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.

Teen Miata enthusiast and friend of Autoblog passes away

When Thomas' illness made it impossible for him to drive, he relied on friends to do it for him.
Attending the reveal of the 2016 MX-5 Miata and the subsequent 25th anniversary celebration at Mazda Raceway Laguna Seca confirmed that the little roadster maintains broad appeal, one not limited to the elderly or a certain gender as detractors might have you believe. In fact, the assembled crowd was surprisingly youthful, particularly amongst the club racer set and tuners. But one young Miata owner and superfan unfortunately wasn't in attendance - Thomas Jost, 19, was busy fighting for his life in a Maryland hospital.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.
