There are very few places where you can really put a high-performance car through its paces. While we do, occasionally, test cars, we still wish we could be part of the AutoTopNL team and have quick access to the unrestricted sections of the German Autobahn. This time, the car that gets to be driven flat out is a McLaren GT that has been “slightly” modified. The GT is currently McLaren’s most practical and luxurious model, but as you will see, it’s more than capable of soiling the underwear of those who are uninitiated.

Adding to the luxurious aspect of the car is the nice spec of Storm Grey exterior color paired with a Saddle Tan interior. The car also provides 14.83 cubic feet (420 liters) of luggage space, which makes it one of the most practical high-performance cars ever made, with more capacity than a lot of hatchbacks. As for the engine, it’s a 4.0-liter twin-turbo V-8 with a flat-plane crankshaft. In stock form, it develops 620 horsepower at 7,500 RPM and 465 pound-feet (630 Nm) at 5,500 to 6,500 RPM.

While we are not being told what the modifications are, we have some impressive numbers. The 4.0-liter twin-turbo V-8 now pushes 770 horsepower and 728 pound-feet (987 Nm). While the stock, 3.2-second 0 to 62 mph (100 km/h) time is just as dependent on traction as it is on power, the new output allows the McLaren GT to reach a theoretical top speed of over 217 mph (350 km/h), as long as the gearing allows it.

As always, high-grade measuring equipment was used for determining some of the performance figures. The best 0 to 62 mph (100 km/h) time managed was 3.31 seconds while the best 100 to 200 km/h (62 to 124 mph) time was 5.21 seconds, which is slightly better than the 802-horsepower, supercharged Audi R8 by MTM that AutoTopNL drove a while back. As for how fast the car went, you’ll have to watch the video, but we will say that 200 mph (322 km/h) proved incredibly easy for this mildly-modified McLaren GT.
