AUDI R18 E-TRON QUATTRO WITH WILLIAMS HYBRID POWER FLYWHEEL CONTINUES WINNING STREAK IN WORLD ENDURANCE CHAMPIONSHIP
22 April 2013. The Audi R18 e-tron quattro, powered by Williams Hybrid Power’s electric flywheel hybrid system for the second year in a row, continued where it left off last season by clinching a dominant win in the first round of the 2013 F.I.A. World Endurance Championship.
The Audi number two car, driven by Allan McNish, Tom Kristensen and Loïc Duval, took the lead in the fifth hour of the race after 151 laps and eventually crossed the finish line with a 3.4-second advantage. The sister number one car, driven by Marcel Fässler, André Lotterer and Benoît Tréluyer completed Audi’s one-two. This result followed the one-two result in the non-championship Sebring 12 Hours in March. It also comes on the back of a dominant 2012 that saw the Audi R18 e-tron quattro become the first hybrid car to win Le Mans and ultimately clinch the World Endurance Championship.
Williams Hybrid Power’s flywheel energy storage system was first developed for the Williams F1 Team’s 2009 car, but has since become a race winning technology on the endurance racing circuit as well as non-motorsport applications such as buses and trams. The key benefits of the WHP system are a high power density and correspondingly low mass, the ability to continuously deep power cycle, high efficiency energy transfer to and from the e-storage, and an insusceptibility to performance or life degradation over a wide range of operating temperatures. These defining features are highly suited to endurance racing and have helped power the Audi R18 e-tron quattro to the top of the standings.
Ian Foley, Managing Director of Williams Hybrid Power, commented, "Williams Hybrid Power are pleased to be working with Audi Sport once again this year to supply our flywheel technology for the innovative hybrid system on the R18 e-tron quattro. We had a very successful 2012 and hopefully 2013 will see that success continue. We continue to bring our fuel saving technology into areas beyond motoracing such as public transport, but racing is a fantastic testing ground for our flywheel and it is a testament to the team at Williams that our system continues to perform at the highest level."
