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.

2014 Nissan Dayz Roox is the littlest high-roof van you ever did see

Even average production cars from Japan often seem very conceptual to US eyes. Throw in typical, nonsensical-quasi-English-words name like "Dayz Roox" and you'd be forgiven for thinking this Nissan box on wheels was still a designer's dream. But the fact is that the Nissan Dayz is a model currently on sale, and this Roox version is the latest take on the micro-van, which is a popular segment in Japan.
In fact, this generation of Dayz is the first minicar that Nissan has developed completely in-house, and the thing has been selling astoundingly well in its first stint on the market (30k units in month one month, says Nissan). So it's unsurprising that the company is looking to expand the range with a model that is more fully featured.
The Roox (we have no clue as to where that name came from, or what it means) would appear to be a high-roof version of the three-cylinder Dayz minicar - in fact Nissan goes so far as to call it an "Impressive Super Height Wagon." Features like automatic sliding doors, Around View Monitor and UV-insulated glass are all luxuries in kei-class car. The press release also specifies that the Roox is tall enough to swallow a 27-inch bicycle.

Indie rockers Local Natives perform from back of Nissan Rogue

Most bands go through a fairly simple trajectory of vehicles to make it to shows. When they form, it's all about just getting to the gig and anything works. As they build a following and start touring a little regionally, they upgrade to a van to fit all of the members and equipment. Finally, if they taste big time success, they move to the tour bus. However, indie band Local Natives is taking an interesting detour from that path in a new promotion from Nissan called Off the Stage for the Rogue.
The members show up to the middle of nowhere in a pair of the CUVs, and in a few minutes the vehicles are set up to be the group's sound system and its stage. This promo also acts as a video for the song Breakers, which is a bit of a slow jam, but the scenery is absolutely beautiful. Scroll down to watch the Local Natives turn the Rogue into a place to perform practically anywhere.
