Clean Diesel Technology – Mazda’s SKYACTIV-D Race Engine

As more manufacturers invest in diesel motorsports, more and more technologies are being developed. Here is a relatively new entry into the racing industry from Mazda.

The Mazda SKYACTIV-D clean diesel engine in the video above was taken at SpeedSource Race Engineering of Florida. They have been working with engineers to develop what can only be called an “amazing performance engine”. Not only is this a light weight (aluminum block) engine, but it easily achieves their horsepower and durability goals.

GX classJohn Doonan, Motorsports Director Mazda North American Operations, noted: “The SpeedSource engineering team, working with the Mazda engineers, have been flat out for months on this engine development. We’re happy to report that the engine is meeting the performance targets for both power and endurance. That means 400+ hp for over 50 hours, with an engine that includes a very long list of production Mazda parts. This is not a pure race engine; it is a production block SKYACTIV-D. We’re excited about having our newest engine powering our newest car.”

Yes, you read that right! The aluminum block is actually a factory block that is going in their production vehicles. These new engines are light weight, low compression, high performance engines that aren’t bogged down with all of the same emissions equipment that our trucks have.

Mazda could be onto something here and we really hope to see more manufacturers continue to follow in their footsteps with new technology, especially technology that doesn’t require DPF’s and Urea Injection.

Below is a video that covers some of the new technology in their SKYACTIV-D production vehicle.
