THE driving experience is one to behold, dominated by the effortless, torque-rich engine and ably supported by a wonderful chassis. The brakes are nothing short of superb, the four-piston calipers generating a stopping force about four times as powerful as the 911's engine. Interior space for the front seat occupants is now plentiful. It's still a 911 in its appearance, certainly the most modern and arguably the most appealing.
