My initial guess was water or oil, maybe they are toying with the idea of radiators like the S10 to make room for the heavy duty fuel tanks. Rc 8 fuel consumption figures are not great and that runs with gearing that would push 290kmh...don't think you'd want to be on that doing those speeds...however the acceleration to 240kmh on the dirt would be mind blowing!
