Porsche Made Public Their New 911 GT3's Performances At 186 MPH For 3,100 Miles Non-Stop!

Testing a car's character on the roads isn't something that it's done in one round. Different roads, weather resistance, race track, different obstacles are just a few tests done to see what a car can do in extreme conditions. Porsche's tests for its car are very methodical one and they're going on the full length with them. Recently they tested the 911 GT3 resistance at 186 MPH for 3,100 miles non-stop! Crazy, right?
There's also a plan to prepare the 911 GT3 for the road test, Porsche's team of engineers really went extreme testing the car. This time they performed a test that consisted of a 5,000 km (3,106-mile) test at the Nardo Italian test track. All the 3,106 miles were a sum of constant rounds on the 23 km (14-mile) circular track owned by Porsche. Unwillingly, at this pace, even the race track passed her own resistance testing.
After Porsche invested so much the engine development technology, it's normal to be sure that the 911 GT3’s engine is durable enough for the road. The test consisted mainly, of driving the car at a constant speed of 186 mph (300 km/h) for the whole distance, stopping only for fuel. The 911 GT3 has a developed similar 911 GT3 R Cup car - the 4.0-liter engine with VarioCam technology, wide connecting-rod bearings, plasma coated cylinder liners, and much more. The engine’s test revealed a great performance and ensured that the flat-six can get to its 9,000 RPM redline reliably.
Usually, a naturally aspirated, six-cylinder engine makes 502 horsepower, nearly 10 more than the outgoing model. Thomas Mader, Project Manager GT Road Car Engines stated that “In total, the engine in the new GT3 ran for more than 22,000 hours on the test rig. During testing, we repeatedly simulated typical circuit profiles and ran the engine at full throttle for a very high proportion of the time,” said Thomas Mader.
There's more than racing technology to ensure 16 hours straight for the 911 GT3 run at 186 mph. It includes the aerodynamic tricks and the swan neck mounts used on the rear spoiler - both holding the rear wing from above, allowing the air to pass over its bottom as undisturbed as possible.
According to aerodynamics engineer Mathias Roll, they developed the aerodynamics of the new 911 GT3 in around 700 simulations and spent more than160 hours fine-tuning the car in the wind tunnel. “The new 911 GT3 generates 50 percent more downforce than its predecessor at 200 km/h just in the ex-works setting,” said Roll. Indeed, the race track was a great point of view and inspiration in creating such a performant hypercar.
