We’ve seen the leaked images yesterday; now, the third-generation Porsche Cayenne has made its official debut at its home in Stuttgart-Zuffenhausen, Germany. At launch, the 2017 Cayenne comes in two variants – the base 3.0 litre turbocharged V6 model, and the Cayenne S, powered by a 2.9 litre, twin-turbocharged V6 engine, similar to two of the Panamera’s three petrol engines.

The base Cayenne’s 3.0 litre, single-turbo V6 produces 340 hp between 5,300 rpm – 6,400 rpm, and 450 Nm of torque between 1,340 rpm-5,300 rpm which goes to all four wheels via an eight-speed torque converter automatic transmission. Combined fuel consumption is rated at 9.2-9.0 litres per 100 km, and CO2 emissions at 209-205 g/km. Unladen weight for the base model is 1,985 kg.

Stepping up to the Cayenne S, a 2.9 litre twin-turbo V6 petrol features here with 440 hp between 5,700-6,600 rpm and 550 Nm of torque between 1,800-5,500 rpm. As before, transmission is all-wheel-drive via an eight-speed torque converter automatic. Combined fuel consumption is 9.4-9.2 l/100 km while CO2 emissions is rated at 213-209 g/km. The Cayenne S tips the scales at 2,020 kg unladen.

Acceleration times for both models are as follows: the base Cayenne does 0-100 km/h in 6.2 seconds (5.9 seconds with Sport Plus), 0-200 km/h in 24.2 seconds or 23.9 seconds with Sport Plus; the Cayenne S does 0-100 km/h 5.2 seconds or 4.9 seconds with Sport Plus, and 0-200 km/h in 18.9 seconds or 18.6 seconds with Sport Plus. Top speeds for the Cayenne and Cayenne S are 245 km/h and 265 km/h, respectively.

Expected to join the new Cayenne line-up is the the Cayenne Turbo, with a 4.0 litre twin-turbo petrol V8 with outputs similar to the Panamera Turbo’s 550 hp and 770 Nm of torque, as are a pair of hybrids – a ‘standard’ hybrid drawing ICE duties from the 2.9 litre biturbo petrol with a total system output in the region of 470 hp, and a top-end 680 hp V8 biturbo similar to that in the Panamera Turbo S E-Hybrid.

The Cayenne’s weight reduction over the previous generation comes from the combination alloy construction of its body, while the exterior is entirely aluminium. Floorpan assembly, front section and “virtually all chassis components” are also made of alloy, says Porsche.

As indicated in our prior spyshots, the E3 Cayenne is built upon the VW Group’s MLB Evo platform which also underpins the Audi Q7 and the Bentley Bentayga, which now opens the door to 48V electrical architecture, possibly for electric turbines in a future diesel variant, as deployed in the Bentayga Diesel.

As expected, the new Cayenne draws heavily upon the second-generation Panamera’s equipment list, with Porsche 4D Chassis Control, three-chamber air suspension, rear-axle steering, and Porsche Dynamic Chassis Control (PDCC) electronic roll stabilisation. Despite the additional equipment, the Cayenne is now up to 65 kg lighter, and remains just as capable off-road as before, according to Porsche.

To that end, programmed off-road modes allow the driver to select a preset choice for their off-tarmac excursions. With the default being Onroad, the other four modes are the self-explanatory Mud, Gravel, Sand and Rocks settings. Fully variable Porsche Traction Management (PTM) shuffles drive distribution between the axles.

The optional rear-axle steering works similar in principle to other Porsches thus equipped; the rear wheels steer in accordance with the fronts for added stability at high speeds (albeit at smaller angles), and in opposition at low speeds for better agility and a smaller turning circle for tight spaces.

Porsche claims a world first in braking technology with the introduction of the Porsche Surface Coated Brake (PSCB), which consists of a cast-iron brake disc with a tungsten-carbide coating in order to increase friction values (read: greater braking force), while reducing brake dust and wear. This will be optionally available on all Cayennes fitted with 21-inch wheels, while the PCCB carbon-ceramics remain the top brake specification.

Inside, the new Cayenne’s cabin follows the Panamera’s design particularly in the dash architecture, which here also features the latest generation of Porsche Communication Management (PCM). A 12.3-inch full-HD touchscreen provides access to infotainment and vehicular setups, with voice control for the former. Porsche Connect Plus brings online services with online navigation and real-time traffic information.

As in the Panamera, the central analogue tachometer is flanked by two seven-inch full-HD displays, with data displayed selectable from the multi-function steering wheel. Active safety systems with Night Vision Assist includes a thermal imaging camera, Lane Keeping Assist including traffic sign recognition, traffic jam assist, ParkAssist with Surround View and Porsche InnoDrive, which includes adaptive cruise control.
