Porsche Cayenne Turbo GT Coupe: most powerful version of SUV has 631bhp

Published: 29 June 2021

► Fastest, most powerful production Cayenne
► New performance SUV has Urus-rivalling punch
► Cayenne Turbo GT is a new ‘Ring record holder

Porsche has unleashed its newest variant of the Cayenne, and it’s all about power. The new Cayenne Turbo GT, available exclusively as the four-seat coupe version of the brand’s SUV, is the fastest and most powerful one Porsche has created.

The Turbo GT still uses a 4.0-litre twin-turbo V8, but power is rated at 631bhp and 627lb ft – 79bhp more than the Cayenne Turbo. Porsche claims the new Turbo GT can sprint to 62mph in 3.3 seconds – not far off a 911 Turbo and 0.6 seconds quicker than a Cayenne Turbo Coupe – and a top speed of 188mph. 

On top of the raw power, the new Turbo GT sits up to 17mm lower, with retuned air suspension and recalibrated suspension management (including Porsche’s active suspension management and dynamic chassis control) systems for a sharper ride. The front wheels are an inch wider with an increase in negative camber of 0.45 degrees to give the new Pirelli P Zero Corsa tyres a bigger contact patch. Porsche’s ceramic brakes are standard, too, as is a sport exhaust system with central-mounted tailpipes, and tweaks have been done to the all-wheel drive system.

As for the look, details like the wheels, rev counter and Sport Chrono clock are finished with gold-hued ‘neodyme’, with carbonfibre bodywork and a new fixed rear spoiler. Porsche also says that the Cayenne Turbo GT is one of the first cars to get the brand’s latest infotainment system.

All of that additional performance engineering has meant Porsche has claimed a new Nurburgring record for SUVs: 7m 38.9s.

Want a Turbo GT? You’ll need at least £143,910 before you add any extra options.

Porsche Cayenne GTS: what you need to know

In an unusual move, Porsche has gone back to V8 power for its new Cayenne GTS - which had previously dropped the cylinder count from eight to six. Sonic ambition is assured, then, as well as offering more poke than the V6 it replaces.

Key stats for the new 2020 Porsche Cayenne GTS are as follows:

  • Engine 4.0-litre bi-turbo V8 (up from 3.6 V6)
  • Transmission Eight-speed Tiptronic S auto
  • Power 454bhp (+19bhp)
  • Torque 457lb ft (+15lb ft)
  • 0-62mph 4.5sec (-0.6sec)
  • Top speed 173mph (+5mph)

That derestricted top speed is with the Sport Chrono option fitted, which lifts the v-max from 155mph. Note how most brightwork is dulled by black accents, including the smoked window surrounds, spoilers and Porsche model badges. 

The rise in capacity and power has had an inevitable effect on the claimed economy and emissions: Porsche's V8 sounds inherently thirsty, with 20-21.2mpg claimed on the combined WLTP cycle, with CO2 standing at a lofty 301-319g/km.

Porsche Cayenne review

What's new?

Porsche uses the GTS badge to denote the sweet spot of not-quite-GT models across its range - and it's no different on the Cayenne. There's a raft of athletic improvements to endow this SUV with a little more sporting intent.

The chassis drops 20mm and PASM adaptive dampers let drivers soften or toughen up the damper firmness, for comfort or sporty settings. Steel springs are standard, but air suspension is an option. Huge 390mm diameter front brakes wipe off all the speed, and owners can order Porsche Ceramic Composite Brake (PCCB) for even beefier anchors.

Twin central exhausts for Cayenne GTS Coupe

The Cayenne GTS Coupe gets twin central oval exhausts (above), distinct from the rear end of the SUV. Much attention has been paid to the sports exhaust note, according to Zuffenhausen.

Inside, the interior is festooned with soft-touch Alcantara and brushed aluminium.

Prices and specs

The Cayenne GTS is available as the regular SUV (red picture above) and in the swoopier Cayenne Coupe bodystyle (grey car). Prices in the UK have been confirmed at £85,930 for the regular bodyshell and £88,750 for the coupe.

Orders are being taken by the newly reopened Porsche centres now, with first right-hand drive deliveries due later in summer 2020.
