to 4500 and will whip this horse to 60 mph in a claimed four seconds flat. That’s sure to widen the eyes of occupants and bystanders alike.
The new W-12 shares its bore spacing with its predecessor but no parts. Bentley shaved 66 pounds from this generation, an impressive feat with such a dense box of mechanical parts. Engineers pulled precious ounces from everything—the block, heads, crank, and cams to name just a few. The one system that isn’t lighter is the fuel injection, which now has direct and port injectors. At idle and under full load, the direct injectors do their precise work, while the port injectors are engaged at part throttle, when they’re said to better mix fuel and air while reducing emissions. Bentley also claims the W-12 is 10 percent more efficient than its predecessor, with cylinder deactivation shutting down six cylinders when conditions are right and a “sail mode” that decouples the engine from the transmission when the driver is off the throttle at higher speeds.
