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.

Expert: 54.5 mpg CAFE standard can be reached without many plug-ins

Johnson Controls executive Brian Kesseler isn't likely to get any holiday presents this year from Nissan chief Carlos Ghosn or Tesla Motors head Elon Musk, but lots of other folks might be happy with what he has to say about automakers' efforts to reach stricter fleetwide fuel-economy standards. Speaking at the Automotive News World Congress, Kesseler said automakers wouldn't need to sell an extensive number of plug-in vehicles in order to meet the 54.5 mile per gallon Corporate Average Fuel Economy (CAFE) standard the US government set in 2012 for 2025 model-year vehicles. In fact, he said, components such as stop-start engine technology, turbochargers and direct injection may actually do the trick. Already, things like smaller engine sizes and lighter cars are already playing major roles in spurring fuel-efficiency gains. Of course, Johnson Controls sells batteries specially built for stop-start systems, so Kesseler does have a bit of skin in this game. The 54.5-mpg CAFE standard equates to about a 40-mpg "real world" fuel-efficiency level. To put that into perspective, the Environmental Protection Agency (EPA) said in a report late last year that model-year 2013 average fuel economy was an even 24 mpg. That was up from 23.6 mpg for the 2012 model year and 22.4 mpg for 2011.

Here's why automakers roll out those Texas-themed pickup trucks

Every year, automakers with a full-size truck link make a big show of the Texas State Fair, usually involving a reveal of a new model. Sometimes they show a whole new truck, and other times a special edition centered on the Lone Star state. While some people might write this off as a quirk of the industry, others might be wondering, "What's the big deal with Texas?" As it turns out, part of the big deal with Texas is big truck sales. According to Dave Sullivan, product analysis manager at AutoPacific, Texas buys more trucks than any other state in the country. It's not a small margin either. Edmunds.com, one in five trucks sold in the US are sold in Texas. The state also accounts for 15 percent of the country's large truck sales, which is more than twice that of California, the second largest truck market in America. Even when you break down sales only in Texas, trucks are a huge piece of the pie - Sullivan says that a quarter of new vehicle sales in Texas are trucks. One in five trucks sold in the US are sold in Texas. But it's not just sales that make truck builders give attention to Texas. As Sullivan explained, "Pickups are life in Texas." Both he and Hugh Milne, marketing and advertising manager for the Chevy Silverado line, said that trucks are key fixtures in Texas society, as both work trucks and luxury vehicles (or Texas Cadillacs as Milne called them). Milne said Texas is so important in the truck market that if you want to be successful in the rest of the country, "you've got to be successful in Texas." As for the State Fair, it has become a prime location for reveals in part because of the importance of the Texas market and because of how big the fair is. Milne also revealed that the State Fair also hosts its own auto show, so it's an ideal venue for a vehicle introduction. So there you have it. Why do truck builders obsess over Texas? It's because Texas obsesses over trucks. When you have one market that loves your product that much, you give it the attention it deserves.
