And less torque at a certain RPM? So drop the trans a gear and use the torque the engine produces. I get worse gas mileage if I keep my truck in 6th gear, below usable torque. I drop it to 5th and my engine works less and my gas mileage goes up. Amazing.
Peak torque (420lbs) on the ecoboost is 2500rpms. Peak torque on the 6.2l (405lbs) is at 4500 rpms. Peak torque on the 5.7L (401lbs) is at 3600rpms.
I don't ever tow more than 2800 rpms and that's only on rolling hills with a side wind.
You can't compare peak torque numbers only. Let's see some dynos and torque numbers at 1500, 2000, 2500, 3000, 3500 RPMs. Usable RPM ranges. Boosting peak torque @ 2500 rpms, when it may be 70% at 2000 doesn't do any good. Whereas the larger engines may peak at 3-4K rpms, but hold 90% of it at 2000 rpms.
