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.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

Ford Shelby GT350R sets 7:32.19 Nurburgring lap time

It was over a year ago that the Chevy Camaro Z/28 clocked a Nurburgring lap time of 7 minutes and 37.47 seconds, propelling itself up the leader boards as the fastest American muscle car to lap the infamous Nordschleife. But now word has it that another piece of Detroit iron has clocked an even faster time. According to Evo, the new Ford Shelby GT350R Mustang has lapped the Green Hell in a blitzkrieg 7:32.19. That's more than five seconds faster than the Z/28, and propels the GT350R into proper supercar territory: incrementally quicker than the Ferrari 458 Italia and in league with lap times posted by the Nissan GT-R (though not the fastest Godzilla has clocked over the years). With output quoted at "more than 500 horsepower and more than 400 lb-ft of torque," and no 0-60, quarter-mile or top end figures revealed to date, this marks the first genuine measure of performance we've seen for the track-focused pony car - though the numbers have yet to be officially confirmed. The GT350R packs a 5.2-liter V8 unburdened by 130 pounds of excess weight – helped along by carbon-fiber wheels coated in Michelin Pilot Sport Cup 2 rubber. Related Video:
