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.

Google's new Android Autos OS unveiled, will be in cars this year [w/video]

Connected cars are coming en-masse. We know this much. How, though, remains something of an open question, especially as two of the world's largest tech companies are preparing to battle for control of your car's dashboard. On the one hand, we have Apple and its CarPlay system. And now, we know what Google has been working on with Auto Link.
Its new name is Android Auto, and yes, it's based off the Android architecture that is the primary challenger to Apple's iOS mobile operating system. Announced at Google's I/O conference today, Android Auto functions similarly to CarPlay - owners will need to plug their smartphones into their cars to access the full breadth of capability.
In Android Auto's case, that means a wealth of voice controls to limit distracted driving. Google's marquee apps will be available when the interface arrives in production models later this year, including Google Play Music, Google Maps and voice-activated texting and text playback. Meanwhile, developers will be able to begin designing custom apps for the new system via an upcoming software development kit.

Nissan prices limited-edition 2014 GT-R Track Edition from $115,710*

Nissan has released its pricing for the model-year 2014 GT-R, including the new Track Edition of Godzilla. The 2014 Nissan GT-R Premium will now command an MSRP of $99,590, while the Black Edition will go for $109,300 and the new Track Edition will ask $115,710 (*not including a $1,000 destination and handling charge for all models).
Nissan calls the GT-R Track Edition its most exclusive model, which makes sense as it will be limited to just 150 examples for the US market. The competition-ready Track Edition gets Bilstein DampTronic shocks and revised spring rates; all chosen after more development work by Nissan engineers at the Nürburgring. (Good work, if you can get it.) A carbon fiber rear spoiler and six-spoke black wheels come with the package, as do blue-trimmed, high-grip front seats inside. To save weight, the car's rear seats have been deleted in this model.
