Really interesting video by TFL on 2016 CX-9 new Skyactiv 2.5L turbo engine.
New engine makes 250hp @ 310ft.lbs of torque.
Summary of video is;
o 13:1 reduced to 10.5:1 to run turbo
o water cooled EGR saves gas
o 250hp on 93, 225hp on 87 octane
o 310ftlb off the line
Mazda seems to always be on the leading edge, and the water cooled EGR is a good example. Turbos usually run rich when under boost to keep engine cool and wastes fuel, but Mazda found a way to run lean by water cooling EGR return gases.
Would be interesting if they offered this engine in a CX-5 tuned for high end power instead of low end torque.
This engine was build from ground up to withstand turbo power. Would be interesting to see a CX-5 with swapped engine!
