As Rob noticed, many new cars have auto start-stop. My turbodiesel has insulation all around the cat, so killing the engine for 30 seconds at a red light won't cool it too much.
On the other hand, even without engine-off my hypermiling has brought the engine temps even lower than last year, and this is with a grille block. I guess this means I've increased efficiency?
