Autoblog sell-it-yourself highlight: 2013 Infiniti QX56

As Lincoln announces an all-new Navigator at this year's New York auto show, and General Motors' Arlington (Texas) plant runs 24/7 cranking out Tahoes, Yukons, and Escalades, Infiniti's big QX56/80 continues to gain fans in a great many upmarket zip codes. And its appeal – for those with an appreciation for Big Foot footprints – is obvious. Built atop Nissan's Patrol platform, the QX56 offers high levels of refinement with cubic yards of utility. Introduced by Nissan's Infiniti division in 2011, you would assume any inaugural bugs had been worked out by 2013, the QX's third model year. Power was supplied, in the press vernacular, by Nissan's proven 5.6-liter V8 producing 400 horsepower and 413 pound-feet of torque. A seven-speed automatic transmission was standard on all models, and while the additional speeds might suggest some semblance of efficiency, no one should confuse this big QX with a Toyota Prius. Our 'for sale' example, with 84,000 miles, represents above-average mileage for a 4-year old vehicle. But if those are largely highway miles in and around Madison, Mississippi, and service records are available, you shouldn't be too concerned. This is, with proper maintenance, a 200,000-mile platform, leaving you about 116,000 miles for your $37,000. And the 'ask' seems about $5,000 too dear; perhaps the seller will throw in a gas card.

F1-inspired, 563-horsepower Infiniti Q60 Project Black S details finally revealed

Despite being first revealed at the 2017 Geneva Motor Show, Infiniti has been quite coy concerning the details of its F1-inspired hybrid super coupe, the Q60 Black S. That ends at this year's Paris Motor Show, where the company has finally spilled specific information about the car. It's technologically fascinating, even if the on-paper performance doesn't sound all that shocking. Total power output of the concept, now called Q60 Project Black S, is 563 horsepower, with final torque figures yet to be announced. That power comes from a combination of the twin-turbocharged 3.0-liter V6 found in the Q60 Red Sport 400, along with a trio of motor-generator units that have similar functionality as those found in the Renault Sport F1 car's KERS (Kinetic Energy Recovery System). One large one is connected to the rear axle and generates electricity under deceleration like most hybrids, and it can deliver 160 horsepower under acceleration. The other two motor-generators are coupled to the turbochargers. They generate power under acceleration as the turbines spin. They also act as an electrical anti-lag system, spinning up the turbines when hitting the throttle again after it has been closed in order to provide maximum boost immediately. Power for and from these motor-generators is stored in a 4.4-kWh lithium-ion battery pack. All the powertrain's power goes through a seven-speed automatic transmission to the rear wheels via a mechanical limited-slip differential. The company claims it can hit 62 mph in under 4 seconds. One of the advantages of this powertrain is that electricity is generated both on acceleration and deceleration, which helps maintain battery charge so the motor assistance can be used more of the time. How aggressive the car is with the electrical boost is determined by which mode the vehicle is in, Road, Quali (for qualifying), or Race. Road is the most conservative, whereas Quali is the most aggressive. The reason for this is that if you're qualifying, you have to go the fastest you can in a short amount of time. A digital simulation of the car running a lap in Quali mode at Circuit de Catalunya estimated it would use 15 percent of the battery charge. That means it could do a little over six laps in that mode and maintain full use of its electrical assists. Race mode conserves battery life more, since you'll want that power over the course of the race. A downside to the Project Black S hybrid system is that it's really heavy.

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.
