Porsche 911 Carrera 4

Permanent four-wheel drive with optimal power distribution

Like its predecessor, the latest generation 911 Carrera 4 comes as standard with four-wheel drive. Variable distribution of engine power to the front axle via a viscous clutch in the front differential guarantees excellent traction and supreme driving safety on all kinds of roads and under all types of conditions.

Porsche Stability Management (PSM)

The 911 Carrera 4 is fitted as standard with Porsche Stability Management, or PSM, a sophisticated electronic system that intervenes in the engine management and braking systems to stabilise the car in both longitudinal and lateral directions whenever the car is driven to - or beyond - the limit. And PSM has been tuned by Porsche suspension engineers to ensure that the sporting character of the 911 is not compromised by premature intervention of the system. In fact, the objective in calibrating the PSM system was to provide brief but essential assistance to all four wheels, to maximise driving dynamics and stability.

Superior safety characteristics, outstanding driving qualities

The springs, dampers and anti-roll bars are specially tuned and modified to reflect the dynamic driving qualities of the four-wheel drive model. Careful adjustment of the axle geometry for the requirements of four-wheel drive, and retuned elasticity of the front axle, ensure neutral handling behaviour all the way to extreme limits, particularly through corners.

320bhp spread between all four wheels

Displacing 3.6 litres and developing a maximum of 320bhp (235kW), the Carrera 4’s power unit ensures supreme performance, with a minimum of 5 per cent and a maximum of 40 per cent of the drive going to the front wheels, depending on road and driving conditions. Acceleration from 0-62mph (100km/h) is the same as for the rear-wheel drive Carrera, exactly 5.0 seconds. Top speed (with the six-speed manual gearbox) is also identical, at 177mph (285km/h).

Discreet Distinction Applying the principle of great to look at, even better to drive, the Carrera 4 does not flaunt its wares. Carrera 4 badging stands out in titanium colour on the engine cover, and also appears discreetly on the black wheel hub covers. Titanium-coloured brake callipers are a further identifying feature of the Carrera 4.
