Haven't driven a 6.2 so i can't say. I've had similar motors in other GM vehicles and they're quite strong. I feel the Duramax is plenty at posted speeds, but once it's past 70 or so it's more leisurely. Hills are no problem either. None of the annoying shifting up and down to get up a grade like most smaller engines tend to do. If the 6.2 and Duramax went head to head I'd expect the diesel to hang in there in the 1/8th but by the 1/4 mile the 6.2 would be long gone. Maybe someone will try it sometime and we'll find out. For most uses the diesel is strong enough and the mileage is far better. For max performance the 6.2 is the way to go.
