About 20k Nissan Pathfinder, Infiniti JX models recalled for potentially faulty brakes

The National Highway Traffic Safety Administration has issued a recall for the 2013 Nissan Pathfinder and 2013 Infiniti JX due to a problem with the front brakes. The problem is a result of the brake torque member (a part that attaches the brake caliper to the front suspension), which was cast improperly with a structural weakness that could possibly lead to "reduced braking, increasing the risk of a crash," according to NHTSA. How, you ask? If the part breaks, the brake caliper could move position and possibly make contact with the wheel.
Around 20,000 of these sister crossovers are being recalled, but it doesn't sound like all were equipped with the faulty component. Dealers will inspect vehicles built between December 3, 2012 and January 29, 2013, and replace components from the defective batch. The recall goes into effect next month, but until then, the official recall notice is posted below with information for how owners can contact Nissan.

How Infiniti's 'gas-generated EV' isn't the jumbo shrimp of powertrains

LOS ANGELES — Infiniti recently introduced the concept of what it's calling "gas-generated EV" powertrain technology. At first read, and perhaps everyone thereafter, the term seems contradictory, not unlike "jumbo shrimp." How can an electric vehicle use gasoline? The answer to that is both a technological one and a marketing one. Technologically speaking, Infiniti's electrified powertrain concept is a series hybrid, most comparable to what Honda employs in its Insight, Accord Hybrid and new CR-V Hybrid. In the most basic of terms, the car's electric motor powers the wheels, the battery pack powers the electric motor, and the gasoline engine recharges the battery pack along with regenerative braking. By contrast, a parallel hybrid system as used by Toyota and others can power the wheels with the electric motor, the engine or, most frequently, both simultaneously. The result of a series hybrid is a powertrain that performs and feels more like an electric vehicle, while the engine generally whirs away, often not in step with what your right foot is doing. The Infiniti system is comparable to this, albeit with more powerful motors resulting in a more performance-oriented bent. Here's where things diverge, however. Under certain constant cruise conditions, say on the highway, the Honda system directly connects the engine with the drive wheels for greater efficiency. The Infiniti "gas-generated EV" concept will not, which frees engineers and designers to package the gasoline engine someplace other than under a front hood. In that way, it benefits from the sort of packaging advantages associated with electric vehicles. The closest comparable in this way is the BMW i3, which locates its tiny gasoline engine under the cargo area and does not attach it mechanically to the drive wheels. That's a range extender for an electric vehicle, though, which Infiniti is quick to insist is not what's going on here. There is no plug. This is a hybrid. So what's the deal with that name? If it walks like a duck and talks like a duck Â… Talking with Infiniti Group VP Jeff Pope, "gas-generated EV" is definitely a work in progress or at least a placeholder for something catchier and perhaps less contradictory in the future. "Why we're using 'gas-generated EV' is to get away from 'hybrid,' because 'hybrid' is associated with a parallel hybrid system, which has a gas engine and an electric motor that both run the powertrain.

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.
