Under the hood, the 964 boasted a range of powerful engines, including the 3.6-liter flat-six found in the Carrera 2 and Carrera 4 models. These engines offered impressive performance, with the 250 horsepower Carrera 2 capable of accelerating to 60 mph in under 6 seconds. The 964 was also offered in a variety of body styles, including the iconic coupe, the practical Targa, and the luxurious Cabriolet. Notably, the 964 saw the introduction of the first-ever all-wheel-drive 911, the Carrera 4, which greatly enhanced handling and traction.
