British pilot Andy Wallace watched with disbelief footage of himself reaching 304 miles per hour in a Bugatti Chiron. It looked quite easy like a video game but Wallace said it required months of preparation, endless testing of wind tunnels, the right tires and an overwhelming amount of tech.
The Bugatti Chiron Super Sport 300+ boasts of 16 cylinders, 4 turbo-chargers and 1,600 horsepower. Engineers developed the car with speed in mind and it can cruise faster than a small plane. Since Michelin was already making tires for the standard Chiron, they knew how to upgrade the Super Sport’s tires.
According to Benjamin Vilpert, a Michelin engineer, his team headed to Charlotte, North Carolina where their firm helps NASA test tires for the space shuttle. Michelin wanted to ensure that the tires it has developed for Wallace’s high speed run will pass all known boundaries. They learned the limits of the current tire and reinforced it with belt. They tested the tires after defining the right conditions.
Testing of the tires involved several computer simulations and high speed runs on a dynometer. Because technology was very precise, the Chiron never touched down in Charlotte. The Pilot Sport Cup 2 tires that were developed by Michelin were only mounted a week before testing started on the Ehra-Lessien track in Germany.
Bugatti was able to find out how the Chiron would handle as it approached and exceeded 300 miles per hour through computer simulations. Testing started in a wind tunnel that allowed speeds up to 65 yards per second. Since 149 yards per minute on the track must be covered, digital tools were used to fill the gap.
Digital tools helped the engineers in shaping the car’s aerodynamic profile including the extended rear end that will keep the car planted on its 4 wheels through the addition of drag. Wallace was confident because technology prepared the Chiron for the high speed run.
Even if you do not have a Buggati, you can buy brand new Michelin tires that are guaranteed free from defects. Because great emphasis is placed on precision, almost all popular tire designs are available to accommodate different needs.
