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 QX50 confirmed for NY debut

It's been eight years now since Infiniti took the wraps off its smaller crossover. The model initially known as the EX was subsequently renamed the QX50 in the brand's broad nomenclature shakeup a couple of years ago, but now it's received what promises to be a comprehensive makeover to be revealed at the New York Auto Show next week. Though it hasn't given us any photos to go on (that's the current model pictured above), Infiniti has revealed that "the updated QX50 has a wheelbase increase of more than three inches, creating additional rear legroom and interior volume." We're also told to expect "new front and rear fascias, wheels, side sills, as well as a slightly higher ride stance." Nissan's rival to the likes of the BMW X3, Audi Q5, Volvo XC60 et al is offered Stateside with a 3.7-liter V6 driving the rear wheels or all four, but is offered overseas as well with a 3.0-liter turbodiesel. We'd expect the revised model to carry over the same engines, perhaps with some revisions, when it reaches showrooms this fall.

Nissan recalls 640k crossovers for wiring issue, hood release

The National Highway Traffic Safety Administration has announced two separate recalls affecting hundreds of thousands of Nissan crossovers. The larger of the two involves the electrical system in 2008-2013 model year Rogue CUVs. In affected vehicles, a mixture of moisture and salt seeping in through the carpet on the driver's side could cause the harness connector to short, potentially causing a fire. The issue involves Nissan Rogues manufactured between March 7, 2007, and November 26, 2013, as well as examples of the 2014 Rogue Select manufactured between September 23, 2013, and July 2, 2014. All told, that comes to an estimated 468,815 units in the United States alone. The second recall affects the relatively smaller quantity of 170,665 vehicles, made up of 2013-14 Nissan Pathfinder, 2014 Pathfinder Hybrid, 2013 Infiniti JX35, 2014 QX60 and 2014 QX60 Hybrid models. (The JX35 was recently relabeled as the QX60 under Infiniti's new nomenclature.) The issue affecting some of those vehicles revolves around a hood release cable that may not properly latch. Nissan is notifying owners of the affected units to bring their vehicles in to have the wiring checked and to replace the harness connector and seal in the former case, and to have the hood release mechanism modified in the latter. All told, an estimated 639,480 vehicles are being recalled as part of the two campaigns. RECALL Subject : Electrical Short Due to Water Seepage Report Receipt Date: JAN 26, 2015 NHTSA Campaign Number: 15V032000 Component(s): ELECTRICAL SYSTEM Manufacturer: Nissan North America, Inc. SUMMARY: Nissan North America, Inc. (Nissan) is recalling certain model year 2008-2013 Nissan Rogue vehicles manufactured March 7, 2007, to November 26, 2013, and 2014 Nissan Rogue Select vehicles manufactured September 23, 2013, to July 2, 2014. The affected vehicles may experience an electrical short in the harness connector due to a mixture of snow/water and salt seeping through the carpet on the driver side floor near the harness connector. CONSEQUENCE: An electrical short can cause a vehicle fire. REMEDY: Nissan will notify owners, and dealers will inspect the kick panel wiring harness connector and will if necessary install a new harness connector and waterproof seal, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Nissan customer service at 1-800-647-7261.
