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.

Mazda2 successor to ride atop shortened CX-5 platform

Mazda, looking to make the most of its new, lightweight Skyactiv vehicle architecture, will allegedly use a version of the CX-5 crossover's platform to underpin its next-generation Mazda2 hatchback, according to a report from Just-Auto.com. Of course, the Mazda2 is a much smaller vehicle than its larger CUV stablemate, so some serious chopping will no doubt be in order when it comes time to engineer the replacement for the company's smallest hatch.
Currently, the CX-5 and the sleek new Mazda6 share many of the same platform components, and this architecture will already be scaled down to support the next-generation Mazda3 sedan and hatchback, which will debut later this year. Just-Auto.com states that all of Mazda's remaining front-wheel-drive vehicles will eventually switch to reworked versions of this Skyactiv platform, including the replacement for the larger CX-9 crossover.
Also of note, Mazda will reportedly be switching to shorter, four-year lifecycles for its vehicles. This means that the newly launched Mazda6 will be replaced for the 2016 calendar year, with a refresh coming sometime in 2014. That said, vehicles with platforms supplied by other automakers (like the upcoming MX-5 Miata replacement that will share its underpinnings with an Alfa Romeo product) will not necessarily follow this four-year rule.

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.
