Nissan tests 'self-cleaning' paint on Leaf models in Europe

Once upon a time, self-cleaning ovens were all the rage. Now, Nissan thinks the concept may apply to its vehicles. And the Japanese vehicle maker is testing it out on some of its Leaf battery-electric vehicles Europe, no less. Nissan says its trying out what's called a "superhydrophobic and oleophobic" paint on Leaf battery-electric vehicles for testing and demonstration purposes. The paint, produced by UltraTech International Inc., is designed to repel splats of liquid such as oil or standing water away from the car's surface. The paint, called Ultra-Ever Dry, does this by creating what Nissan says is a layer of air around the vehicle surface. We imagine there's a detailed chemical explanation for this phenomenon that would better explain this process, but that's the best way we can explain it. Right now, Nissan is pitching the product testing as a way to further the Leaf's reputation as what the automaker calls "the world's cleanest car." That said, the paint hasn't been tested in North America, and no plans have been made to add the feature as either a standard or optional goodie for the battery-electric vehicle. Still, go ahead and check out Nissan's press release on the magic paint below. Nissan Creates "World's Cleanest Car" – a Zero Emissions Nissan LEAF with Self-Cleaning Nano-Paint Technology For LEAF owners who never qualify for gas stations' "Free Car Wash with Purchase" offers, this technical study might be the perfect solution July 09, 2014 10:00 AM Eastern Daylight Time NASHVILLE, Tenn.--(BUSINESS WIRE)--What do you get when you combine the world's best-selling zero emission vehicle with innovative paint technology that repels mud, rain and everyday dirt? Answer: A very special Nissan LEAF electric vehicle that might just be the "world's cleanest car." "No matter what the road throws at this LEAF, its Ultra-Ever Dry® exterior coating will throw right back" Created to demonstrate its potential use in future production vehicles, this Nissan LEAF's exterior was treated with a specially engineered superhydrophobic and oleophobic paint that is designed to repel water and oils. The "self-cleaning" paint, called Ultra-Ever Dry®, creates a protective layer of air between the paint and environment, effectively stopping standing water and road spray from creating dirty marks on the LEAF's surface. Nissan is one of the first carmakers to apply this technology to a vehicle.

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.

2015 Nissan Murano could have been a lot more boring to look at

When it debuted at the 2014 New York Auto Show, the third-generation Nissan Murano wowed us more than just about any other car on hand (that's sort of why we handed it an Editors' Choice for the NYIAS). It's sharp, aggressive design was a dramatic departure from the smoother styling of the second-gen CUV, although it wasn't too polarizing. Most importantly, though, it was a vehicle with actual design presence - you want to see it from every angle, all of which draw your eye with something new.
Of course, settling on the design for a new vehicle is far from a straightforward process. While a design might take shape on a designer's drafting table, there are a huge number of steps it needs to get through before making it to an auto show stage or to your local dealer. According to Nissan engineer Chris Reed, those steps very nearly curtailed the Murano's design before the first die was even cast.
Reed has a full account of this sharp design's trials and tribulations in a must-read story from Ward's.
