    Patent Application Shows Mazda Still Working On the Rotary Engine


    • Mazda files a patent application for a new rotary engine, everyone goes crazy!

    Last October, Mazda revealed the RX-Vision concept. This concept featured a brand new rotary engine called SkyActiv-R. At the time, Mazda was keeping quiet on specifics of the engine. But it showed that Mazda was working on a next-gen rotary. Now, we have some clues as to the SkyActiv-R.

     

    autoevolution found a patent application filed by Mazda last fall and published last month by the U.S. Patent and Trademark office. The drawings in the application show the engine turned 180 degrees with the exhaust port on top and intake port on the bottom. This repositioning allows for minimal turbo lag thanks to the short distance from the exhaust port to the turbo. It also allows the engine to mounted lower in the vehicle to improve the center of gravity.

     

    Now this is only a patent application. It doesn't mean Mazda will put this exact engine into production. But for fans of the rotary engine, it gives them some hope that the engine will soon return.

    Ya always have to protect your intellectual property but my gut tells me the Rotary is dead and we will not see it back in the US. Better chance of having an RX7 EV than a new Rotary version that meets the emissions regulations.

      Mazda is in the process of trying to position themselves as a premium brand that you can actually afford. Autoblog had the chance to speak with Jacques Flynn, a lead exterior designer, and Jacob Brown, a PR representative for Mazda. 
      A key part of Mazda's premium plans is their Kodo design language. Flynn explained that Mazda will be simplifying and evolving the look of Kodo on their various models. A key example is the recently introduced second-generation CX-5. Compared to the outgoing model, the new CX-5 features fewer curves to make it look tauter. 
      Diesel will also play a key part in Mazda's premium ambitions. Brown explained that diesel has the air of premium surrounding it as luxury automakers, for the most part, offer them in the U.S. Mazda was hoping not to use urea-injection for their diesel models, but ultimately had to give in to meet emission standards and performance benchmarks.
      Those hoping that Mazda would bring back Mazdaspeed on some performance models will be disappointed to hear it could be a while before this happens. Both Flynn and Brown said the company's focus is "on making the core line-up cohesive." Being a small company, they cannot take any chances on working a number of projects at the same time since that could result in a misstep or two.

      Mazda Reports Best January Sales Since 2012
      Mazda CX-5 Posts Record Month IRVINE, Calif., Feb. 1, 2017 /PRNewswire/ -- Mazda North American Operations (MNAO) today reported January U.S. sales of 21,698 vehicles, representing an increase of 10.1 percent versus January of last year, and the best January sales month in five years. Solid sales performance across the lineup was headlined by consumers' continued strong desire for crossover SUVs.
      Key January sales notes:
      The Mazda CX-5 posted its best-ever January with 8,068 vehicles sold, showing continued momentum leading up to the on-sale date of the all-new 2017 model later this Spring. This number represents an increase of 14.2 percent year-over-year (YOY). The Mazda CX-9 posted an increase of 210.7 percent YOY, with 1,591 vehicles sold. Mazda's CX crossover SUV sales—including the CX-3, CX-5 and CX-9—were up 21.1 percent YOY with 10,843 sold. Of the total CX-line sales, 60 percent of vehicles were equipped with i-ACTIV All-Wheel Drive. Sales of the Mazda6 started the year off strong, posting a 28.3 percent increase YOY with 3,300 vehicles sold. Even with much of the U.S. experiencing winter weather, popularity of the MX-5 Miata continues with 929 vehicles sold. This number represents an increase of 65.9 percent YOY. Sales totals for the MX-5 include both the MX-5 soft top and MX-5 RF. Mazda Motor de Mexico (MMdM) reported January sales of 4,759 vehicles, down 18.6 percent versus January of last year.

      Homogeneous charge compression ignition or HCCI engines are a unique prospect - use compression to ignite gasoline, like in a diesel vehicle. This allows for better fuel economy and lower emissions. A number of automakers have built prototypes and said they would be putting them into production down the road, but it has never happened. That may change in the near future.
      The Nikkei Asian Review reports that Mazda will be launching an HCCI engine for the 2018 Mazda3 (Axela in Japan). This will be part of Mazda's second-generation of SkyActiv technologies to improve fuel economy. According to the report, the engine could give certain Mazda3 models a fuel economy figure of 30 kilometers per liter (about 71 mpg on the U.S. cycle). The report doesn't say if this is for city, highway, or combined.
      Can Mazda do it or will it be like the others and not appear? We'll be watching to find out that answer.

      So help me.... One of these days these Miami drivers are going to make me test the loss damage waiver on my rental car. Worst drivers in the US.

      I have one co-worker who has been a thorn in my side for the past 6 months.... but I have to admit that when I need something done that is in his area of expertise, he goes after it like an angry rabid chihuahua and gets it done.
