Understanding HP and Torque
I thought of this question to myself. My 4.3L V6 Silverado has 195 HP and 260 ft·lb of Torque. Does that mean that any engine with higher specs could tow more weight than me and drive faster?
For example, a sporty car like a BMW has more HP and more Torque than my V6 Silverado, but could you tow easier/better with the BMW or my truck? Obviously the BMW is faster than my truck even if it had lower numbers than my truck.

i acually have thought about this to. this is how i figure it. those cars werent designed to tow. the chassis, suspension, etc, were designed to be sport cars so you wouldnt want to tow with them while trucks are built to be tough and tow and haul. those cars also reach there power band at much higher RPM than truck motors, which gain there power in very low RPMs because when they do haul they need that low end gruntPETE

Some cars even have 1000HP but could it really outperform a truck (towing wise)?

To answer to engine spec question, I say yes. If you put the Beamer motor in the same truck, it would tow more, faster. Peak HP and Torque may be at different RPMs. But once you get to the right RPMs, you're off to the races. As far as a BMW towing more than your truck, I think it would, right up to the point where the transmission falls out and the rear end gets ripped out from under the rear of the car. Apples and Oranges.
