Road & Track to take Miata on million-mile march

Road & Track has taken on a Miata project. One hell of a project, if we're honest. You see, the Miata in question, a 1989 example in Mariner Blue, isn't a high-mileage Mazda that the publication intends to fix up, or make race-worthy, or try to flip or give away to a reader or something. No, it's a rather typical well-used NA, with a hefty 325,000 miles on the clock to-date that the staff plans on driving until the six-digit odo reads all zeros again. One million miles or bust (or both, most likely).
Procured for the bargain-basement price of $1,600, complete with seat covers that "really do look like muppet pelts" (according to Zach Bowman) and a bondo-filled love tap on the nose, the NA Miata actually looks like just the sort of fun-machine that a real driving enthusiast would pick up to get some cheap thrills in. The R&T team already has some interesting plans for the Miata, including a potential run up Pikes Peak and loaning it out to readers (or perhaps your author...). Click through to read all about it.

Sweating the small stuff | 2017 Mazda CX-5 First Drive

The 2017 Mazda CX-5's door handles got their own design study. They got their own graphs, maths, and a team of people scientifically analyzing how humans interact with them. There was a whole to-do. And yet, you look at them back-to-back with their predecessors, a Spockian eyebrow reaching to the stars, and wonder what all the fuss was about. But apparently they're better. They're also perfectly illustrative of the entire effort to re-engineer and improve Mazda's best-selling model. At first, the 2017 Mazda CX-5 seems like a sensible evolution of its well-loved predecessor – there's sexier styling, a more premium cabin, and additional features, but the dimensions and engine specs look awfully similar. It certainly looks like one of those "the old car's great, let's not overthink the new one" redesigns. Except it isn't. Dig deeper and you'll see just how much meticulous work – from the door handles to the throttle response – went into making the new CX-5 a crossover that thoroughly trounces the majority of its competition. Take the efforts to make it quieter. According to Mazda's internal measurements, the sound-quelling improvements made for the CX-5's 2016 refresh already made it one of the quietest compact SUVs on the market. That apparently wasn't good enough. To what seems like an absurd degree, Mazda's engineers obsessively examined every nook, cranny, corner, and crevice to sniff out noise and eliminate it. Gaps were filled, insulation was injected, seals were added, air was redirected, glass was double glazed, and carpet replaced plastic coverings. It would seem that the Society of Persnickety Engineers is well represented at Mazda HQ. "I'm not sure how they found some of these," said Mazda vehicle development engineer Dave Coleman with a shake of his head, almost amused by the obsession and dedication of his colleagues across the proverbial hall in the sound-deadening department. (He goes over many of their enhancements in the video below.) And it worked. The new CX-5 is indeed incredibly quiet, even on San Diego's notoriously loud corrugated concrete freeways. It is quiet for a Mazda – a brand previously known for the exact opposite – and the entire segment. Even the fairly quiet 2017 Honda CR-V we drove on the same freeways on the way to San Diego couldn't match it. Actually, much of the driving experience can't be matched by a competitor.

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.
