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.

F-150 just the start of Ford's aluminum plans

Not only have we been told that the 2015 Ford F-150 is tougher, more durable and up to 700 pounds lighter than the current truck, Ford COO Mark Fields said it's also "CAFE-positive." That means, for the first time in the history of corporate average fuel economy standards, the F-150 would be a positive contributor on Ford's CAFE balance sheet instead of being a vehicle it needs to counterbalance with frugal offerings.
Fields' comments made at the Detroit Auto Show were among quotes from other Ford execs that confirmed the carmaker will be using aluminum for more of its vehicles. CEO Alan Mulally said it would "proliferate across our lineup," with speculation being that we'll see it applied to crossover and sport utility models first, since they'll benefit the most. Even gaining the massive scale of using aluminum on the world's best selling vehicle for its first effort - on average, the company sells two times as many F-150s in a single day as Land Rover sells of its aluminum Range Rover in a month - Ford will be looking to further spread the cost of its five-year development investment in aluminum technology. And that should mean better handling and fuel economy for those of us who don't need to wear hardhats at the office.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises.
