Porsche has launched a new variant of the Cayenne GTS, now donning a sporty chassis and powered by a tuned non-turbo 4.8-litre V8, at the 2012 Beijing International Auto Show. The newest variant of the Porsche Cayenne GTS will be a midpoint between the S and Turbo models. The newest version, however, will be powered by a similar but more powerful non-turbo 4.8-litre V8 lying on the hood of the Cayenne S.
Meanwhile, the V8 on the GTS offers 414 bhp compared to the 394 bhp of the S. Power is transmitted to the wheels via a standard eight-speed ZF automatic gearbox with stop-start. This engine-transmission combo offers a slight change from the previous version of the GTS, which offers around 400 bhp channeled via a six-speed manual gearbox.
With the powertrain upgrade, the newest version of the Cayenne GTS exhibits improved performance. The present GTS could accelerate from zero to 62 mph in 5.7 seconds, a 0.2 second improvement over the acceleration time of the current S.
The newest GTS is also 2 mph faster than the V8 S at 160 mph. Both sports cars logged similar acceleration times on the zero to 100 mph gauge, at 13.3 seconds.
However, due to GTS’s more powerful engine, it gulps more fuel than the V8. The newest GTS could travel 26.4 miles per gallon, not as good as the 28.9 miles per gallon that the V8 S offers.
Porsche paid more attention to the GTS chassis, setting it lower than the previous GTS, but comes with standard steel springs and PASM adjustable dampers.
The newest GTS’s ride height is 24mm lower than that of the Cayenne S and the previous GTS. Lower chassis ensures more stable cornering and lesser body roll. A buyer could upgrade the suspension of the newest GTS by opting for the air suspension combined with Porsche’s PDCC anti-roll system.
Considering that the new Cayenne GTS has a body that is lower by 24 mm when compared to the Cayenne S, Porsche knew that in order to get excellent driving dynamics, the configuration of the new chassis would play an important role. Thus while a steel spring suspension is fitted in as standard, there is the option to have air suspension, which will make the Cayenne GTS lower by only 20 mm versus the Cayenne S.
Because the ride height is low, it means the center of gravity is low as well. This has a significant impact on the vehicle’s agility, especially when cornering. Regardless of what suspension the customer decides to have, both will have the Porsche Active Suspension Management or PASM.
What this feature does is to manage how the shock absorbers are electronically adjusted. In addition, depending on the driving style as well as the current condition of the road, the PASM constantly and actively regulates the damping forces. When the PASM is combined with the improved chassis mounts, the overall result is that the Cayenne GTS is able to show a spread of comfort and sportiness never before seen. At merely the push of a single button, the driver has the option to decide which one to experience. Enhancing the unique sporty handling of the Cayenne GTS further are the 20-inch wheels from RS Spyder.
With the wider wheel arches, the wheels have been positioned to its outer edges to serve as counterbalance. To make this possible, it meant that the Cayenne GTS would have a rear axle track 17 mm greater when compared to the Cayenne S. Customers who opt to have the air suspension will get to experience five different levels for the height. These ensure that the performance is indeed uniquely Cayenne GTS and is ultimately different from the air suspension inside the Cayenne S.
