Infiniti serves up ‘Carigami’ models to ease coronavirus quarantine boredom

To the list of things car enthusiasts can do to combat coronavirus quarantine boredom, or keep their restless kids diverted, Inifiniti is serving up what it’s calling “Carigami.” ItÂ’s exactly what it sounds like: origami for cars, more or less. Three models are offered — the Q50 sedan, QX80 SUV and the now-discontinued FX crossover — all in 1:27 scale. All you need is a printer and paper, a craft knife and some glue. ItÂ’s not the first time Nissan has turned to the Japanese art form, having commissioned a full-scale origami version of the Juke on its fifth anniversary in 2015. Outside the Nissan realm, we also recently saw a downloadable origami version of the Tesla Cybertruck. You can download all three Infiniti templates and instructions at Infiniti.com. We especially dig the use of a record turntable as a way to replicate the life-size design turntable automakers display new models on at auto shows.

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.

The yin and yang of the 2017 Infiniti Q50 Red Sport 400

When we first drove the Q50 Red Sport 400, Infiniti had the car out at a prepared slalom-and-cone course in a large, open parking lot. The car was stacked up against another Q50 without the Direct Adaptive Steer steer-by-wire system, and the course was designed to show that the DAS-equipped Red Sport 400 (it's a $1,000 option) required less steering input to master the same course. With all due respect to Infiniti, which is invested in this unfortunate system and has been working hard to revise it, the comparison doesn't make a lot of sense. The non-DAS Red Sport 400 has a steering ratio of 15:1 in RWD and 16.7:1 in AWD forms. The DAS system can vary between 12:1 and 32.9:1 in RWD and 11.8:1 to 32.3:1 in AWD flavors. At its extremes, the DAS system's ratio is vastly different than the fixed-ratio cars. So sure, with a super-quick steering ratio available, the DAS driver's going to do less work. It's all in the gearing. Does this mean it's better, that the steering feel is more natural, that it's easier to hustle quickly? The amount the driver saws at the wheel isn't an indication of that, necessarily. After a few days in a rear-drive Red Sport 400, I'm saying that the spooky disconnection between the driver and the front wheels would be a severe deficit to a driver on a real autocross course. It's not like the DAS system is choosing bad ratios within its range, it's just not supplying the feedback to make it enjoyable. Knowing what your front tires are up to is critical. I can hear you saying right now, "But what Q50 Red Sport 400 owners are going to autocross their cars?" Sure, but it was just a means to an end: showing off the DAS in a good light. And in that case, it probably did. The thing is, in isolation, not back-to-back with a non-DAS car with a slow steering ratio, the DAS system has the same issues it's always had: It simply doesn't feel natural. It doesn't feel intuitive. There doesn't seem to be any real advantage over a slightly quicker rack. I don't hear about people making buying decisions based on how much work they have to do sawing at the wheel, do you? So, that's one side of the Q50 coin – one that's hard to ignore if you're an enthusiast and steering feel is an important connection between you and the vehicle you just dropped a large hunk of change on, and will be spending a lot of your time in. The other is that there's a really compelling reason to drive a Red Sport 400: The 3.0-liter, twin-turbocharged V6 is a monster.
