New details emerge on Inifiniti QX50’s unique new variable-compression engine

Infiniti will release the world's first production variable-compression engine when it releases the 2019 QX50 midsize SUV sometime next year. Now we have some new details on the innovative new engine, which Infiniti is calling VC-T, for Variable Compression Turbo, after the luxury brand offered a prototype test drive. We wrote extensively about the complicated technology underpinning the new engine last year. It's the latest novel development that could represent a range-extender, if you will, for the embattled internal combustion engine in an era when automakers and governments are shifting their focus to electric vehicles. The VC-T is a new inline-four, 2.0-liter that combines the power of a high-performance turbo gasoline engine with the torque and efficiency of an advanced diesel engine, but without the latter's notorious emissions. It features the ability to seamlessly raise or lower the stroke of the pistons in the combustion chamber, depending on the driving conditions it detects and inputs from the driver, to select the best compression ratio—anywhere between 8:1, typical for high-performance engines, and 14:1 for high efficiency. In essence, it delivers the performance of a V6 but is much more efficient, with improved fuel efficiency of between 10 to 15 percent with its best competitors, per Car and Driver.

It's also quieter, more lightweight and compact than V6 engines with comparable power outputs, estimated at 268 horsepower and 288 pound-feet of torque. In a prototype test drive, Car and Driver writes that the engine "felt very conventional" and responsive, with strong and smooth acceleration. "The only indication you have that the compression ratio is changing is from an indicator in the instrument cluster next to the boost gauge." The engine is expected to deliver fuel economy gains of 27 percent in combined city-highway EPA rating over the outgoing QX50, which had a 3.7-liter V6. The 2019 model, fitted with the VC-T, should get about 26 mpg in combined fuel economy, and it will get to 60 mph almost one second faster than its four-cylinder counterparts, Nissan's chief powertrain engineer, Shinichi Kiga, told Automotive News. The VC-T engine is the result of 20 years of development spanning more than 100 prototypes and around 300 patents at Nissan.

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.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.
