I must grudgingly point out that there ARE some very viable reasons for the differences in US and European racing. I'm a diehard road-racing, anti-NASCAR fan, but it doesn't change the fact that they're right in much of their approach. It's also true that US automakers DO have a presence in the high-tech fields of racing, but you get the impression it's not as serious as their competitors', so perhaps they don't learn as much from it.
Saaby...interesting to note that I think one of GM's main reasons for acquiring SAAB was to gain their engineering expertise. GM has always had difficulty with 4-cylinder motors...SAAB-designed and influenced 4-cylinders are supposed to start appearing in a lot of GM vehicles. And the platform the new 9-3 is based on, heavily influenced by SAAB, will also be the basis for lots of GM cars. Those Swedes must know what they're doing, since the same thing is happening to the Taurus...a Volvo platform will be its basis.
Back to the concept of missing a market...I think GM would be passing upgraded efficiency costs to us, but is sticking hard and fast to the business law of "keep costs down." A more expensive car either cuts directly into their profits, if they keep the price the same, or indirectly (if they raise the price) by selling fewer overall units. Presumably, they're convinced that however they do it, these efficiency upgrades will cost 'em profit. I think history has shown otherwise, but maybe it's not quite that simple, and the kind of efficiencies we're talking about wanting are pretty much uncharted territory.
