Mazda hits Vegas with a pair of Sixes

Despite the fact that the annual SEMA show is more of an exercise in what "could be" than what "will be," it gives automakers the chance to stretch the legs of some of its most important models. Take the 2014 Mazda6, for example - it's hardly new, having gone on sale early this year - but this year's SEMA expo marks the first time Mazda has been able to show off the customization possibilities for its sleek midsize sedan. To that end, the Japanese automaker has arrived in Las Vegas with two very different takes on its sexy Six.
First up is the Mazda6 Club Sport you see above, wearing a "motorsports-inspired" gray, black and red accent-color scheme that, as Mazda says, is "represented in not-so-subtle angular lines reminiscent of a car speeding past your line of sight." The whole car is done up in a base color of Composite Grey, and uses a Brilliant Black roof to match the similarly colored front, side and rear diffusers, as well as the rear spoiler. Mazda has fitted the Club Sport with Rays 57 Motorsport G07FXX 20-inch wheels, wrapped in Yokohama 245/35R20 tires. Powering the CS is Mazda's 2.2-liter Skyactiv-D diesel four-cylinder engine (that we'll get in the standard Six early next year), and other changes include an H&R spring kit, larger Brembo brakes and a Racing Beat exhaust.
And then there's the Ceramic 6 Concept, pictured right. The name comes from the car's Ceramic White paint, though we don't really get the Taupe Silver accent stripes. Mazda says they're meant to mimic "the linear frequency patterns found on the likes of couture dresses and flowing fabrics," but it just looks a bit overwrought to us. The Mazda6 already has so many clean lines, why add more?

Mazda has no plans for an RX-9, despite ongoing rotary development

We know Mazda is capable of making wonderful cars in any form or bodystyle. It also likes to tease enthusiasts with promising concepts like the stunning RX-Vision. In news that's sure to raise the ire of enthusiasts around the world, it seems the automaker has no plans to follow through with a production version of that beautiful, Soul Red coupe. In fact, it doesn't look like Mazda is interested in building any sports car that would slot above the Miata. In an interview with Automotive News, Mazda CEO Masamichi Kogai responded with a simple "No" when asked if Mazda has plans for a larger sports car entry. Kogai was asked if Mazda has any plans for a production rotary. He said that the 1.5- and 2.0-liter engines in the Miata are more exhilarating. That's a debatable and subjective argument that thousands of rotary owners both past and present would likely disagree with. It's more likely that despite ongoing development of the Wankel, Mazda is still struggling to meet emissions standards. Despite the advantages of a rotary (high power-to-weight ratio, compact size, rev-happy nature), it's not very fuel efficient and struggles with emissions testing. Also, despite the prestige and attention a halo sports coupe could potentially bring, Mazda is a small, independent automaker that needs to focus on mass appeal. Creating an all-new design with a unique engine isn't cheap. Badging a non-rotary car as an RX would be sacrilege, so don't expect an RX anything anytime in the near future. Current RX owners should take a moment to lament. Their car probably needs another quart of oil anyway. Related Video:

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.
