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.

Ford announces first non-pursuit-rated police car ever

Ford announced its first non-pursuit-rated Police Interceptor ever, based on the Taurus, which employs the smaller 2.0-liter EcoBoost four-cylinder engine in place of similar pursuit-rated Police Interceptors powered by naturally aspirated 3.5-liter and 3.7-liter V6s and the top-spec 3.5-liter EcoBoost V6. Officially called the Special Service Police sedan, the car was commissioned at the request of law-enforcement agencies that desire a more fuel-efficient vehicle for detectives, administrators and campus police, who don't necessarily need pursuit-rated vehicles.
The 2.0-liter EcoBoost engine produces 240 horsepower and 270 pound-feet of torque, but more importantly, it allows the SSP sedan to achieve somewhere in the neighborhood of 22 miles per gallon city and 32 mpg highway, which are the civilian 2.0-liter Taurus' official EPA ratings. Ford estimates that the SSP sedan will get 20 mpg city, 30 mpg highway and 23 mpg combined, with the help of Active Grille Shutters that open to allow more cooling air through to the radiator, or close to optimize aerodynamics and fuel economy. Those numbers compare favorably to the discontinued Crown Victoria-based Interceptor's 14 mpg city and 21 mpg highway and the newer Taurus-based cars equipped with V6s, the most fuel efficient of which gets 18 mpg city and 26 mpg highway.
If it was driven 90,000 miles over the course of three years, a 2.0-liter SSP sedan would save law enforcement agencies $5,042.92 versus the Crown Vic, Ford estimates. The EPA is expected to post official fuel-economy numbers for the SSP sedan in December. Until then, read the press release below for more information.

GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.
