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.

FCA scion John Elkann tries to pull off a Marchionne-sized merger

MILAN, Italy — When John Elkann lost his ally last year with the sudden death of Sergio Marchionne, some questioned whether the softly-spoken scion of the Agnelli clan would be able to emerge from his shadow to ensure Fiat Chrysler's future. But New York-born Elkann, who became Fiat chairman in 2010, acted decisively to fill the vacuum left by the larger-than-life Marchionne and get closer to the big merger deal the legendary executive was unable to deliver. At just 28, Elkann was thrust into the role of Fiat vice chairman after the deaths of his grandfather and great-uncle "because there was really nobody else" to take the wheel. For Elkann, who got his first taste of the car industry as an intern at a factory producing headlights in Birmingham, England, the first 18 months with responsibility for the family-owned carmaker and its long heritage were "terrible." But from that low point, Elkann, 43, is now trying to merge Fiat Chrysler (FCA) with French rival Renault to form the world's third largest carmaker and tackle new challenges facing the industry. Elkann will become chairman of the merged FCA-Renault if the deal goes ahead, ensuring the Agnelli dynasty plays a central role in the next chapter of automotive history. At an event in Milan on Monday, the usually-shy Elkann looked happy and confident. His first big break came with an instrumental role in persuading Marchionne, who was running one of the businesses owned by the Agnelli family, to become chief executive in 2004 and give Fiat "a new start," Elkann said in a "Masters of Scale" podcast last year. Fiat was at the time almost on the brink of collapse. This involved a "very long night ... and many grappas" but proved to be a turning point in the fortunes of the Italian company founded by Elkann's great-great-grandfather Giovanni Agnelli, which built its first car in 1899. In 2005, Elkann backed Marchionne in negotiating the breakup of an alliance Fiat had entered into with General Motors in 2000, receiving $2 billion from GM in return for canceling a deal that could have required GM to buy the remainder of Fiat Auto. Marchionne then used GM's money to fund a turnaround at Fiat, which involved taking the Italian carmaker into a transformation alliance and then full-blown merger with U.S. automaker Chrysler as Elkann agreed to the Agnellis loosening their grip.

2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo

The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff.  Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).
