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.

Meet the Nissan GT-R test driver responsible for 'Ring tuning

Ever wonder what it's like to be a manufacturer's development driver at the Nürburgring? We imagine it's pretty cool. After all, you get to spend your days zooming about the greatest racetrack on the planet in a vehicle that is usually months or more away from consumers. For Hiroyoshi Kato, whose actual title is Technical Meister, life is even better than your typical development driver, because he spends his days wringing out the Nissan GT-R Nismo around the Green Hell.
Kato-san has a long history with both Nissan and the Ring. He had a major hand in the development of the R32, R33 and R34 Skyline GT-Rs, having first come to the Ring nearly three decades ago.
His experience with the Nismo, though, is different than the other vehicles he's contributed to. As he explains it, there are real racers on hand to test the car on the track, like Formula One reserve driver Sébastien Buemi. Instead, Kato focuses on the track-to-road balance. Still, he has some truly interesting insights on the car and the track, including his surprise at turning a sub-eight-minute lap in his first outing. That, along with a few other things (one of which is an R34 being hustled about), make this a must-watch video from Nissan.

Nissan raises base GT-R price to $101,770 for 2014

Nissan has announced a few pricing tweaks for the 2015 GT-R, one of which pushes the most basic variant past $100,000 for the first time. The 2014 cost of entry was $99,590, while the 2015 GT-R starts at $101,770.
The GT-R Black Edition, meanwhile, will demand $111,510, up from 2014's $109,300. The GT-R Track Edition retains the $115,710 asking price of the 2014 car. The price increases on the base and Black Edition come with some additional goodies that should soften the blow to pocketbooks, including a retuned suspension that promises a "more sophisticated ride," while LED headlights come standard. Bose Active Noise Cancellation has also been added to the 2015 GT-R, as has a new interior color option on the base model. For a full rundown of new goodies on the GT-R, check out our original post on the 2015 vintage.
Interestingly, the destination charge for the 2015 GT-R has climbed dramatically, from 2014's $1,000 to $1,595 for the latest car. We've reached out to Nissan to see why there was such a big increase, and will update as soon as we have an update.
