Infiniti's variable compression engine in the 2019 QX50 is the first of its kind

The world's first variable compression ratio engine is here, in a production car. That car is the 2019 Infiniti QX50, debuting this week at the Los Angeles Auto Show. The midsize crossover has seen a refresh that has brought it an all-new platform together with new driver assist features, but it's the engine that's the centerpiece here. Nearly everything is continuously variable under the hood of the QX50 – not only the new shift-by-wire XTRONIC CVT. The new VC-Turbo gasoline engine is able to change its compression ratio from 8:1 to 14:1, or anything in between depending of the driving situation; whether there is need for top-end power or turbodiesel-like torque from low revs, or optimized fuel economy. The pistons' reach is continuously adjusted by an electric "Harmonic Drive" motor, which controls a multi-link system, affecting the top-dead-center of the pistons and changing the compression. The engine can also switch between efficiency-maximizing Atkinson cycle and regular combustion cycle, on the go – and there's both multipoint injection and gasoline direct injection employed. The result is 268 horsepower at 5,600 rpm and 280 pound-feet of torque at 4,400 rpm; good figures for a 2.0-liter four-cylinder gasoline engine with a single-scroll turbocharger. Infiniti says that the FWD version's fuel economy of 27 miles per gallon combined is 35-percent better than the previous-generation V6 engine; in AWD guise, it reaches 26 mpg, which is a 30-percent improvement. The new engine is pretty much all-aluminum, but the vaguely magical-sounding "transformative multi-link components" behind the variable compression system are made from high-carbon steel alloy. The engine's multi-link system also enables it to do away with any balancing shafts, and Infiniti compares its smoothness to a V6 rather than a regular four-cylinder. In addition to the aforementioned tech, the VC-Turbo engine has the world's first active engine mount vibration damping system to smoothen its operation even further. Related Video:

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.

Infiniti announces pricing for 2014 QX60 and QX70

With the exception of the G37, customers walking into Infiniti showrooms this summer are going to see a bunch of different names pop up as the automaker switches to its new Q-for-car and QX-for-crossover/SUV naming convention for 2014. The first of these renamed models are the 2014 QX60 (which replaces the JX) starting at $41,550* and the 2014 QX70 (which replaces the FX) priced at $44,950* (*prices do not include $995 for destination), and both are on sale now.
Compared to the outgoing models, the new QX60 (seen above, click to enlarge) lineup starts $300 more than the outgoing JX models (base and AWD), while pricing for the QX70 will remain the same as the trio of 2013 FX models (FX37, FX37 AWD and FX50). What is still unclear is how much the all-new QX60 Hybrid model will cost or how much option and package pricing will change, if any. Scroll down for more info on the new QX60 and QX70 crossovers.
