“We have to put a different fire bomb in them next year,” he noted.
“This year, we had to run two separate bombs, which was a bit of a pain, but there's going to be a single bomb coming back, which will need complete re-plumbing and then it'll sit down near the footwell.”
Why the change has been made is unknown, although the category moved to a new specification of fire bomb – or, more formally, fire suppression system – this year amid the changeover to Gen3 and a new, E75 blend of fuel.
Given that the Dunlop Super2 Series will also be switching to E75 during this off-season, after pushback over plans for a mid-season change of fuel spec, it seems likely that both competitions will run on the ‘Zero 275 Larger Bottle and Fitting Kit' which the second-tier squads were to have ordered for their Gen2 vehicles.
Re-plumbing a car for a new fire suppression system is a not insignificant exercise, with the engine needing to be removed.
However, as Jones outlines in his video, teams have been doing that for off-season service activities anyway.
Supercars ran on E85 for the 15 years until the end of the Gen2 era, with the 85 percent ethanol component produced from waste sugar cane production.
