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.

Ford previews updated Police Interceptor Utility for Chicago debut

With more law enforcement agencies across the United States alone than we'd care to count (or ever encounter), selling police cars means big business for American automakers, with Ford, Chevy and Dodge competing to fill the motorpools of every police department, sheriff's office and government agency in the land. For its part, Ford offers the Taurus-based Police Interceptor sedan and the Explorer-based Police Interceptor Utility, and it's preparing to unveil a revised version of the latter at the upcoming Chicago Auto Show in the same city where it's built. Dearborn hasn't given us much to go on with this teaser, showing just a darkened front shot of the vehicle in question with its emergency lighting all aglow. But it's fairly clear that the Interceptor Utility has been given many of the same updates applied recently to the Explorer on which it's based. That starts with the revised sheet metal, but considering that the Interceptor Utility exclusively packs V6 power, the 2.3-liter EcoBoost four that was one of the biggest updates to the civilian Explorer isn't likely to carry over. Ford does, however, promise that the revised Police Interceptor Utility will be "even better" than the model it replaces" and pack "more high-tech features." Related Video:

Toyota hangs on to title of world's largest automaker for first half of 2013

General Motors and Ford can have all the success they please, but it doesn't seem like America's two largest manufacturers are going to topple Toyota in the first half of 2013. According to Reuters, Toyota moved 4.91 million vehicles in the first six months of 2013, representing a 1.1-percent drop from the same period in 2012.
GM is on the rise, though, with a four-percent increase in global sales, to 4.85 million. Volkswagen, still sitting in third, saw a 5.5-percent jump to 4.7 million vehicles in the first half of 2013.
If this pace continues for Toyota, it'll finish 2013 in the top sales spot for the second year in a row. The manufacturer fell to third, behind GM and VW, in 2011 after earthquakes and tsunamis ravaged its production capacity.
