HIROSHIMA, Japan—Mazda Motor Corporation has enhanced its SKYACTIV-G engine series with the range-topping SKYACTIV-G 2.5T. This 2.5-liter direct-injection turbocharged gasoline engine powers the all-new CX-9 midsize three-row crossover SUV that will go on sale starting from North America in spring 2016.
The SKYACTIV engine series aims to offer customers a combination of outstanding fuel economy and excellent dynamic performance in everyday driving situations. Mazda's development philosophy is to offer this combination across all vehicle lines, using the most appropriate engine displacement and simplest configuration of technologies for a given vehicle size. Developed in line with this philosophy and 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. It delivers exceptional catalog and real-world fuel economy, excellent response without turbo lag,*1 and linear and powerful acceleration in the low- to mid-rpm range where CX-9 drivers spend the vast majority of their time.*2 Maximum torque is 310 ft-lb, comparable with a naturally aspirated 4-liter gasoline engine.
Traditionally, turbocharged engines have suffered from poor dynamic performance at low rpms, including turbo lag, and disappointing real-world fuel economy. SKYACTIV-G 2.5T overcomes these problems with the Dynamic Pressure Turbo, 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*3 (λ=1) over a wider output range.
Mazda will continue to offer all customers driving pleasure and outstanding environmental performance through its SKYACTIV engines which aim to achieve the ideal in combustion. The company hopes to enrich people's lives and become a brand that maintains an emotional connection with customers.
