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.

Focus STs for SEMA include Lotus and Gulf liveries, rally-fied police car

Ford, as we mentioned on Saturday, is pulling out all the stops for November's SEMA show, bringing 57 vehicles to the Las Vegas event. Ford will be staggering the release of its SEMA flotilla, though, so expect to hear a lot about the new additions to the fleet in the weeks to come. We already showed you the Fiesta, Fiesta ST and Mustang models that made up the first batch of SEMA cars. Next up, we have a quartet of modded Focus STs joining Ford's SEMA roster.
Our first Focus ST (pictured above) sports the legendary livery of Gulf Racing. The orange-on-blue scheme, which Ford helped make famous at the 24 Hours of Le Mans, has been updated for 2013, with a more vibrant blue. This ST was built by Universal Technical Institute, while the exterior was done by Neil Tjin of Tjin Edition. Side exhausts, a Vortech supercharger and a Motiv Concepts high-flow cat allow the ST to breathe a bit easier, while Forgestar wheels contrast well with the iconic paint scheme.
Focus ST number two has been done-up by PM Lifestyle and is inspired by "Southern California car culture." Sporting a sleek, pale blue paint job, there's also no shortage of carbon fiber on the car's exterior. The 2.0-liter, turbocharged, four-cylinder engine has been massaged by the likes of Banks Power, COBB Tuning and Ford Racing, while the suspension is wearing a shiny, new set of coilovers and sway bars. The meaty brakes, tucked behind 19-inch, Rotiform wheels, come from Wilwood, while the cabin has been fitted with a pair of Sparco Chrono seats and five-point, Schroth harnesses.

2015 Ford Mustang EcoBoost loses big power on 87 octane

The 2015 Ford Mustang with the 2.3-liter EcoBoost four-cylinder is a pretty potent package on paper. With 310 horsepower and 320 pound-feet of torque, it boasts better performance numbers than the 3.7-liter V6, but with better fuel economy as an added benefit. However, if you're in the market for one of these boosted 'Stangs, you should probably keep in mind that it really prefers to gulp premium, 93-octane fuel. It can drink 87-octane swill in a pinch, but you're going to find significantly less power underfoot when pulling away. While it's not shocking that the ponies are dialed back with a lower grade of gasoline, an alleged page from a Ford training manual obtained by Mustang 6G purports to show just how much power is lost, though. According to this document, the 2.3-liter EcoBoost makes 275 horsepower and 300 pound-feet of torque when running on lower octane fuel. That's a substantial reduction of about 11.3 percent compared to when the engine drinks 93 octane. Interestingly, according to Mustang 6G, that finding was a bit better than expected, because a Ford engineer reportedly said power would be down about 13 percent without altering peak torque. In speaking with Autoblog, Paul Seredynski of Ford powertrain communications, objected to part of this document. While he couldn't confirm the specific losses listed for the Mustang EcoBoost, "torque remains unchanged" with lower octane gasoline, Seredynski said. He speculated this training manual page was "possibly from before the engine was certified" and therefore showed incorrect figures. Serendynski did confirm that the automaker recommends using 93 octane, and like all modern engines, the software adapts if it's lower. "Peak power would be reduced" by using a lesser grade, he confirmed.
