The Porsche 911-997 generation was introduced in 2005 and it was more of an evolution rather than a revolution. But in terms of design, it was much better, even if that meant to return to the round headlights. The 997 Carrera 4 was based on the same platform with its predecessor but enhanced. It had the same rear wide fenders as the Carrera 4S and the Carrera S and it offered an enhanced all-wheel-drive system, which transferred between 5 and 40% of the torque to the front wheels. From the outside, the new round headlights were back, wiping off the tears from the Porsche fans. The turn-signals and the fog-lights were in the front bumper, above the apron. In the lower side, a wide center grille and two side-scoops with a horizontal slat were typical for this generation of the Porsche 911. Inside, the 911 offered four seats but cramped in the rear. It offered four seating options: standard, electric, sport, and adaptive bucket-seats. For the instrument cluster, the Carrera 4 featured the classic five-dials layout, with a black background. The Porsche Communication Management was fitted as standard, but the navigation system was optional. For the engine, the Carrera 4 offered a 3.6-liter engine that offered 325 hp. It was mated as standard with a 6-speed manual, while a 5-speed automatic with manual override (Tiptronic) was on the options list.
