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.

A beautiful conundrum | 2017 Infiniti Q60 First Drive

"OK, this should be fun." Hands are rubbed together excitedly. It's a rear-wheel-drive sport coupe painted candy apple red. It's sleek, slinky, and uniquely styled. It's from the same folks who, in the 2000s, finally showed that BMW could be matched in the whole sport sedan/coupe game. Oh, and it has 400 horsepower. Four-hundred! With a four. And yet the 2017 Infiniti Q60 underwhelms. What looks so good on paper instead is rather conflicted, stuck somewhere in no-man's land between the traditional expectations of a performance sport coupe and those of comfier, more luxurious cruisers that isolate and pamper their occupants. It's a serious effort with serious engineering and a clear desire to be innovative, but at least in the range-topping Red Sport model we tested, it fails to come together in a way that truly excites or indulges. A great coupe should do one or the other, and ideally both. To explain, let's start under the hood, where Infiniti's all-new "VR" series 3.0-liter twin-turbo V6 makes its second appearance after debuting in the Q60's four-door sibling, the Q50. In the Q60 Silver Sport model, it produces 300 horsepower and 295 pound-feet of torque courtesy a pair of turbochargers that create 8.7 psi of boost. In the Red Sport, the knob is turned up to 14.7 psi, resulting in the oh-so-salivatory magic number of 400 hp along with 350 lb-ft of torque. A device known as an optical turbo speed sensor, special to the Red Sport, manages and maintains that extra boost, while an electric motor fitted to the valve timing system serves to quell any loss in throttle response due to forced induction. The Red also gets a second water-cooled intercooler, which, in both models, is distinctive for its more compact size, shorter airflow path, and, according to Infiniti, a resulting reduction in turbo lag and more immediate engine response. It's certainly a clear improvement on the somewhat rough 3.7-liter "VQ" V6 it replaces, which increasingly felt and sounded a little out of place in a luxury car. The new VR30DDTT, as it's so eloquently named, is buttery smooth and indeed responsive, likely capable of convincing luxury-car owners used to naturally aspirated V6s that everything's business as usual. Honestly, its character is reminiscent of a silky Honda V6. In some respects, that's a great thing. In others, it's where the Q60 starts to fall flat.

Infiniti teases a new concept for the Detroit Auto Show

Infiniti is the latest company to join a steadily growing list of big reveals at the 2018 Detroit Auto Show. It just released a teaser image of a concept it will display. It looks fairly typical of Infiniti, with long flowing curves, and the company's signature grille. And of course, it will be painted white. The company revealed very little about it, not even a name. But a quote from Infiniti's Executive Design Director may shed a bit of light on the car. He talks about "more compact and less intrusive powertrains" giving freedom to design, and that this car has a "long cabin." This leads us to believe that this concept may feature some kind of alternative powertrain, perhaps hybrid or fully electric. It could even use a smaller version of Infiniti's variable compression engine. We also think that this car may have a profile akin to the Jaguar I-Pace, with a much more cab-forward look. When Jaguar revealed the I-Pace, it made a big deal about how going to electric propulsion gave them the opportunity to rethink what looks luxurious, sporty and aggressive, since there wasn't an engine at the front to require a long nose. Infiniti's design director's words sound pretty similar. We'll have more information and photos when the car is fully revealed at the 2018 Detroit Auto Show.
