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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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 going back to oval grille with next MX-5 Miata

The original Mazda MX-5 Miata was distinguished by an oval grille - a design trait that gradually evolved into the smiling cat face on the latest model. But Mazda, according to the latest intel, is planning on returning to that oval grille with the new model in the works.
The revised grille will cap a slightly longer form than models past, while still keeping weight down to a minimum. The stretched wheelbase was reportedly adopted in order to meet the requirements of Alfa Romeo, which is jointly developing the new platform together with Mazda for use on a new roadster of its own.
The new Miata is expected to adopt the 1.5-liter Skyactiv four found in the Mazda3, albeit returned to rev higher and deliver more power and torque, mated to either a six-speed manual or automatic. The Alfa version, meanwhile, is expected to use a 1.4-liter turbo four with a dual-clutch transmission. Sources anticipate the new MX-5 to debut first, possibly at the 2015 Chicago Auto Show a little less than a year from now.

2014 Mazda6 i Sport

In an automotive landscape dominated by platform sharing, technology exchange and any number of other cross-fertilization/cost-saving/amortization exercises, it's actually pretty rare that we get to drive a new car that is as "all-new" as this, the 2014 Mazda6. With brand-spanking new Skyactiv architecture throughout - engine, transmission, body and chassis all included - this 6 represents a new era of flexible production and cutting edge running gear for the happily lithe car company.
Our own Jonathon Ramsey did a cracking job of running the Mazda6 through its First Drive paces a few months ago, and sufficiently impressed upon us just how good looking a car this is for the midsize sedan segment. Suffice it to say, now, then, that this is easily the most interesting (and quite possibly the most beautiful) midsize sedan in the segment today. However, as Mr. Ramsey reviewed a fully contented example of the 6 - one equipped with the six-speed automatic transmission - we took advantage of Mazda's North American launch event of the car to suss out the base Mazda6 i Sport, complete with its six-speed Skyactiv manual gearbox. This may not shock you, but the stripper's pretty good, too.
