Why does the BMW M4 GT3 Evo have to compete with a new turbocharger this year via a re-homologation? BMW Motorsport Director Andreas Roos argued that the change in the car's fifth year of competition - the second with the Evo package - was due to costs. "The main reason was to get the costs down, because it is now 1:1 the production turbocharger as it is used everywhere in the M3 or M4," Roos said when asked by Motorsport-Total.com.
"That is nonsense," says a BMW insider who does not want to be named. "Of course the new turbo is cheaper, but the changeover cost at least a mid to high six-figure sum. For that amount of money, you could have given customers many turbochargers at a cheaper price."
