The sound of silence-redux

SAN FRANCISCO–During the first half of our around-the-country drive in the Chevy Volt, the first conversations started stirring over one of the greatest features of electric and hybrid-electric vehicles: How quiet they are. Problem is, they’re apparently too quiet, at least for the National Highway Transportation Safety Administration. Last week, NHTSA proposed adding sounds to EV and PHEVs running below

One engineer’s experience in the Volt

Steve Leibson, longtime industry editor and engineer, got a chance this summer to tool around in the Silicon Valley in a Chevy Volt.  It's always good to get a different perspective, but Leibson's over three days tracks ours over 12 months.  He writes: "Quite simply, it drives like a smooth, well-bred car and it’s clear that GM engineers worked really


A “hybrid for all?”

Paris-based Valeo SA has an idea it hopes will help bring down the cost of hybrid car technology. Valeo has developed an electrification solution for the powertrain, Hybrid4All, which enables car manufacturers to turn a traditional engine –diesel or gasoline – into a hybrid engine, at an affordable price by using simple and standardized components. Valeo claimed the “Hybrid4All” architecture is
