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.

Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

Road tripping in a Ford Fusion Energi PHEV

Following my earlier Chevy Cruze Diesel trip and recent press-launch drives of Volvo XC90 and Hyundai Sonata plug-in hybrids, an opportunity arose for another road trip. I wanted to do it in a plug-in hybrid, primarily to learn whether its higher price vs. gas-powered and conventional hybrid versions of the same vehicle – is justified by its capability to operate as an EV, burning no fuel at all with its engine off, at least for short distances. I've been skeptical of plug-in parallel hybrids. As I've written before, I've been skeptical of plug-in parallel hybrids because they are generally good for very limited electric miles (typically 10-15, depending on driving style, terrain, and temperature) at fairly leisurely speeds before their engines kick in. But I've recently spent time in two new examples – the 2016 Volvo XC90 T8 and the 2016 Hyundai Sonata PHEV – that offer more EV range, mostly because they tote bigger (thus more expensive) batteries. Both promise 24-25 miles of battery-only range, and the latter can recharge on the fly. Unfortunately, neither was yet available for my July road trip, nor was a Honda or Toyota plug-in, but Ford anted up a Fusion Energi borrowed from its Marketing department. "The state-of-the-art lithium-ion battery and electric motor combined with the gasoline engine offers maximum efficiency," says Ford about it. "This strategy offers the best of both worlds, providing the 2016 Ford Fusion Energi the capability to be driven as an electric vehicle for short trips and as a hybrid for longer trips." I've been a fan of Ford's Fusion since the first-generation debuted a decade back, and the handsome Gen II version launched for 2013 has been Detroit's best answer to the Honda Accord/Toyota Camry/Nissan Altima Japanese juggernaut in the popular US mid-size sedan segment. Beyond its leading-man looks, it offers an array of highly-functional features (some exclusive), a choice of three gas engines (a base 2.5-liter four and 1.6-liter and 2.0-liter direct-injected, turbocharged EcoBoost fours) and both parallel and plug-in parallel hybrid versions. The regular hybrid originally boasted 47 mpg before Ford adjusted it to be more realistic. The gas engines drive through a 6-speed automatic transmission (a 6-speed manual is standard with the 1.6-liter EcoBoost), the hybrids through an electric continuously variable transaxle (eCVT), and all-wheel drive is available with the 2.0-liter EcoBoost four.
