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.

Import pickup truck-killing Chicken Tax to be repealed?

After over 50 years, the so-called Chicken Tax may finally be going the way of the dodo. Two pending trade deals with countries in the Pacific Rim and Europe potentially could open the US auto market up to imported trucks, if the measures pass. Although, it still might be a while before you can own that Volkswagen Amarok or Toyota Hilux, if ever. The 25-percent import tariff that the Chicken Tax imposes on foreign trucks essentially makes the things all but impossible to sell one profitably in the US, which lends a distinct advantage to domestic pickups. Both the Trans-Pacific Partnership with 12 counties and Transatlantic Trade and Investment Partnership with the European Union would finally end the charge. According to Automotive News though, don't expect new pickups to flood the market, at least not immediately. These deals might roll back the tariff gradually over time, and in the case of Japan, it could be as long as 25 years before fully free trade. Furthermore, Thailand, a major truck builder in Asia, isn't currently part of the deal, and any new models here would still need to meet safety and emissions rules, as well. Automotive News gauged the very early intentions of several automakers with foreign-built trucks, and they weren't necessarily champing at the bit to start imports. Toyota thinks the Hilux sits between the Tundra and Tacoma, and Mazda doesn't think the BT-50 fits its image here. Also, VW doesn't necessarily want to bring the Amarok over from Hannover. There is previous precedent for companies at least considering bringing in pickup trucks after the Chicken Tax's demise, though. The Pacific free trade deal could be done as soon as this fall, while the EU one is likely further out, according to Automotive News. Given enough time, the more accessible ports could allow some new trucks to enter the market.

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.
