Even a Stirling needs a heat sink. Since the heat rejection will presumably be at a lower delta-T the "radiator" would have to be even bigger.

Stirlings are awfully heavy/bulky for the power you get. They may be of value in stationary or even marine applications, but I doubt they would be worth the space/weight/cost on a land vehicle that rarely operates at over 50% of rated power.

Again, a technology that has not been widely used for good reason.
