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 Though that car was withdrawn with turbocharger failure 71 laps in, its diesel powerplant left an indelible impression on the racing community, and that's something Mazda hopes to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

The 2017 Mazda CX-5 is new, and oh so very red

After examining the teaser photo and poring over spy photos, we knew that the 2017 Mazda CX-5 would adopt some design features from the larger CX-9 and Chinese-only CX-4. What we didn't know, though, is that the CX-5 would look like a miniature version of the CX-9. From the outside it's obvious the design is all new. The front of the SUV looks nearly identical to that of the CX-9's. Gone is the cutesy, roundish face in favor of a more angular theme. The headlights are slimmer, while the grille ditches the horizontal bars for a mesh pattern. Mazda calls the design theme Kodo - soul of motion, and the original 2013 CX-5 was the first production model under this mantra. View 12 Photos The changes at the back are less drastic than on the CX-5's new beak. The black trim that underlines the rear fascia is less prominent and the taillights looks leaner, but it's harder to tell the differences between the old and new model. Mazda says the CX-5 will be available with two engines here: the Skyactiv 2.5-liter gasoline engine and the Skyactiv-D 2.2-liter diesel (the Skyactive-D 2.0-liter, currently only used on Sport models, has been dropped for our market). We don't have specifics on power and torque yet, but in the old CX-5 (and current Mazda 3) the 2.5-liter four-cylinder generates 184 horsepower, while the diesel makes 173 hp and 310 pound-feet of torque. We expect front- and all-wheel-drive options, and of course we're hoping that the six-speed manual (previously on the base, front-drive model only) stays around as an alternative to the six-speed automatic. The interior follows the template of recent Mazdas, with the infotainment screen sitting on top of the dashboard with a control knob located aft of the shift lever. We'll have more information on the 2017 CX-5 at the vehicle's debut later today at the 2016 Los Angeles Auto Show. Related Video:

Recharge Wrap-up: 61 miles on Autopilot; Mazda CX-9's 32% mpg improvement

A technology analyst at The Motley Fool used Tesla's Autopilot uninterrupted for 61 miles. In order to see how far the Tesla Model S could drive itself without driver intervention, Daniel Sparks set off on the highway from Monument, Colorado, through Colorado Springs and onward toward Pueblo. Only when a truck encroached on his lane did the driver take command of the wheel, rather than waiting to see what the car would do. "With [the] Model S nearly out of Pueblo and onto a long, boring stretch of highway by the time I had to grab the wheel, chances are I could have made it all the way to Colorado City if it wasn't for this interruption," says Sparks. Read the full account at The Motley Fool. The 2016 Mazda CX-9 offers 32 percent better fuel economy than the outgoing model. The front-wheel-drive CX-9, equipped with Mazda's Skyactiv-G 2.5T engine, gets an EPA-estimated 22 mpg city/28 mpg highway/25 mpg combined. The 2016 CX-9 has shed significant weight compared to its predecessor. Its turbocharged engine uses a Dynamic Pressure Turbo system, which improves performance at lower rpm by controlling the degree of exhaust pulsation according to engine speed. The new CX-9 goes on sale this spring. Read more at Green Car Congress. A group of eight US cities have formed the Energy Secure Cities Coalition (ESCC), pledging to switch their fleets over to alternative fuels. Atlanta, Charlotte, Indianapolis, Orlando, Rochester, Sacramento, San Diego and West Palm Beach will retire their petroleum-powered vehicles in favor of EVs and cars using cleaner fuels like natural gas. The cities expect the change to help improve air quality and save taxpayer money on fuel and maintenance costs. The ESCC hopes to grow to include 25 major cities, removing some 50,000 petroleum-fueled vehicles from service and saving 500,000 barrels of oil per year. Read more in the press release below.
