CHRIS HARRIS MEETS PORSCHE R&D CHIEF
Wolfgang Hatz quizzed by Harris on diesel V8 Panameras and the return of the Mezger flat-six in the RSR
PH has been chatting to a lot of senior Porsche folk of late but having focused on design Harris has been talking engineering with head of research and development Wolfgang Hatz on the LA show stand on which the new Cayman was unveiled. Hatz's past CV includes spells at BMW Motorsport, a move to Porsche for F1 engine development in 1989, Technical Director at Opel's motorsport division and then serving as head of engines and transmission development at Audi before expanding this role to the whole VW group in 2007. He's been the Porsche board member in charge of R&D since 2011.

Lovely RSR photos just shown. Is it true that the RSR and Cup car will usethe old Mezger engine and not the new DFI motor?
[Grimacing] "I know where the photos were taken and I don't know how they did it. We want to participate next year [the next day Manthey were announced as running factory 991 RSRs at Le Mans 2013] and, yes, the RSR and Cup will use the old engine. It is very reliable and strong and it does a good job and in the Cup it will be 3.8 litres. It was an easy decision."

The Porsche 911 GT3 Cup is the most successful race car in the world. Since 1998, 2,395 units of the near standard vehicle for customer sport were produced. The new edition of the 911 GT3 Cup is the motorsports version of the future 911 GT3 and as such is the first race car that is based on the seventh generation of the sports car icon from Zuffenhausen. The 911 GT3 Cup will be run exclusively in the Porsche Mobil 1 Supercup in 2013. The car for one-make racing made its debut on the occasion of the end of motorsport season “Night of Champions” celebration at the R&D Centre in Weissach.
The new Porsche 911 GT3 Cup is powered by a 3.8-litre six-cylinder flat engine. It generates 460 hp (338 kW) at 7,500 revs, surpassing the predecessor by 10 hp. A six-speed dog-type gearbox developed by Porsche Motorsport which is operated via shift paddles at the steering wheel for the first time in a Porsche brand trophy race car transmits the power to the rear axle. The single piece race wheels with centre mount were also newly designed by Porsche Motorsport. The width of the Michelin race slicks was increased by two centimetres to 27 centimetres at the front and by ten millimetres at the rear axle to now measure 31 centimetres.
A newly developed race braking system further improves the excellent endurance qualities compared to its successful predecessor. The 380 millimetre slotted and inner-vented steel brake rotors at the front axle are decelerated by six-piston aluminium fixed callipers. The rear axle features a four-piston version. During the development of the new car a particular emphasis was put on the driver safety. A newly designed safety cage protects the pilot in case of a roll or a collision as does a newly developed race seat which is distinctively shaped around the head and shoulders and can be adjusted individually with the help of padding. A rescue hatch in the roof provides easy access for primary medical attention and for the extrication of the driver.
“The new 911 GT3 Cup is much easier to drive at the limit,” says Porsche works driver Timo Bernhard, who was significantly involved in the development of the new vehicle. “The car is excellently balanced. The new axle geometry is enormously positive for the handling. Apart from that the new Cup 911 is great fun to drive.”
Like its predecessor the new Porsche 911 GT3 Cup is produced in Stuttgart-Zuffenhausen on the same assembly line as the road legal models. At the Motorsport Centre in Weissach it receives a general set-up for the circuit and is tested by a professional race driver before delivery to the customers. The basic price for the vehicle, which is available exclusively in white, is 181,200 Euro plus the country-specific value added tax. –sn, Quelle: Porsche AG
