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.

Race Recap: 2014 24 Hours of Le Mans defines 'endurance'

Commenting on the rush of events that rocked beginning and end of the 24 Hours of Le Mans, Paul Truswell of Radio Le Mans said "the race is about the ability to endure, not just the ability of drivers to do what they do for a long time." The entire race machine, all the way down to the pit boards and radios, has to survive the stress and abuse of the entire day. This was the race to prove those words.
There were two Toyotas, two Porsches and three Audis, five of the seven led the race at some point, six of the seven ran in the top three. Toyota will be hugely disappointed that it didn't win when its car and drivers were so, so strong, but they gave Audi the kind of scare we haven't seen since the best of Peugeot's days, and Toyota did a better job of it even in the loss. Porsche blew away everyone's expectations, falling 3.5 hours short of a fairy tale ending that would have made Disney cry.
But Le Mans doesn't really do fairy tales. Well, not that fairy tale. Audi's Twitter handle during the event was #welcomechallenges. As usual, Le Mans answered for the entire field.

Watch these Super Bowl car commercials [UPDATE]

On Sunday, February 3, the New England Patriots take on the Los Angeles Rams in Super Bowl 53 at Mercedes-Benz Stadium in Atlanta, Georgia. Some will watch because of the storyline of the old-school dynasty facing off against the new-school wunderkinds, but a large chunk of people will solely be watching for the commercials. Lucky for those who slot into the latter category, many of the manufacturers release their super bowl ads ahead of time, or have simply opted to release the commercials only online. Scroll down to see what car companies have already shown their cards. Audi Audi goes the comedic route in its clip for the Big Game. It starts with a grandpa showing his grandson a gorgeous Audi e-tron GT tucked away in a garage before he's shaken awake. Turns out he was just choking on a cashew in his cubicle at his boring job. Dodge Dodge does what it knows: create enough smoke to punch more holes in the ozone layer. Set to "The Devil Went Down to Georgia (the Super Bowl is in Atlanta, get it!?), a Challenger SRT Hellcat widebody, Charger SRT Hellcat, and Durango SRT are seen ripping through a city, leaving a trail of rubber crumbs in their wakes. Genesis Genesis has not yet released a commercial prior to the Super Bowl, but it is the official luxury vehicle of the NFL. Because of this, Genesis is hosting a fan experience for 10 days before the game. It will showcase the brand's cars, offer games, and have photos opportunities and autograph days. Hyundai Jason Bateman alert! Hyundai is one of the few companies to hook a major celebrity for its advertisement, and the casting is perfect. Bateman plays a doorman who takes people to various terrible events in life, including root canals, the middle seat, and shopping for a car. The ad centers around Hyundai's Shopper Assurance, which is Hyundai's new method for car shopping. Jeep An old 1963 Jeep Gladiator finds its strength in the crusher and transforms into a a new 2020 Gladiator, with a firm declaration that the nameplate is officially back. Kia Through Kia's commercial, a young boy wonders out loud what it'd be like if the millions spent on Super Bowl commercials were used to help others.
