Go-Ahead Group

Go-Ahead is one of the UK’s leading providers of passenger transport, with over one billion passenger journeys taken each year on its bus and rail services. Williams Hybrid Power, a sub division of Williams Advanced Engineering until its sale to GKN in April 2014, has worked closely with Go-Ahead to develop and produce six prototype buses with a retrofitted Gyrodrive® hybrid flywheel system, providing electro mechanical energy to drive the bus and deliver substantial improvements to fuel economy and reduce CO2 emissions.

Speaking about the collaboration Phil Margrave, Go-Ahead’s Group Engineering Director, said; ‘The fuel consumption savings being predicted are attractive even at the lower estimates of around 10 – 15%…the price of fuel is what’s driving interest in this now. If the payback can be shown to be under 5 years, we might even retrofit flywheels on buses that are already ten years old."
