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 using robot drivers to test durability [w/video]

In testing the durability of its upcoming fullsize Transit vans, Ford has begun using autonomous robotic technology to pilot vehicles through the punishing courses of its Michigan Proving Grounds test facility. The autonomous tech allows Ford to run more durability tests in a single day than it could with human drivers, as well as create even more challenging tests that wouldn't be safe to run with a human behind the wheel.
The technology being used was developed by Utah-based Autonomous Solutions, and isn't quite like the totally autonomous vehicles being developed by companies like Google and Audi for use out in the real world. Rather, Ford's autonomous test vehicles follow a pre-programmed course and their position is tracked via GPS and cameras that are being monitored from a central control room. Though the route is predetermined, the robotic control module operates the steering, acceleration and braking to keep the vehicle on course as it drives over broken concrete, cobblestones, metal grates, rough gravel, mud pits and oversize speed bumps.
Scroll down to watch the robotic drivers in action, though be warned that you're headed for disappointment if you expect to see a Centurion behind the wheel (nerd alert!). The setup looks more like a Mythbusters experiment than a scene from Battlestar Galactica.
