F-1’s Williams Makes Progress With Hybrid London Bus, CEO Says

Williams Grand Prix Holdings Plc, Formula One’s only publicly listed team, expects to start street testing of a hybrid London double-decker bus this year as it seeks a revenue boost from technological expertise, chief executive officer Alex Burns said.

The nine-time F-1 constructors’ champion and bus operator Go-Ahead Group Plc 14 months ago agreed to make six prototype vehicles with flywheels that recoup energy from braking, a system Williams developed for racing. Williams and Go-Ahead are testing one prototype off public roads that has shown “very promising” fuel saving, Burns said, without being more specific.
