Porsche has just released the production model of their most high-performance Cayenne model called the Cayenne Turbo GT.
In the build-up to the official unveiling today, Porsche’s test drivers provided highly positive feedback regarding the higher performance threshold (steering, precision and acceleration) of this new Cayenne Turbo coupe model.
The new Porsche Cayenne Turbo GT, only exclusively available as a four-seater coupe bodystyle, comes with heavy revisions to the powertrain and chassis. Think of it as the Turbo S version of the Cayenne model.
Under the bonnet is the 4.0-litre twin-turbocharged V8 engine, now producing 640 hp and a monstrous 850 Nm of torque. The figures represent a 90 hp and 80 Nm increase over the ‘regular’ Cayenne Turbo Coupe. Porsche have upgraded the crankshaft, pistons, con-rods, turbochargers, fuel delivery, induction and intercooler systems to achieve better response and power delivery of the V8 engine.
Plenty of glorious V8 soundtrack can be heard thanks to a lightweight titanium sports exhaust system that deletes the centre silencer.
The transmission meanwhile maintains the same 8-speed automatic but massaged to shift even faster, allowing the big SUV to shave 0.6 seconds of the century benchmark sprint time to register just 3.3 seconds. Top speed of the Porsche Cayenne Turbo GT is 300 km/h, an increase of 14 km/h versus the non GT.
Compared to the Cayenne Turbo Coupe, the Turbo GT rides up to 17 mm lower. Based on this, both the passive chassis components and active control systems have been re-engineered and optimised for handling and performance, allowing Porsche’s test driver Lars Kern to register a record lap time at the Nurburgring Nordschleife.
Among the systems upgraded are the Porsche Torque Vectoring Plus system (electronically-controlled LSD), rear-axle steering, active roll stabilisation (PDCC) and 15% stronger chambers in air suspension.
Suspension geometry sees a negative-camber setting of 0.45 degrees and paired with wider 22-inch wheels and 285/35-section front tyres to ensure maximum contact patch from the specially-developed Pirelli P Zero Corsa tyres.
Braking duties are performed by the Porsche Ceramic Composite Brake (PCCB) system, with the front disc brakes measuring 440 mm in diameter and grabbed by 10-piston calipers.
On the outside, the new Cayenne Turbo GT features a model-exclusive front bumper with spoiler lip and enlarged cooling intakes. Black wheel arch extensions and special GT Design wheels in Neodyme finishing dominate its side view.
The new Cayenne Turbo GT also features a standard-fitted carbon-fibre roof panel that leads air to the larger roof spoiler and an automatic extending rear spoiler lip that is 25 mm larger than that fitted to the Turbo model. This increased downforce by up to 40 kg.
Inside, only two sport seats are fitted to the back row with all seats receiving exclusive Turbo GT stitching on the headrest. In this example, the tachometer and seat stitching as well as seatbelts are all finished in Neodyme highlights. Turbo GT emblems are also found on the lower console and doorsill decorative trim pieces.
The Cayenne Turbo GT is also the first model to feature the next-generation Porsche Communication Management (PCM) with a new interface, better performance and smartphone integration.
The new Porsche Cayenne Turbo GT is available to order now and will roll into dealerships in mid-September 2021. Prices in Germany start from EUR196,078 (RM910,300), over EUR25,000 dearer than a Cayenne Turbo coupe with the fancy electronic chassis control systems and ceramic brakes.
