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.

How Chevy Silverado, GMC Sierra will take on the Ford F-150 profit machine

FORT WAYNE, Ind. — When General Motors engineers were developing the 2019 Chevrolet Silverado and GMC Sierra pickup trucks, some of them joined public tours of Ford's Dearborn, Mich., factory to watch aluminum-bodied F-Series trucks go down the assembly line. The redesign of the Ford F-Series trucks, launched in 2014, set a new standard for fuel economy and lightweight vehicle construction. But armed with stopwatches and trained eyes, the GM engineers believed they saw problems. "They had a real hard time getting those doors to fit," Tim Herrick, the executive chief engineer for GM truck programs, told Reuters. His team did more intelligence gathering. They bought and tore apart Ford F-Series doors sold as repair parts. Their conclusion: GM could cut weight in its trucks for a lower cost using doors made of a combination of aluminum and high-strength steel that could be thinner than standard steel, shaving off kilograms in the process. These pounds-and-pennies decisions will have major implications in the highest-stakes game going in Detroit: dominance in the world's most profitable vehicle market, the gasoline-fueled large pickup segment. What's more, GM is banking on strong sales of overhauled 2019 Silverados and GMC Sierras to fund its push into automated and electric vehicles — a business many investors see as the auto industry's long-term future. The risks are high given the hits automakers have taken from U.S. President Donald Trump's trade policies. Rising aluminum prices spurred by Trump's tariffs are driving up costs on the Ford's F-Series, while rising steel and aluminum prices likewise drag on GM results. GM also has a significant risk should the United States, Mexico and Canada fail to agree on a new NAFTA trade deal, given GM trucks built at its Silao, Mexico, factory could face a 25 percent tariff if NAFTA collapses. Major profit per truck Interviews with GM executives and a tour at its factory here in northwest Indiana provide a detailed look inside GM's plan for the most important vehicles in its global lineup. These big pickups are everything Tesla's Model 3 or Chevy's Bolt electric car is not. The mostly steel body is bolted to the truck's steel frame, rather than the one-piece body and frame electric vehicles. The majority of trucks will have a V-8 gasoline engine powering the rear wheels — like the classic GM cars of the 1950s. Some Silverados will have new four-cylinder engines, but there is no electric or hybrid offering as of now.

Ford to add Android Auto and CarPlay to 2016 SYNC 3 cars via update

Ford is updating a large number of 2016 model year cars equipped with SYNC 3 infotainment software, adding Android Auto and CarPlay to the vehicles with a free, over-the-air update via Wi-Fi, or using either USB or going through their dealer. The upgrade will be available for around 800,000 vehicles in total, giving a huge number of Ford car owners the chance to get big infotainment improvements without having to buy a newer model car. The OTA update option is also a big step for Ford – it's the company's first for software ever, and it's one of the major reasons that Ford recently hired around 400 new mobile smartphone engineers, the company tells me. For CarPlay, users will still also need to upgrade their vehicle's USB hub to make this work (which will also incur a dealer visit and a cost), but for those on Android, all that's required is a simple software installation. The USB install method is also faster, but the Wi-Fi update option is the start of the company's efforts to really increase its OTA update program, which will be used for security improvements as well as infotainment bumps. Even with a dealer visit and hardware upgrade for CarPlay, this sounds like a worthwhile thing for 2016 vehicle owners to do. CarPlay and Android Auto are huge upgrades vs. most in-car software, offering navigation and entertainment options that follow you from your phone to your car. Retroactively offering this kind of thing to car owners is a definite change in tone for carmakers, since they typically use these kinds of things as incentives to get people interested in vehicle model updates. But as data becomes increasingly important to automakers as a business, it makes sense to encourage greater in-car use of devices.Written by Darrell Etherington for TechCrunchRelated Video: Auto News Ford Lincoln Technology Infotainment android
