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.

This new Renault would make a great Nissan Maxima wagon

A new Renault station wagon wouldn't ordinarily show up on our radar. But this one gets us thinking. It's the new Talisman Estate, and we can't help but wonder if it wouldn't make a good addition to Nissan's North American lineup. If you recognize the name, you may recall that Renault launched the Talisman sedan on the other side of the pond last summer. At the time, we noticed some striking similarities to the Maxima sedan we get here, though Nissan told us the two were unrelated. But that wouldn't necessarily stop the wagon from sporting a different badge on the nose and making the transatlantic journey to American showrooms. The long-roofed version of the Talisman measures 191 inches long making it only a little longer than the BMW 3 Series Sports Wagon we get here, while riding on the same 110-inch wheelbase. But where the Bimmer offers up to 53 cubic feet of cargo space, the Renault can fit nearly 60. It also boasts electronic dampers and four-wheel steering to keep it light on its toes, and offers a selection of four-cylinder gasoline and diesel engines ranging from 110 horsepower up to 200.

Nissan IDX production model to get sharper, less retro styling

The Nissan IDx seems like the type of concept that auto enthusiasts wish they could be driving. With a compact size, style inspired by the classic Datsun 510 and a rear-wheel-drive powertrain, it certainly ticks many of the boxes that people want. Unfortunately, the car seems to be miles away from actually getting a green light for production, but rumors about the retro coupe's future keep cropping up.
The last we heard about the IDx, the biggest complication with the coupe was that it was a tough project to make profitable. Nissan didn't have a cheap enough rear-wheel drive platform to make the affordable coupe work. The latest rumors point to a potential solution to this problem. According to Motoring from Australia speaking to an insider close to Nissan, the new plan is to tweak the styling to be less retro and adapt the car to work on the platform for the forthcoming, next-generation Z car.
The new look reportedly cribs from the Nissan Sport Sedan Concept from the 2014 Detroit Motor Show, including its floating roof design and sharper edges around the fenders. In terms of power, the source tells Motoring, the IDx could use a naturally aspirated 2.0-liter four-cylinder engine with around 180 horsepower on tap. That might not sound like too much, but remember the Z car itself is rumored to get smaller and lighter when it's new generation hits the stage. If the weight is low enough, potentially using it for the IDx might just work.
