Next-gen Nissan Leaf will look more mainstream, have more range

The next-generation Nissan Leaf battery-electric vehicle will look better and go farther on a single charge, company executives tell Automotive News. How much better and how much farther remains to be seen, as does the timing on when the new version will be available to the public. Nissan executive Andy Palmer, speaking recently at the Beijing Motor Show, implied that an electric vehicle would need to have a 185-mile single-charge range to be competitive with hydrogen fuel-cell vehicles, once those arrive in larger numbers. While Nissan boosted its single-charge range by about 15 percent for the 2014 model-year Leaf, the automaker would need to double it to reach that competitive threshold. This seems unlikely for the next-gen model, but we can start making our guesses as to how many more miles Nissan will put into the pack. Regardless, the next-generation Leaf, which may come out around 2017, will at least look a bit more mainstream while it reaches for more range, Automotive News says, citing Nissan global design chief Mamoru Aoki. Indeed, the car, which will keep its hatchback layout, will likely look less angular, said Aoki, who complimented Tesla for the way it styled its Model S luxury electric sedan. Nissan's Infiniti arm could also debut its delayed luxury electric vehicle in 2017, complete with the improved battery pack. Angular looks and all, Nissan continues to increase sales in the US. Leaf sales through April were up 33 percent from 2013, to 7,272 units after more than doubling sales last year to 22,610 vehicles.

Nissan gives us the business on the art of clay modeling

The team from The Dashboard recently stopped by the Nissan Technical Center in Japan for a look at what exactly goes into creating a full-scale clay model. While automakers have been using clay bucks for decades, designers and engineers are now combining computer renderings and hand-sculpted clay models to determine how a new vehicle will look in our world. Engineers use specially formulated clay kept warm in an oven to bring the body panels to life. They then coat the clay in a thin plastic film to add body color for the final look.
By the time everything is said and done, workers may have hundreds of hours in the model's creation. So, what happens when the company no longer needs the buck? They get scrapped. Someone comes in and dismantles the whole creation. We presume that action is set to the wailing tears of everyone who had a hand in building the model. Check out the video below for a closer look.

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.
