Watch this 1,500-hp Mazda MX-5 smoke a race track

In December 2014 we watched New Zealand drifter "Mad Mike" Whiddett assemble his RADBUL, an NC-series Mazda MX-5 Miata with a four-rotor engine aided by twin Garrett turbochargers. The Dr. Frankensteins at engine builders Pulse Performance expected their creation to be good for 1,500 horsepower. This year we get to watch Whiddett run the monster around Highlands Motorsports Park in New Zealand, brewing up enough tire smoke to set of fire alarms in the International Space Station. When the car was finished in February Pulse Performance put it on the dyno, toning down the boost because "the tires easily smoked the rollers." The result on the day was 1,032 horsepower from the 2.6-liter engine. When Whiddett campaigned it at the Forth Worth, TX round of this year's Formula Drift Pro Championship, he said tiny adjustments have a huge effect on the way the car behaves so they were still trying to find the right balance a few months into the season because of the testing limit outside of competition. Unsurprisingly, he also said the car "is so damn fast that I'm actually having trouble slowing down." RADBUL is the third in Whiddett's line of Mazda drift specials, after the RX-8 BADBUL and the RX-7 MADBUL.

2019 Mazda3 shows off factory bodykit, Miata gets a hardtop at Tokyo Auto Salon

The 2019 Mazda3 wasn't exactly lacking in the sporty style department when it was shown last month in L.A. But everyone, including Mazda, knows that doesn't mean it can't be even sportier. As such, the company is showing off a version of the new compact hatchback at Tokyo Auto Salon, a modified car and aftermarket parts show, with a body kit. It's a subtle one, consisting of a black front lip spoiler, black side skirts, and a longer, slightly upturned rear spoiler. Its low-key design fits in well with the Mazda3's taut, clean lines, and it makes the car look lower and more purposeful. The Mazda3 isn't the only car getting some love at the Tokyo Auto Salon. The company will display an MX-5 Miata with a removable hardtop made of carbon fiber. Now, you may remember that Mazda does offer a hardtop, but just for racing drivers. That top is a bit odd looking with a really high rear-end to clear motorsports-spec roll bars and cages. This top follows the lines of the roadster's soft top, looking much more sleek. Neither sets of parts here have been announced for production, but we wouldn't be surprised to see them show up as Mazda accessories. The Mazda3 body kit in particular seems a shoe-in, since the previous generation Mazda3 had a very similar appearance package available. The Miata top certainly seems as though it was designed with regular consumers in mind. Its future is less certain, though. For one thing, Mazda can point to the Miata RF if you want a solid roof. Then again, Mazda still offered a removable hardtop for conventional Miata roadsters even after the original power-retractable hardtop model was introduced. If it does come to market, though, expect it to be made from more affordable fiberglass and be painted in factory colors. Related Video: This content is hosted by a third party.

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.
