Hertz Penske GT latest hot Ford Mustang at the rental counter

Just a couple days after announcing the resurrection of its Rent-A-Racer program, Hertz has revealed a new car being added to its Adrenalin Collection of rental cars. To signify its new partnership with Penske Racing in NASCAR, Hertz introduced a limited-edition version of the Ford Mustang GT, officially called the Hertz Penske GT, at last weekend's NASCAR races in Daytona. If you're like us, the rental specials remind with the original 1966 Shelby GT350-H and its later homage, the 2006 Shelby GT-H.
Visually, the Hertz Penske GT starts out with a black and yellow paint and graphics scheme as well as identifying badges, and Hertz has raided the Mustang parts bin for bits and bobs like a Boss 302 front splitter and Shelby GT500 rear valence to give the coupe its own unique look. The model has also receives performance improvements including upgraded suspension and exhaust, Brembo brakes, a retuned ECU and Recaro bucket seats. As a bonus, Penske Racing's Nationwide Series No. 22 Ford Mustang has been painted to match the new Hertz Penske GT. Other cars in the Hertz Adrenaline Collection include the standard version of the Ford Mustang GT, Chevrolet Camaro SS, Chevrolet Corvette convertible and Dodge Challenger R/T. Scroll down for the official press release for the Hertz Penske GT, or you can always head to your local Hertz airport location to see if they have one on the lot.

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).

Ford Mustang challenges Lamborghini in amazing drift battle

Engines scream and tires billow with smoke as Vaughn Gittin Jr. and Daigo Saito stage a drift battle through an abandoned Japanese resort that looks like a Russian village in this stunning clip. The high-performance ballet of these amazing machines sliding around makes this one of the best videos of the year. To fight this duel, Gittin straps into his 550-horsepower Ford Mustang, and Saito meets the pony car's challenge with a drift-prepped Lamborghini Murcielago. The drivers hit a curving road and show expert car control as the men slide these very different vehicles just inches from each other. Eventually, night descends, and they add some fire to the scene to give the stunts a more apocalyptic look. The production values for this short clip are phenomenal, and the editing makes the viewer feel right in the middle of the action. If you want to get behind the scenes of this impressive display of drifting, Speedhunters did a great job capturing the event in photos. Related Video:
