The Cummins 5.0 V8 diesel "numbers" speak for themselves. In terms of raw torque (vs. 1/2 ton gas engines), I agree it's not a fair comparison--the Cummins 5.0 V8 comes out on top. You can play the HP card all day long, but big torque numbers at low RPM's is what makes for effortless towing in the realworld. Big HP numbers (relative to torque) require a lot of RPM's and constant transmission activity to maximize output---both distract from the ideal tow experience.

In the pickup market, yes only the EcoD. In the SUV market, there are many more to compare side by side with their gas engine options.

The Cummins 5.0 numbers do speak for themselves. They are low on HP compared to their competitive gas engine options. We can play the torque vs HP game all day, but the fact remains when you are full throttle under high load...just cause its a diesel doesn't mean its will hold under 2,000rpm where peak torque shows up.

You will be surprised to learn how high these diesels actually run when towing under stress. I suggest you pay closer attention...cause you are clearly missing this point.

ANY engine under "stress" or full throttle will be performing at the edge of its reliability/torque curve. What's your point?

My point: effortless, stress-free towing through the use of an engine that produces high torque at a very low RPM with minimal transmission activity, and minimal NVH. High HP numbers (relative to torque) can produce significant torque with proper gearing. However, the down side is high RPM's, constant transmission activity, and high NVH.

A diesel engine has its forte. So does a gas engine. There's a very good reason why you'll never see a diesel engine in an Indy 500 race car. There's also very good reason why you'll never see a 700 HP Indy 500 engine powering an 18-wheeler.
