The SKYACTIV family of engines delivers greater fuel economy and fewer emissions in a lightweight, responsive design. Every time a SKYACTIV engine is fired up, an immediate connection between vehicle and driver occurs.

The SKYACTIV-G 2.5 T is the first turbocharged engine in the SKYACTIV-G series. By succeeding the advanced combustion technology and the low resistance structure from the previous SKYACTIV-G series, this new engine provides exceptional acceleration performance. In order to stabilize the combustion at all rpm ranges, optimal control of water temperature is essential. The water jacket spacer inside the engine block, reduces heat loss to the coolant, thus improving both fuel efficiency and environmental performance.

A whole new turbo system, “Dynamic Pressure Turbo” has been implemented. At low rpms, the volume of the exhaust ports is reduced by closing a series of valves located just before the turbine that drivers the turbocharger. This results in solving the turbo-lag problem. The cylinder’s charging efficiency is improved by the scavenging effect, caused by the 4-3-1 exhaust manifold. Also, exhaust gas is supplied to the turbine more efficiently by suppressing the exhaust interference. By extracting the full potential of the turbo system, the engine produces a linear response with great amount of torque at all rpm ranges. The use of cooled Exhaust Gas Recirculation (EGR) helps prevent knocking and lower exhaust gas temperature, improving fuel efficiency throughout the entire rpm range.

Overall, our patented Dynamic Pressure Turbo is crafted to give you a higher level of power at lower levels of rpm with no lag, which means you get a smooth, powerful ride with superb fuel economy. The all-new SKYACTIV-G 2.5 T, drives Mazda’s “Celebrate Driving” experience and “Superior Environmental Performance” to the next level.

Now available in – 2018 Mazda6 and 2018 Mazda CX-9.
