What does "loaded" mean anyway? Curb weight of 3674 plus a tank of gas would be an extra...200 lbs? So it seems a gross weight of 4800lbs would be the 200lbs of gas plus 5 adults in the car, or someone who weighed 200 lbs and loaded 800lbs of junk in the trunk. lol
I wouldn't base a race on gross weight. Hypothetically if the gas weight was the same per vehicle, I'd base it on the curb weight, plus the weight of the drivers.
That being said, the Sexima will still win hands down.
