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.

Living Life Large: Driving $2 million worth of cars in one week

Monterey Car Week has quickly become one of my favorite events of the year. There's something for everyone – classic car shows, modern concepts and new vehicle debuts, auctions, racing, and so much more. From a media perspective, there's also a chance to drive a ton of cars. Many automakers bring their latest wares out to Monterey for us to test during our limited free time, and it's a great opportunity to experience fantastic metal against a gorgeous backdrop. That's exactly what I did this year. Instead of flying into Monterey and being driven around, my journey started in Los Angeles and ended in Napa, and I managed to get behind the wheel of some $2 million worth of new cars. Some were old favorites, and many were new experiences. But looking back, this was one of the best weeks of driving I've had in years. Rather than try to come up with some common arc to tie these cars together, here are my notes on all the cars I tested in California earlier this month, presented in the order in which they were driven. 2016 Mazda CX-3 The CX-3 pictured here isn't the exact one I drove in California, but it's close. The only difference was color – my delivered-to-LAX tester wore Mazda's awesome new Ceramic hue (pictured below on the MX-5 Miata). I used the CX-3 to slum through crummy Los Angeles traffic for two hours on the way out to Santa Barbara, with a quick stop at In-N-Out Burger on the way for good measure. A lot nicer inside than I remember. Everyone praises Mazda for its excellence in engineering and design, but there's a lot to be said for the improvements in overall interior refinement. Quiet, comfortable, and well-equipped; the CX-3 made sitting on the 405 freeway a lot more pleasant. Not all that functional. I had a hard time fitting a week's worth of luggage for two people inside. The cargo area and rear passenger compartment were filled, with only enough room on top to see out the back window. A Honda HR-V would've swallowed all that luggage with plenty of room for more. So good to drive. Not surprising, since this wasn't my first time in the CX-3. I knew this CUV would be good on twisty roads, but on the highway it's really exceptional. Road and wind noise are minimal and the overall ride quality is a comfortable sort of sporty. This is definitely something I could drive every day – it's enjoyable during commuting and entertaining on more interesting roads.

Mazda and Fiat finalize deal for Alfa roadster, next-gen MX-5 Miata

Although a little bit later than expected, Mazda and Fiat have signed a final agreement that will bring a next-generation MX-5 Miata to the Japanese automaker and a new roadster to Alfa Romeo. When the proposed arrangement was announced back in May, the two automakers had hoped to seal the deal last year, but it doesn't appear that the production timeline for these cars has slipped any, with both expected to start rolling off assembly lines in 2015.
Other than a shared chassis with a rear-wheel-drive layout, it sounds like the two cars are still planned to be distinct in their own ways from their styling right down to their engines. Mazda will produce both cars at a plant in Hiroshima, Japan, but it isn't clear what role each automaker will play in the cars' developmental process. The big question, of course, is what clever portmanteau name we can come up with, like Toyobaru. Mazda Romeo is the easy choice, but Alfazda might roll off the tongue a little better.
