USPS releases hot rod stamps to speed up your delivery

After one of the worst winters in recent memory for much of the country, summer is finally here. It's time to drop the top, open the sunroof or at least put down the windows and take a long drive. The United States Postal Service is celebrating the season's sun in automotive style with two new hot rod Forever stamps.
Both stamps depict classic '32 Ford hot rods. One shows the car from the front at a low angle in red (pictured above), while the other depicts the car from the back in black with flames running down the side.
To introduce the new stamps on their first day of availability, the USPS went straight to the source at the National Street Rod Association Street Rod Nationals in York, PA. They were unveiled by Postmaster General Patrick Donahoe, Car Crazy host Barry Meguiar and NSRA Special Events Director Jerry Kennedy.

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).

1969 Ford Talladega GPT Special is a SEMA showstopper

Rad Rides by Troy has unleashed upon the SEMA crowds this custom 1969 Ford Torino Talladega GT Special, and it's a beauty. The car calls to mind the classic Holman Moody stock cars that circled NASCAR tracks in the late 1960's, driven by the likes of Mario Andretti, Dan Gurney and David Pearson, who won the Grand National title in both 1968 and '69 in a Ford Torino.
Even though it has plenty of stock-car influence, there's nothing retro about the car's design or powertrain, other than the fact that the engine is based on a Ford Boss 429 block. Fuel injection, aftermarket aluminum heads and a high-tech custom computer system combine to send 750 reliable ponies to the rear wheels through a Tremec five-speed manual transmission. Brakes measure 14-inches all around, with six-piston Wilwood calipers up front and four-piston units out back.
There's custom bodywork abound, painted in a two-tone Tennessee Whiskey Gold and Daytona Sand finish. Check out all the amazing details in the image gallery below, and scroll down to read all about it in designer Troy Trepanier's own words.
