For the very high temperatures involved I think a Stirling engine could easily reach double that, if not triple. Problem is it is mechanical and probably more expensive. Apparently BMV and GM are now both looking into generating energy from your hot exhaust gases using TEGs - see http://news.cnet.com/8301-11128_3-10013303-54.html?part=rss&subj=news&tag=2547-1_3-0-5 If you dig down into the comments you find that this article http://www.technologyreview.com/Energy/21125/ puts the potential efficiency of TEGs based on the new material at 10%.

You're still better off with a Stirling engine - I'm surprised no one has bolted one to a car exhaust yet - you could also pipe heart from the brakes too. Unlike the solar car roof it would probably generate enough power or direct cooling to run the AC.
