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.

These 'blind' automotive world record stunts have to stop

Drivers setting world records "blind" – wearing a blindfold or with something obscuring the windshield – is the new thing for some reason. First it was an Alfa Romeo Giulia setting a blind lap at Silverstone with help from a spotter trailing behind, and now this: a stunt man doing a J-turn within a narrow path with nothing but a Nissan Juke's cameras guiding him. He matched the "sighted" J-turn record, flipping the car around in a space about 7 inches longer than the car. I have two issues with these stunts. First, there are just too many world records. Yeah, I said it. Are these meaningful? Is someone else likely to ever attempt this feat? No, because it's just marketing, both for the manufacturer and whoever's still trying to sell those annual books. Stuff like the fastest production car is fine with me. Heck, I'll even take unofficial Nurburgring times – the kind where the drivers can actually see. Second, I'm all for stunts, but do something cool! And preferably something that could only be performed with that particular car, if you're going to make an ad out of it. Yes, the Juke has an Around View Monitor system, which stitches together feeds from four cameras to make it look like the car is being filmed by a drone hovering overhead. I happen to love 360-degree cameras – they let you see things that are just not visible from the driver's seat and make parking and low-speed maneuvering really easy. But the Juke isn't the first car to offer one, and the feature isn't even new to the car. Nissan was at least forthright enough to admit that this professional driver (on a closed course!) had a bunch of practice. But this really says more about his precision driving skills than about the car, or the camera. And just so we're clear, you really shouldn't try to park a car without looking out the windows, even if you have fancy cameras. So what's next? Pretty soon there will be a record for blindest blind stunt. Let me know when someone actually does something interesting. Related Video:

Apple iTunes Radio picks Nissan as first automotive launch partner

With the launch of iOS 7 last week, those who carry around a certain fruit-branded cellphone got access to a new technology called iTunes Radio. Apple's delayed entry into a market currently dominated by service such as Spotify and Pandora, iTunes Radio allows users to create their own stations or to choose from a number of featured stations. From there, listeners can fine tune their results to deliver more popular songs or newer, deeper tracks. Each song is linked back to the iTunes store, allowing users to easily buy songs they fall in love with.
Now, Nissan has teamed with Apple as the exclusive launch partner for iTunes Radio. This partnership means you'll be seeing some Nissan-specific content when you're surfing through iTunes Radio, with some subtler stuff in the form of material and some not-so-subtle approaches, like Nissan's use of iAd, a system that allows developers to directly insert advertisements into apps. The focus at first will be on the upcoming Rogue, the redesigned Versa Note and the Leaf EV.
Nissan's vice president of marketing in North America, Jon Brancheau, explained the team up, saying, "We see iTunes Radio as an integral part of our new vehicle launches and 'big moments,' riding the wave of interest and usage of this exciting new service to maximize exposure of Nissan's new models." Take a look below for the rundown from Nissan.
