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.

Toyo Tires will bring another wild catalog of rides to SEMA

Toyo Tires carts all kinds of toys to SEMA every year, the rubber company planning another 30 or so automotive exhibits this year in two locations. One of them, the Baja 911, comes with a pedigree not usually associated with the bewildering wares hawked at the Las Vegas show. TJ Russell was once lead fabricator for Singer Vehicle Design, now he's the head of Russell Built Fabrication in Sun Valley, CA. Sticking with the marque he knows well, Russell started with a 1991 Porsche Carrera 4 cabriolet, fitted the interior with a full roll cage, then built a hardtop around it to design a desert runner channeling the old Rothmans safari 911s. Underneath that bodywork lives a box-plate trailing arm suspension with 12 inches of travel, working 15-inch Fifteen52 FIA-approved Gravel wheels and 30-inch Toyo Open Country A/T II tires. Power comes from a purpose-built 3.8-liter air-cooled flat-six with about 350 horsepower — 100 hp more than stock — in a car that weighs 400 pounds less than the original. Oh, and as documented on Instagram with the tagline "All race outside, all business inside," the interior's full of quilted, cross-stitched leather, and Toyo says Russell's going to do a low-volume run of the Baja 911 starting early next year. ruffian-ford-mustang-sema-01 View 10 Photos Chris Ashton built a 1970 Ford Mustang Fastback called the Ruffian Mustang, inspired by the Trans Am Racing Series. The exterior changes are more subtle than one might think – the chin spoiler, hood scoop, and side mirrors are barely exaggerated versions of those on the original car, the intake vents astride the front lights and the steel bumpers teleported from 1970. Changes outside include de-chromed and flush-mounted glass, vented hood, front fenders that are dropped an inch, rear fender vents, dual side-exit pipes, and gargantuan fender flares over staggered Signature One wheels and Toyo Proxes 888 tires. The interior's fitted with a roll cage and race car workings. In spite of the Boss 427 badging, the engine's a 625-hp Chevrolet LS3 V8. button-built-ferrari-355-sema-01 View 13 Photos The Button Built Ferrari BB355TT picks up from last year's stanced BB328GTS widebody that gave many Internet denizens heart attacks. Laid up on a 1999 355 Berlinetta, the BB version appends a widebody kit designed Mitchell Button, rendered by Khyzyl Saleem and drenched in Azzuro la Plata, a color from Ferrari's Scagliette palette first used on a 1967 275GTB Le Mans racer.

2020 Ford Super Duty Tremor vs. 2020 Ram 2500 Power Wagon: How they compare on paper

(Editor's Note: Due to inconsistencies in manufacturer reporting methods for ground clearance, an earlier version of this article stated the Ram Power Wagon's "ground clearance" to be 14.3 inches when in fact that is its "running clearance," which is deemed the ground to the lowest point of the truck MINUS the axles. The numbers below now reflect true ground clearance, or the ground to the lowest point of the truck, period. The chart and text have been updated to show both measurements for maximum accuracy and clarity.) For several years, the Ram 2500 Power Wagon has been the unquestioned king of heavy duty off-roaders. But competition is coming, and some of the strongest is from the 2020 Ford Super Duty Tremor. We decided to take a look at these trucks' specs and features to see how they compare in the realm of capability. The raw numbers are below along with some notes on each truck's unique features that go beyond the spec sheet. Off-road capability While both of these trucks boast impressive clambering abilities, each with particular strengths. The Super Duty Tremor earns points for better ground clearance and axle clearance, as well as approach angle. Some of the credit goes to the larger 35-inch tires and a shortened front air dam. On the other hand, the Power Wagon leads the Ford in departure angle, and in the ramp travel index. The latter is largely the result of the Power Wagon's electronically disconnecting sway bars, and for those unfamiliar, the ramp travel index measures articulation by having a truck drive one wheel up a ramp with the other on the ground. The farther the truck goes with the ground wheel in contact with the, well, ground, the better the score and the better the articulation. Numbers aren't everything, though. It's important to look at the equipment each truck offers, and things are closer, here, but the Ram still has an edge. Both feature off-road-friendly solid axles at both ends, but only the Power Wagon has fully locking differentials front and rear. The Tremor has a locking rear differential while the front is a limited-slip differential. The Power Wagon comes standard with a 12,000-pound integrated Warn winch, whereas such a winch is an option on the Tremor. The Tremor has its own unique features, though, including the 35-inch tires rather than the Ram's 33-inchers, and it has Ford's fancy off-road cruise control function called Trail Control. Both trucks have shocks and springs tuned for off-road use.
