Extreme sports cars have to undergo many difficult tests during development, but the new Porsche 911 GT3 had to withstand a really heavy load.

During the introduction of the new generation 911 GT3, Porsche representatives confirmed that they have applied racing technologies to the new model more continuously than ever before. However, completely different demands are placed on the road car compared to the private racing car, which goes to a specialized workshop after each race.

In order for the automaker to be sure that the new GT3 is able to provide the best performance for a long time on normal roads, it has rehearsed an unconventional stress test. At the famous Italian Porsche-owned Nardo Circuit, the new 911 GT3 had to travel 5,000 km at a speed of 300 km / h. The only stop was the fuel stop.


At the same time, testing mainly verified the capabilities and endurance of the 4.0-liter flat-bed six-cylinder engine, which should be nearly identical to the GT3 Cup racing-style engine according to the automaker. Thanks to various modifications, the engine can run up to 9,000 rpm, deliver the highest output of 375 kW (510 hp) and 469 Nm, with a PDK transmission reaching 100 km / h in 3.4 seconds and running up to 320 km / h.

In total, the new GT3 engine was put into operation in a 22,000 hour test circuit. During testing, we often simulate typical profile circuits and let the engine run at full throttle for an extended period of timeThomas Mader, Porsche GT Road Car Engines Project Manager, told the test.

In addition to the engine, improved aerodynamics was also tested, which also greatly contributed to the car’s ability to run at a speed of 300 km / h for about 16 hours at a time. Designers borrowed some ideas from not only the GT3 Cup, but also the 911 RSR.

The body has undergone a number of modifications, but the most important of them occurred in the front splitter area, especially the rear wing, which got handles in the style of swan necks. Thus the wing is connected from above, so that air can pass under its lower surface without undue disturbances.

Aerodynamics was tested in about 700 simulations and the vehicle spent a total of about 160 hours in a wind tunnel, where even the smallest details were refined. At 200 km / h, the new Porsche 911 GT3 creates downforce that is up to 50% more than its predecessor – in normal mode. When set to maximum pressure, the increase is up to 150%.

As Porsche adds, the new generation GT3 mainly benefits from the experience gained by auto technicians in racing machines and on the race track. “When the same technicians who develop our racing cars design new GTs on the road, this is the instant technology transfer I can imagine.Andreas Brioninger, GT Model Line director.
