Infiniti Q Inspiration Concept shows a future with variable compression

For weeks, Infiniti has been teasing the Q Inspiration Concept ahead of its official debut at the Detroit Auto Show. Details were absent, but the design was clean, swoopy athletic. Not seeing any tailpipes on the rear end, we hoped it could sport some kind of electrified powertrain, but surmised that Infiniti could take the opportunity to further showcase its variable compression turbocharged engine technology. Now, Inifniti has officially taken the wraps off its Q Inspiration Concept, and has indeed chosen to use the stunning show car to demonstrate "near future applications" of the potent yet efficient VC-Turbo tech. VC-Turbo made its production debut in the 2019 QX50 at the 2017 Los Angeles Auto Show. Here, in the Q Inspiration, VC-Turbo allows Infiniti designers to make the most of the packaging, taking advantage of the compact powertrain to increase the size of the cabin while maintaining the footprint of a mid-size car. Electric automakers like Fisker, Lucid Motors and the like have been doing something similar with electric powertrains, but Infiniti's VC-Turbo allows the company to do something similar with technology that is ready for primetime, while still bridging the gap to more efficient future powertrains. VC-Turbo, as we've learned earlier, allows the engine to change and optimize compression ratios on the fly, between 8:1 for high-performance situations, to 14:1 for maximum efficiency. Mounted to the exhaust manifold integrated in the cylinder heads of the four-cylinder engine is a single-scroll turbocharger. The system, says Infiniti, provides the torque and response of a hybrid or turbodiesel powertrain without sacrificing efficiency. In the Q Inspiration, the power is directed to four wheels via a front-biased all-wheel-drive drivetrain. The system can direct torque to the rear wheels individually as needed. As a design study, the Q Inspiration is a success. The proportions and lines are sleek and attractive, accentuated by the car's white paint. There's kind of a lot going on up front, with a large "double-arch" grille at the leading edge. Everything behind that, though, looks particularly harmonious. Its elongated cabin and coupe-like dimensions help provide efficiency while maximizing headroom for the four occupants. It's a car that stands up to close inspection, as attention to detail makes it more interesting the closer you scrutinize it, inside and out.

Infiniti QX70 is fini, for now

We knew it first as the FX, debuting in 2003 as a bulgingly macho SUV/crossover thing with an impossibly long hood. It was quick and powerful, and lower-slung than typical SUVs, more like a tall wagon. Infiniti later dialed the cartoonishness of it back a few notches and started calling it the QX70. Now, the QX70 is going to take a little break, disappearing from the lineup for a few years while QX50 and QX80 redesigns are rolled out. The QX70 is sporty, with a 325-horsepower 3.7-liter V6. But it's an aging model and a bit of a slow seller - last year, Infiniti moved one-seventh as many QX70s as it did its kid-hauling cousin the QX60 - which seats more people (seven, to the QX70's five) and is less expensive. The QX70 was once popular like that, selling 30,964 as the FX in 2004. But that was long, long ago. Last year it sold 6,261. The QX70 nameplate is expected to be back in 2021 or 2022, in a redesign based on the Nissan Murano and built at Nissan's plant in Canton, Miss.

Nissan recalling GT-R, Infiniti crossovers over steering column issue

Nissan has discovered a problem with the steering column on some of its higher-end all-wheel-drive vehicles from a few years back, and has issued a recall in conjunction with the National Highway Traffic Safety Administration to address the issue. The issue revolves around the outer tube on the steering column, which may not be perfectly round. That would put extra stress on the upper steering bearing, which could cause it to fracture, disabling the car's steering ability and potentially leading to a crash. The problem affects Nissan's flagship GT-R supercar – specifically 2009 models manufactured between March 14, 2007, and April 25, 2008) as well as an array of Infiniti crossovers: namely the 2008 EX35 and the 2008-09 FX35 and FX45. In the case of the luxury crossovers, Infiniti dealers are being instructed to replace just the steering shaft, but Nissan dealers will have to replace the entire steering column assembly on the GT-R. All told, the recall is estimated to encompass 16,973 vehicles across the United States. RECALL Subject : Steering Column Tube may be Out of Round Report Receipt Date: FEB 02, 2015 NHTSA Campaign Number: 15V054000 Component(s): STEERING Potential Number of Units Affected: 16,973 Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008 Infiniti EX35 vehicles manufactured June 29, 2007, to April 25, 2008, 2009 Infiniti FX35 and FX45 vehicles manufactured October 31, 2007, to April 16, 2008, and 2009 Nissan GT-R vehicles manufactured March 14, 2007, to April 25, 2008. The steering column outer tube may not be round, resulting in extra stress being applied to the upper steering bearing. This stress may cause the bearing retainer to fracture, creating extra play in the steering wheel or a possible loss of steering. CONSEQUENCE: Extra play in the steering wheel or a loss of steering may increase the risk of a crash. REMEDY: Nissan will notify owners, and dealers will replace the steering shaft on the Infiniti EX35, FX35, and FX45 vehicles, and will replace the steering column assembly on the Nissan GT-R vehicles, free of charge. The manufacturer has not yet provided a notification schedule. Infiniti owners may contact customer service at 1-800-662-6200. Nissan owners may contact the GT-R hotline at 1-866-668-1487.
