A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

2016 Infiniti QX50 is new and improved, kind of [w/video]

The Infiniti QX50 is, to be frank, ancient. It hit the market way back in 2007, and has labored on ever since. Through December of last year, the company only moved 2,727 QX50s. The year before, there were only 2,164 sales, and 3,495 in 2012. What do all three years have in common? The QX50 was Infiniti's slowest seller in each of them. Here's hoping, then, that this latest update will boost the 2+2 crossover's appeal. Being shown today at the 2015 New York International Auto Show, Infiniti has made a number of updates to its smallest crossover, with the most notable being a 3.2-inch stretch in its wheelbase and a 4.5-inch increase in its overall length. That makes for an enormous 4.3-inch increase in the legroom of the formerly cramped second row. Infiniti also made slight increases to the overall ride height, of 0.4 inches in for rear-drivers and 0.8 inches for all-wheel-drive variants. Outside of the dimensional changes, Infiniti also beefed up the former EX37's exterior, with new front and rear bumpers that boast SUV-like scuff plating, as well as LED accents in the new headlights and a new grille that is more in keeping with the brand's current design language. LED taillights sit out back as standard, while Infiniti will happily sell consumers an optional xenon headlight package. Infiniti may have updated the exterior, but the cabin looks largely unchanged, aside from the extra space in the second row. It looks like a complete carryover in terms of features, trim and general layout. Also unchanged is the QX50's 3.7-liter V6 engine. Output remains fixed at 325 ponies and 267 pound-feet of torque. Regardless of whether power goes to the rear or to all four wheels, a seven-speed automatic is in charge of managing the power. We'll have more on the freshened QX50, including live images, coming soon from the floor of the 2015 New York Auto Show.

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.
