Mazda Skyactiv-D racer first diesel to run at Indy in 60 years

While it may not be touting the old "Win on Sunday, sell on Monday" axiom we all know and love, Mazda recognizes that racing can only improve its cars. And so it's no surprise that the Japanese automaker is testing and refining its Skyactiv-D diesel engine by sending it out on various race tracks around the country - notably being the first diesel ever to compete at Daytona and the first to notch a Grand Am win at Road Atlanta.
Next up? Indy. It has been over 60 years since a diesel-powered machine ran at the Indianapolis Motor Speedway, and the Cummins-powered racer that competed in the 1952 Indy 500 with a 6.6-liter inline-six-cylinder oil-burner was a fast and brutal machine that set a new lap record in qualifying leading up to the race. Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to accomplish once again.
Mazda says that the diesel engine in its race car is pretty darn close to stock - 51 percent stock by parts count, and 63 percent stock by weight - which means the way it performs in competition is at least a somewhat meaningful way to the stock engine's durability in the real world. Check out the image of the Mazda6 Skyactiv-D racer posing alongside the 1952 Cummins above (click to enlarge) and feel free to peruse the press release below for the rest of the details.

Mazda recalls 109k Tribute models for rust issue

The Mazda Tribute is being hit with a similar recall as its platform-mate the Ford Escape underwent a few weeks ago. Mazda is recalling 109,000 Tributes from model years 2001 to 2004. On the trucks, the subframe can rust from road salt, potentially causing the lower control arm to detach. If this happens, a loss of steering control could occur.
Mazda is adding a reinforcement crossbrace for added strength on the affected models. The recall covers Tributes currently registered in or originally sold in 20 northern states and Washington, DC, where road salt is used.
The reinforcement braces aren't available yet to do the repair. Mazda will send a letter in May to owners of affected vehicles that will inform them of the problem, and a second letter telling them when the parts will be ready. Scroll down to read the full recall press release.

Watch this 1,500-hp Mazda MX-5 smoke a race track

In December 2014 we watched New Zealand drifter "Mad Mike" Whiddett assemble his RADBUL, an NC-series Mazda MX-5 Miata with a four-rotor engine aided by twin Garrett turbochargers. The Dr. Frankensteins at engine builders Pulse Performance expected their creation to be good for 1,500 horsepower. This year we get to watch Whiddett run the monster around Highlands Motorsports Park in New Zealand, brewing up enough tire smoke to set of fire alarms in the International Space Station. When the car was finished in February Pulse Performance put it on the dyno, toning down the boost because "the tires easily smoked the rollers." The result on the day was 1,032 horsepower from the 2.6-liter engine. When Whiddett campaigned it at the Forth Worth, TX round of this year's Formula Drift Pro Championship, he said tiny adjustments have a huge effect on the way the car behaves so they were still trying to find the right balance a few months into the season because of the testing limit outside of competition. Unsurprisingly, he also said the car "is so damn fast that I'm actually having trouble slowing down." RADBUL is the third in Whiddett's line of Mazda drift specials, after the RX-8 BADBUL and the RX-7 MADBUL.
