The new Porsche 911 Carrera 4 unites the performance and efficiency of the new, seventh-generation of the 911 Carrera with the dynamic benefits of the latest version of the active all-wheel-drive system PTM (Porsche Traction Management). The typical Porsche all- wheel-drive system with focused rear bias in this latest 911 version promises maximum vehicle dynamics on a wide variety of road surfaces and in all weather conditions. The new 911 Carrera 4 models deliver traction and dynamic performance to the fourth power.

The new all-wheel-drive 911 is being launched in four versions – the 911 Carrera 4 and 911 Carrera 4S, each as Coupé and Cabriolet. They sport the same traits as the rear-wheel drive versions: their lightweight body design, suspension, engines and gearboxes are identical, the only exception being modifications related to the all-wheel-drive. This means that despite a higher level of engine and driving performance, all four models consume significantly less fuel than the previous models; total savings for individual versions are as much as 16 per cent. In addition, the new 911 Carrera 4 is up to 143 lbs. (65 kg) lighter in weight when compared to the previous generation 911 Carrera C4.

The most distinct identifying feature of the 911 with all-wheel drive is the wider rear section: compared to the two-wheel drive 911 Carrera models, the rear wheel housings each extend further outward by 22 mm for a total of 44 millimeters, and the rear tires are each ten millimeters wider. The traditional red light band that connects the two taillights on the 911 Carrera C4 has also taken on a new form.

The Coupé and Cabriolet of the 911 Carrera 4 S each have a 3.8-liter rear-mounted boxer engine that produces 400 hp; this enables acceleration to 60 mph in 3.9 seconds (Cabriolet: 4.1 seconds) and a top-track speed of 185 mph (Cabriolet: 183 mph) with a suitable equipment configuration. Fuel consumption values with PDK are EPA estimated at 19 mpg city and 26 mpg highway for both the Coupé and the Cabriolet.

New: all-wheel drive indicator, Porsche Active Safe (PAS), sliding glass sunroof, extended Sport Chrono pack
In the new 911 Carrera 4, an additional 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 making the optional Adaptive Cruise Control (ACC) available 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. Driving 911 cars with a manual gearbox and Sport Chrono pack can now be even sportier: In Sport Plus mode, the system automatically double-declutches during downshifts.
The new all-wheel drive models replace a very successful previous generation, of which 34 percent second-generation 997 models where all-wheel-drive. This previous generation launched with one of the greatest development steps in powertrain technology that the 911 ever made: new were the engines with direct fuel injection, Porsche Doppelkupplung (PDK) gearbox and electronically controlled Porsche Traction Management (PTM). In July 2011, Porsche crowned the model series with the 911 Carrera 4 GTS, whose 3.8-liter engine was boosted to 408 hp.

The new Porsche 911 Carrera with all-wheel-drive will make its first public appearance at the 2012 Paris International Motor Show September 29, 2012. The new 911 models will launch in the US early in 2013. The 2013 911 Carrera 4 will have a base MSRP of $91,030, and the 911 Carrera 4 Cabriolet base MSRP will be $102,930. The 911 Carrera 4S will have a base MSRP of $105,630 and the Cabriolet will have a base MSRP of $117,530.
