Petrolicious lets a 1971 Mazda RX-2 howl

Rotary engines scream to the heavens in the best way possible. To hear a wonderful example of the Wankel's battle cry, turn up your speakers and watch Petrolicious highlight an immaculately clean 1971 Mazda RX-2 in Australia. Owner Jason Humble took three years to build his RX-2 from a bare shell, and he started competing with it in vintage racing in 2005. The little coupe's class pits it on track against Mustangs and Camaros, but Humble claims that he's regularly near the top of the pack thanks to the Mazda's communicative chassis. We don't get to see the RX-2 mixing things up on track in the Petrolicious video, but Humble does treat us to a drive through the Australian countryside. He's happy to let the coupe's rotary rev, and the little engine is capable of making a wonderful noise. It's great to see Petrolicious continue to give the spotlight to these sometimes overlooked classic Japanese sports cars.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Next Mazda CX-9 to launch by 2016, could get turbo-four

Mazda has a lot going on these days, what with launching the new Mazda6 and Mazda3, with the new Mazda2 just around the corner. We know the new Miata is also on the way, and after that it looks like the next vehicle in its lineup due for an overhaul is the CX-9 crossover, due to launch by 2016. The move makes sense because the CUV is growing long in the tooth. It was first introduced in 2007 and was refreshed twice since then.
The next-generation CX-9 will move away from Ford-derived components like the V6 in the current model and will likely use a turbocharged four-cylinder engine. However, a final decision hasn't been made yet. "If I ask Mr. Hitomi, our top guy of powertrains at Mazda, he believes the downsizing turbo solution costs more. But real downsizing means six-cylinder to four-cylinder turbo could make sense from a cost point of view," said Mazda's global marketing boss Masahiro Moro to CarAdvice at the New York Auto Show. The executive said a hybrid powertrain option would be unlikely, but markets outside the US could get a diesel, as well.
Moro also tipped his hand at future Mazda model plans. He hints that the Japanese automaker is considering building a luxury vehicle with a six-cylinder engine. "It's too early, we don't have a car yet. But we are collecting advice as to V6 or straight-six," he said to CarAdvice. We'll definitely be watching.
