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.

Nissan Leaf sells 1,553 in April, Volt climbs to 905

After three months in the 500 and 600 range, sales of the Chevy Volt climbed to 905 in April. That's up for the year so far – likely due to increasing discounts – but still down 41.5 percent from April 2014. As we've been saying every time the Volt turns in less-than-exciting monthly sales numbers, we suspect a large number of potential Volt buyers are waiting for the next-gen model to arrive in the second half of 2015. While the price for that car has not yet been announced, the updated tech specs show that it will probably be worth the wait for drivers who want the latest and greatest. Over on the Nissan Leaf side of things, April sales were 1,553 units this year. That's the second-best month of the year but down from the 2,088 units sold last April. After the Leaf finally climbed to the top of the cumulative best sellers list for plug-in vehicles last month, the difference between these two leaders is now 1,824 in favor of the Leaf. Nissan says that sales were influenced by the launch of its No Charge To Charge promotion in Indianapolis and Fresno, CA. This deal gives new Leaf buyers and lessees two years of no-cost quick charging in these markets. No Charge To Charge is not available in 15 US markets for (San Francisco, Sacramento, San Diego, Seattle, Portland, Nashville, Phoenix, Dallas-Ft. Worth, Houston, Washington, DC, Los Angeles, Chicago and Atlanta) and will expand to 10 more by the middle of this year. As we do every month, our full wrap-up of US green car sales is coming soon.
