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 could have bought a stake in Aston Martin as early as 2012

Aston Martin has a very interesting future ahead of it. While the British brand appeared to be struggling with aging tech for a while, fresh investment from Daimler may have shown a light toward the future with the brand getting engines and electronics from them. Also, former Renault-Nissan top exec Andy Palmer has jumped ship from the French/Japanese automaker to become CEO of the much smaller sports car company. Interestingly, though, new reports from unnamed Nissan sources have indicated that Palmer has been pushing to work with AM for years.
Three unnamed company insiders told Reuters that Palmer made attempts to convince Renault-Nissan CEO Carlos Ghosn in 2012 and 2013 to invest in Aston Martin, but his proposals were shot down both times for unspecified reasons, according to Automotive News. "We looked carefully at the proposal but we passed on it," said one of the sources.
You can easily see why Palmer was eying Aston Martin even back in 2012. It's no secret that the British sports car mavens were in need of extra funding, well before the Daimler investment. Building vehicles these days is only getting more expensive with stronger safety and emissions requirements. Just look at the brand's desperate hope to get a side-impact crash exemption to keep selling its models in the US as an example.

Nissan Qashai gets the Juke R treatment

It would appear that we're a little behind the times on this one, but a UK-based tuner of the Nissan GT-R is creating its own take on the lustworthy Juke-R starting with the Nissan Qashqai crossover. Severnvalley Motorsport claims to be the leading authority for tuning of the current GT-R in Europe. The outfit is now turning its attention to stuffing the drivetrain of a GT-R under the body of a Qashqai+2 - a seven-passenger compact crossover similar in size to our Nissan Rogue - resulting in the Qashqai-R.
The project started back in March when Severnvalley took delivery of a new Qashqai. After stripping the crossover down to its bare essentials and building a custom jig to support the body shell, it was then transferred onto an awaiting GT-R chassis. The crew aimed to keep Qashqai's appearance as stock as possible, but fender extensions and hood vents were required to accommodate the sports car underpinnings.
The white Qashqai-R seen above will be tuned to produce 900 horsepower, while a black version will get bumped up to 1,000 hp. And, looking at the build photos, we surmise that this project will take nothing less than a herculean feat of supercar determination before it's through.
