In 2004, Porsche launched a new generation of its well-known Porsche 911. That generation was named 997 and it represented an important upgrade for the whole range, especially after the 2008 facelift. After four years into production, a mid-life cycle refresh was ready for the market. Porsche had to improve its engines to make them cleaner and to respect the new pollution norms in Europe. It meant that it had to build its cars more fuel-efficient. As usual, the rest of the car suffered some minor changes too. On the outside, the first difference was on the front bumper, where larger air-intakes were sculptured. The headlights were fitted with bi-xenon lamps while the running lights and taillights were fitted with LEDs as standard. The door mirrors were slightly redesigned. A new set of 18” light-alloy wheels was introduced for the Carrera 4. As usual, both versions S and 4S featured wider rear fenders. Inside the car, on the center console, Porsche installed a new infotainment unit that featured a 6.5” touch-screen display. It featured an optional hard-drive navigation system and Bluetooth connectivity. An option for ventilated seats was added to the list. The biggest change for the 2008 Carrera 4 was underneath the car. The Carrera 4 Cabriolet featured a 3.6-liter engine that cranked up 325 hp, 30 hp less than its 4S sibling, which had a 3.8-liter unit. A new, PDK 7-speed dual-clutch gearbox was installed on the car, replacing the older 6-speed automatic. For the braking system, the Carrera 4 was fitted with 330 mm (12.99”) discs in all corners.
