IndyCar mandates twin-turbo engines for 2014


IndyCar announced Thursday that all engines supplied to IZOD IndyCar Series teams will utilize only twin turbocharger systems beginning with the 2014 season.

The decision, which was confirmed following a meeting the series’ Engine Committee meeting, is intended to further strengthen engine parity. It also dovetails with the manufacturers’ first homologation update cycle for the 2.2-liter, direct-injected V6 engines supplied by Chevrolet and Honda.

“In an effort for parity throughout the turbocharger range, mandating only a twin-turbo system simplifies our efforts to ensure even closer competition,” said Derrick Walker, IndyCar’s president of competition and operations. “Both manufacturers displayed a willingness to use a common turbo spec for 2014, so it made sense to mandate a twin turbocharger that maintains the performance we’ve come to expect while keeping the technology relevant to the automotive industry.”

Engine manufacturer competition returned to the IZOD IndyCar Series in 2012. Chevrolet re-entered the series with a twin-turbocharged engine through technical partner Ilmor Engineering. Honda, which was the sole engine supplier from 2006-’11, opted for a single turbocharger for the engine designed and built by Honda Performance Development.
