At sea level a 2-valve Ford V10 puts out the same amount of power at its rated maximum torque than does this MH's diesel. At maximum torque they are both putting out the same +/- 260 HP (assuming 1,700 RPMs for diesel).

A 3-valve V10 has a little more torque at lower RPMs but works out very similar in available power to propel the MH at its maximum torque rating.

Torque alone doesn't say much because if you want to accelerate or go up a hill faster, you simply step on throttle and the transmission will downshift to get engine running much closer to maximum horsepower.

It's interesting that new Ford SuperDuty V8 puts out maximum torque of 430 lb-ft at 3,800 RPMs, which works out to 310 HP. At sea level that's more power (at rated maximum torque) than either the V10s or this Cummins diesel.

I'm not trying to compare these engines on equal basis because the Cummins is built heavier for durability, but when it comes to acceleration or hill climbing, power is power, which is why diesels may feel fast but are often slower.

Compared to an Axis weighing roughly 1/3 as much, this diesel MH is going to accelerate and climb very slowly. My guess is that most DP buyers don't care about speed all that much. But if they did, they should look for greater power to weight.
