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.

2015 Nissan GT-R Nismo priced from $149,990* [w/videos]

Remember when they called the Nissan GT-R a supercar-slayer? You can drop the "slayer" part, because the Japanese brute known as Godzilla has long since grown from an ankle-biter nipping at the heels of giants to a giant in its own right. And if that's the case with the "basic" GT-R, it's certainly the case with the new GT-R Nismo.
While the base price for the GT-R has breached the six-figure mark, the Nismo version has just been priced ten bucks shy of $150k. Factor in the $1,595 destination charge and you're looking at a $151,585 sticker price. That may seem like a lot for a Nissan, but bear in mind what you're getting for all that scrap: the GT-R Nismo's 3.8-liter twin-turbo V6 has been optimized to deliver 600 horsepower and 481 pound-feet of torque to all four wheels.
We've yet to see official performance stats, but considering that the base GT-R hits 60 in 2.6 seconds with 55 hp and 18 lb-ft less muscle, the Nismo version ought to teach a lesson or two to exotic supercars costing twice or even ten times as much. Just check it out in the videos and press release below.

Updated Nissan Micra gets fresh look, more tech and 'New' name

A few months ago, Nissan gave the Micra (which is not for US consumption) a substantial styling update that included new front and rear fascias, and stuffed more technology into the interior, such as USB ports and auxiliary inputs for audio and a new media touchscreen. Though it's still based on the same fourth-generation architecture, Nissan now calls it the New Micra.
Overall the New Micra - also known as March in some markets - looks similar to but more taut than the vehicle that launched in late 2010, thanks to more angular headlights, a new bumper, a sculpted hood and a revised grille with the Nissan logo sitting inside a chrome V, which establishes a stronger link to Nissan's "corporate look." The rear end receives less-drastic changes, such as a new bumper, LED taillamps and a new infill panel at the bottom of the tailgate.
