The Bugatti Veyron can fly down highways at more than 250 mph, but for those who shell out more than $1 million for the fastest street-legal car, its ability to stop can’t be overlooked. Braking from top speed to a standstill in 10 sec requires more than its eight titanium brake pistons. Its rear wing acts as a brake, using two MTS Systems Corp. magnetostrictive position sensors to adjust the wing’s height, with another maximizing angular adjustments for the air brake. The wing raises and assumes a 55 degree angle in just 0.4 sec. Sensors from MTS, based in Cary, NC, are housed in the hydraulic piston that moves the wing.
