Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mazda expands scope of vehicles affected by Takata airbag recall to 330k

Earlier this week a Reuters report indicated that Mazda was considering a nationwide expansion of its recall for vehicles equipped with Takata airbag inflators. The company has now confirmed said expansion, with the vehicle count jumping from 86,770 to 330,000 affected in the US. As before, the affected vehicles are Mazda6 and RX-8 cars from the 2004 to 2008 model years. Mazda reports that Takata has tested a "large number of inflators removed from Mazda vehicles" and not found any to be "non-compliant" as of yet. With that said, the company also reports in its statement that one 2005 Mazda6, located in Florida, has been identified as having had an "abnormal" deployment of the driver's side airbag. For what it's worth, though the company's statement references the Takata inflator issue as a proper recall, it is calling its own program of notification a "Safety Improvement Campaign" for the moment. Find the full, if brief, Mazda press release in the form below. UPDATED MAZDA STATEMENT REGARDING TAKATA AIRBAGS Dec 11, 2014 WASHINGTON, DC (December 11, 2014) – In addition to the actions announced on December 4, 2014, as discussed in a separate document, Mazda today announced the following steps in the Takata recall: Mazda will institute a nationwide Safety Improvement Campaign of 2004-2008 model-year Mazda6 and RX-8 models equipped with certain Takata airbag inflators. The nationwide Safety Improvement Campaign will cover the driver's-side airbag inflator, as Mazda has not made a safety defect determination at this time. This action will support us to gather additional parts for examination and to promote customer satisfaction and safety. There are approximately 330,000 vehicles included in this Safety Improvement Campaign in the United States So far, Takata has tested a large number of inflators removed from Mazda vehicles, and NONE have been found to be non-compliant at this time One vehicle – a 2005 Mazda6 located in Florida – has been identified as having experienced an abnormal driver's-side airbag deployment. Mazda has worked closely with NHTSA on this situation Mazda will participate in the independent, industry-wide joint testing program for Takata airbag inflators For history, on December 4, 2014, Mazda announced: It would expand the area of the high-temperature, high-humidity region recall to include the Gulf Coast states.

2013 North American Car and Truck/Utility of the Year finalists announced [w/poll]

2012 is almost in the books and automakers are spending December gearing up for the 2013 auto show season, which tips off next month at the Detroit Auto Show. Traditionally, the latter opens up with the announcement of the North American Car and Truck/Utility of the Year awards, and this year figures to be no different.
But up until this moment, we didn't know which six vehicles would be parked ahead of the stage as finalists, with executives and engineers waiting for the winners to be disclosed. Whittled down from October's "short list" of nominees (11 cars and 10 truck/utility vehicles), the finalists are as follows:
