The engine delivers its peak torque from as low as 1750 rpm, yet we felt a notable surge in thrust above 3000 rpm. The exhaust note is normally a muted growl, but there’s a pronounced (and deliberate) burble on the overrun. The transmission is superb, whether one opts to use it in automatic or manual mode, with precise, beautifully smooth shifts.
Perhaps the most impressive feature of the GTC Speed is the solidity of the convertible shell. Brian Gush, Bentley’s director of chassis, powertrain, and motorsports, says this allows the automaker to fit relatively soft springs. The ride, considering that the car rolls on 20-inch tires, is remarkably supple in the adjustable suspension’s more-comfort-oriented settings. Body control in the most sporting tuning is pretty impressive, too. The car drives smaller than it is, always a reflection of a well-developed chassis. The steering is the only dynamic flaw, being a little numb and relaying little feedback to the driver.
