The new Porsche 911 GT3 might not be much more powerful than its predecessor, but thanks to many other improvements it is significantly faster. The new GT3 circles the Nurburgring over 12 seconds faster than the previous generation of the model and to some extent this is possible due to the car’s top speed. According to official factory figures, the 2022 GT3 can reach a top speed of 197 miles per hour (317 kilometers per hour).
There is, however, something even more important. Endurance is the key word here, as Porsche wanted to create a performance machine that could run at full throttle for hours. Literally, and that’s not an exaggeration.
In a new press release, Porsche detailed some of the technical highlights of the new 911 GT3. There are several very interesting facts, but we are very excited by the information that the automaker tested a prototype of the 911 GT3 on a continuous stretch of over 3,106 miles (5,000 kilometers) at a constant speed of 186 mph. (300 km / h). ) stopping only for fuel. The test was carried out on the oval at Nardo’s in Italy and the car passed the evaluation “perfectly”.
To ensure that the engine could run for hours under a heavy load, Porsche engineers had to create a very complex oil supply system. In fact, the new 911 GT3 uses an oil system which is roughly identical to the company’s racing cars and has a total of seven suction stages. “The engine in our 911 GT3 Cup racing car differs essentially in just two components: the exhaust system and the engine control unit. Everything else is the same, ”explains Thomas Mader, specialist in GT road car engines at Porsche.
But before the engine was ready to hit the Nardo track for countless hours of endurance testing at full speed, it had to go through a practice session on the static test bench. Specifically, he spent over 22,000 hours under different simulations, based on typical circuit profiles. Mader says the engine has been tested “at full throttle for a very large part of the time.”
