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.

Q50 Eau Rouge to kick off series of performance Infinitis

Infiniti is desperate to position itself as a brand for performance enthusiast. It's tried to create that impression by attaching its name to the Red Bull Racing team, by sprucing up the G37 Coupe and G37 Convertible as part of its lack-luster Infiniti Performance Line, and by bringing Sebastian Vettel on board to create a special edition FX crossover. But the Japanese luxury brand knows it's going to need something more comprehensive if it's going to go up against BMW and its M models, Mercedes and its AMGs, or Audi and its Quattro GmbH-tuned RS range.
That's why the Q50 Eau Rouge concept unveiled just last week at the Detroit Auto Show was so important to the marque. But Infiniti has more in store than just a concept. Nissan desires to put the Q50 Eau Rouge - named after the notoriously challenging turn at the Spa Francorchamps circuit in Belgium - into production with a 500-horsepower engine. But in speaking to Automotive News, Infiniti chief Johan de Nysschen hinted at more good news to come.
That could include a performance version of a new flagship sedan Infiniti is said to be working on, positioned above the current Q70 to fill the void left by the discontinued Q45 that capped the brand's range before it shifted its entire naming scheme behind it. The flagship sedan would need some serious muscle to challenge the likes of the Mercedes S63 AMG and Audi S8, but Infiniti seems bent on getting there. To cap it all off, Infiniti has long been rumored to be working on a halo sports car. Whether they'll all carry the Eau Rouge name, the IPL badge or some sort of other designator remains to be seen, but we'll enjoy seeing this development progress.

Infiniti to launch first electric car, to be made in China

BEIJING — The first electric car for Nissan's premium brand Infiniti will be a sporty sedan produced in China, the Japanese carmaker said in a statement viewed by Reuters ahead of a public announcement expected as soon as Wednesday. The vehicle would hit the market in around three years, and consumers would get a taste when the company unveils a concept car, dubbed the Qs Inspiration electric sedan, at the Shanghai auto show later this week, Nissan officials said. "China has the most growth potential for electric vehicles globally, especially in the premium segment," Infiniti Chairman Christian Meunier said in the statement seen by Reuters. Automakers operating in China have to sell more so-called new-energy vehicles, either battery electric cars or plug-in electric hybrids, to comply with official production quotas designed to reduce smog. It was not immediately clear whether Infiniti planned to produce its first electric vehicle in other markets. An Infiniti spokesman said, however, the brand did not intend to export the e-sedan from China. The planned e-sedan is part of Infiniti's longer-term strategy to significantly electrify its product lineup. Brand officials have said that from 2021 every Infiniti model launched will be either an all-electric car or so-called "e-Power" hybrids, underlining Nissan's previously announced plan to make Infiniti primarily an electrified offering. The sedan likely would be built on a new flexible architecture developed specifically to accommodate electrified powertrains, Infiniti said in the statement. Its design, especially the interior, would be significantly different than current models, design chief Karim Habib said. EVs do not have bulky gasoline engines and transmissions, opening up space inside the car. "It will have a flat floor, and if you are a passenger you can cross your legs or stretch out your legs," Habib told Reuters. Competition in China's rapidly emerging electric car market is heating up amid an onslaught of models from startups such as Nio and WM Motor, as well as those from established automakers. In the luxury segment, Infiniti will be competing with Tesla Model S and Model X, as well as other models due to be launched in coming months by Audi, Mercedes-Benz, BMW and Lexus.
