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.

Feds investigating 2010-11 Mazda CX-9 CUVs over braking issues

The National Highway Traffic Safety Administration is investigating 62,000, 2010-2011 Mazda CX-9 models over brake problems. The government safety watchdog says it has received seven complaints of an observed loss of power braking power to stop the crossover, according to the The Detroit News.
The NHTSA complaints say that the problem causes a hard pedal, increased braking effort and reduced braking effectiveness. Some complaints allege that they hear a hissing noise during braking similar to the sound of air leaving the tires. No injuries or crashes have been reported.
"As always, we are fully cooperating with NHTSA on their investigation. We cannot comment further at this time," said Mazda spokesperson Tamara Mlynarczyk to The Detroit News.
