Leno talks racing with NASCAR racer Joey Logano

Jay Leno has to be under significant pressure knowing the appetite his fans have for a new Jay Leno's Garage video every week. This time, Jay takes a break from his usual format (something he's been doing with some frequency as of late) and goes back to his roots as a talk show host. There's no classic in the garage his episode with an interesting story to tell and a sumptuous exhaust note. Instead, the focus is purely on interviewing 23-year-old NASCAR racer Joey Logano about what it's like to be a racecar driver in his Ford Fusion.
Logano started racing at the tender age of six and has risen up the circle-track ranks to the big show of the NASCAR Sprint Cup. The two of them talk about what it's like to compete in the sport today compared to yesteryear, and Logano shares some racing anecdotes. Of course, they also get into what it's like to be on the racetrack controlling a car with about 850 horsepower, a four-speed manual transmission and brakes without any power boost. Scroll down to watch the video.

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 Mustang-based Saleen S302 to boast as much as 640 hp

The Ford Mustang is obviously a famous performance vehicle in its own right, but it often works even better as a platform for the aftermarket to upgrade. With the all-new 2015 model just now hitting the scene, the famous tuners at Saleen are getting their improvements for the new pony car ready for the world. After recently teasing it, the specs for its fresh S302 model are officially here, along with a first look at it in profile.
Of course, the biggest question on everyone's mind is how much power the company can get from the Mustang's V8. With the 2015 V8 model rated at 435 horsepower and 400 pound-feet, Saleen expects to bump the Ford factory numbers slightly to 450 hp and 410 lb-ft in naturally aspirated form, or with the benefit of a supercharger, it will rocket the engine's output figures to 640 hp and 565 lb-ft. No matter which powerplant a buyer chooses, there are a wide variety of available final-drive ratios with a six-speed manual or automatic gearbox.
Available as either a coupe or convertible forms, Saleen will offer its S302 in three trim levels - White Label, Yellow Label and Black Label. The White Label is the only naturally aspirated one of the bunch, but it still benefits from upgrades like a new exhaust, limited-slip differential, improved suspension, heat extractor hood and rear wing.
