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 recalling 2012-14 Frontier pickups over fire risk

Nissan is recalling its Frontier pickup over fire concerns, according to a National Highway Traffic Safety Administration bulletin. A total of 13,535 vehicles are being recalled, all from the 2012 to 2014 model years, built between November 28, 2012 and December 27, 2013.
The NHTSA report states that "in the affected vehicles, a circuit breaker may have been installed incorrectly causing the main wire harness connected to the circuit breaker to face outward, potentially contacting a metal bolt located on the A-pillar." If this happens, it's possible that "the bolt may wear though the wire harness covering, resulting in an electrical short," NHTSA states. In the event of an electric short, a fire may occur.
The official recall will begin in March, where Nissan dealers will inspect the circuit breaker for the correct orientation, and if necessary, repair the vehicles, free of charge. Scroll down for the full NHTSA bulletin.

Renault and the Eco2charge consortium are working to bring better EV charging to France. They are providing research and development aimed at turning simple charging stations into "fully fledged energy ecosystems" through a smart grid. This grid would coordinate charging, consumption and energy storage in a way that increases efficiency and decreases cost. Read more in the press release below. The Renault-Nissan Alliance could source EV batteries from suppliers other than Nissan, according to CEO Carlos Ghosn. This news comes after recent questions of whether or not Nissan would scale back battery production in the US and UK. Ghosn says, "At the moment, we continue to produce our own batteries and we are open to outside sourcing, period." He also denies any plans to shutter Nissan's battery production facility in Tennessee. One source of batteries the alliance will look to is Korea's LG Chem. Read more at Automotive News Europe. The first-ever Green Fleet Car and Truck of the Year Awards will be presented at the Los Angeles Auto Show. The presentation on November 20 will be part of the LA show's Connected Car Expo.
