A minimum fuel intake has been a staple of the Supercars rulebook across the Car of the Future era, initially introduced to offset fuel economy concerns when the likes of Nissan and Volvo joined the series.

As it stands the rule requires teams to take run at least 140 litres of fuel into the 111-litre tanks during any race with two mandatory pitstops.

The rule proved decisive during last Saturday’s opener in Adelaide, where Walkinshaw Andretti United was able to satisfy the fuel drop during a safety car and could two-stop when most others needed three.

That helped Chaz Mostert and Nick Percat to a one-two finish.

The fuel drop has, from a technical perspective, become largely irrelevant in the past few years with the Volvos and Nissans disappearing from Supercars.

And while there will be different types of engines for Gen3, with the Mustang powered by a quad-cam motor and the Camaro a pushrod motor, the cars will have a significantly larger fuel cell with a volume of over 130 litres.

However Supercars still has no plans on dumping the minimum drop rule in at least the short term.

That, according to Head of Motorsport Adrian Burgess, is down to both wanting to properly assess consumption parity, and keep the strategic options provided by the drop open.

“First of all, this is a byproduct of the homologation process – making sure we’ve got fuel consumption, car-to-car, to a tolerance where you could get rid of the notion if you wanted…
