  7. 500-horsepower beasts new 911...

[YesAuto Racing Exposure] On the eve of the Nürburgring 24 Hours Endurance Race last weekend, Porsche released the latest 911 chassis race car, the 911 GT3 R, which is a purely competitive version of the new GT3 RS model, following the 500-horsepower power of the street version. Level.

Don't be too surprised, because one of the reasons for achieving such a power performance is that the engine displacement is increased to 4.0L relative to the old model, so that the 125 horsepower per liter can be considered a reasonable level for a high-performance naturally aspirated engine. The horizontally opposed 6-cylinder engine with variable valve timing uses direct injection technology. The fuel rail oil pressure is up to 200bar. The rear wheels are driven by a 6-speed sequential gearbox, which pushes the car with a weight of only 1220kg.

Compared with the old model, the new car uses an optimized aerodynamic design, the wheelbase has been extended by 8.3cm, and the front and rear counterweights have been optimized to make the new car in high-speed corners more competitive. The redesign of the car body and suspension system has also made a significant contribution to the lightweight of the car. The new aluminum alloy/stainless steel composite structure has proven to be one of the ideal design directions for the car, and the roof and the front luggage compartment External components such as covers, fenders, and doors are all made of carbon fiber composite materials. In addition, all windows are made of polycarbonate, and this time even the front windshield is also made of polycarbonate.

Another improvement of the new car is safety. The re-enhanced FT3 front fuel tank capacity has been increased by 12L, reaching a total volume of 120L. A safety shut-off valve has been added to the new fuel tank to prevent accidental fire. In an emergency, the doors and side windows of the car can be removed separately, and the emergency escape sunroof on the roof is also enlarged to allow the driver to leave the car in the shortest time. At the same time, the brake system of the racing car has been structurally enhanced and a more precise ABS anti-lock braking system is used. The single-piece forged 6-piston brake calipers on the front wheel with 380mm brake discs, 4-piston calipers and 372mm brake discs on the rear wheels provide powerful braking force for the racing car.

The overseas order price of the latest version of the 911 GT3 R race car is approximately RMB 3.02 million and will be officially delivered in December 2015. But to be honest, friends who are not very familiar with Porsche may not be able to recognize the new car. After all, the 911 car series has inherited too many traditional appearances since its inception. This may be the idea of a German sports car, traditional in appearance and wild in heart.
