While the first Cayenne, known internally as the E1, was created under the direction of head of design Harm Lagaay, since 2004, Michael Mauer has been responsible for the design of Porsche models. . His idea was to take the Cayenne further, although the designers of the second-generation (E2) car launched in 2010 faced the same challenges as the first Cayenne. This means that the doors are identical to those on the VW Touareg model, built on the same platform, with limited design options. “However, in the case of the second Cayenne, the economic success of the model gave us a little more creative freedom,” recalls Mauer today.
Easily recognizable flight path and lower seating position
This means more work can be done on some elements. The doors are still the same, but the windows have changed. At the front, the exterior mirrors move from the corner of the window to the shoulder of the door, creating a more dynamic look and creating space for additional precious lights in the A-pillars.
At the rear, the side windows are pulled in higher behind the doors, the Cayenne’s roof spoiler extends to the rear, the taillights are placed slightly higher and the D-pillar is more inclined. The result is an elongated window shape and the roofline – known as the flyway in Porsche – slopes significantly to the rear. This makes the Cayenne look quick even when it’s stationary.
Porsche designers also have the freedom to add more personal touches to the interior: “The seating position is completely different now,” explains Mauer. “At E2 you sit in the car, not on it. This is a marked difference from E1. The lower seating position is also visually emphasized by the protruding front center console, which draws on the design of the center console on the Panamera sports sedan (launched 2009) with a conscious effort. to create brand identity.
At the same time, the second Cayenne gave Porsche the opportunity to use its own instrument cluster, with the tachometer centered in the familiar Porsche style. The steering wheel is borrowed from the iconic 911 sports car. “For customers who have 911 and Cayenne in their garage, this disconnect now no longer exists,” says Mauer.
More agility on the road and reliability off-road
Technically, Porsche has also gone in a new direction with the second Cayenne, for example by eliminating the low-range transmission that made the first Cayenne one of the best all-terrain cars while also delivering desirable performance. waiting for a Porsche. Oliver Laqua, involved at the outset as developer and now overall vehicle project manager, clearly remembers the transfer case discussion: “During the further development of the vehicle control system, electronic control, we have made a big step forward in control quality and speed. As a result, we were able to have the same off-road capabilities as the E1 in the new design of the E2 without the need for a gearshift or low-range transmission, and thus we were able to save a great deal of weight. ”
The use of the eight-speed Tiptronic for the first time combined with the new controlled all-wheel drive system with Porsche Traction Management (PTM) gives the new Cayenne road agility and reliability. reliability when crossing the terrain through electronic means. The new PTM also allows for lighter cardan shafts on the front axle, as well as lighter bearings. Combined with the absence of a transmission, Porsche has reduced the weight of the new Cayenne by 33 kg with the powertrain alone.
Efficiency was a big theme in E2, and lightweight construction was pursued elsewhere as well. The body lost 111 kg, with 39 kg being saved only in the doors and the doors. The tailgate – now made entirely of aluminum, like the wings – weighs half as much as the first Cayenne.
Together with the Tiptronic and the new engines, this consistent lightweight construction has resulted in significant improvements in fuel economy figures. Thermal management, variable deceleration fuel cut and start-stop function greatly reduce fuel consumption. The biggest contribution is due to the new automatic transmission. Only the new Cayenne with its 3.6-liter V6 and 220 hp (300 PS) is offered with a six-speed manual transmission as standard. This made the consumption of the car in the NEDC (New European Driving Cycle) 11.2 l/100 km, which was valid at the time. If customers order the optional eight-speed Tiptronic, consumption is 9.9 l/100 km – about 20% less than the first entry-level Cayenne.
The first Porsche hybrid goes into mass production
The new Cayenne S with its 294 kW (400 PS) 4.8-liter V8 consumes 10.5 l/100 km – 23% less than its predecessor. The new Cayenne Turbo also benefits from the same V8 petrol engine but delivers 368 kW (500 PS). Along with the Cayenne Diesel (180 kW/245 PS), the most economical in the range is the 279 kW (380 PS) Cayenne S Hybrid. The first hybrid model produced by Porsche in the series has a NEDC consumption of 8.2 l/100 km.
The powerful parallel full hybrid could be used more flexibly and efficiently than the split-power full hybrid that most competitors were advocating at the time. The Cayenne S Hybrid can go up to 60 km/h in pure electric mode. Boosting, restoring energy and extending time allows for a sporty and efficient driving experience. Thus, the second generation Cayenne laid the groundwork for Porsche’s successful electrification strategy 12 years ago. And the fundamental changes made between generations have been appreciated by our customers. The E2 helped Porsche almost double the number of deliveries compared to the first Cayenne. Between 2010 and 2017, a total of 535,903 models assembled at the Leipzig plant were delivered.
