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.

Shelby GT500 and Roush Stage 3 go head to head at the drag strip

The Ford Mustang is a brilliantly affordable source of horsepower, with a base 300-plus-horsepower version available for well under $30,000. Jumping up to about $35,000 will get you a solid 420 horsepower from a high-revving V8, while those with some extra disposable income can get a pair of 600-plus-horsepower monsters. Both the Roush Stage 3 with its Phase 3 package and Ford's factory Shelby GT500 even crest the 650-horsepower mark, with 675 and 662 ponies, respectively.
Naturally, someone needed to find out which of these hi-po Mustangs was the quickest. And while this video is quite obviously a dealership commercial, at least there's some solid drag racing between two of the most powerful performance machines available for under $100,000.
With two NHRA drag racers at the wheel, the Stage 3 and GT500 go head to head for three races. Scroll down below to see the results in the full video.

More evidence GT500-replacement will be named GT350

During the recent unveiling of the 2015 Ford Mustang, we saw the car in both V6 and GT form, but we'll have to wait a little bit longer to see the successor to the Shelby GT500. In the meantime, though, it looks like SVTPerformance.com has confirmed reports that this high-performance model will bring the Shelby GT350 name back to Ford.
According to the forum post, a user found the Shelby GT350 name on a Ford promo website listing its 2015 lineup. The Shelby GT350 name was first used on a Mustang back in 1965, and most recently it has been a model created for customers as a post-title purchase by Shelby American. As for that car, Shelby confirmed earlier in the year that its GT350 would be phased out at the end of this month.
The million-dollar question for Mustang and Shelby enthusiasts is when we'll see next factory Shelby GT350. Last we heard it was planned for a debut at the New York Auto Show. We've included our previous spy shots of this hi-po, sixth-gen Mustang, and we've also captured it on spy video showing off its exhaust note.
