Yeah, these are dumb. Due to traction, I'm sure my wife's '14 Hemi AWD Durango would likely win against my '15 4x4 Dually. Rear end just has a lot more traction due to the relative weight... not to mention the Hemi and that awesome 8-speed puts instant horsepower to the wheels. The one who gains forward momentum first, with the most traction wins these. It's all about having enough motor to overcome traction... anything past that is gravy.
