I'm skeptical because most cars are much too low on load on the bsfc chart because they are overpowered. adding a bunch of drag (load) should bring it back towards the "sweet" spot, though total consumption still goes up. Even with enrichment, it is usually better to have too much load than too little.
so, if it had a saturn engine
, if the thing makes enough hp at 2500 rpm and 124.8nm to keep moving then it would be a real good match.
