I don't put tigers in my tank. Exxon pulled some really nasty stuff on me some years back and I'll walk 10 miles to the next fuel stop rather than give them any business.
As for that other tiger, it was heavily armoured and heavily armed. The key word is heavy. With pretty much the same engine as the panzer, it couldn't keep up with its own smoke. The tank that Chrysler built with a 30 cylinder flathead based on the Windsor 6 could easily outrun one.
