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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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.

eBay Find of the Day: 1990 Mazda Miata with just 27 original miles

Some cars have low mileage, and others have close to no miles at all. This 1990 Mazda Miata, currently listed on eBay Motors and located in Kingman, Arizona, falls into the latter category with only 27 miles on the odometer, according to the seller. But we have to wonder: how did one of the best-driving, most influential sports cars of the past two decades sit without being driven for 24 years? Consider it the seller's loss on this one.
The seller says he bought the car with 20 miles on it, and explains 6.9 miles were added when the car was towed home on a car dolly. It was never registered. Furthermore, the seller says the car didn't come with a set of keys, so he had to have a set made. Though the paint is clean and shiny, the Miata didn't escape minor cosmetic damage over the years, with scratches on the hood, the trunk and the factory hardtop that is included with the car. The front, right fender has a small dent as well, which can be seen in a picture. The seller says the car was stored in a building with windows, so the paint is faded a bit in some places. It's missing its antenna and the battery, and the only non-original parts on the car are the windshield wipers. The clear-title car comes with all paperwork, according to the seller, but, besides the owners manual, he didn't specify what other documentation would be included.
With bidding currently at $10,300 and the reserve not met, this Miata definitely isn't the deal of the century, and we have to question where the value is in this one. The way we see it, it's hard to justify the money if it can't be driven as-is (come on, no battery?), has questionable history, isn't rare and sat in storage for its whole existence. The "weather cracked" tires are probably just the first rubber parts on the car that need to be replaced before it can be driven, but at least the spark plugs were removed and the cylinders were filled with Marvel Mystery Oil prior to storage, which helps to prevent rust and corrosion from forming in the engine.

Mazda delays US launch of Skyactiv-D engine

Japanese automakers haven't lead the charge towards diesel power in the same way as, say, the Germans have. But Mazda is out to change that. It has been following Audi's lead on the racetrack with oil-burning racecars right here in America, and will soon translate that excitement to the road by introducing its Skyactiv-D engine in North America. It just won't happen as soon as we expected.
Mazda announced today that, while its diesel engine meets current emissions requirements, the company has decided once again to push back an introduction originally slated to kick off in the Spring. According to the brief statement below, Mazda wants to take more time to find "the right balance between fuel economy and Mazda-appropriate driving performance."
In other words, the Zoom-Zoom brand apparently thinks its diesel engine doesn't deliver the zoom-zoom American drivers would expect, so we'll have to wait just a little bit longer. Details to follow closer to launch, whenever that will ultimately take place.
