Mazda6 diesel delayed until April

Diesel enthusiasts waiting on the new Skyactiv-D-powered Mazda6 will have to wait a bit longer. The shapely fuel-efficient four-door has just had its North American launch pushed back to April, due to delays in emissions testing. Mazda had originally planned to launch the Mazda6 diesel before the end of this year, making the four- to five-month delay a rather serious one.
Mazda's senior vice president of US operations, Robert Davis, told Mazda employees in a letter obtained by Automotive News that, "final certification testing - the results of which are looking encouraging - is taking longer than we had initially expected." Following this letter, Mazda made an official announcement:
"The on-sale date for Mazda6 SKYACTIV-D clean-diesel has been moved to late-Spring 2014, to accommodate final emissions testing and certification. We are pleased with the ongoing development and are excited to launch this much-anticipated vehicle in North America. 2014 Mazda6 sales continue to exceed both our expectations and our production abilities, and supplies of the car are short at dealers across the U.S. More information on the SKYACTIV-D clean diesel Mazda6 will be available closer to the on-sale date."

White House clears way for NHTSA to mandate vehicle black boxes

At present, over 90 percent of all new vehicles sold in the United States today are equipped with event data recorders, more commonly known as black boxes. If the National Highway Traffic Safety Administration gets its way, that already high figure will swell to a full 100 percent in short order.
Such automotive black boxes have been in existence since the 1990s, and all current Ford, General Motors, Mazda and Toyota vehicles are so equipped. NHTSA has been attempting to make these data recorders mandatory for automakers, and according to The Detroit News, the White House Office of Management Budget has just finished reviewing the proposal, clearing the way. Now NHTSA is expected to draft new legislation to make the boxes a requirement.
One problem with current black boxes is that there's no set of standards for automakers to follow when creating what bits of data are recorded, and for how long or in what format it is stored. In other words, one automaker's box is probably not compatible with its competitors.

This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

We've seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace "Mad Mike" Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower "MADBUL" RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called "RADBUL," and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood. Four-rotor engines are actually popular - builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete - but they're usually being prepped for an RX-7. Mad Mike's choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.
