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.

70% of pickups could use aluminum by 2025

In the next decade, the auto industry will see an explosion in its use of aluminum to cut weight and increase fuel economy, according to a study from market analysts Ducker Worldwide cited by The Detroit News. We are already seeing the lightweight metal show up extensively in luxury models from Europe, but with the impending launch of aluminum-intensive 2015 Ford F-150 (pictured above), North America is using it even more, as well. The report predicts 70 percent of US pickups to have aluminum bodies by 2025.
It won't just be pickups that see the benefit, though. The average amount of aluminum in US vehicles is forecasted by the study to grow from an average of 350 pounds in 2013 to about 550 pounds by 2025. The most common parts to use it will be hoods, doors and - to some extent - roofs, as well.
The massive increase in pickups' aluminum content hardly seems surprising. The F-150 is predicted to use so much that it might cause a short-term shortage, according to one earlier report. At the same time General Motors is heavily rumored to be negotiating with suppliers for the next generation Chevrolet Silverado and GMC Sierra. Ram is the last holdout of the Big Three, but the study predicts that not to last.

Ford 1.0L takes third-straight International Engine of the Year award

Ford's 1.0-liter EcoBoost is proving to be The Little Engine That Could, and it continues to acquit itself well, finding favor as one of the best powerplants in the world. To confirm it yet again, the tiny mill just won the International Engine of the Year award for the third year in a row, likewise also nabbing the title in the Sub 1.0-liter category.
Packing 123 horsepower and 148 pound-feet of torque with overboost (125 lb-ft normally), the tiny engine combines impressive power in a size small enough to be a carry-on item for a commercial flight. US buyers only got a taste of the award winner in the 2014 Fiesta, while the 1.0 EcoBoost has been available throughout the Ford lineup in Europe for a few years now. American sales have reportedly been strong, however, and next up in the US, the mill will find its way into the 2015 Focus.
The panel of 82 jury members from 34 countries also named the Mercedes-AMG 2.0-liter turbo found in the A45, CLA45 and GLA45 AMG models with 355 hp and 332 lb-ft as the best New Engine for 2014. The electric powertrain from Tesla won Green Engine prize, and the 4.5-liter V8 from the Ferrari 458 Italia took home the honor of top Performance Engine yet again.
