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: Nissan Murano Hybrid in China, FCA hearts E15

Fiat Chrysler Automobiles (FCA) has approved the use of E15 in its 2016 model year vehicles. The Renewable Fuels Association is pleased with the automaker's choice to cover the higher ethanol blend in its warranty statements, describing it as a positive signal for the future growth of E15. "FCA's decision to join GM and Ford provides clear evidence that the tide on E15 has turned," says RFA President and CEO Bob Dinneen. "The automaker's decision not to embrace E15 had been a major point of concern and tension for the last three years." Read more from the RFA. Skoda's head of purchasing, Dieter Seemann, discusses sourcing EV components in a new interview. He says the biggest challenge is seeking out future suppliers for electric motor and connected vehicle components. "We have to really understand what happens in this business to identify the right partners to have in five to eight years from now," says Seemann. "Many of these are suppliers completely new to us." He says Skoda purchases 50 to 55 percent of its parts directly, while chassis and powertrain parts are shared among other Volkswagen Group brands. Read the full interview at Automotive News Europe. Nissan is helping the European Commission develop a pedestrian alert system for electric vehicles. Called Electric Vehicle Alert for Detection and Emergency Response (eVADER), the project aims to develop technology that provides audible cues to alert pedestrians to oncoming vehicles without contributing to noise pollution. Nissan created a system for the Leaf that uses a camera to recognize pedestrians and cyclists and direct a sound in their direction. This work will help the EU shape its laws moving forward.

Nissan GT-R takes a bloody whack at supercar rivals in fake ads

A big part of what makes a supercar super is how it makes you feel, but the performance stats and bragging rights are undeniably a big part of the equation as well. Which means you can't ignore the fact that, even with its price ever escalating, the Nissan GT-R makes minced meat out of European exotics costing twice or three times as much.
That's the inspiration for this trio of fake ads from photographer Tim Kent. In this mock campaign, Kent has depicted the GT-R as a butcher's knife and the European exotics as pieces of slaughtered meat. Ferrari is symbolized by a package of horse meat, Porsche by a pack of sausages and Lamborghini as a pair of, um... "prairie oysters".
Of course the ads are never going to run anywhere, and if you're squeamish (or vegetarian) we wouldn't suggest looking at them in close proximity to your lunch. But we have to admit they're creative, and effective.
