2018 Mazda MX-5 Miata and MX-5 Miata RF pricing announced

At Chicago, Mazda has announced official 2018 pricing for the MX-5 Miata, both soft-top and RF. The trick-roofed RF version, or Retractable Fastback, has a coupe-like power hardtop that opens up into a targa. It's only natural that there are MX-5 models on display at the Chicago Auto Show, as 29 years earlier the original Miata was unveiled there. All ND generation cars sold in the U.S. have the 155-horsepower Skyactiv-G engine with a choice of six-speed manual or six-speed automatic. While the canvas-topped 2018 MX-5 starts from $25,295 as a manual Sport, the RF bypasses the Sport spec and starts directly from the Club, which for the RF means a $31,910 starting price, or $355 more than for 2017; the soft-top 2018 Club costs $29,555 in comparison, or a measly $120 hike. The manual Club has a limited slip differential, a front strut brace and Bilstein suspension. Similarly to the soft-top car, the RF also gets a Brembo/BBS brake/wheel/appearance package that hikes the price to $35,680 — and that is only available with manual transmission. That package costs $32,925 for the soft-top, which has also a $700 Recaro sport seating option for the aforementioned Brembo/BBS package, but that is unavailable for the RF. Grand Touring comes with automatic climate control, heated leather seats and adaptive lighting, at a price of $30,195 for the soft top and $32,750 for the RF. Add new-for-2018 Nappa leather for the Grand Touring for $300. At launch in the 2017 model year, the RF Grand Touring was priced $3,000 dearer than a comparable soft-top version, but that difference has now shrunk by $500.

2019 Mazda MX-5 Miata 30th Anniversary Edition goes bold

For a car with a mischievous grin and penchant for fun, the MX-5 Miata's color palette is on the drab side, but thankfully the 30th Anniversary Edition gets a vivid hue called Racing Orange. Mazda says it "evokes the breaking dawn of an exciting new day," and that it's partly inspired by the bright yellow of the Miata Club Racer concept from 1989. That's all well and good, but it looks to us more like the orange from the 1991 Le Mans-winning Mazda 787B race car. Whatever the reason, we dig the color. It will be important that the new owners like it, too, because the color is everywhere. It's on the brake calipers, door sills, air vents, stitching and piping. Everything else is a black or charcoal color, including the gorgeous Rays forged aluminum wheels, exclusive to this model, and the Alcantara trim on the dash, doors and seats. All versions of the special Miata come with Recaro seats, Brembo brakes, Bose sound system and Apple CarPlay and Android Auto. The manual models add a limited-slip differential, Bilstein shocks and a front shock tower brace. Mazda isn't making many of these special Miatas, with just 3,000 of the soft top and RF combined for the world. The U.S. will get only 500. Customers can order one now at a special configuration website, and they had better bring plenty of cash. The manual soft top starts at $35,915, and the manual RF starts at $38,515. Adding an automatic ups the price by $499 on the soft top and $400 on the RF. Related Video:

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.
