Ford C-Max Solar Energi takes a recharging station wherever it goes

Companies ranging in size from small startups to major automakers have been experimenting with solar-powered charging stations for EVs and plug-in hybrids. And, of course, people have been powering vehicles with onboard solar panels for quite some time, too. Still, Ford's new C-Max Solar Energi Concept shows the promise of a truly practical implementation of solar on a production vehicle, and it may not be as far off in the future as we had thought.
As we reported a few days ago, the Solar concept makes use of a "concentrator lens" that focuses sunlight onto the Ford's roof-mounted solar panels. The special lens follows the rays of the sun to maximize the amount of charge being fed to the batteries of the car, taking about a day to fully charge the 21-mile, all-electric range of the C-Max Energi. Ford data suggests that combination might be enough to power 75 percent of all trips made by a statistically average driver. In turn, using the sun to power a vehicle could reduce yearly C02 emissions by up to four metric tons when compared with the driver of an average gasoline-powered sedan.
We've got live images of the C-Max Solar Energi Concept, jauntily tilted on its display to best present it's signature solar panels, straight from the CES floor.

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

Bill Ford op-ed argues we can't just build and sell more of the same cars

It's hardly a secret that the auto industry is undergoing an enormous, tectonic shift in the way it thinks, builds cars and does business. Between alternative forms of energy, a renewed focus on low curb weights and aerodynamic bodies, the advent of driverless and autonomous cars and the need to reduce the our impact on the environment, it's very likely that the car that's built 10 years down the line will be scarcely recognizable when parked next to the car from 10 years ago.
Few people are as able to explain the industry's many upcoming changes and challenges as clearly as William Clay Ford, Jr., better known as Bill Ford. The 57-year-old currently sits as the executive chairman of the company his great-grandfather, Henry Ford, founded over 110 years ago.
In an op-ed piece in The Wall Street Journal (subscription required), Ford explains that the role of automakers is, necessarily, going to change to suit the needs of the future world. That means changing the view of not just the automobile, but the automaker. As Ford explains it, automakers will "move from being just car and truck manufacturers to become personal-mobility companies."
