How to do a 300mph+ top speed run: Bugatti's Andy Wallace reveals his secrets
Supercars Andy Wallace has many Bugatti accolades to his name, here's what the king of speed has taught us Skip 4 photos in the image carousel and continue reading Only one man has blasted past the magical 300mph barrier in a production car, lived to tell the tale and kept his lunch down. Andy Wallace is a titan of top speed runs, a vanquisher of vmax and one of the nicest blokes you'll ever meet. Here's everything he's taught us. 1. Jump to it Suppose you could call this bit 'expect the unexpected' because Ehra-Lessien (the venue for the Chiron Super Sport's 304.8mph record run) was 'repaved halfway round the bit where you do vmax, and there's a join between the new surface and the old bit', Andy explains. 'I was coming back and saying to the engineers 'Oh, the car's quite stable over the jump' and they were getting quite annoyed, saying 'What jump are you on about? It can't be off the ground'. They looked at the data and came back saying 'Oh, you're right – it's a jump'. That was at about 270mph.'

The gyroscopic mayhem caused by 4,100rpm wheels locks out the front steering geometry and scrambles the steering's ability to self-centre. Apply too much lock and you might not be able to pull it back straight. To be fair, aeroplanes normally fly at this kind of speed, so you'd expect some unusual handling traits. 3. Fit for purpose The record car was no ordinary Chiron. The Super Sport 300+ Prototype was 250mm longer with a significantly lower ride height to reduce drag. At the rear, the longtail had a reduced cross section (to aid aero and minimise drag), while the rear wing and air brake were removed, replaced with a static unit. You might like The Guinness speed record rules are as follows. The car must achieve the speed in two directions on the same road within 60 minutes, with the average of the two speeds the result. Andy only ran the speed in one direction. Bugatti says the main reason for this is that, after decades of cars pounding over its surface in the clockwise direction, the tarmac structure has rolled that way. Run it in the opposite direction, and you're working against the grain, causing huge heat build up in the tyres. 5. Balance is everything While you want to keep the car on the ground, you can't just throw downforce at it. Downforce means drag, which requires more power, and greater heat through the tyres. What you want is a balance between two tonnes of lift and two tonnes of negative lift (downforce); in essence, four tonnes of force trying to rip the chassis in two. However, if balanced properly, vmax sees merely the static weight of the car keeping it on the ground, reducing tyre load, tyre heat and the chances of a crash.

Bugatti Chiron Super Sport '55 1 of 1' Spotted in Dubai
Read the full story on Modern Car Collector One of the rarest Bugattis in existence has surfaced in the United Arab Emirates, as the Chiron Super Sport '55 1 of 1' was recently spotted outside the Kempinski Central Avenue hotel. This ultra-exclusive hypercar, crafted by Bugatti Sur Mesure, was commissioned for a client in the Middle East and is a modern tribute to the iconic 1930 Type 55 Super Sport designed by Jean Bugatti. Originally unveiled last year, the '55 1 of 1' stands apart with a striking yellow-and-black exterior, a color scheme that mirrors the original Type 55. The car also features a hand-applied "55" graphic on the front fenders, a nod to its inspiration. A unique detail is the underside of the rear wing, painted in bright yellow and displaying the number '55', ensuring that even at high speeds, the tribute remains visible. Inside, the Chiron Super Sport maintains its bespoke craftsmanship, with a black leather interior accented by hand-stitched yellow detailing that complements its striking exterior. Every element, from the dashboard to the seats, has been meticulously tailored to match the car's historic theme while preserving Bugatti's signature luxury. Powered by Bugatti's quad-turbocharged 8.0-liter W16 engine, the Chiron Super Sport produces 1,578 horsepower, making it one of the fastest production cars in the world. With a top speed of 273 mph (440 km/h) and a 0-60 mph sprint in just 2.4 seconds, this bespoke hypercar combines elite performance with automotive artistry. Spotted by @skajll_carspotting, the '55 1 of 1' drew attention from enthusiasts and passersby, reinforcing Dubai's reputation as a hub for hypercars and one-off automotive masterpieces. With such exclusivity and heritage, the Chiron Super Sport '55 1 of 1' stands as a rolling tribute to Bugatti's rich legacy while pushing the boundaries of modern performance.
