In addition to making safety changes for such high speeds, companies changed the car's bodywork to improve aerodynamics. The tires were also specially developed by Michelin, which makes the tires for regular Chiron cars as well. The tires are still legal for road use, but they were reinforced to withstand these extremely high speeds.
"It is inconceivable that a car would be able to do this. But Chiron was well prepared, and I felt very safe – even in these high speed areas , "Wallace said in a statement.
The standard Bugatti Chiron is limited, using electronics on board, to a top speed of 261 miles per hour. Bugatti has never said how fast an unmodified car could go without the electronic limiter. The reason for that, company executives have said before, is that they were unsure that the tires could safely withstand higher speeds.
After setting this record, the company has nothing left to prove in terms of speed, Bugatti President Stephan Winkelmann said.
"Our goal was to be the first manufacturer ever to reach the magical 300-mile hour. We have now achieved this – to make ourselves, the whole team and myself, incredibly proud, " said Winkelmann in a statement. "We have shown several times that we are building the fastest cars in the world. In the future, we will focus on other areas."
