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.

Watch Ken Block play traffic cop in ’Top Gear’ teaser

BBC is teasing a new series of 'Top Gear' starring the rally racer and Hoonigans honcho Ken Block and promising that series 25 is "coming soon." Block plays a police officer (with a Los Angeles Police Department badge, no less) in an off-road 4x4 vehicle in the 30-second clip, jumping off obstacles and tearing through dirt in an industrial area near snow-capped mountains. He gives chase to show hosts Matt LeBlanc, in a yellow Ford Mustang, Rory Reid and Chris Harris, who steers a McLaren 570S. It looks like they're having more fun that the rest of us. LeBlanc has said the next season of episodes will aim to attract a younger, more diverse audience with more comedy. Series 25 is expected to launch in spring, perhaps after the wrap-up of the second season of 'The Grand Tour.'Related Video: Celebrities TV/Movies Ford McLaren Off-Road Vehicles Performance Top Gear Ken Block

Autoblog Video: Looking back on the 1965 Shelby GT350

The first Shelby GT350 Mustang came out a year after the first Ford Mustang, a collaboration between the carmaker and Carroll Shelby bent on making the Mustang a race winner. Perhaps even better than the car is Shelby's story behind its creation, when Ford chairman Lee Iaccoca gave him the "impossible job" of turning "a secretary's car... into a sports car." Shelby and his cohorts got that job done immediately, taking three SCCA B-Class national championships. The latest Ford Shelby GT350 is coming a year after the latest Mustang's debut, and it's certainly got the specs on paper to look like a track monster, especially in GT350R form. This year the Rolex Monterey Motorsports Reunion celebrated the 50th anniversary of the Shelby GT350 Mustang, and the Pebble Beach Concours D'Elegance featured the car in a special category. We took the opportunity to look at what makes the old GT350 so special, and why the new one stays true to the legendary name. Check it out in the video above. Related Video:
