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...

The day we can have generator-motor drivetrains like locomotives, is the day this diesel vs gas hp vs torque argument will end.
Beauty of a generator: it doesn't care HOW you generate the hp, 1 hp is 1 hp.
Turbines with no torque and 30,000 rpm, windmills with earth turning torque and no rpm, gas, diesel, nuclear reactor, you name a power source, and it has powered a generator at one time or another.
In the end, your towing power solely depends on your traction motors at each wheel / axle, and it only needs hp fed to it (in the form of amps and voltage).
Roy, thanks for you post above ... another island of reason in the chaotic Diesel Versus Gas sea!
Somewhat related to your comments ... I recently read that some European manufacturer was finally going to introduce, IMHO, the "done right" hybrid automobile.
My very general summary of it's technology goes something like this:
- It has the expected state of the art electrical motor and battery drive system with electronic controls ... i.e. like Prius does.
- HOWEVER it's secondary backup small fossil fueled engine is DIESEL, instead of gasoline ... for the ultimate is stingy fossel fuel consumption when exceeding the range of the electric drive system and in topping up the batteries whenever they run low.
P.S. I'm an advocate of diesel engines for applications such as the above, and in electrically driven locomotives, and in big rigs -> just not in applications such as the power source in small and light trucks where low purchase cost, low maintenance costs, low weight, supreme quietness, superb drivability, and broadest fuel availability are top priority.
