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 Leaf electric vehicle goes on sale in Mexico

Nissan chief Carlos Ghosn may not be intimately familiar with the Dean Martin 1962 classic South of the Border, but he may as well start crooning the standard now. The Japanese automaker said this week that the Nissan Leaf will officially be the first mass-produced battery-electric vehicle to be sold in Mexico. So break out the horn section. Nissan will start selling the Leaf through its Mexico City dealership network and is touting features such as the car's fast-charging port. That feature allows the car to be 80-percent charged in about a half hour. Nissan and the Mexican government are also working on an "electric corridor" of charging stations between Mexico City and Cuernavaca, which is about 55 miles to the south. There will also be "charging zones" in various districts throughout Mexico City, making it easier for the newly inaugurated EV drivers to charge up in town. Nissan has been working on Leaf brand exposure to Mexico City for years, sending the first batch of 100 all-electric Leaf taxis to Mexico starting in the fall of 2011. Last month, Nissan had its best ever month of sales in the US, moving 3,117 Leafs in May and the company has sold over 115,000 Leafs around the world. Check out Nissan's press release below. Nissan becomes the first company to sell a 100% electric vehicle in Mexico Nissan LEAF arrives in Mexico and becomes the first 100 percent electric vehicle to be comprehensively marketed in the country. The car of the future is already part of the present with more than 115,000 global sales. Nissan, the leader company in electric vehicles, strengthens its commitment to promote Zero-Emission mobility by opening charge centers distributed in Mexico. MEXICO CITY – Nissan today announced the launch of LEAF, the first 100 percent electric vehicle to be marketed in Mexico. The presale starts today and will continue until its arrival on June 30. Nissan LEAF is the first zero-emissions vehicle marketed in Mexico, confirming the leadership and the promise of the Japanese company to transform traditional driving into a new silent experience. "Nissan LEAF is a reality in the Mexican market," said Airton Cousseau, CEO of Nissan Mexicana. "We are proud to be the pioneer company to introduce the first zero-emissions vehicle leader in sales worldwide in Mexico.

Kaz and Shiro talk Gran Turismo 7 details, Titan Nismo and more in AMA

One of the greatest innovations to come about thanks to the gigantic popularity of Reddit is the Ask Me Anything (AMA) question and answer format. The AMA becomes especially worthwhile, of course, when the person(s) answering the questions have detailed information or insight on products we love.
So, in the case of the recent AMA session with Gran Turismo creator and mastermind Kazunori Yamauchi (above), and his buddy and Nissan chief designer Shiro Nakamura (right), it was basically must-read stuff.
The pair really lived up to our expectations, too, with Kaz offering a lot of useful information about the future of the Gran Turismo franchise (especially the upcoming GT7 for Playstation 4), and Shiro promising to bring some interesting new ideas back to his colleagues at Nissan.
