The all-wheel drive 911 Carrera 4 and Carrera 4S will enter the market in both Coupé and Cabriolet guise, featuring two engine and transmission variants offering improved driving dynamics and lower fuel consumption.
The 911 Carrera 4 models share their all-new Direct Fuel Injection (DFI) flat-six engines with their rear-drive Carrera 2 cousins.
Depending on the drivetrain set up, the all-wheel-drive 911 Carrera offers up to 8.5 percent more power, fuel economy improved by up to 12.9 percent, and 15.4 percent lower CO2 emissions than the previous generation.
The 3.6-litre engine in the Carrera 4 produces 254kW and offers fuel consumption of just 10.1L/100km with the PDK transmission.
Whilst the Carrera 4S uses a 3.8-litre power unit, with peak output rising to 283kW resulting in a negligible increase to fuel consumption - just 10.7L/100km for the Cabriolet model.
In these new models, the all-wheel drive is now provided by an electronically-controlled Porsche Traction Management (PTM) system, which replaces the former all-wheel drive with its viscous multiple-plate clutch.
First developed for the higher spec Turbo models, the PTM system delivers an infinitely variable torque split, and is able to distribute up to 100 percent of traction to the front or rear wheels.
Coupled with the new seven-speed Porsche Doppelkupplungsgetriebe (PDK) - literally Porsche double-clutch gearbox - which boasts shift times up to 60 percent faster than a conventional automatic transmission, giving the new 911 Carrera models a proven performance edge.
The styling can only be described as evolutionary - comprising of only minute tweaks and functional refinements including bi-xenon headlights and new LED daytime driving lights as standard.
Inside, the updated range adds the new Porsche Communication Management (PCM) centre console comprising of a large touch screen operating the audio and navigation systems with integrated Bluetooth, USB and iPod connectivity.
