Horsepower is horsepower?
If that theory is true (in real circumstances), then a 385hp 6.7L Cummins diesel shouldn't spank a 381hp Toyota Tundra when both are tested 0-60 towing a 5740# boat. But it did. Must be the adva...

Actual usable output with proper gearing
Tundra 275hp @3600 > 381hp at 5600rpm
Cummins 6.7 275hp @ 1700 > 385@2800rpm.
At lower elevations they should be very similar. The cummins earlier torque should initially counteract its beaver weight, but in at longer pull, it would essentially come down to which vehicle has the ability to run at our nearest to its power peak.
EDIT - Isn't it astounding that the gas engine, if geared correctly, has EXACTLY the same usable power, over a WIDER rpm range than the the TURBO Cummins?
Someone check my math....
