Article by Christian Andrei, on January 16, 2012

After Techart, another German Porsche tuner announced its customization programme for the 2012 Porsche 911 (991). Dubbed SpeedART SP91-R, the new bodykit will be available in three versions. The first step is very elegant and features the CS-rear wing and modular 21" LSC-FORGED wheels. A wider version will be unveiled in March at the 2012 Geneva Motor Show.

In terms of power, SpeedART will offer different levels of power kits for for both brand new 991 Carrera and Carrera S engines.

In addition, a new sport exhaust system with sport-catalysts and manifolds (optionally combined with a sound switch function) will be available as well as some ECU tweaking offering up to 25 hp and 20 Nm.

The suspension will also be offered for street and race track. SpeedART will also offer an airlift suspension to maintain the everyday practicability of cars with the SP91-R bodykit.

Ready for the sales launch of the 991 the modular LSC- FORGED wheel will be availiable for ordering in 20" and 21.

SpeedART will offer many differenent exclusive interior solutions with alcantara and leather as well as sport steering wheels with F1 shift paddles and many more. More details and photos will be revealed at the 2012 Geneva Motor Show.

In terms of design, the evolution of the style implemented on the Porsche 911 Carrera is evident no matter where it is viewed. With the front end being made wider and redesigned, it is not surprising that the headlights are new and the side air intakes have been made larger. On the rear, the addition of a variably extending spoiler helps highlight the fact that this new offering has greater power output.

Completing the look of the rear are the redesigned lights, which use LED technology and now narrower. When looked at on the side, one can immediately sense that the 911 Carrera has a quality similar to a coupe.

This could be because the windscreen was made more convex with the addition of larger alloy wheels having a new design. These different changes, when paired with the various aerodynamic optimizations, resulted in reducing the lift while making sure that the cd value remained to be excellent. Aside from the changes to the design, there are a number of new features fitted in the 911 Carrera.

Equipped as standard for example, is the manual 7-speed transmission. This is the first time such a transmission is equipped inside a passenger car and in addition is based mainly on the seven-speed Doppelkupplungsgetriebe’s (PDK) module, though the latter is offered as an option. What this means is that since the first six gears display a close ratio, it enables the driver to experience the excellent acceleration capability.

Meanwhile the 7th gear brings with it quasi-overdrive qualities that help enhance the fuel economy. For customers who decided to have their 911 Carrera fitted with the PDK transmission, they will get the opportunity to experience the sailing function, a first for a sports car with this type of transmission. Factoring in the current driving situation, once the driver stops pressing on the accelerator, the system disengages the engine from the transmission.

The 911 Carrera can therefore move forward with its engine idling. When driving at higher speeds, this particular function can help get that added fuel economy and in fact for daily driving, can save fuel amounting to 1 liter for every 100 kilometers.

Another new feature is that the 911 Carrera comes equipped with the auto start/stop function, another first for a sports car. This function can be paired with either the standard manual transmission or even the option PDK. With this function, the 911 Carrera, using the New European Driving Cycle rating, can save at most 0.6 liters of fuel for every 1/100 kilometers.

Helping lower fuel consumption by as much as 0.35 liters for every 1/100 kilometers are the on-board electrical system and the joint thermal management system made for the transmission and engine. Aiding with the performance as well is the new cooling design which removes the need to have the underbody ventilation openings. This also brings aerodynamic benefits as well.

While the fuel consumption of the 911 Carrera is indeed optimized, this is complemented by the downsizing that the brand is known for. Thus the 3.4-liter engine equipped delivers more power at a 3.6-liter displacement, smaller when compared to the previous model. When fitted with the PDK, the new 911 Carrera becomes the first in the brand to have CO2 emissions below 200 g/km.

Finally with regards to the Porsche Intelligent Performance, it is the 911 Carrera that sets new benchmarks. The wide array of functions and new components when combined with the advanced lightweight body made of aluminum steel, results in a good balance between driving dynamics and efficiency.
