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.

Mazda Furai concept designer talks about his car's passing

Last week, there was mourning at the Autoblog offices as word trickled in that the Mazda Furai concept - one of the coolest, best-looking showcars to grace an auto show stage since the wild and crazy 1960s -had been killed. It was killed on the track with the folks from Top Gear in attendance. We're sure the gods of driving would have wanted it to die on a circuit, but that doesn't make its fiery passing any easier to deal with.
The Furai is the rare concept car that had a lasting appeal with enthusiasts, partly because it was a real, functioning racecar, complete with a wacky three-rotor Wankel engine and cutting-edge Nagare design. Now that it's gone, though, Road & Track's Mallory McMorrow, who was an intern at Mazda Design when the Furai was being styled in 2007, has published an interview with one of the men who penned the Mazda showcar's striking exterior, Carlos Salaff. It's a great piece on the emotional connection between a designer and his creation, and one you should take the time to read. Click on over to R&T for the full story.

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.
