First Merlin aircraft engines, now monstrous tank engines. Where does the madness end?!? And when do I get to drive?

These sorts of motors produce gobsmacking amounts of torque, but are relatively low on the hp scale, especially for their weight. It'll make a nice tractor pull rig (in fact, at least back in the early 80s, these sorts of motors were de rigueur at said pull events), but in a car? Not so much.

Still, I wouldn't turn down the keys.
