Mazda brings slick sports-car concept to Tokyo

Mazda teased a slick spots-car concept Wednesday that will debut at the 2015 Tokyo Motor Show. The as-yet unnamed concept promises to blend elements from the company's heritage with a sleek and modern shape. It apparently takes the form of a front-engine, two-door coupe – always a favorite configuration – with a sloping roofline and classic hood-to-greenhouse ratio. It'll be displayed alongside the Koeru concept (which returns home for its Japanese debut), a handful of MX-5 Miatas, and a classic 1967 Cosmo Sport 110S – the marque's original, rotary-powered sports car. We have a good feeling that it's the latter from which the new concept principally draws its inspiration, albeit with different dimensions than the long-tailed original - and hopefully a little RX-7 thrown in for good measure. We'll have to hold on a while longer to find out, but we're looking forward to seeing the finished product. Mazda to Unveil New Sports Car Concept at Tokyo Motor Show -- Japan-debut of Mazda KOERU and racing-spec Mazda Roadsters among fourteen models on display -- HIROSHIMA, Japan, Sept. 29, 2015 /PRNewswire/ -- Mazda Motor Corporation will hold the world premiere of a new sports car concept model at the 2015 Tokyo Motor Show, which runs from October 30 through November 8.*1 A total of 14 models will be on display at the Mazda stand, including crossover concept Mazda KOERU making its first appearance in Japan, two racing-spec Mazda Roadsters (known as Mazda MX-5 outside Japan) and the Cosmo Sport (110S outside Japan), first introduced in 1967. The design of the sports car concept to be unveiled in Tokyo is modern but maintains a sense of lineage and authenticity, appearing almost to condense Mazda's entire history of sports car development into a single model. In line with the company's theme for the Tokyo Motor Show this year, "Accelerate toward our dreams," Mazda will make an appeal for the brand's unique approach to driving pleasure. In addition to the sports car concept, Mazda KOERU will be on display along with new-generation models featuring SKYACTIV Technologies and KODO—Soul of Motion design. A motor sports exhibit will feature racing-spec Roadsters and the Cosmo Sport will complement a heritage display showing Mazda's history of convention-defying engineering.

Why the 38-mpg 2014 Mazda6 is on dealer lots, but you can't drive it

If you stop by your local Mazda dealer this month, with any luck, you'll see the much-anticipated 2014 Mazda6 parked in the showroom - there are already a few hundred of them out there. That's quite an accomplishment in light of the fact that it isn't even calendar year 2013. The move is part of a strategic decision by the Japanese automaker, which is hoping to capitalize on holiday showroom traffic. (The last five days of the year are typically among the busiest dealer days all year).
If you happen to spy the rakish sedan, you may notice something missing - a window sticker. That's because Mazda (like other automakers) can't legally display the Monroney on a 2014 model year vehicle until January 1, 2013. According to Autoblog sources, Mazda dealers are legally prohibited from letting you test drive until the start of 2013, so it's more of a sneak preview than anything else. Even so, we reckon shoppers will be impressed when they finally get a look at those window stickers - Mazda hasn't announced fuel economy figures yet, but Autoblog has learned that the 2014 model will carry a pair of impressive numbers: EPA estimates of 27 miles per gallon in the city and 38 mpg on the highway using regular gas.

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.
