Yeah anything French people organize will have some eccentricity. When they interviewed Robbie the night before showing off his Ctis he even said I can't show everything there is secret stuff in there. Perhaps the tube to the intake was not there in previous years or at inspection??
Hunner the Dakar hummer has its engine in the back of a full tube framed buggy. Slightly modified from stock...there are some fun dyno run videos on YouTube.
Was fun watching them do trail side repair after ripping up all the suspension on right side after hitting a rock while driving too aggressively off course. But it's sad he's back to 25th now. No chance of glory now disqualification or not.
