New cars are put through rigorous testing before they hit the market. This applies not only to the models that you and I can buy, but also to exotic sports cars. The new Porsche 911 GT3, for example, which was recently unveiled. Unlike the current Carrera models and the 911 Turbo, the 911 GT3 does not have a turbo engine, but a high-revving naturally aspirated six-cylinder with a displacement of 4.0 liters. The boxer block only turns into the limiter at 9000 rpm and delivers 510 hp and 470 Nm. That is 10 hp and 10 Nm more than the previous generation.
Six-cylinder boxer engine 22,000 hours on the test bench
The six-cylinder was put on a test bench by Porsche for 22,000 hours, during which he spent most of the time at high revs on his falie. The rear wing of the new 911 GT3 has also spent more than 160 hours in the wind tunnel and the car itself has passed some 600 emissions tests.
Porsche 911 GT3 in full on the Nardo test track
But the most interesting thing is the test that Porsche did on the Nardo circuit. On the huge circuit there, a driver has driven the new 911 GT3 around at 300 km / h for more than 17 hours. The top speed of the car is 320 km / h, so that’s almost full for more than 17 hours. In that time, the 911 GT3 has traveled 5000 kilometers. It was only stopped to refuel quickly and to change the driver every now and then. The pressure on the engine, the chassis, the body must have been enormous. But the Porsche apparently did without problems.
