Infiniti QX60 AWD vs. Mazda CX-9 Signature

In certain ZIP codes around Dallas, Chevy's Suburban remains the Official SUV of Texas, but Infiniti's QX60 could be the Official Crossover. The Pathfinder-based three-row is everywhere. And while its popularity is based on transporting kids and their stuff, the QX60 is a more urban Suburban. Mazda's CX-9 is not as ubiquitous as the QX60 in McMansion driveways, but it has been making inroads into the near-luxury segment with its near-luxury spec. The CX-9's second generation has obviously upscale intent, in the sheetmetal and throughout the top-line Signature interior. And the prices of these two cars are surprisingly close. INFINITI QX60 AWD: The sheetmetal differentiating Infiniti's QX60 from its volume-oriented Nissan donor is attractive. The changes are subtle, and in profile the Pathfinder and Infiniti are almost identical, but the eye is drawn to the differences in the grille and D-pillar. The Infiniti has a luxury vibe with a more athletic stance. The QX60's interior surfaces seem upscale, but if you want wood it will cost you. In "building our own" and opting for graphite leather with maple trim, the wood requires another $12,000(!) of mandatory packages, including Infiniti's Premium and Premium Plus packages ($1,800 and $2,900, respectively) and $7,300 of Deluxe Tech. So, wood? We wouldn't. But if you do, know the QX60 won't match the larger QX80 in presence or passion, but it is certainly something beyond a rebadged Pathfinder. For you and your passengers, there is 156 cubic feet of interior room; with the second and third rows folded, you can accommodate 76 cubic feet of cargo. Like in most crossovers, that third row is best used by young kids, but taking six adults to lunch won't require too much gymnastics – or chiropractics. On the road, the QX60 is known more for comfort than composure; this isn't an old Buick, but neither is it a BMW. Nissan's 3.5 liter V6 produces generous power (295 horsepower and 270 pound-feet of torque), but it's transmitted to either the front wheels or all wheels via a CVT (continuously variable transmission). Nissan has tried to mitigate the quirkiness, but it's a CVT all the same. At a well-equipped base of $44,000, we like the QX60. But start adding options, and you can approach $60,000, which is real money even in the better ZIP codes. MAZDA CX-9 SIGNATURE: This, ladies and gentlemen, is dramatic. Mazda has absolutely nailed it. Using Mazda's KODO design language on a large platform could have gone wrong.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Weekly Recap: Toyota, Mazda team up to 'make cars better'

Toyota and Mazda are teaming for a noble purpose: to "make cars better." That's how the two Japanese automakers termed their partnership, which was announced this week. So what does this actually mean? The companies said they will set up a joint committee to look for areas of cooperation and named safety and the environment as issues they plan to tackle. From a product perspective, it's believed that Toyota is interested in Mazda's Skyactive engine portfolio. In turn, Mazda has its eye on Toyota's fuel-cell and plug-in hybrid technology. While more specifics were not confirmed, the companies said the "agreement will go beyond the traditional framework of cooperation," and it has the potential to be a long-range partnership. "The main purpose of this initiative is to enhance the appeal of our cars," Toyota president Akio Toyoda said at the announcement. Previously, Mazda has licensed Toyota's hybrid tech and assembled compact cars for Toyota in Mexico. Akio Toyoda said these projects "triggered" the automakers to explore further collaboration. Dave Sullivan, product analysis manager for AutoPacific, said the tie-up echoes Daimler's wide-ranging work with the Renault-Nissan alliance. "This could be a well-groomed match due to each having very unique skill sets," he said. OTHER NEWS & NOTES Volvo selects South Carolina for US factory Volvo confirmed this week that it will build its first US factory in South Carolina, with construction set to begin this fall. The company first revealed plans in March, though it didn't announce a site. The plant will have initial annual production of 100,000 units, though the vehicle or vehicles to be assembled were not specified. The factory, located near Charleston, will open in 2018 and ultimately employ 4,000 people. The facility will help Volvo continue its growth strategy, which includes strengthening its presence in the US market, where it wants to sell more than 100,000 cars per year. "Building a plant in the US is a reflection of Volvo Cars' commitment to the US and the key role the US plays in our growth objectives," Lex Kerssemakers, senior vice president, Americas, said in a statement. Ford GT spied on the road The 2017 Ford GT was spotted testing around the Blue Oval's headquarters in Dearborn, MI, this week. The raw body panels were exposed, and they lacked paint or camouflage. It's the first time the GT has been captured on the street after a spring of auto show reveals.
