But they're greeeeeener!!!! Shock, horror.
My gripe with everything in the Auto world isn't the rules they make, as such, it's the moving of goalposts. Buy diesel, it's greener. Now don't, we're banning them.
Whole engines, drivetrains, platforms etc have very short lifespans these days. Partly from higher pedantic standards of Motoring Journalists and partly because of ever-more stringent legislation. What is green about completely re-designing a whole engine once every 5 years vs eg: the CIH straight 6 used by Opel in the late 60s right up until the end of Carlton/Senny days in 1994. (and it was, of course legislation that eventually killed that powerplant off replaced by an engine which is, let's make no bones, less tuneable, more fragile, harder to service and only produced about the same power/torque figures relative to displacement)
Green is good. It is, of course it is, it's our only planet. I'm just one of those people who feel that some clever sod high up has managed to train a generation that it's better to buy a new thing once every few mins that's got 'green' credentials, than once thing, look after it, and keep it until it breaks/a lifetime.
