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...

But it did. Must be the advantage the turbo offers the Cummins, since the test was conducted in Colorado. The Cummins took 15 or 16 seconds, and the Tundra took 19+.
I saw the comparison on "The fast lane truck" YouTube channel. They also test the new 385hp/850tq Cummins towing a big load up to the Eisenhower tunnel, but so far, they have nothing to compare it to. Cool channel though.

After all the crying and tantrums, the bottom line is, it's still horsepower and diesels make more of it. At 2100rpm torque converter stall speed, the 6.7L Cummins is producing about 320hp at WOT from a dead stop and climbs from there. The Tundra as well as my less powerful 5.4L is lucky to push 140hp at it's 2100rpm torque converter stall speed so launch is going to be much slower at WOT than the Cummins. So while on the engine dyno and manufacturers' brochures they taught the same hp, on the track or up the hill from a stop, the Cummins makes more horsepower, the rate at which work is done. It's horsepower.
