This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

We've seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace "Mad Mike" Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower "MADBUL" RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called "RADBUL," and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood. Four-rotor engines are actually popular - builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete - but they're usually being prepped for an RX-7. Mad Mike's choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.

2019 Mazda3 pricing starts at over $20,000, 2.5-liter engine standard

Pricing for the 2019 Mazda3 hatchback and sedan has been announced, and the base price has gone up by about $3,000. The new cheapest model is a front-drive, automatic Mazda3 sedan, and it starts at $21,895. The base Mazda3 now has the 186-horsepower 2.5-liter 4-cylinder as the standard engine, whereas the old model came with a 155-horsepower 2.0-liter engine and manual transmission as standard. Compared like-to-like, a 2018 Mazda3 in a similar spec would be slightly more expensive ($22,035) than the 2019 model. Opting for the hatchback on the base trim adds an additional level of equipment, with 18-inch wheels instead of 16-inch ones, Apple CarPlay and Android Auto, dual automatic climate control, leather wrapped steering wheel and shift knob. It also gets more safety equipment including blind-spot monitoring, automatic emergency braking, radar cruise control, automatic high-beams, automatic wipers and lane-departure warning with lane-keep assist. That all adds up to a $2,600 price increase over a base sedan. These features are available on the sedan for an extra $1,600 in the form of the Select package. For all other trims, opting for the hatchback adds $1,000. Higher trim levels add features such as better sound systems, real leather, a sunroof, heads-up display and power heated seats. In addition to pricing, Mazda revealed drivetrain options for the Mazda3, and they're not great for fans of manual transmissions. The Mazda3 hatchback with front-wheel drive and Premium trim is the only manual offering, and it starts at $28,395. On the upside, at least Mazda isn't relegating manual transmissions to the stripped out versions, but on the downside, there isn't a cheap manual option for those on a budget. And of course, if you want the sedan or all-wheel drive, the six-speed automatic is your only choice. Mazda has told us that it could match a manual with all-wheel drive, but clearly it doesn't see a market for that in the U.S. But like with the addition of the turbocharged Mazda6 and CX-5, if there's demand, such a combination could become available, but keep in mind the odds will still be slim. You can see the full breakdown of trims and prices below. The 2019 Mazda3 will be available in March.

Takata airbag recall spreads to China with 42k Mazda sedans

The scope of the problem with the faulty airbag inflators from Takata continues to broaden and is now reaching China, as well. Mazda is recalling 42,732 Mazda6 units there, produced by its local joint venture partner China FAW Car Company, to replace the front passenger airbags. It comes as part of Mazda's recall of nearly 160,000 vehicles worldwide, including about 34,600 in the US, according to Reuters.
This is the same problem that caused seven automakers in the US to recall an estimated 2.1 million vehicles in late June. The airbag inflators can potentially explode instead of deploying the airbag, which hampers the bag's inflation. In some cases occupants are also hit by the metal shrapnel, which can cause further injuries. In the US, Mazda is repairing the 2003-2007 Mazda6 (pictured above), 2006-2007 Mazdaspeed6, 2004 MPV and 2004-2008 RX-8 originally sold in or currently registered in Florida, Puerto Rico, and Hawaii.
This is hardly the first instance of this issue. Since 2001, there have been 20 recalls tied to the exploding airbags supplied by Takata. The problem is possibly linked to the propellant in the inflators, but there's no conclusive evidence of that yet. Most of the automakers in the US limited the most recent recalls only to a few humid states because moisture potentially exacerbated the problem.
