1992 Infiniti Q45 with under 9,000 miles is a window into the glory days of Japan, Inc.

The 1980s saw Japanese auto boom in the U.S., while at home the "Bubble Economy" of the latter half of the decade swelled corporate coffers. The heady atmosphere lead first Honda, then Toyota and Nissan, to launch luxury divisions, aimed primarily at the U.S. market. Nissan formed a secret task force in 1985 to create Infiniti, and the brand launched (simultaneously with Lexus) at the 1989 Detroit Auto Show. The Infiniti Q45 was the brand's flagship and displayed a distinctly Japanese take on the luxury sedan. Whereas the Lexus LS400 was like the world's most perfect Cadillac — all silence and smoothness — the more driver-oriented Q45 was something akin to an Asian Jaguar. The Zen-like styling eschewed luxury car cliches such as interior wood trim and a fancy chrome grille. Instead, the nose of the Q45 was adorned with a stylized badge that was suggestive of a samurai shield. When Lexus stormed out of the gate and left Infiniti far behind, Nissan's luxury division began to dial back the iconoclasm and tack toward conventionality. All of which makes this early, 1992-model Q45 a rare and intriguing machine. It's all the more representative of Infiniti's early days because of its ultra-low mileage: just 8,800 miles are on the clock. Up for sale right now on the auction website Cars & Bids, this Q45 reportedly had just one owner up until last year. It features a leather interior, power seats, a sunroof and a trunk-mounted 10-disc CD changer. Under the hood is a DOHC 4.5-liter V8 that's good for 278 horsepower and pairs with a four-speed automatic transmission to drive the rear wheels. Of note is the factory case that houses the original titanium keys. At this writing, bidding for this rarely seen Japanese luxury sedan stands at $11,000 with two days left to go in the auction. That seems a small sum for such a well-preserved totem of the Japanese auto industry's master-of-the-universe period. Related Video:

MotorWeek revisits 1990 Infiniti Q45

With the one-two punch of the Lexus LS 400 and Infiniti Q45 in the early '90s, Japanese automakers started taking the fight directly to the established V8-powered German flagships on American roads. Here, we get MotorWeek's take on the latter and probably lesser known of those luxury sedans. While not so impressive today, the Q45's 4.5-liter V8 with 278 horsepower and 292 pound-feet of torque was pretty good by the contemporary standards. The big sedan was also offered with an optional all-wheel steering system that made the model quite a capable handler. The rear end even stepped out a just little during MotorWeek's slalom. Unfortunately, styling is very polarizing with these early sedans. Where the early LS looks planted with its big, chunky lines on the outside, the Infiniti is a bit more delicate. The design just doesn't scream about being a flagship sedan. The interior doesn't help sell the car as the top of luxury, either. While MotorWeek likes some of the amenities inside, there are complains about the reused switches from the Nissan Maxima and the extensive use of plastic, rather than wood. With Infiniti now having its sights on the global premium market and soon entering the compact segment, it's fascinating to see the very roots of the brand.

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.
