Porsche put the 992 GT3 through a brutal testing regime
Perfect example of why these cars should be driven
Normally when a car company tests a car they do 20 laps or so of the Nurburgring a day with 147 corners in each lap with a straight line in between those corners then the drivers go back to the pub for the evening. This includes braking, steering and the drivers sitting around doing nothing over lunch. Porsche is no normal car company though.
What they did was do 3,100 miles of the Nardo test track in Italy at 186mph in one day. This track doesn’t have 147 corners per lap: it is just one continuous corner. They did 16 hours of running continuously and only stopped for fuel or a driver change. It is a very similar regime to what they subject their GT race cars to.
The Nardo Ring: one continuous corner
The GT3 road car was actually developed alongside the 992 911 GT3 R and GT3 Cup cars and the engine is based off the engines in them. The only differences are the ECU mapping and the emissions filters so it is road legal and you have probably worked out by now that the engine was subjected to rigourous testing too.
The 4 litre Flat 6 that is in the GT3
The engine was subjected to 22,000 hours on the dyno and a lot of that time was simulating power used around race tracks including pit stops. This running was done for more than a few thousand customers who will probably lock it up in a glass box for 20 years. As I mentioned earlier this engine is extremely similar to the engine in the racing 992 911s so data collected on this also helps development in their racing progamme.
The average modern car is made with as few sharp changes in direction of metal on the exterior as possible to keep the drag low. With Porsche being a company made by winning in corners though the wind tunnel time acheived something far more impressive.
The 992 GT3 spent 160 hours in the wind tunnel with 700 different tracks simulated in there to optimise the airflow. After this they came to the conclusion that you can adjust the front splitter and rear wing into 4 different positions for each component and they can be adjusted seperately from each other for the perfect setup all-round for the driver. With the work in the wind tunnel they managed to extract 50%-150% more downforce out of the 992 GT3 than the 991.2 GT3 body could muster depending on if you want straight line speed or cornering grip out of your 992.
Does this prove anything useful?
Yes it does. It shows that driving them doesn’t do damage to the car(unless you crash so Richard Hammond shouldn’t buy one). For a 992 GT3 to be able to do 3,100 miles at 186mph in one day is impressive and tells the idiots who buy them that they should be driven and that they can handle it; even if it was on their own track to keep it away from wreckless peasants so they don’t crash.
So if you buy a 992 911 GT3 go and god damn drive it!
