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.

Nissan bringing Infiniti brand to Japanese market

Ever hear that the best stuff is saved for export? Just ask Japanese luxury car buyers. It's been decades since Japan's largest automakers set out to take on Europe's finest with dedicated luxury brands of their own, but they have kept those brands largely out of their own domestic market and sold them almost exclusively overseas. But that's beginning to change.
In 2005 Toyota launched the Lexus brand - which it had been exporting since 1989 - in Japan. Honda reportedly planned on bringing its Acura brand to its home market just a few years later, but ended up delaying the move. Now Nissan is reportedly preparing to launch the Infiniti lineup in its own backyard.
This according to a report published in the Japanese business daily Nikkei and now making the rounds of the English-language press. The plan apparently involves offering at least part of the Infiniti model line in domestic Nissan dealers, holding off for the time being on launching a separate dealer network in Japan.

Infiniti showcases Vision Gran Turismo concept in the metal

Automakers have been clamoring to convey their ethos to a new generation and cast their brand in a positive light through the Vision Gran Turismo series. But while these concepts are designed for the virtual reality of Gran Turismo 6, some automakers have gone a step further by pulling their creations out of cyberspace and rendering them in the metal. And that's just what Infiniti has done with its design. Infiniti revealed its Concept Vision Gran Turismo back in December, striking a a sleek, low-slung form that looks more polished than a racing car but more track-focused than most concepts. It's powered (at least hypothetically) by a 4.5-liter V8 hybrid powertrain, with center-lock carbon-fiber wheels and rearward-biased 45/55 weight distribution. It's the kind of beast we'd love to drive, but while that may only be possible on Playstation, at least we know it does exist in physical reality – even if only as a full-scale model. Infiniti showcased it alongside the Q80 Inspiration and Q60 Concept at an exclusive event during the Shanghai Motor Show last week, but just revealed the photos now, so you can scope them out in the slideshow above.

Under the theme of "Aesthetics of Contrast," Infiniti Design Night showcased three design concepts showing an exciting path to Infiniti's future: the Q80 Inspiration (first shown in Paris, October 2014), Q60 Concept (Detroit, January 2015), and the Vision Gran Turismo designed especially for the latest Gran Turismo® 6™ video game. This was the first time the Vision GT was displayed as a real "flesh and bones" concept car, having only been seen and experienced digitally in GT6 prior to this event. The dramatic Infiniti Concept Vision Gran Turismo The Infiniti Concept Vision Gran Turismo is a vision of what a high performance Infiniti could look like in the future. Available for download in GT6 exclusively on the PlayStation®3 system, it was created through close collaboration with the creators of Gran Turismo®, the racing game franchise developed by Polyphony Digital Inc. that has sold more than 72 million copies worldwide.
