There is a rule in this hobby that every step up in performance costs you more to run. E85 breaks it.
On supported BMW platforms we build the calibration specifically around E85, and the fuel does the rest. Better knock resistance and a cooler charge mean more power and sharper throttle everywhere in the rev range, not just at the top. The part that makes it livable day to day is our full-time closed loop adaptive calibration, which reads the ethanol content and adjusts on its own, so a fill-up that varies from the last one does not send you back for a retune.
No extra hardware, no compromises, and usually a lower number on the pump than premium. Cheap fuel, premium performance.
