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.

US-built Infiniti Q50 engines to go into Euro-only cars

Back in March, Infiniti announced that it would be adding a 2.0-liter, turbocharged four-cylinder to its Q50 line for European and Chinese buyers. Now, we know where that engine will be built.
Nissan's Decherd, TN facility will receive the $319-million investment, which will see a separate, dedicated line for the Infiniti engines. According to Automotive News, this is more than a line running alongside the Nissan operations - the Infiniti facility will sport its own unique architecture and interior lighting, in a bid to distinguish the premium line from its mass-market parent company.
The logistics of all this do seem, on the surface, quite screwy. Building a new engine on one continent for a car built on another that will eventually go on sale on a third doesn't seem too bright, although there is a catch here. The new engine will also find its way into the Mercedes-Benz C-Class, which will kick off production in Vance, AL later this year.

Infiniti electric crossover will mark a milestone at Detroit Auto Show

In November, it was announced that both Nissan and Infiniti will display EV concepts at the 2019 North American International Auto Show in Detroit, taking place in January. Previously, it wasn't made clear what kind of vehicles they would be, but Infiniti stated today that its Detroit concept will be an electric crossover. Both the Nissan and Infiniti concepts will continue the design direction shown by Infiniti's Q Inspiration concept, and later next year, there will be stylistically similar cars shown at the Tokyo Motor Show in October. The luxury brand has released the above teaser photo of the crossover, depicting sharp headlights and a lit grille outline surrounding the badging. We can also see large wheels and tires and sizeable, defined wheel arches. Future Infinitis will be electrified from 2021 on, featuring either serial hybrid tech or full electric drivetrains. Serial hybrid refers to using Nissan's e-power technology, which relies on range extender engines instead of a large combustion engine (such as Infiniti's lauded VC-Turbo). The Detroit Auto Show is also a significant event for Infiniti, as the brand and its first car, the grille-less Q45 luxury sedan, was first displayed 30 years ago at the 1989 NAIAS. "Thirty years ago, as a 24-year-old designer in the audience, I saw the birth of Infiniti in person and am proud to be part of the journey of creating iconic luxury automobiles," said Nissan's senior vice president for global design, Alfonso Albaisa. Meanwhile, Infiniti's November 2018 sales were the best November numbers in the brand's history. "The concept car we will show in Detroit is the beginning of a new era for Infiniti, and an illustration of where we want to go with the brand," said Karim Habib, Infiniti's design director. Earlier, Albaisa echoed his statements, telling us how electrification can inspire the brand's future design thanks to the battery packs' size development, saying: "It's getting denser, it's getting thinner, the cars are able to get a little bit bigger, more space, we can really do much more."
