V8 Supercars has moved to allay fears that the introduction of V6 turbo engines under its Gen2 regulations will decrease the category’s aural spectacle.

The draft homologation guidelines recently released to teams and manufacturers includes a minimum 85 dBA requirement for all engines.

The minimum joins the pre-existing 95 dBA maximum, in place due to environmental restrictions.

V8 Supercars marketing director John Casey says that the category is determined not to let any element of its on track product be diminished with the move to Gen2.

“I think everyone will pretty much drop into there anyway but, if they don’t, they’re going to have to find a way of making their engines louder,” Casey told Speedcafe.com.

“How they achieve it is up to them, but our intention is not to take that dimension of the experience away. If they don’t reach the minimum, they don’t run.

“The key hallmarks of our racing are ‘fast, loud and close’ and we won’t be compromising any of those with Gen2.”

Although noise levels will be mandated, whether the sound that the new generation engines produce will be popular with the existing V8 fans remain to be seen.

“You can make a V6 sound pretty good,” Prodrive team principal Tim Edwards told Speedcafe.com.

“You can have a V6 and a V8 roar down the street and most people wouldn’t actually be able to tell the difference.”
