2014 Mazda6 i Sport

In an automotive landscape dominated by platform sharing, technology exchange and any number of other cross-fertilization/cost-saving/amortization exercises, it's actually pretty rare that we get to drive a new car that is as "all-new" as this, the 2014 Mazda6. With brand-spanking new Skyactiv architecture throughout - engine, transmission, body and chassis all included - this 6 represents a new era of flexible production and cutting edge running gear for the happily lithe car company.
Our own Jonathon Ramsey did a cracking job of running the Mazda6 through its First Drive paces a few months ago, and sufficiently impressed upon us just how good looking a car this is for the midsize sedan segment. Suffice it to say, now, then, that this is easily the most interesting (and quite possibly the most beautiful) midsize sedan in the segment today. However, as Mr. Ramsey reviewed a fully contented example of the 6 - one equipped with the six-speed automatic transmission - we took advantage of Mazda's North American launch event of the car to suss out the base Mazda6 i Sport, complete with its six-speed Skyactiv manual gearbox. This may not shock you, but the stripper's pretty good, too.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

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.
