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 Carlos Ghosn taps the brakes on autonomous car progress

"Self-driving cars remain a long way from commercial reality."
Nissan CEO Carlos Ghosn shocked the automotive industry last year when he announced that his company plans to offer consumers an autonomous car by 2020. The automaker even showed off its self-driving Leaf prototype as proof. He was bolder recently with the pronouncement that select markets could have them in 2018, if laws allowed. The boss' optimism appears to be waning, though, and he's now sounding a lot more conservative about the future. While driverless vehicles are still on the way, Ghosn is hedging his bets with a more gradual implementation of several systems.

Asking price for Paul Walker's GT-R from Fast & Furious nearly triples [w/video]

The German owner of the only Nissan Skyline GT-R to survive filming Fast & Furious (a.k.a., The Fast and the Furious 4) has put his car up for sale following the death of Paul Walker, Yahoo Autos reports. The original sale price was reportedly an already hefty 300,000 euros ($412,110), but it has since been raised to 1,000,000 euros ($1.37 million).
Despite many well-intentioned efforts, the Skyline GT-R was (and still is) illegal to import for street use in the US, so this R34-generation GT-R and seven others were shipped here without engines and classified as kit cars to sidestep federal law. Once here, the engines were installed, and seven street-legal GT-Rs proceeded to be destroyed during the filming of F&F. But one car, the "hero" car for sale here, was driven by Walker in non-violent scenes and thus is the only GT-R that survived filming.
Then, in July 2009, the federal government cracked down on importers of these cars, seizing almost 50 GT-Rs, including this one, telling owners to export them or risk having them destroyed. The hero GT-R was therefore exported, and its whereabouts have been unknown until recently, when the current German owner allowed it to be featured in a review (watch the German-language video below). You can see the online ad (also German) of the heavily modified GT-R here, where it sits proudly with its sky-high price tag.
