Porsche Unveils New Cayenne Initially Without Diesel Engine

Patrick Schäfer

Porsche has unveiled the third Porsche Cayenne generation. This SUV will be available with two newly developed six-cylinder petrol engines when it is launched. 

Now 63 millimetres longer at 4,918 mm, the new Cayenne is 1,983 millimetres wide and up to 65 kilograms lighter than its predecessor. Overall, its kerb weight decreased from 2,040 to 1,985 kilograms. "We have completely redeveloped our successful model. It has been visibly and tangibly improved and perfected in all respects. The Cayenne has also been digitalised and networked throughout to give it a forward-thinking design", says Oliver Blume, Chairman of the Executive Board at Porsche.

The power output from the 250 kW (340 hp) three-litre turbo engine in the Cayenne has increased by 29 kW (40 hp). Now 15 kW (20 hp) more powerful, the 324 kW (440 hp) 2.9 l V6 biturbo engine in the Cayenne S can accelerate it to up to 265 km/h. Power is transmitted by a new eight-speed Tiptronic S gearbox. 

Enhanced on-road properties

The SUV features active all-wheel drive as standard. Together with mixed-size tyres, rear-axle steering, three-chamber air suspension and electric roll stabilisation, the systems should improve the dynamic driving properties on the road. The lightweight chassis base, a front axle with separated link design and a multi-link rear axle should more readily allow the Cayenne to combine a sports car, a saloon and an off-roader into a single vehicle. A new high-performance brake is also available: the optional Porsche Surface Coated Brake (PSCB) consists of a grey cast iron disc coated with tungsten carbide. It should increase the friction values whilst decreasing the wear and the amount of brake dust.

Full-HD touchscreen

The central rev counter in the instrument cluster is flanked by two seven-inch displays. A 12.3 inch full-HD touchscreen as used in the Panamera controls the infotainment functions. The Cayenne is networked and on-line as standard, allowing it to access on-line services and the internet for on-line navigation and real-time traffic information, for example. Owners can personalize the Porsche SUV on many levels. They can save their preferences for the start screen, interior settings, main menu, lighting, driving programs and driver assistance systems in up to six profiles.  

According to Porsche, the most important driver assistance systems include Night Vision Assist with infrared camera, Lane Change Assist, Lane Departure Warning including traffic sign recognition, Traffic Jam Assist, ParkAssist with Surround View, as well as adaptive cruise control.

Porsche is taking a wait-and-see approach to diesel engines

It is apparently still uncertain whether the third Porsche Cayenne generation will be equipped with a diesel engine. The current model with a 3 l diesel engine has to be recalled for a software update due to possible tampering. The German Federal Ministry of Transport and Digital Infrastructure had even imposed a sales ban on the Cayenne Diesel. "We have not made a decision on it", Blume is reported by Handelsblatt newspaper to have said at the presentation, regarding whether the new Cayenne will receive a diesel engine.
