Mazda has announced its official press-release about new Skyactive-D. The engine will be available in 2013. The race engines will use a stock 2.2-liter block with a two-stage turbo, just like the production version. Redline sits at a relatively lofty 5,200 rpm and the engine uses a very low 14:1 compression ratio. If you're keeping track, that's the lowest diesel compression ratio in the world.
Skyactiv-D is a full 10 percent lighter than the outgoing 2.2-liter MZR-CD diesel and that it generates up to 20 percent better fuel economy, as well. That's partially thanks to a 20 percent reduction in internal friction.
Seems Mazda tries to make revolutionary engines its feature – firstly were rotary engines and now it’s Skyactive-D.
