Mazda rumored to bring rotary-powered RX-9 concept to Tokyo

Stop us if you've heard this one before: Mazda will bring a rotary-powered sports car to the next big auto show. Okay, so we stopped for a second, but the show must go on. Following an official teaser image (shown above) late last month, Motoring.com.au has what it claims are renderings of the curvy, two-door coupe – called the RX-9 – that Mazda will bring to the Tokyo Motor Show later this month. The images show a far softer styling than Mazda's current crop of Kodo-inspired vehicles, while the overall look screams of a modern-day Cosmo Sport, the Japanese brand's first rotary-powered vehicle. And though that connection alone might be enough to justify whisperings of a successor to the RX-7 and RX-8, Motoring claims there will be an even more overt sign of this concept's power source. "Look to the Cosmo Sport," an inside source told the Aussie website, signaling that the Mazda stand would feature the vintage two-door. "The Cosmo has no earthly reason for being there unless..." The rotary rumor, if it comes true, won't exactly be what we're use to. While Motoring brings up the previously reported 16X – a 1.6-liter two-rotor – it builds on our 2013 report. According to the Aussies, the new engine could feature a two-stage electric turbocharger, be paired with a hybrid powertrain, offer up to 450 horsepower, and we're guessing, be hilariously complicated. Joking aside, it sounds like Mazda's goals here are admirable. A rotary-equipped sports car that could counter the 1.3-liter RX-8 engine's appetite for fuel and improve on its mediocre low and mid-range torque would be interesting indeed. As for those renderings, Motoring has front and rear three-quarter images. Comparing the rear with our original teaser leaves the look open to interpretation, but after seriously upping the exposure on the teaser (thanks Photoshop), the taillights and overall profile shape look to be a spot-on match. In front, the long hood shares some Kodo elements, like the headlights and grille, but its undeniable coupe shape – a long hood and very short deck – are far more organic and, dare we say, calm, than Mazda's other vehicles. You can take a closer look at the renderings over at Motoring's website. Do that, and then head back and let us know what you think of these RX-9 rumors. Is Mazda finally going to be bringing a rotary back to market?

2019 Mazda CX-3 small crossover will start at $21,365

The figures are in for the 2019 Mazda CX-3 subcompact crossover, which will start at $21,365 when it arrives in showrooms later this month. That's $280 above the outgoing model, including a $975 destination and handling fee. Fuel economy figures are also now in from the EPA. When equipped with front-wheel drive, the 2019 CX-3 gets 29 miles per gallon in the city and 34 on the highway for a combined 31 mpg. The all-wheel-drive version is rated at 27 mpg in the city, 32 on the highway and 29 combined. Which are ... exactly the same figures as the outgoing version (so much for the promised fuel economy improvements). We detailed most of what's new about the 2019 version back in March at the New York Auto Show. Mostly, they're non-cosmetic changes: The carryover 2.0-liter Skyactiv four-cylinder picks up a couple more horsepower and pound-feet of torque for 148 total horsepower and 146 pound-feet of torque, joining a six-speed automatic transmission with manual-shift and sport modes. It also gets Mazda's G-Vectoring Control driving technology, a sportier, retuned suspension and improvements to make the driving experience quieter and more refined. Mazda says it's also added an electronic parking brake, which necessitated a redesign of the center console and armrest, adding storage space, and it redesigned the front seats and added a new rear armrest with built-in cupholders. Standard features include a new direct tire-pressure monitoring system and blind-spot monitoring with rear cross-traffic alert, two USB ports, a rearview camera, hands-free Bluetooth calling and audio pairing capability, and the 7-inch Mazda Connect full-color infotainment and diagnostic display, controllable via voice command or control knob. The new Sport i-ACTIVSENSE Package of safety technologies is available for an extra $1,100. It adds features including smart city braking support with pedestrian detection, lane departure warning, radar cruise control with stop-and-go function, LED headlights and LED combination tail lights. Other trim levels include Touring, which adds 18-inch wheels and keyless entry, and the top-level Grand Touring, which starts at $26,720 and $28,120 for front- and all-wheel-drive configurations, respectively. Grand Touring includes the Sport i-ACTIVSENSE Package, plus Parchment or black full-leather seating with high-gloss pleated piping and chrome accents on the front bumper and side sills, among other features.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
