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.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.

Ford's new Focus RS hatches hot and heads for America

The hot hatch market is heating up, and heating up fast. What you see here is Ford's new challenger for pocket-rocket supremacy, the third iteration of the breed and the 30th model to wear the Rallye Sport designation. But perhaps best of all, it will be the first time Ford will offer a new Focus RS in America. Following yesterday's leak, the latest Ford Focus RS is now ready to step out into the light and light up its tires. Answering the call is the same 2.3-liter EcoBoost turbo four as you'd find in the new Mustang, but upgraded with a new low-inertia twin-scroll turbocharger, larger compressor and intercooler, freer-flowing intake, large-bore dual-pipe exhaust with electronically controlled valve and upgraded internal components. The result is a 6,500-rpm redline (closer to that of Ford's atmospheric performance engines) and an output quoted as "well in excess of 315 horsepower" – which is already 5 more than the EcoBoost Mustang and a good 63 more than the existing Focus ST. Power is transmitted to the tarmac through a new performance-focused all-wheel drive system with torque vectoring that can send as much as 70 percent of available twist to the rear wheels (and as much as 100 percent between them). The system works in tandem with the brake-based torque vectoring system and stability control, and will even divert torque to the outside rear wheel under cornering to keep it flat and under control while reducing understeer. Those still suspicious of dual-clutch gearboxes will also be pleased to read that Ford has stuck with a conventional six-speed manual. We'll reserve judgement on the inclusion of the electric power steering until we get a chance to drive it, though. Of course the small team of global Ford Performance engineers who developed the new Focus RS – and the Gymkhana legend Ken Block who consulted on the project – didn't just tinker with the powertrain and leave it at that. The suspension features stiffer spring rates, bushings and anti-roll bars than the Focus ST, augmented by two-mode switchable dampers. 19-inch alloys wear Michelin Pilot Super Sport rubber, with optional Pilot Sport Cup 2 semi-slicks for track-day enthusiasts. Ford has yet to detail the brakes on its new hot hatch, but you can bet they've been upgraded as well.
