http://www.gizmag.com It seems that the lessons learned in developing a mechanical KERS system for F1 may yet hold the key to a low-cost, high-efficiency hybrid system particularly suited for the stop-start patterns of buses, which are quite similar to the distances between capturing and delivering energy of those of a race car. Torotrak will deliver a paper at the SAE Commercial Vehicle Congress in Illinois next week showing how flywheel KERS for buses can offer more than 30 percent fuel saving over the London bus test cycle, yet package around an existing transmission.en gizmag.com http://www.gizmag.com/torotrak-mechanical-kers-system-for-buses/13023/#comment-20974 http://www.gizmag.com/torotrak-mechanical-kers-system-for-buses/13023/#comment-20974 Thu, 29 Apr 2010 05:22:29 -0500 http://www.gizmag.com/torotrak-mechanical-kers-system-for-buses/13023/#comment-9085 http://www.gizmag.com/torotrak-mechanical-kers-system-for-buses/13023/#comment-9085 Mon, 05 Oct 2009 09:58:52 -0500
