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.

NYC Taxi of Tomorrow ruled legal by appeals court

The streets of New York City might be filling up with a lot more Nissans in the next few years. A New York appeals court ruled that the city's mandate to replace old taxis with a fleet entirely made up of the Nissan NV200 Taxi of Tomorrow was legal. The decision overturned a previous ruling that decided The Big Apple couldn't force cabbies to all purchase the same vehicle.
Justice David B. Saxe wrote the court's opinion saying the Taxi of Tomorrow is a "legally appropriate response to the agency's statutory obligation to produce a 21st-century taxicab consistent with the broad interests and perspectives that the agency is charged with protecting," according to Bloomberg. The Greater New York Taxi Association, the plaintiff in the case, could still possibly attempt a second appeal.
Nissan originally won the 10-year contract estimated to be worth about $1 billion in 2011, beating out Ford and a Turkish company. Under the Taxi of Tomorrow plan, all New York cabbies would have to switch to the NV200 within three of five years of the van going into service, and it would replace the 16 vehicles previously authorized as taxis. In 2013, the mandate received multiple challenges though, including an attempted ban by cab drivers because the replacement wasn't a hybrid. In a separate case, state Supreme Court judge Schlomo Hagler decided that there was nothing in the city charter that forced a taxi driver to choose a specific vehicle. This was the case that was just overturned. In the meantime, the automaker has been selling the NV200 to New York cabbies at prices around $29,700.

Who knew a 1,200-hp GT-R could be so lovely?

The proliferation of 4K cameras and displays is bringing the world some utterly fantastic automotive videos. If you like seeing Jeff Zwart powering up the Pikes Peak course in high-def glory but wish for some hugely powered Nissan GT-Rs in place of the turbocharged Porsche, then this clip shouldn't be missed. Japanese magazine Motorhead brought together a 1,200-horsepower, HKS-tuned R35 GT1000 and an earlier R32 GT-R Group A racer to send them through a tight, mountain road. The clip uses an augmented reality aesthetic to place little pieces of info about the car, driver, and emotions over the scenes, while the coupes are blasting through the forest. The real highlight here is the cinematography and sound. Turn up your speakers to get an earful of the GT-R's gasoline-fueled heart. The cameras mounted on driver Nobuteru Taniguchi turn the world outside the car into an impressionistic blur of green as the trees smear together at such high speeds. The combination of sight and sound offers a fantastic sense of speed. The only, tiny problem with this clip is that the preamble before the coupes thunder off is just a bit too long. If you need an extra minute in your day, skip straight to 1:15 to get immediately to the action. Although, missing the beginning means not seeing an inky black GT-R driving through the Japanese night. According to Speedhunters, the video is meant to promote the theme for Motorhead's latest issue – Japan Tuned. The magazine apparently comes even more video of the two cars playing on the mountain.
