Max from the YouTube channel AutoTopNL did a speed test with a BMW 7 Series xDrive. Before hitting the speed limitless autobahn in Germany, he modified his BMW, a 750i with a V8 engine.
He called a specialist company to remove the speed limiter set at 250 km/h. He mentions that it was quite a complicated operation because the car had the latest software.
The driver mentions that he chose a Sunday morning to do this test because the highway was freer, truck drivers have Sundays off in Germany. He also mentions using two phones and a speedometer app with a head-up display setting to show the car’s speed in miles per hour and kilometers per hour.
Before driving off he switches the car into sport mode, but not before checking the high-speed tire pressures, setting them to 3.2 on the front and 3.3 on the rear. To ensure that the edge of the hatch does not affect the aerodynamics of the car Max taped it.
During the test he manages to reach the fabulous speed of 321 km/h, according to the application installed on the smartphone. It would be 71 km more than what was declared in the data sheet.
