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.

Semi-autonomous Nissan Leaf certified for road use in Japan [w/video]

In order to meet its goal of having an autonomous car in production by 2020, Nissan is going to have be able to test its technology in real-world driving conditions. For this, the automaker has just received a license plate to legally test its semi-autonomous driver assist systems in Japan, marking the first time such technologies have been tested on that country's roads. Not ironically, the license plate number is 2020.
Though not fully autonomous, this Leaf prototype will test various components of a self-driving car including exiting the highway, the ability to stay in its lane and change lanes when needed, stopping at red lights and overtaking stopped or slow traffic. Nissan is also in the process of building a proving ground in Oppama, Japan dedicated solely to autonomous cars, but the ability to test on public roads will obviously play a crucial role in the development of these cars. Scroll down for a short video and press release Nissan posted to mark the occasion.

Nissan Rogue gives brand rare monthly sales lead over Honda

The five top-selling brands in the automotive industry are usually Ford, Toyota, Chevy, Honda and Nissan, in that order. This lineup emerged intact when counting a year's worth of sales for 2013, and there was no reason to expect it would change at the beginning of 2014. But it did. Thanks to surging sales of its all-new Rogue, Nissan managed to pull ahead of Honda to become the fourth best-selling auto brand in January 2014, selling 81,472 units (an increase of 10.41 percent compared to January 2013) to Honda's 80,808 (a decrease of 3.96 percent).
The Rogue led the way for Nissan, contributing an additional 4,880 units in January compared to the same month last year - a 54.5-percent increase for a grand total of 13,831 units. But the Rogue had help, with the Frontier pickup adding an extra 2,307 units (an 87.9-percent increase), the Juke an extra 1,081 units (a 45.8-percent increase), the Altima an extra 1,051 units (a 4.9-percent increase) and the Maxima an additional 983 units (a 32.9-percent increase). Honda, meanwhile, was hurt by falling sales of the Accord (down 13.9 percent) and Pilot (down 7.6 percent), and stagnant sales of the Civic.
Honda, however, should take pride in the fact that it's luxury division, Acura, outsold Infiniti, Nissan's luxury division, last month - 10,823 units sold to 8,998. That margin of victory was large enough to keep the parent company of American Honda ahead of Nissan North America for the month of January.
