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.

2018 Ford Expedition spied looking stylish

The Ford Expedition and Lincoln Navigator got a cool reception for their 2015 warmed-over redesign. But with big, high-riding vehicles once again in vogue, Ford is pushing ahead with a ground-up redesign of its biggest SUVs. Based on these spy shots, the Expedition will continue to serve as the Navigator's more affordable twin. Yes, that's a bold prediction, considering we still haven't spotted Lincoln testing the new Navigator, but study the greenhouses on this Expedition prototype and the Navigator Concept from New York – from the arrow-straight belt line to the extra-long rear window to the aggressively raked windshield, this Expedition's overall profile is broadly similar to what Lincoln previewed earlier this year. While our spies claim the new Expedition will look to the F-150 for design inspiration, we see a departure from past Expedition tradition. Unlike the supposed Expedition spy shots we showed you nearly a year ago – which was nothing more than an SUV with an F-150's nose grafted on, this prototype's front-end styling looks softer and more aerodynamic, with a smaller grille and headlights, almost like an Escape or Edge. This kind of change would explain the additional front-end camouflage. In back, our spies rightly point out that Ford fitted a faux rear end to disguise the rear window's rake – expect the real thing to feature the angled rear window previewed on the Navigator Concept. Look at the last image in the gallery for a better idea of how the Expedition's rear window will actually look. We can't say a lot about the taillights, because of the camo, but non-LED taillights are present. We'd expect Ford to offer LEDs on higher trim levels. While the F-150's styling might not make the transition to the Expedition, its powertrains and emphasis on lightweight aluminum will. Our spies report the biggest SUV will ride on a new T3 platform and feature an aluminum body, with the F-150's 3.5-liter EcoBoost V6. Expect a ten-speed automatic transmission and start/stop tech for sure, while the smaller 2.7-liter, twin-turbo V6 could slot in as the Expedition's base engine – we're less sure on that one. And we're even more uncertain of the rumors of an Expedition Hybrid. Our spies report it could mate a 3.5-liter V6 with an electric motor(s) and battery packs for a more economical full-size SUV. Expect to see the 2018 Expedition debut in January, at the 2017 Detroit Auto Show.

EPA says fuel economy test for hybrids is accurate

The EPA says it stands behind its fuel economy test for hybrid vehicles following controversy about the testing process after Ford C-Max Hybrid customers and automotive journalists alike struggled to achieve 47 miles per gallon, the advertised mpg number, Automotive News reports. Ford responded to the issue almost two weeks ago by claiming that a 1970s-era EPA general label rule was responsible for the inaccurate mileage numbers, rerating the C-Max Hybrid's mpg numbers and offering customers rebates. Ford later said it didn't overstate the C-Max Hybrid's fuel economy and that it was surprised by the low numbers.
Ford technically didn't do anything wrong because it was following the general label rule, but agency regulator Christopher Grundler says the automaker was exploiting a loophole when it came up with the hybrid C-Max numbers, and that the testing process remains accurate. The general label rule allows vehicles that use the same engine and transmission and are in the same weight class to share fuel economy numbers, but it doesn't take into account other factors such as aerodynamic efficiency, which affects hybrids more drastically than non-hybrid vehicles. Ford originally used the Fusion Hybrid economy figures for the C-Max Hybrid and claimed the engineers didn't realize that its aerodynamic efficiency would affect fuel economy as much as it did.
