Mazda says 83 percent of new cars bear Skyactiv moniker

Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least. While the Japanese automaker's US sales in February fell 2.4 percent from a year earlier, Skyactiv accounted for 83 percent of its sales last month. Most notably, Mazda6 sales jumped 46 percent from a year earlier, while Mazda CX-5 sales were up 72 percent. The company also celebrated the opening of its factory in Salamanca, Mexico, where it will make models such as the Mazda2 and Mazda3. The company is not resting on its fuel-economy laurels either, apparently. In January, it was reported the company is hard at work on its next-generation Skyactiv technology, which will boost fuel efficiency by as much as 30 percent by using diesel-like high compression. As it is, Mazda had the highest fleetwide fuel economy of any major automaker in the US for the 2013 model year with a 27.5 mile per gallon average, according to the Environmental Protection Agency (EPA). Honda came in second with 27 mpg. Check out Mazda's press release below. MAZDA SKYACTIV® TECHNOLOGY SETS RECORDS IN FEBRUARY - Mazda Celebrates Grand Opening of All-New Production Facility in Salamanca, Mexico - IRVINE, Calif., March 3, 2014 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported February U.S. sales of 24,431 vehicles, representing a decrease of 2.4 percent versus last year. Year-to-date sales through February are down 6.7 percent versus last year, with 43,155 vehicles sold. Key February sales notes: Mazda's SKYACTIV® TECHNOLOGY accounted for 83.2 percent of all vehicle sales during the month of February. This is the largest percentage of Mazdas equipped with SKYACTIV TECHNOLOGY sold in one month, and second-best month of total volume ever with 20,245 vehicles sold. Mazda6 experienced its second-best February since 2008 with 3,945 vehicles sold, representing an increase of 46.0 percent, year-over-year (YOY). February 2014 was CX-5's best month ever with 9,353 vehicles sold, good for an increase of 71.6 percent, YOY. February was one of the most historic months for Mazda as it celebrated the grand opening of its all-new engine and vehicle assembly plant in Salamanca, Mexico.

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.

IIHS Top Safety Pick and Top Safety Pick+ awards get tougher: Here are the latest winners

Automakers love to trumpet the accolades from the Insurance Institute for Highway Safety, but the agency keeps making its best grades harder to achieve. For 2020, it is raising the bar again, requiring a better score in the passenger-side small-overlap crash test, wider availability of top-performing headlights, and automatic emergency braking systems that effectively avoid collisions with pedestrians, in addition to its previous benchmarks. Why the 2020 criteria is harder: To be named either a Top Safety Pick or Top Safety Pick+, the required performance in the passenger-side small-overlap crash test has been raised from Acceptable to Good, meaning that the model must achieve Good ratings in all crash tests. The Nissan Rogue, for example, scored an Acceptable in the passenger-side small overlap crash, and so it loses its Top Safety Pick rating for 2020. To achieve either of the top ratings, a vehicle's automatic emergency braking system must effectively avoid hitting pedestrians as well as other vehicles. (The automatic emergency braking system can be optional, but then the award applies to the model only when so equipped.) Any vehicle whose automatic emergency braking system does not include pedestrian detection would lose its TSP or TSP+ rating for 2020, the Ram 1500 being one example. To be named a Top Safety Pick+, the model can have no variant with headlights that achieve less than an Acceptable rating (most new cars have different headlights — often LEDs — that are exclusive to upper trim levels).
