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.

Motor Trend pits Subaru WRX vs. Ford Focus ST

The Ford Focus ST has enjoyed a relatively calm, if brief, reign in the world of hot hatches. With nothing else in the class (in the States, at least) but the aging Mazdaspeed3 and Subaru Impreza WRX and the slow-selling Volkswagen Golf R, the Blue Oval's 252-horsepower five door has been the go-to vehicle for those that don't need the high-octane lunacy (and expense) of the rally bred Subaru Impreza WRX STI and Mitsubishi Lancer Evolution X.
Now, though, as the new Subaru WRX (it's not an Impreza anymore, though, neither is it a hatchback...) starts to arrive at dealers, the Focus ST appears to be under threat for the first time. Naturally, Motor Trend is here to figure out which one is the best, with another one of its Head 2 Head videos. Host Jonny Lieberman puts both cars through their paces, going above and beyond, quite literally, at the very end of the video.
