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.

Nissan Recalls More Than One Million Vehicles For Air Bags

Nissan is recalling just over one million cars, SUVs and vans because the front passenger air bags may not inflate in a crash. It's the company's second recall to fix the same problem. The recall affects the Altima midsize car, Leaf electric car, Pathfinder SUV and Sentra compact models from the 2013 and 2014 model years, as well as the NV200 Taxi van and Infiniti JX35 SUV from 2013. Also covered are the Infiniti QX60 and Q50 SUVs from 2014. In documents filed with the National Highway Traffic Safety Administration, Nissan says the vehicles' computer software may not detect an adult in the passenger seat. If that happens, the air bags won't inflate. Nissan will notify owners and dealers will update the software for free. The recall is expected to start in mid-April. Most of the vehicles were recalled in February of last year for a similar problem. Dealers replaced seat sensors, but Nissan said it continued to get consumer complaints and warranty claims in vehicles that had been repaired. Front passenger seats have sensors that determine the passenger's weight and turn off air bags off if a child is on board. The malfunctioning sensors can turn the air bags off even if an adult is in the seat. Nissan received three reports of air bags failing to inflate in a crash. Spokesman Steve Yeager said in an e-mail that he is not sure if anyone was hurt in those incidents. There have been no deaths due to the problem, he said. The recall affects almost 990,000 vehicles in the U.S., another 60,000 in Canada and small numbers in other countries, Yeager said. Related Gallery Nissan Searches For Identity In America
