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 NY taxi deal faces court obstacles

Nissan scored a big win for itself when the NV200 was named New York City's Taxi of Tomorrow, but the compact van has been under attack ever since. The latest setback for Nissan comes from the New York Supreme Court, which has reportedly ruled the deal between NYC and Nissan is "null, void and unenforceable" since the NV200 is not a hybrid - one of the key parts of NYC Mayor Michael Bloomberg Taxi of Tomorrow plan.
The NV200 Taxi launches this October. Although Nissan says it is bringing a hybrid version of the van to market in 2015, the New York Supreme Court ruled against Nissan, which opens the door for taxi companies in NYC to drive non-Nissan hybrid vehicles. Despite this setback, it doesn't sound like this ruling will affect the NV200 becoming the official taxi of NYC as a part of the 10-year contract worth an estimated $1 billion.

Nissan installs 1,000th CHAdeMO fast charger in Europe

While the European Union hasn't been very supportive of CHAdeMO stations, the fast chargers are seeing significant growth in the European electric vehicle (EV) infrastructure, with Nissan installing number 1,000 at the Roadchef Clacket Lane Services in Surrey, UK recently. In the past year, the number of CHAdeMO fast chargers nearly doubled in Europe, starting from about 600 stations in early 2013, and that's helping make EVs more useful. Nissan says that installation of a CHAdeMO station along Norway's E18 highway increased EV use eightfold there in the 18-month period after that station was installed. The new CHAdeMO station in the UK is available to use for free and, like other CHAdeMO stations, can charge a Nissan Leaf or other compatible EV up to an 80-percent charge in just under 30 minutes. Japanese automakers like Nissan and Mitsubishi are dedicated to the CHAdeMO but German and US automakers continue to support a competing technology in Europe and abroad, the SAE Combo DC fast charger. Tesla Motors has covered all the bases as it rolls out its $1,000 CHAdeMO adapter for its Supercharger stations. Nissan worked with Ecotricity, a UK green energy firm considered to be a pioneer in EV charging, for the Surrey installation. Nissan says that installing it on the M25 highway south of London helps EV drivers gain easy access to Kent and onward into Europe on one of the busiest roads in Europe. That will help drivers of the Leaf and the upcoming Nissan e-NV200 electric van to quickly extend their journeys, said Jean Pierre Diernaz, Nissan's director of electric vehicles, in the press release available below. 1,000th CHAdeMO standard quick charger installed in the UK UK has 18% of Europe's electric vehicle quick chargers Charger provides free, zero carbon electricity from Ecotricity Chargers recharge electric cars from 0-80% in 30 minutes Nissan has announced 1,000 CHAdeMO quick chargers have now been installed in Europe with the commissioning of the charger at the Roadchef Clacket Lane Services in Surrey, UK. The fast charging unit can recharge the batteries of compatible* electric vehicles - including the 100% electric Nissan LEAF - from zero to 80 percent charge in just 30 minutes, and at zero cost. The installation of the fastest type of chargers dramatically increases the uptake and usage of electric vehicles.
