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

Mazda's mission for the 2017 CX-5: Smooth out the NVH

NVH: the dreaded noise, vibration, and harshness. According to current Mazda CX-5 owners, as well as those who decided against becoming owners, NVH was its biggest area of need. Traveling in the CX-5 was just too loud, so Mazda's engineers made sure that the redesigned, second-generation model would offer its occupants a more serene environment in keeping with quieter competitors. To reduce wind noise, more aerodynamic parts were strategically placed about the exterior, while extra efforts were made to reduce low-frequency noises on coarse surfaces. According to Mazda engineer Dave Coleman, the new CX-5 is nearly as quiet as its platform-mate, the 2016 CX-9. Actually, to be very accurate, all Mazdas apart from the CX-3 and 2 (aka Toyota iA) now share that platform. Another reason compact SUV buyers opted to skip the CX-5 was its comparatively firm ride. So, while the CX-5 remains "head and shoulders above the segment for handling," according to Coleman, the ride was improved. One of the primary ways of achieving that was the adoption of rigid steering mounts, which allowed for the suspension to be less stiff without a loss in handling precision.

Under the hood, every CX-5 now comes standard with the 2.5-liter Skyactiv-G four-cylinder, with output figures to be announced at a later date. The 2.0-liter, previously standard on the Sport trim, has been exiled to other markets. However, finally making its appearance on these shores is Mazda's 2.2-liter Skyactiv-D diesel engine. Although Mazda did its darndest to make it certifiable in the United States without a urea injection system, it was ultimately unable to do so without resorting to an ultra-sluggish throttle response that engineers deemed was anathema to what was expected of a Mazda. Therefore, the diesel-powered CX-5 will indeed have a DEF tank that will need to be periodically topped off to not run afoul of emissions regulations. Otherwise, the 2017 CX-5 is very much an evolution of the SUV it replaces. Customers thought its size was just right, so its passenger and cargo area remain in the same ballpark.

Miata is always the answer, but not always the best one

The Mazda MX-5 Miata is a surprisingly versatile car. Not only is it hilariously fun on back roads and closed courses, it can also be a decent daily driver thanks to its solid gas mileage and usable trunk. But, it doesn't excel in every driving situation. Specifically long trips at high speeds, and those involving canine companions. This weekend, I did a roughly 500-mile round trip to my parents' home in Indiana to pick up my recently adopted dog. The trip was 90-percent highways, and I heard every single mile. Our MX-5 Miata Club has the minimally insulated top also found on the base level trim, and at highway speeds the wind and road noise fills the cabin with a loud, steady roar. This likely won't be a problem for fans of white noise, and it can be overcome by the stereo. However, over a few hundred miles, it starts to get old. The suspension, while superb for carving corners, also gets tiresome. On rough Rust Belt highways, it would become a bit overwhelmed, and the whole car would shiver and shake. On the plus side, nothing squeaked, rattled, or fell off in these instances. There are a few other quirks that show up on long trips. The small pedal box and floor-mounted throttle means that there isn't a particularly comfortable place to rest your right foot when the cruise control is set. Neither the door nor the center console have much padding either, so leaning your knees against them for long periods of time isn't advisable. The good news is that the seat itself was surprisingly comfortable, and never once was I feeling any back pain. Plus, when not using the cruise control, the seating position is great, allowing me to stretch out and relax. When I picked up my four-legged compatriot (a 7-year-old mix of unknown breeds named Ruby, pictured above), things became a tad tight. Standing up, she thoroughly filled the passenger compartment. For reference, she's a little over 50 pounds and stands a little more than 2 feet tall. Much bigger dogs, like my family's coonhound and German shepherd mix, won't really fit. This also made her prone to nearly face-planting on the dashboard anytime the car slowed down. She eventually figured out that simply curling up on the seat bottom was the best choice, and then slept for most of the trip. So it worked out, but I think I may have found the limit of a Miata's dog capacity. Would any of this make me want a Miata less? Certainly not. That is if I had a second car.
