I have noticed that Honda are going very green of late, with S2000 production stopping, dropping out of F1, hydrogen fuelled cars etc. With 'peak oil' due very soon its hard for car makers to justify bringing out 'sport' models of 'green' cars.
There is legislation in place to cap the 'average CO2 footprint' of car companies across their range, which is why LandRover are in such a pickle, they don't produce small vehicles to offset their gas guzzlers. I suspect that this 'average CO2' cap is being reduced every year as well.
