Nissan 370Z Nismo Roadster Concept looks ready to roll

Honestly, we're kind of surprised this hasn't happened already. The Nissan 370Z Nismo is a pretty cool little package, better than ever in its 2015 model year iteration. So why not apply that same, go-faster, look-cooler formula to the topless Z Roadster? That's exactly what Nissan's done here in Chicago, showing the 370Z Nismo Roadster you see here. Aesthetically, it's pretty much the same as the coupe – except, of course, for the folding cloth roof that neatly stows behind the front seats. It's mechanically the same, too, with Nissan's 3.7-liter naturally aspirated V6 underhood, making 350 horsepower. Oddly, the concept car uses the company's seven-speed automatic transmission, but as Nissan explains, the majority of Z Roadster buyers spec their cars with the slushbox. "While it is only a design study at this point, we think the 370Z Nismo Roaster Concept would be a tremendous addition to the long and distinguished history of Z sports cars," Pierre Loing, Nissan's vice president of product planning in North America, said in a press release. It sure looks production-ready to us. Nissan 370Z NISMO Roadster Concept makes world debut at 2015 Chicago Auto Show - Combines legendary NISMO performance, style and technology with Nissan 370Z Roadster open-air motoring excitement - One-off design study created to gauge market interest in an ultimate factory Z® Roadster - Offers unique engine, suspension, exterior and interior features versus standard Nissan 370Z Roadster models – including 350-horsepower 3.7-liter V6 and NISMO-tuned suspension - Would join current Nissan 370Z NISMO coupe model, expanding NISMO lineup to five models As the heart and soul of Nissan performance for both the track and on the street, NISMO continues to set the standard for straight-from-the-factory enthusiast vehicles. The lineup of NISMO production models for 2015 includes the GT-R NISMO, 370Z NISMO, JUKE NISMO and JUKE NISMO RS. Yet as the popularity of NISMO models continues to grow – the 2015 GT-R NISMO is sold out, the 370Z NISMO accounts for 20 percent of total sales and JUKE NISMO models for about 15 percent – one group of performance enthusiast remains left out: Open-air sports car lovers. Enter the Nissan 370Z NISMO Roadster Concept, which makes its world debut at the 2015 Chicago Auto Show. The custom vehicle combines the long list of 370Z NISMO Coupe performance equipment with a modified 370Z Roadster body and interior.

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 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.
