The 2015 Detroit NAIAS Auto Show happened at a slightly awkward time, with crashing oil prices and corresponding low fuel costs taking the edge off consumers' desire for efficient and green car options. Still, there were plenty of fuel cell, electric and plug-in hybrid vehicles on show, as well as a cavalcade of giant American trucks and several truly stunning sports and supercar launches.
