It ‘really’ is another week, another Porsche – since this is the 3rd week in a row that the Stuttgart sports car manufacturer has launched a new product – this time its an all-wheel drive version of the 911 Carerra GTS which went on sale in two-wheel drive form last December.
The 911 Carrera 4 GTS power unit has its origins in the 3.8-litre, six-cylinder from the Carrera S and has received a comprehensive redesign of the intake duct adding 23 bhp, taking the peak power output to 402 bhp at 7,300 rpm.
The improvement in the engine’s breathing not only increases peak power output but also its flexibility thanks to a more generous torque curve in the lower and middle engine speed range. For example, 320 Nm is available from as low as 1,500 rpm; overall, the six-cylinder engine delivers its peak torque of 420 Nm across a broad engine speed range from 4,200 – 5,600 rpm.
Complimenting the uprated engine is a sports exhaust system which produces a distinctly sporty sound – the new Carrera 4 GTS has an unmistakable acoustic signature, and this unique character is enhanced by exhaust tailpipes finished in a distinctive black surface design.
While the engine is identical to that used in the two-wheel drive Carrera GTS, the four-wheel drive version features Porsche Traction Management (PTM) to offer even more driving stability and traction. The PTM achieves this by directing the optimal proportion of the engine torque to the front wheels via a multiple-plate clutch. Furthermore, the Carrera 4 GTS features a limited-slip rear differential as standard which contributes to the dynamic performance of the electronically-controlled all-wheel drive system, and underlines the driving focus of this new model.
The Carrera 4 GTS is fitted as standard with a six-speed manual transmission, and the Coupé model sprints from 0-62 mph in 4.6 seconds, the Cabriolet in 4.8 seconds. If equipped with the optional Porsche-Doppelkupplungsgetriebe (PDK) seven-speed double-clutch transmission, which helps trim an additional 0.2 seconds from its acceleration times.
As with all of the latest Porsche models the Carrera 4 GTS is a product of the Porsche Intelligent Performance process, thus the fuel economy of these new all-wheel 911 models is identical to that of the equivalent 380 bhp 911 Carrera 4S models. For example, the Carrera 4 GTS Coupé returns 26.9 mpg with CO2 emissions of 247 g/km.
Visually, the new Carrera 4 GTS model receives the usual all-wheel drive 911 styling features – the designation on the doors and rear lid, plus an additional reflective stripe between the tail lights. As well as the characteristic all-wheel drive wide body style, increased rear track width is added, a specification that is unique to all GTS models.
In numerous other details, the GTS models differ both visually and technically from the other Carrera models. For example, they run on 19 inch RS Spyder alloy wheels in black with a central wheel bolt and gloss-finished rims, whilst 305/30 ZR 19 tyres are fitted on the rear axle.
Additional visual features include the Sport-Design front apron with black painted spoiler lip and special side skirts, also in black. Inside, there are sports seats for driver and passenger. The GTS comes fitted with black Alcantara trim on seat centre panels, steering wheel rim, gearshift and handbrake lever, door handles and door storage box lid. Porsche Communication Management offering touch-screen controls for the audio system is a further highlight.
The 911 Carrera 4 GTS Coupé and Cabriolet goes on sale in the UK in July 2011, priced from £83,145 for the Coupé and £90,024 as a Cabriolet.
