Jay Leno drives postcard-perfect '32 Ford Highboy Roadster

At the turn of the century, it was arguably the Honda Civic that best defined inexpensive performance tuning, and in the '50s it was the Tri-5 Chevys. One of the earliest platforms to gain a huge following among young people looking for a cheap way to go fast was the classic '32 Ford Highboy Roadster. This week, Jay Leno's Garage looks at one of the very first vehicles that defined the look of the hot rod heyday.
This '32 Ford was built in the '40s and graced the cover of the fourth issue of Hot Rod Magazine back in 1948. All of the hot rods that you see shining at car shows today owe a serious debt of gratitude to this roadster. It bears all of the cues that define the look, including a notched frame and hidden door hinges. Under the three-piece hood is a flathead V8 boasting all sorts of period modifications, including copper cylinder heads. It was seriously fast in its era too, and proved it by reaching 112.21 miles per hour on a dry lakebed in 1947.
These days, this hot rod is on display at the Petersen Automotive Museum. Although, if you can't make it to California to see it, the United States Postal Service is celebrating this Ford with one of its two hot rod Forever stamps. Like Jay says in the video, in terms of hot rodding, "it all comes back to this." Check out the video to learn more about this rolling piece of tuning history.

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.

2015 Ford Mustang to offer solid-rear axle, sort of

One of the biggest knocks against the last Ford Mustang was its solid-rear axle. Not one to actively court criticism, Ford dutifully swapped out the old-fashioned rear end for something a bit more modern in the redesigned 2015 Mustang, adding an independent rear suspension across the board.
While an IRS Mustang is great news for those that value handling and ride comfort, there's one big group that it's bad news for - drag racers. See, a solid-rear axle is a big deal for drag racers, because not only is it more durable and cheaper, but it's better for the hard launches that can make or break a race.
To satiate this vocal demographic, Ford will sell a body-in-white version of the Stang, complete with a nine-inch rear axle, that will debut at the 2014 Performance Racing Industry show. The news came from gas2.org, which cited an unnamed employee of Ford Racing at this year's PRI show.
