Racing Hype: Mazda Has First Public Test Of Their New Diesel TUDOR Protype Race Car

There are just 17 more days until the first race of the brand new TUDOR Series (in case you’re behind the TUDOR Series is pretty much the merger of the Rolex series and American LeMans) at the ROLEX 24 hour race in Daytona.  Recently the teams held their first public test at the “Roar Before 24” event and Mazda grabbed the spotlight with the official reveal of their new SKYACTIV diesel powered prototype race car.  Mazda is actually bringing two factory-backed cars to the series with SpeedSource.  As such the same drive line up that SpeedSource fans are familiar with will be piloting the new diesel prototype cars.  Sylvain Tremblay and Tom Long will drive the #70 car while Joel Miller and Tristan Nunez will drive the #07.

Mazda’s new car will definitely receive a baptism in fire as it has to go up against a full field of other prototype and GT cars alike in the Rolex 24 hours of Daytona race.  It will be tough going but a good way to see if the setup they’ve put together really works.  Speaking of set ups, Mazdaspeed has been kind enough to include a full spec sheet of the new prototype car in the press release below.  Fun fact: 51% of the SKYACTIV diesel engine in the prototype race car is the same as production SKYACTIV diesel engines in the current road car line up!  You can also see an HD resolution shot of the new race car by clicking the thumbnail below.

Press Release:

Mazda Ready to Roar at TUDOR United SportsCar Championship Test

Mazda Announces Driver Line-up and Talks Specs 

 (DAYTONA BEACH, Fla.) — Mazda has long believed in promoting from within, including filling those rare ‘factory team’ driver slots.  Mazda Motorsports will field a pair of factory-backed SKYACTIV Technology-powered prototypes in the 2014 TUDOR United SportsCar Championship.  Behind the wheel will be the four drivers who delivered nine race wins and the 2013 Grand-Am GX Manufacturers Championship for Mazda.  Sylvain Tremblay and Tom Long will share the #70 car while Joel Miller and Tristan Nunez will co-pilot the #07.  The team took their first public laps at the annual pre-season “Roar Before the 24” test at Daytona International Speedway yesterday.  The test concludes tomorrow with the season opening Rolex 24 Hour race on January 25-26.

“There is no shortage of great racing talent in America”, noted John Doonan, Director of Motorsports for Mazda North American Operations.  “The decision for this year was relatively simple though as our 2013 line-up excelled both on and off the track.  Sylvain, Tom, Joel, and Tristan are all talented behind the wheel, but just as importantly, they act as a true team, supporting everyone at Mazda and SpeedSource.  Our objective is to demonstrate Mazda SKYACTIV Technology to both hardcore racing fans and the mainstream public.  With so many changes in 2014, including the new series itself, there will be a steep learning curve for everyone and we needed the best students in the sport.  We’ll announce our third drivers for the Rolex 24 at a later date, but rest assured they all fit the same mold of being team thinkers and both will have Mazda heritage in their blood.” 

As part of its challenger frame of mind, Mazda is the only car company racing in the TUDOR Championship with a diesel engine.  The SKYACTIV-D Clean Diesel race engine is a true production-based engine and a carry-over from the development work done with the Mazda6 GX-class racing cars.  The engine is 51 percent stock by parts count, and 63 percent stock by weight.  Mazda chose this path as it is the most honest way to demonstrate the performance, quality, durability and reliability of Mazda powerplants.
