Mazda says it has enhanced its SKYACTIV-G engine series with a range-topping SKYACTIV-G 2.5T. This 2.5-liter direct-injection turbocharged gasoline engine powers the new CX-9 midsize three-row crossover SUV that will go on sale starting from North America in spring 2016.
Based on the naturally aspirated SKYACTIV-G 2.5 featured in the Mazda6 (known as Atenza in Japan), SKYACTIV-G 2.5T is the first turbocharged engine in the SKYACTIV-G series. Mazda says it delivers exceptional fuel economy, excellent response without turbo lag, and "linear and powerful acceleration in the low- to mid-rpm range where CX-9 drivers spend the vast majority of their time".
SKYACTIV-G 2.5T features a "Dynamic Pressure Turbo", claimed to be the world's first turbocharging system that can vary the degree of exhaust pulsation depending on engine speed, and a "cooled exhaust gas recirculation (EGR) system that allows the engine to maintain the ideal air-fuel ratio".
