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.

Infiniti hires Sebastian Vettel as Director of Performance

Remember when, during the Grand Prix of the Americas weekend last November, we told you that Sebastian Vettel had worked with Infiniti on the new G Coupe and that there'd be more of that kind of involvement on the way? It's been made official with the three-time Formula One World Champion being named Infiniti's Director of Performance.
Although the announcement is fresh, Vettel's time on the job isn't, Infiniti saying that Vettel went to Japan, the Nürburgring and the Circuit de Catalunya to assist in the development of the Q50 sedan.
When we spoke to Andreas Sigl, the man in charge of Infiniti's F1 collaboration with Red Bull, about the tie-up he had also said, "Like Mercedes has AMG and BMW has M - whether it's called IPL or not - we want to have something in that space." If the brand is still serious about that, Vettel's chops could help them deliver the kind of performance they'd need as upstarts to challenge the ringleaders of that particular hi-po circus.

Interest in an Infiniti EV is muted, to say the least

More than a quarter-million people have bought an electric vehicle from the Renault-Nissan Alliance. When it comes to Nissan's Infiniti luxury nameplate, though, there's not a lot of confidence. The Alliance doesn't have much hope that the badge will add to that total anytime soon. So says Emirates 24/7 in its report that Infiniti is planning on opening two showrooms in Abu Dhabi. Models such as the QX80 SUV, the Q70 sedan, and the Q50 will be shown off to those looking to live the high life, Infiniti style. But company executives told the publication that no battery-electric Infiniti models would be in the works until at least the end of the decade? The reason? Lack of demand. It's a far cry from three years ago, when a concept version of the Infiniti LE electric vehicle was shown off at the New York Auto Show. The model boasted 134 horsepower and 240 pound-feet of torque as well as wireless-charging capabilities. It was about the size of the Infiniti G sedan. At the time, the automaker's executives were estimating that car would hit the market by 2014. Those plans didn't come to fruition, obviously. As for the Alliance, Renault and Nissan celebrated the sale of their 250,000th electric vehicle this past summer. And while the lion's share of those were in the form of the Nissan Leaf, the 250,000th vehicle was actually a Renault Zoe that was bought by a computer engineer in Bordeaux, France. That's a long way from the UAE, and a long way from an Infiniti EV.
