2014 Mazda Skyactiv Prototype looks ready for Daytona

With less than two weeks before the Mazda Skyactiv Prototype makes its race debut at the 2014 Rolex 24 at Daytona, the Japanese Zoom-Zoom brand brought its diesel-powered racer to the floor of the 2014 Detroit Auto Show.
The red prototype marks Mazda's return to prototype racing, and will campaign the inaugural Tudor United SportsCar Championship using a 2.2-liter, SkyActiv-D diesel engine. With 451 horsepower on tap and 580 pound-feet of torque, the racer should stand up well against a field of gas-powered competitors.
Should the Skyactiv win Daytona, it'll be a coup for Mazda. The racer is running an engine with over 50 percent of its parts drawn from the oft-delayed production Skyactiv-D. Head up top for our full gallery of images of the new Skyactiv Prototype. The 2014 Rolex 24 will be run from January 25 to 26.

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:

Next-gen Mazda MX-5 could use carbon fiber to cut weight

The current Mazda MX-5 Miata has only been out for a few years, but the automaker is allegedly looking for ways to lighten the next one. According to a report from Autocar, Mazda is looking to carbon fiber to help the next-generation MX-5 cut weight and use a smaller engine. Despite having more safety features, modern amenities, and a stiffer body, the current MX-5 is the same size as the original sports car from 1990 and weighs less than its immediate predecessor. In a recent interview with Autocar, Nobuhiro Yamamoto, head of the Miata program, revealed that the next generation of the Miata will probably stay the same size, but could be even lighter thanks to the utilization of carbon fiber. The current MX-5 uses high-strength steel and aluminum, and Mazda doesn't use carbon fiber in any of its cars. Carbon fiber is expensive to incorporate into road-going vehicles, and so Yamamoto notes that Mazda has been hard at work making it more affordable. A lighter car could result in a smaller engine, Yamamoto said. In the US, the MX-5 comes with a 2.0-liter four-cylinder engine that makes 155 horsepower, while the Japanese and European version comes with a 1.5-liter, 130-hp engine. A smaller engine would make the sports car even lighter. It's unknown at this time if the automaker is collaborating with another automaker or a supplier to make produce carbon fiber, or if it'll make it in-house. There's no word on how much carbon fiber the next MX-5 will wear or how it will affect the sports car's price. Autocar reports that the next MX-5 won't arrive anytime before 2021, which could make the ND MX-5's lifespan an unusually short five years long. With cars getting heavier, it's nice to hear that Mazda is working on finding a way to make its lightweight sports car even lighter.
