Porsche

The all-wheel-drive versions of the 911 Carrera are nearly two inches than their two-wheel-drive counterparts. This extra width is needed to cover the wheels that are part of the enhanced all-wheel drive system.

With its 325-horsepower 3.6-liter horizontally opposed six-cylinder engine, the 911 Carrera 4 is capable of accelerating from a standing start to 60 mph in just 4.9 seconds. When equipped with the optional Tiptronic S automatic transmission, the 911 Carrera 4 Coupe accelerates to 60 mph in 5.3 seconds.

The 911 Carrera and Carrera S Cabriolets were designed and developed in parallel with the fixed-roof sports cars. Instead of merely taking a Coupe, cutting off its top and then reinforcing its structure with weighty panels, Porsche engineers were able to provide the pleasures of open-top motoring by designing a vehicle that offers the stiffness and strength without unwanted weight. The result is outstanding dynamic performance with exceptional safety protection.
