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.

Infiniti Q70 adds long-wheelbase model, fresh looks for 2015

After all the work done for the Q50, Infiniti has finally given some attention to its flagship sedan, the Q70 (or, for those that refuse to use the brand's latest nomenclature, the M). While the refreshed sedan sports a few visual tweaks, the big bit of news is that it's the first vehicle in its segment to offer both long- and a short-wheelbase options (keep in mind, both BMW and Audi offer LWBs in China, but not in the US).
Infiniti has stretched the standard car's 114.2-inch wheelbase to 120.1 inches, lengthening the car 7.3 inches overall. Nearly the entire wheelbase increase is dedicated to rear-seat legroom, with a substantial increase of 5.6 inches overall. As for the effect the stretching had on the Q70's looks, well, we actually think it might look better with the longer wheelbase.
It's a nice change of proportions that is complemented by the fresh looks of the facelifted Q70. New head and taillights are the biggest changes, with full LEDs in the back and LED accents in front. There's certainly a bit of Q50 in the front, thanks to both the headlights and the new "double-arch" grille, complete with mesh-finish inserts. In the cabin, material quality looks to remain impressive, with Infiniti's cool silver-dust wood trim being shown off in the press images. Outside of that, interior changes are kept to a minimum.

Weekly Recap: Matthew McConaughey's star shines brightly for Lincoln

The commercials were a little strange at first, but the ensuing spoofs were hilarious. And all jokes aside, Matthew McConaughey has made a difference for Lincoln. Advertisements starring the Oscar winner launched in September, and the results have been impressive. The number of customers clicking on Lincoln.com to check out the MKC – the crossover McConaughey pitched – has tripled since the ads began airing, a spokesman told Autoblog. They also generated 4.4 million views on YouTube and spawned parodies by Ellen DeGeneres, Conan O'Brien, South Park and Jim Carrey on Saturday Night Live, which racked up another 15 million views. Most importantly, Lincoln's sales have increased 15 percent through November, helped significantly by the strong launch of the MKC. Without the addition of the MKC, Lincoln's sales would have been essentially flat last year. The MKC has received solid reviews from consumers and the press, though it has had several recalls. "The overwhelming response to the MKC campaign sparked truly great awareness for Lincoln," Andrew Frick, Lincoln group marketing manager, said in a statement. Now Lincoln has launched another round of spots, which kicked off New Year's Day during college football bowl games. This time, McConaughey is hawking the MKZ sedan and its hybrid sibling. The spots, called Diner and Balance, use the same artistic formula as the earlier ads, with McConaughey intoning seriously about the cars in dramatic settings. They were shot over two days in Los Angeles and were directed by Nicolas Winding Refn, a Danish filmmaker who directed the 2011 move, Drive. The ads continue Lincoln's multiyear deal with McConaughey, who has said he's been long been interested in the brand. He starred in the 2011 thriller, The Lincoln Lawyer, as a defense attorney who worked out of a Town Car, though that was before his deal with Lincoln. In one of the earlier ads, McConaughey claims: "I've been driving a Lincoln since long before anybody paid me to drive one. I didn't do it to be cool. I didn't to it to make a statement. I just liked it." That sentiment appears to have worked for the MKC's launch, and with this new advertising blitz, Lincoln hopes it carries over to the MKZ.
