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.

Recharge Wrap-up: Nissan Leaf top environmental performer, 50,000th Renault Zoe

Renault has produced its 50,000th Zoe electric car. A Frenchwoman named Sylvie took ownership of the milestone vehicle at the Flins plant where it rolled of the line. She says her children helped convince her to buy the all-electric vehicle, which Sylvie intends to use as a daily driver. The Renault Zoe is Europe's best selling EV since its launch in 2013. Renault reports a 98-percent satisfaction rate with the Zoe. Read more in the press release from Renault. Toyota will use a biosynthetic rubber called biohydrin in its engine and drive system hoses beginning in May 2016. Jointly developed by Toyota, biohydrin is a plant-based rubber with a 20-percent reduction in material lifecycle carbon emissions compared to petroleum-based rubber. Toyota plans to use the compound in even more components in the future, including brake and fuel line hoses. Read more from Toyota. So far in 2016, only 27.5 percent of hybrids and EVs are traded in for another electrified vehicle, according to Edmunds. That's down from 38.5 percent in 2015. 33.8 percent of electrified vehicles are traded in for SUVs. Despite the trend of EV and hybrid owners switching back to traditionally powered vehicles, average fuel economy isn't suffering. "This is an economics trend, since today's low cost of gas no longer makes it worth paying the price premium of hybrids and EVs," says Edmunds Director of Industry Analysis Jessica Caldwell. "And there are so many fuel-efficient vehicles on the market today that environmental concerns weigh less than they might have in years past. When you're buying a vehicle that can get over 30 mpg, you can still say you're doing your part to help the environment." Read more from Edmunds. Environmentally, electrified vehicles outperform their conventional combustion counterparts throughout their lifecycle. A study from the Automotive Science Group (ASG) finds that while production of advanced powertrains comes with a greater financial burden, most vehicles make up for it through efficiencies during their use phase. The ASG lists the 2016 Nissan Leaf as its best performer, with 47 percent fewer greenhouse gas emissions than the best-performing conventionally powered car, the Honda Fit. Rounding out the ASG's top five environmental performers are the Ford Focus Electric, Chevrolet Volt, Toyota Prius Two Eco, and Hyundai Sonata Plug-In Hybrid.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum
