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:

2018 Infiniti Q60 Red Sport 400 Quick Spin Review | Beauty before brawn

The 2018 Infiniti Q60 Red Sport 400 is an absolute beauty in person. And that's important, because, more than any other segment in the automotive marketplace, a personal luxury coupe has got to have the kind of attention-grabbing looks that can lead off the discussion about a brand-new vehicle. Like this one. It's also important because the name Red Sport 400 conjures up a kind of performance imagery that the Q60's hardware doesn't quite live up to. But before we delve into the world of horsepower and torque, let's finish talking about style. Like most luxury marques these days, Infiniti is working really hard to put a variant of its instantly recognizable corporate face on everything it sells. Unlike some other automakers — *cough* Lexus *cough* — Infiniti has been mostly successful in the styling-led marketing push without making each new car a caricature of the model it replaced. The fascia is dominated by a curvaceous chrome grille, which has little wing-shaped tabs that draw attention toward a dashing pair of headlights. These lighting units have LED elements that sort of form the shape of eye makeup, and while that could be a major styling misstep, it looks lovely on the Q60. Moving back from the face, there isn't a flat surface anywhere that might distract an onlooker from the overall cohesiveness of the design. The Q60's sheetmetal is pulled, pushed, and bunched like taffy strung across a whirling pair of beaters. If we were to lodge a complaint about the Q60's appearance, it would focus on the superfluous chrome-tipped gill slits just behind either front wheel and the too-small displacement badge nearby on the fenders. Both of these bits are unnecessary and seem like they were tacked on at the last minute. But those are small grievances that don't do much to distract from an otherwise cohesive design, and the chrome vents can be replaced with carbon fiber for an extra $395. It would be a sin to choose any color other than Dynamic Sunstone Red. This deep shade suits the Q60's flowing lines perfectly, and everyone who saw the car parked in our driveway had good things to say about the hue. Other colors are available, but ... just pick the red. The interior of out test car had seats in an off-white shade of leather that looks good, but was already showing wear and discoloration. We'd probably choose the red leather seats instead.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
