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.

Recharge Wrap-up: Tesla Model X 0-100 video, Nissan-Renault record EV sales

A video shows that a Tesla Model X can accelerate from 0-100 mph faster than a Model S P85D. DragTimes tested a Founders Edition Tesla Model X P90D with Ludicrous Mode, and found that it did 0-60 mph in 3.178 seconds, which is faster than Tesla's stated 3.2 seconds. The 0-100 mph happened in just 7.98 seconds, which is faster than the 8.3 seconds DragTimes clocked in Model S P85D using Insane Mode. Even more impressive is that the Model X used is a seven-seater with all the boxes ticked, which means that it's lugging a lot of extra weight on the drag strip. DragTimes says it intends to do more tests with other configurations of Tesla models – perhaps we'll get to see how two vehicles with Ludicrous Mode compare. See the video above, and read more at Teslarati. Nissan and Renault saw record sales of electric vehicles in 2015. The two automakers sold 84,754 battery-powered vehicles last year, a rise of 2.5 percent. Nissan Leaf and e-NV200 sales dropped by almost 10 percent, but Leaf sales are expected to improve with the next generation. The Alliance's EV sales, though, were boosted by Renault selling 45 percent more EVs in 2015. Government incentives in France are partially responsible for Renault's success. Since they began selling them, Renault and Nissan have sold 302,000 EVs worldwide by the end of 2015. Read more at Bloomberg Business. A study finds that E20 provides higher peak load capability and thermal efficiency than gasoline in reactivity-controlled compression ignition (RCCI) combustion. The dual-fuel combustion technique uses in-cylinder blending to optimize combustion. The study used E20 ethanol blend or gasoline blended with highway diesel or B20 biodiesel blend and compared the results. In addition to the load capacity and thermal efficiency benefits, E20 also produced fewer hydrocarbon emissions. Read more at Green Car Congress.

Nissan recalling 151,000 CUVs over ABS issues

Nissan will be recalling over 151,000 vehicles due to issues with the anti-lock braking systems. On rough roads, light braking in the Nissan Pathfinder, Infiniti JX35 and QX60 could trigger a problem in the brake pressure output software that might lead to longer stopping distances than expected relative to the brake inputs. Needless to say, unpredictable stopping distances on rough roads is not a desirable trait in a three-row, family friendly CUV.
The recall covers all 2013 and 2014 Nissan Pathfinders built between April 18, 2012 and September 20, 2013, some 100,682 vehicles. Another 52,629 2013 to 2014 Infiniti JX35/QX60s built between September 15, 2011 and September 20, 2013 are also part of the notice.
Nissan will request that owners of affected vehicles report to dealers for a free software update to address the problem. Scroll down for the official notification from the National Highway Traffic Safety Administration.
