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.

Next Ford F-150 delayed for aluminum body panel issues?

The timetable for next-generation Ford F-150 may be in trouble if a report from The Truth About Cars is true. The next F-150 is slated to make extensive use of weight-saving aluminum in its body, but the aluminum alloy provided by suppliers hasn't met Ford's requirements in the earliest phases of pre-production, according to the report.
The F-150 represents a huge portion of Ford's profits and is the best-selling truck in the US, even in the face of increased pressure from cross-town rivals General Motors and Ram. While the current truck is treading water against its competition, we'd be lying if we said the F-150 weren't growing quite long in the tooth.
If production of the next-generation of the Ford cash cow, said to be based on the Atlas Concept from the 2013 Detroit Auto Show (pictured above), is delayed, it could be bad for Ford. Production at Ford's Dearborn Truck Plant is already set to be delayed six to ten weeks, missing an internal on-sale deadline of Memorial Day.

Ford trademarking 'Mach 1,' possibly for Mustang

A legendary name might be accompanying the redesigned, 2015 Mustang when it finally makes its world debut - Mach 1. Stumbled upon by the team at Ford Authority, the Mach 1 title was found in a trademark filing with the US Patent and Trademark Office, and would revive a name last used on the fourth-generation, 2003 Mustang.
While the the 2003 vintage was well and good, the Mach 1 is really remembered for a three-year run from 1969 to 1971 - it's best to just forget the emissions-choked 1972 to 1978 Mach 1s - when power output ranged from a modest 250 horsepower with the two-barrel, 351-cubic-inch Windsor V8 to "375 hp" (actual output was rumored to be well north of 400 horsepower) with the righteous, 429-cubic-inch Super Cobra Jet V8.
What does the title hold for the sixth-generation Mustang? It's tough to say. The fanatics at Ford Authority seem to think Mach 1 could take the place of the Shelby GT500 at the top of the Mustang hierarchy, which sounds like a valid argument. At the same time, we could see the SVT Cobra moniker returning for the flagship model, and the Mach 1 doing battle with the Chevrolet Camaro Z/28 (unless the Boss 302 were to return). Confounding things is the historical precedent - the Mach 1 was responsible for the death of the Mustang GT in 1969, so it might make sense as a volume performance model.
