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.

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.

A tuned 1973 Mazda RX-3 is all business on Petrolicious

People with good memories might remember Savant Young and his highly modified 1973 Mazda RX-3 from an appearance on Jay Leno's Garage last summer. Now Petrolicious spotlights him and learns more about his amazing rotary coupe. After extensive upgrades, his car packs an estimated 400 horsepower, which is especially potent with only around 2,000 pounds to move around. Young thinks his Mazda is a perfect expression of his personality as a martial artist because it offers no frills and is all about business. This coupe looks ready for a fight, too, and sounds like a swarm of angry bees going down the road. Young works hard during the week but makes time to drive the RX-3 every weekend. We can understand why. A few hours enjoying this rotary could definitely erase some stress. Get a taste of this amazing machine in Petrolicious' latest video. If you want to experience another cool rotary, the channel profiled an RX-2 racecar from Australia last month. Related Video:
