Power is only part of the problem. No BS, what’s killing current trucks is the DPF system that the EPA mandated. In the test cell, and in the test trucks, no bullshit, we saw an AVERAGE drop of 45 to 50 percent in MPGs with the DPF, plus you have the urea cost. We bypassed the DPF on 4 of the 9 test trucks with the 6.7 HO, we saw 22-25 mpg unloaded, on each. Vs 14-16 on the 5 we left with the DPF. Towing was even worst. Heavy, we saw DPF trucks dropping to 7-9 mpg, same load(a bobcat skid steer) those 4 trucks we deleted averaged 12-15 over the exact same route.
