The Surge doesn't have near the peak torque that the regular Fuel does, but there's more to it than just that. It drives screws up to 4" just as well as my M18 One-Key, and with its sustained torque, will try to drive smaller ones right through 2x framing, head and all, if you let it. As much as anything, I use my M18 for boring framing with Bosch Daredevils, and the Surge would go out on overload with them over 1/2" when I tried it for giggles. For that reason, my Surge doesn't come out much, but if I were primarily driving fasteners, it would see much more use.
