Infiniti introduces Q70 Premium Select Edition to Monterey crowds

Infiniti has made its presence at the 2015 Monterey Car Week known, introducing a new version of its flagship sedan, the Q70. As far as special editions go, the new Premium Select Edition Q70 is fairly light on upgrades, going for minor aesthetic tweaks rather than rocking the boat too heavily. Unsurprisingly, one of the most obvious changes is down low, where Infiniti's stylists have fitted new 20-inch wheels. The gunmetal hoops are joined by dark chrome trim on the fascia, a new rear bumper, and a decklid spoiler. Buyers have the choice of two interior trims. There's Graphite and Stone, both of which feature semi-aniline leather, a "suede-like" headliner, and aluminum interior trim pieces. Infiniti isn't too picky when it comes to powertrains for the Premium Select Edition, although there are some restrictions. It can be had with both the 3.7-liter V6 and 5.6-liter V8 and in rear- or all-wheel-drive models. Weirdly, though, you can't get the stylish trim on the Q70 Hybrid or on long-wheelbase models. We can't tell you how much it'll cost to add the special-edition trim, because Infiniti did not deign to release pricing info. We can, however, tell you that the Q70 Premium Select Edition will hit dealers this November. Look for more, including live images of the new sedan, as the Monterey Car Week continues. Until then, scroll down for the official press release.

The specially equipped Q70 premium sedan will be available at Infiniti retailers nationwide beginning in November. "Following the introduction last year of the new Infiniti Q70 long-wheelbase model, we are continuing to expand our flagship Q70 sedan's portfolio of offerings," said Randy Parker, vice president, Infiniti Americas. "The new Premium Select Edition package gives the Q70 an extra touch of premium elegance that is right at home here at Pebble Beach – or in any neighborhood or driveway across the country." The Q70 Premium Select Edition's exterior offers dark chrome trim, a darkened lower rear bumper, a rear decklid spoiler and unique design and color 20-inch aluminum-alloy wheels with 245/40R20 all-season performance tires.

Infiniti's QX50 Concept debuts in oh-so-close-to-production form in Detroit

Infiniti debuted the new QX50 concept today at the Detroit Auto Show, a preview of the midsize crossover set to hit the market soon and an evolution of the 2016 QX Sport Inspiration. This previews the followup to the current QX50, which debuted way back in 2007 as the Infiniti EX. The QX draws on Infiniti's current design language and looks like a slightly shortened version of the larger QX60. While this is still a concept, don't expect the full production version to stray too far from what we see here. Infiniti's press release is full of phrases like "driver-centric, passenger-minded" design, but in reality it's just a handsome but mostly traditional shape. The big news is that the QX50 will be the first application of Infiniti's trick variable-compression 2.0-liter turbocharged inline four. The engine's design promises both high horsepower and high fuel economy. Infiniti is claiming 268 horsepower and 27-percent better fuel economy when compared to the outgoing model.

While the details on both are extremely vague, Infiniti claims that the autonomous tech will allow the driver to retain ultimate control over the vehicle. That seems a bit counter to how autonomous driving works, so it will be interesting to see how the system actually functions. The active safety systems are said to be proactive, with future versions using lasers, radar, and cameras. While the outgoing QX50 was a rear-wheel-drive swoopy crossover, this new model appears to send power to the front wheels. Infiniti's release doesn't expressly say, but it does hint towards it with notes about a shorter hood and a "front-biased intelligent all-wheel drive system." This makes sense, and we don't see many enthusiasts lamenting the loss of a dated, rear-drive crossover. No word on pricing or when we'll actually see a production version. The current model turns 10 this year, albeit with a mid-cycle refresh. Look for news of a final production version very soon. Related Video: This content is hosted by a third party.

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.
