2009-2013 Mazda6 door latch recall covers 161k cars

Mazda is voluntarily recalling 161,400 Mazda6 cars due to door latch mounting screws that may loosen, which could cause a door to open while the vehicle is in motion, thereby increasing the risk of accident or injury. The recall covers 2009 through 2013 Mazda6 models manufactured between February 4, 2008 and August 24, 2012.
The recall is expected to begin by October 18, 2013. Mazda will notify owners, and dealers will provide repairs free of charge. Scroll down for the official recall notice from the National Highway Traffic Safety Administration.

Recharge Wrap-up: Tesla road rage video, Mazda tests EVs vs. hybrids

A Tesla Model S driver was caught driving recklessly in a dashcam video. On Toronto's Don Valley Parkway, the driver of a white Model S can bee seen speeding along the left shoulder. Another car moves partway onto the shoulder to block the driver, who moves back into the left lane. As traffic slows, the driver pulls back onto the shoulder and speeds away. The folks at Teslarati suggest that this serves as an example of why vehicle autonomy could make the roadways safer. See the video above, and read more at Teslarati. Formula E will be broadcast live on Italy's Rai network for the next two seasons. The programming will include the live races, as well as practice and qualifying highlights, podium celebrations, interviews and other pre- and post-race coverage. "It's a great opportunity for Formula E and motorsport fans to have Rai broadcasting the live races of our series in Italy," says Trulli Formula E team owner Jarno Trulli. "It's a step forward to make the series grow and get stronger after a successful first season. I'm looking forward to cooperate with Rai and show the Italian fans what we are truly doing with our technology." Read more from Formula E. A new study links a decline in cancer risk to California's air quality regulations. The study from CARB found that cancer risk from toxic air contaminants declined 76 percent from 1990 to 2012, a time period that corresponds with regulations targeting those contaminants. Even as the amount of diesel miles driven has steadily increased, cancer risk from diesel particulate matter has declined significantly. The paper predicts that cancer risk will continue to drop as a result of controls on toxic emissions. Read more at Green Car Congress. Mazda is conducting consumer trials of hybrid and electric vehicles in Japan to gauge reception. Depending on whether hybrids or EVs prove to be more popular, Mazda will adopt one of the two types of powertrain for future production vehicles. The automaker is currently testing an electric Mazda2 against a hybrid Mazda3. While this round of testing is focused on the automaker's home market, Mazda may need to expand trials to the US in response to tightening regulations in California. Read more at Green Car Reports.

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.
