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 Mazda CX-5 turbo model seemingly confirmed, doesn't come cheap

We reported last month on some leaked documents that announced the 2019 Mazda CX-5 would get the turbocharged 2.5-liter four-cylinder as an option, and it's looking even more official now that additional documents have appeared on Reddit. The new information comes from a "Product Information Bulletin" that not only confirms the engine's availability but reveals pricing, trims and feature sets for the new model year. As it turns out, the turbo CX-5 won't be cheap. The base price for a CX-5 with that engine will be $35,865 with destination. That's about $5,500 more than the cheapest turbocharged Mazda6. There are a couple of reasons for this. The turbo engine will only be available on two new high-end trims for the CX-5, Grand Touring Reserve and Signature. Both of those trims bring a variety of high-end features and options with them. It can also only be paired with all-wheel drive. The Mazda6 turbo engine is available on the slightly lower Grand Touring trim and is only paired to a front-drive drivetrain. Conspicuously absent from the 2019 documentation though is the elusive Skyactiv-D diesel engine. This is strange, since the engine has been rated by the EPA, so it's presumably ready for introduction to the U.S. market. We'll be curious to learn that engine's fate. We could see the turbo gas engine threatening the diesel's U.S. introduction, since it delivers the same amount of torque as the diesel with more horsepower. Plus the diesel didn't get amazing EPA numbers. But that's just speculation on our part, and it's entirely possible the diesel will still come here. The rest of the CX-5 lineup sees some welcome upgrades, too. The infotainment on CX-5s starting with the second-lowest Touring model will get standard Apple CarPlay and Android Auto compatibility. All models also will receive G-Vectoring Plus. The feature, along with the turbo engine option, was announced for the Japanese CX-5 recently. What this system adds is a little bit of braking force to the outside wheel as the driver winds the wheel back to a straight position when exiting a corner or completing a lane-change. The idea is that it helps make the car more stable when straightening out after a turn. Also, although the turbo CX-5 models will be rather pricey, the other CX-5 models won't change much in price. The base Sport trim starts at $200 more than the 2018, the Touring model increases just $100, and the Grand Touring goes up by $400.

Mazda zooms into SEMA 2016 with lighter MX-5 Speedster and RF Kuro concepts

It's almost time for the 2016 SEMA aftermarket show again, if you haven't guessed already by the steady parade of early looks at various show cars. Mazda's MX-5 creations are generally a highlight for us, unapologetic Miata junkies that we are. This year's cars should be just as exciting as last year's, one being a revision of last year's Speedster concept and the other based on the brand new, sexy RF retractable targa top model. Both SEMA MX-5s were designed and built in-house at Mazda's Irvine design studio. This year's Speedster is somehow even lighter than before. Mazda carved 100 pounds out of it, making it a staggering 350 pounds less than a production soft top model. It's also been repainted in a color called "White Ether", which we're imagining looks something like the "Blue Ether" paintjob on last year's highly reflective Speedster minus the blue tint. Mazda will probably never sell a roofless Miata or anything this lightweight, but maybe it should. It looks like it'd be a blast to drive at a road course. And then there's the RF Kuro concept, the first RF-based SEMA show car, which is shown in the teaser above. It doesn't seem terribly extreme, to be honest. It's wearing a matte charcoal paint, which explains the "Kuro" moniker – kuro means "charcoal" in Japanese. A set of 17-inch RAYS forged wheels and MX-5 Cup suspension, and that's about it. Not to knock it; the RF is a sexy looking thing as it sits, and Cup suspension should make it handle even more like a go-kart. Of course, both concepts will be fully revealed at the show next month in Las Vegas. Stay tuned for a dose of concept Miata hotness.Related Video:
