The third-generation Porsche Cayenne is now joined by the peak of the range, the V8 biturbo petrol-engined Cayenne Turbo. Under its hood is a 4.0 litre, twin-turbocharged V8 petrol mill producing 550 hp and 770 Nm of torque as featured in the Panamera Turbo, representing gains of 30 hp and 20 Nm respectively over the previous Cayenne Turbo.

Headline performance figures are thus: 0-100 km/h is attained in 4.1 seconds (3.9 seconds with Sport Chrono package), and onwards to a top speed of 286 km/h. Driveline as par for the Cayenne course is all-wheel drive, receiving the engine’s output via an eight-speed Tiptronic S torque converter automatic transmission.

Chassis equipment draws from the base Cayenne and Cayenne S which arrived just before this Turbo model. This comprises three-chamber adaptive air suspension, Porsche Dynamic Chassis Control (PDCC) roll stabilisation and Porsche Torque Vectoring (PTV), along with optional rear-wheel steering.

As with the two six-cylinder third-generation Cayennes, the Cayenne Turbo adopts what Porsche calls mixed tyres, which mean tyres of staggered widths front and rear. The 21-inch diameter Turbo design wheels are mounted with 285/40 and 315/35 section tyres front and rear respectively, which contributes to better longitudinal and lateral power transmission, says Porsche.

On its exterior, the Cayenne Turbo gains a front end with a more imposing front bumper and intakes, while the headlamps also distinguish the Turbo from lesser models with double-row light modules. The 21-inch Turbo wheels are exclusive to the range-topping Cayenne, which reside within widened wheel arches with painted wheel arch trims.

Around the back, the V8-powered Cayenne also gets white painted rear bumper trim and door trim to go with the signature Turbo quad rectangular exhaust tailpipes. As with the other Cayennes, the Cayenne Turbo also gets a full width red light strip which bridges the two main tail lamp clusters, as well as an SUV-first roof-mounted adaptive spoiler, which Porsche says reduces braking distance from 250 km/h by up to two metres.

Speak of braking, the Cayenne Turbo comes as standard with the new Porsche Surface Coated Brake (PSCB) which employs a tungsten-carbide layer on the steel discs for increased braking performance and reduced wear and brake dust, as featured on the six-cylinder Cayennes. The top braking equipment specification remains the optional Porsche Ceramic Composite Brake (PCCB) system.

With the new high-resolution display and touchscreen of the Porsche Advanced Cockpit featured in the interior of the latest generation of Cayennes, the Cayenne Turbo follows suit, with a 710-watt Bose surround sound system as standard. The seats draw inspiration from the 911 in having integrated headrests, and are heated as standard.

Orders for the Cayenne Turbo in the European market are being taken, and it is set to arrive at the end of this year. In its native Germany, the Porsche Cayenne Turbo is priced at €138,850 (RM699,446) including VAT.
