I think the most impressive thing about Bentley’s high speed run over the Bonneville Salt Flats in 2012, where it maxxed out at 307 km/h, was the amount of preparation the car received.
However, as he pointed out, although cars traveling at high speed are a common sight at the Bonneville Salt Flats, Andy explained there was a lot more to the top-speed run than simply holding the accelerator to the floor.
While filming the high-speed run a helicopter unexpectedly moved position, creating a 100km/h cross-wind.
Helicopters have previously blown cars off course at Bonneville with disastrous effect, but there was no time for Andy to change course or brake.
“The Bentley twitched ever so slightly, maybe one degree, a tiny tweak of the steering wheel and it just kept going at 300km/h,” he said.
Andy explained that driving at high speeds on salt makes cars prone to oversteer and many land-speed cars can suddenly spin out without warning.
“Salt is a slippery surface. The coefficient of salt is about 0.5 – that’s about half what you get on dry tarmac. So it's just like driving fast on tarmac in the pouring rain!”
Andy Green is currently preparing for another tilt at the land speed record in 2016 and this time he wants to hit 1000mph!
