Comments on: Protean In-Wheel Motors Could Up Hybrid Efficiency By 300 Percent http://inhabitat.com/protean-in-wheel-motors-could-improve-hybrid-efficiency-by-300-percent/ Green design & eco innovation for a better world Sat, 18 May 2013 14:21:36 +0000 hourly 1 http://wordpress.org/?v=abc By: tahrey http://inhabitat.com/protean-in-wheel-motors-could-improve-hybrid-efficiency-by-300-percent/comment-page-1/#comment-377574 tahrey Mon, 12 Mar 2012 14:22:16 +0000 http://inhabitat.com/?p=283550#comment-377574 Wait, so are they saying that current hybrids are, at best, 25% efficient, even in EV mode? The figures here are a bit iffy. If instead the claim is that they ran a normal Vivaro and a hybrid-boosted one through a normal euro fuel consumption test schema and the latter was 3x more frugal, then DUHHHHHH. Though that in itself is rather debateable with commercial vehicle diesel motors being in the 30-40 percent chemical-to-kinetic energy conversion efficiency range... If the source electricity came from some kind of futuristic 99% efficient diesel turbine generator, then the electric motors + drive electronics + charge system would still be managing a minimum 90 (and max 120!) percent themselves.
