Race teams in the Grand Am GX class can now get their hands on a new diesel powerplant. Mazda has announced the company will supply the new Skyactiv-D for the 2013 season. 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.
Mazda says the 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.
