To squeeze even more driving pleasure out of every drop, the High Precision Injection (HPI) controls the fuel-air mix with absolute precision. The dosage of the fuel injected is precisely ensured by the piezo injectors with only part of the combustion chamber being filled under lower partial loads. Thanks to the Twin Scroll Turbo with Twin Scroll turbochargers as well as the compact construction of the engine, performance has been optimised to deliver more power on less fuel and fewer emissions.
