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 plan to supply US Mitsubishi dealers with family sedan stalls

Mitsubishi has quietly had some big success recently. The Japanese brand sold 77,643 vehicles in the US for all of 2014, a 24.8 percent jump over 2013. While still relatively small overall (Ford sold 74,355 F-Series trucks just in December, for example), it shows definite growth for the sometimes forgotten automaker. Unfortunately, the latest news might not help the company's future expansion. The proposed partnership of Mitsubishi and the Renault-Nissan Alliance on at least one midsize sedan for the US market is off the table, according to Automotive News. The company informed sellers that the collaboration had fallen through during a National Automobile Dealers Association meeting. "I told them that the plan has stalled," said Don Swearingen, executive vice president of Mitsubishi Motors North America, to Automotive News. "And I said that's really all I can tell you at this time." Under the original partnership, Mitsubishi was supposed to get a D-segment sedan that would have been built at the Renault-Samsung factory in Busan, South Korea. The automakers were also negotiating for Mitsu to get a C-segment four-door as a global model and developing an electric kei car for Japan together, due in 2016. While the sedan is gone, Mitsubishi isn't completely bereft of improved products in the pipeline. The Mirage Sedan is being launched in the US, and the Outlander is supposed to get a redesign for the 2016 model year. According to Automotive News, the Outlander Sport and Lancer are also due for refreshes in 2016, and a new Mirage is on the way.

Recharge Wrap-up: Formula E's other events, continued record EV sales

Formula E wants fans to know that it is more than just a race. During each ePrix weekend, the electric race series hosts a variety of events. For each race, Formula E sets up an eVillage where fans can meet drivers and get autographs, learn about electric vehicles, spectate Formula E's School Series races, enjoy live music and dance performances, play games, eat food and take part in numerous other activities that don't make their way into the television broadcast. Or course, though, the race is always the main event. See more in the video above. Electric vehicles enjoyed a fourth straight month of record sales in February. Despite low oil prices, customers bought an estimated 7,881 EVs last month, up 13 percent from a year before. 52 percent of those sales were battery electric vehicles, while the rest were plug-in hybrids. BMW i3 sales dropped 77 percent over a year ago, selling 248 cars. The Tesla Model S and Chevrolet Volt sold the most, while the Ford Fusion Energi outsold the Nissan Leaf for the first time. The Audi A3 E-Tron sold 248 units (same as the BMW i3) despite low inventory. Read more at Inside EVs. Renault more than doubled its EV sales in January compared to a year before. Sales were up 104 percent, at 1,886 units (1,977 if you include the Twizy). This January marked higher EV sales for Renault than the three previous years.
