Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

70% of pickups could use aluminum by 2025

In the next decade, the auto industry will see an explosion in its use of aluminum to cut weight and increase fuel economy, according to a study from market analysts Ducker Worldwide cited by The Detroit News. We are already seeing the lightweight metal show up extensively in luxury models from Europe, but with the impending launch of aluminum-intensive 2015 Ford F-150 (pictured above), North America is using it even more, as well. The report predicts 70 percent of US pickups to have aluminum bodies by 2025.
It won't just be pickups that see the benefit, though. The average amount of aluminum in US vehicles is forecasted by the study to grow from an average of 350 pounds in 2013 to about 550 pounds by 2025. The most common parts to use it will be hoods, doors and - to some extent - roofs, as well.
The massive increase in pickups' aluminum content hardly seems surprising. The F-150 is predicted to use so much that it might cause a short-term shortage, according to one earlier report. At the same time General Motors is heavily rumored to be negotiating with suppliers for the next generation Chevrolet Silverado and GMC Sierra. Ram is the last holdout of the Big Three, but the study predicts that not to last.

2014 Ford Fiesta 1.0L EcoBoost to hit 45 mpg for $16,445*

When Ford first announced its plan to put the 1.0-liter EcoBoost three-cylinder engine under the hood of the 2014 Fiesta, it promised hybrid-like fuel economy without a hybrid-like premium. We're still waiting for official specs on this engine, but thanks to the EPA's fueleconomy.gov website and Ford's retail site, we now know what customers can expect in terms of both fuel economy and price.
All along, Ford has said that it expects the 1.0-liter EcoBoost to get more than 40 miles per gallon on the highway, and now the EPA backs this up with official ratings of 32 mpg in the city and 45 mpg on the highway. These numbers are an increase of two mpg city and four mpg hwy compared to the current fuel-sipping Fiesta (the 1.6 SFE), and it also beats other three-cylinder cars for highway mileage like the 2014 Mitsubishi Mirage (44 mpg highway) and 2014 Smart Fortwo (38 mpg highway); the Fiesta 1.0 EcoBoost is lower than both three-pot rivals, though, in city fuel economy with the Mitsubishi getting 37 mpg city and the Smart rated at 34 mpg city. This model handily beats high-volume small cars like the Honda Fit, Toyota Yaris and Chevy Spark in both city and highway numbers.
As for pricing, the 1.0-liter EcoBoost is offered on both the sedan and hatchback as a $995 option called the SE Manual EcoBoost package, which is aptly named since it's only offered on SE trim-level Fiestas equipped with a manual transmission. Along with the engine, the package also comes with 15-inch steel wheels, regenerative brakes and a decklid spoiler on the sedan. This means the four-door Fiesta 1.0 EcoBoost will start at $16,445*, or $17,045* for the hatchback (*not including $795 for destination).
