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.

Nissan's Taxi of Tomorrow shut down by NYC courts [UPDATE]

Justice Schlomo Hagler may have just put a big dent in Nissan's plans to rule New York City's taxi fleets and outgoing Mayor Mike Bloomberg's vision of a unified fleet of yellow cabs.
As an October 28 deadline approached that would see all current, non-hybrid taxis replaced over by the Nissan NV200 over a three-to-five-year span, the legal battle that's enveloped the Taxi of Tomorrow program from the start has intensified. In a lawsuit, the Greater New York Taxi Association claims New York's Taxi and Limousine Commission overstepped its powers in mandating that taxi fleets are refitted with the NV200, according to the New York Daily News. This isn't the first time the courts have sided with the cabbies in the ToT debate.
Justice Hagler agreed with the cabbies, striking down the Taxi of Tomorrow purchasing requirements, and saying, "Simply stated, the power to contract and compel medallion owners to purchase the Nissan NV200 from Nissan for ten years does not exist in the City Charter," according to The Wall Street Journal.

Did Nissan send a ringer GT-R to run the 'Ring? [w/video]

It turns out that after toting a 7:08 time around the fearsome Nürburgring Nordschleife for the new Nismo-tuned GT-R, Nissan might not have been entirely honest about the car it was using. From what we've been hearing from a few different publications, the GT-R featured in the video isn't what we're going to see on the production model.
PistonHeads reported on the so-called "Time Attack" GT-R while it was in Japan for the Tokyo Motor Show, going so far as to detail the differences between it and the standard GT-R Nismo. And friends, this isn't just a matter of swapping tires. The mods made to the Time Attack car are far more comprehensive.
For a start, the TA produces more downforce thanks to larger aerodynamic pieces. It's some 110 pounds lighter than the standard car, thanks to new bucket seats. The ECU and dampers have been swapped for new units, and the brake pads are different as well. If you've read this far, you might be feeling slightly angry or betrayed that Nissan is toting numbers for a modified car. Don't be.
