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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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

Japanese automakers ramping production for renewed American sales

The 2011 earthquake and tsunami that struck Japan took quite the toll on the automotive industry in that nation. Not content to lean on that tragedy as excuse for slagging sales, the Japanese automakers are planning on a major production expansion in North America. The aim is to reclaim the market share lost from the Tsunami-based dip, and overcome a dollar/yen exchange rate that makes exporting to America unprofitable.
Following the Tsunami, Japanese automakers ramped up production in their North American facilities to compensate, but according to Automotive News, Nissan, Honda and others have all reported plans for still-further increased production in the year ahead. As part of this ramp-up, Mazda will open a facility in Salamnca, Mexico before March of 2014. Part of that increase in output is 50,000 units of a Toyota-badged compact car, which Mazda will produce.
Other Mexican production facilities opening include a Honda plant, which will open in Spring 2014 in Celaya, and a Nissan plant, set to open later this year in Aguascalientes. Nissan also said that it will need another plant in North America within the next five years. According to Nissan Boss Carlos Ghosn, the company aims to raise its stake in the US market from 8 percent to 10, and adding production will help achieve that goal. Even Mitsubishi is aiming to boost production at its Normal, Illinois plant. Production of the Outlander Sport is currently at 50,000, which Mitsubishi wants to raise to 70,000.

2016 Mazda MX-5 Miata will rock 2.0L SkyActiv engine in US, 1.5L elsewhere

Let the speculation finally end - we know what will power the next-generation 2016 Mazda MX-5 Miata, and it's not turbocharged. The US model will get a SkyActiv 2.0-liter engine and six-speed manual, while models in the rest of the world have a 1.5-liter engine, confirming earlier rumors.
Unfortunately, Mazda isn't letting loose how much power either of these mills make just yet. For sake of comparison, the current SkyActiv 2.0 in the Mazda3 produces 155 horsepower and 150 pound-feet of torque, and the 1.5-liter in the UK (and elsewhere) has about 99 hp and 110 lb-ft of twist. However, the current Miata produces 167 hp and 140 lb-ft.
But fret not droptop fans. The company's brochure from the 2014 Paris Motor Show confirms, "all available drivetrains have been specially tuned for the all-new MX-5," which at least hints at the possibility of more performance. Also, even if the numbers remain untouched, the new Miata should feel even more sporting on the open road. That's because Mazda says the new model weighs in the neighborhood of 2,200 pounds; with that in mind, the 2016 car would boast around 14.19 pounds per horsepower versus 14.85 lb/hp in the present MX-5. Progress!
