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.

GM already raising prices on 2014 Silverado and Sierra pickups

General Motors must be pretty pleased with sales of its two newest pickups, the GMC Sierra and Chevrolet Silverado, as it's announced price hikes for both models, as part of a planned price tweak.
Prices will be bumped by as much as $1,500, although weirdly, they'll be offset by as much as $1,500 in cash-back offers through the end of October. Fox Business reports that GM spokesman Jim Cain said of the price hike, "With the sell down of the '13 models nearly complete, this price adjustment was planned and is a normal part of business."
The move, as Fox is quick to point out, is an interesting one, as sales of the twin pickups struggled last month relative to the Ford F-Series, while both of GM's crosstown competitors have been aggressively undercutting Silverado and Sierra prices. The F-150 starts at $24,070 and the Ram 1500 comes in at $23,600, not counting any cash on the hood. A base Silverado, meanwhile, retails at $25,575.

2015 Ford F-150 shaves 700 pounds, adds 2.7-liter EcoBoost [w/video]

The Ford F-150 is one of the best selling vehicles on the planet. Considering that, one can imagine that when it comes time for a redesign, there are hardly any half measures. For its lucky thirteenth generation, Ford has gone all-in on the single most important vehicle in its portfolio, redesigning it from the ground up.
The big news is the F-150's new, lightweight, Atlas-inspired body. Ninety-three percent of that new body is made from a sort of aluminum alloy not unlike what the US military uses in its M2 Bradley fighting vehicles and Humvees, and it accounts for up to 70 percent of the F-150's 700-pound weight reduction. As a side benefit, the aluminum body should prove more resistant to dents and dings. Built Ford tough, indeed.
If you're wondering where the other 30 percent of that 700-pound weight loss went, 8.5 percent (60 pounds) came from the increased use of high-strength steel (up from 23 percent to 77 percent) in its ladder-box frame. Ford claims this steel is comparable to some of the heavy duty pickups used by its competitors, with a PSI rating of 70,000.
