Diesel vs gas......................

My '03 Cummins powered Ram advertised 250hp and 460 ft/lbs of torque. My '05 Hemi powered duplicate advertised 345hp and 365 ft/lbs of torque. The Hemi's easily out towed the Cummins. With horsepower, through gearing you can make torque. Without horsepower, you'll likely be reducing torque through O/D ratios just to make speed. Horsepower, the rate at which you apply torque. The Cummins had to run in O/D at interstate speeds. 460 ft/lbs through O/D's .69:1 ratio reduced driveshaft torque to 317 ft/lbs of torque. The Hemi's ability to rev allows it to run in direct and even second at peak torque rpm. 365 through second gear's 1.67 ratio puts 609 ft/lbs of torque to the drive shaft. So you can say it's all torque if you want to. The higher horsepower engine puts more torque to the drive shaft.
