Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.

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:

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.
