The wait is over for those of you wanting a 'safety net' when driving the new Porsche 911. The Carrera 4 and 4S with all-wheel drive has now been officially launched.

Porsche Centre Singapore unveiled the new 911 Carrera 4 and 911 Carrera 4S to customers and the media at the National Museum of Singapore. Also available in cabriolet form, the new all-wheel drive cars have the same lightweight body design, suspension, engines and gearboxes as the rear-driven siblings.

The easiest way to differentiate the 911 with all-wheel drive is to look at the rear wide arches. They are a total of 44 mm wider (22 mm each side) than the rear-wheel drive 911s. Each rear tyre is also 10 mm wider. There is also a sleek red light band that connects the two taillights - making it very easy to spot at night.

All four new models consume as much as 16 percent less fuel and are up to 65 kg lighter in weight compared to the outgoing model.

With a PDK gearbox as standard, the 911 Carrera 4 Coupé with 350 bhp can sprint from 0 to 100 km/h in 4.5 seconds and reach a top speed of up to 285 km/h. Fuel consumption with PDK is 8.6 l/100 km with CO2 figures at 203 g/km for the Coupé and 8.7 l/100 km and CO2 205 g/km for the Cabriolet.

The Coupé and Cabriolet of the 911 Carrera 4S each have a 3.8-litre rear-mounted boxer engine that produces 400 bhp. This enables acceleration to 100 km/h in 4.1 seconds (Cabriolet: 4.3 seconds) and a top speed of 299 km/h (Cabriolet: 296 km/h). Fuel consumption values with PDK are 9.1 l/100 km with CO2 figures at 215 g/km for the Coupé and 9.2 l/100 km and CO2 217 g/km for the Cabriolet.

In the new 911 Carrera 4, a new menu in the instrument cluster informs the driver how the PTM all-wheel drive is currently distributing engine power. In addition, with the debut of the 911 Carrera all-wheel drive models Porsche is introducing the optional Adaptive Cruise Control (ACC) to the entire model range, which controls distance to traffic ahead and vehicle speed. When ordered with PDK, the ACC system adds the safety function Porsche Active Safe (PAS), which helps to prevent front-end collisions. In addition, Porsche offers a new sliding glass sunroof as an optional feature for the 911 Carrera Coupé.

Prices start at SGD 407,888 for the 911 Carrera 4 (with PDK) - without COE of course.
