Signature Edition Ford Shelby GT500 Super Snake to get limited production run

The upcoming Ford Shelby GT350 Mustang keeps grabbing a horde of headlines thanks in no small part to the pony car's 5.2-liter V8 with a flat-plane crankshaft, magnetic dampers and other go-fast goodies. However, as the new contender enters the ring, Shelby American is saying goodbye to the old GT500 and the company's even more powerful Super Snake version with its new Signature Edition model. Limited to a total of 50 conversions on 2007-2014 coupe or convertible GT500s, the Shelby American Signature Edition packages some of buyers' most common choices into a single vehicle with a few extra touches, as well. The heart of it all is a 3.6-liter Kenne Bell supercharger to replace the V8's standard blower and take power up to a claimed 850 horsepower for the latest models. To keep things running at the proper temp, the mill gets an upgraded radiator, heat exchanger and aluminum cooling tanks, too. The rear brakes are also improved to slow this stallion down. In addition to the boosted power, buyers get some extra style. These special Super Snakes are available in all of the colors available on them from Ford, plus a range of shades for the stripe, and the wide body package can also be added as an additional option. The limited version wears 20-inch forged wheels from Weld that are 9.5-inches wide at the front and 10.5-inches at the rear and feature Signature Edition center caps. Inside, there's a commemorative badge with Shelby's signature on the airbag cover and Signature Edition floor mats. Finally, customers get a day training at the track to learn how to control this beast as part of the package. Orders for the Signature Edition are being accepted through January 31, 2015, and the modded model is priced at $44,995.00, which is in addition to the price of the stock GT500.

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).

Expert: 54.5 mpg CAFE standard can be reached without many plug-ins

Johnson Controls executive Brian Kesseler isn't likely to get any holiday presents this year from Nissan chief Carlos Ghosn or Tesla Motors head Elon Musk, but lots of other folks might be happy with what he has to say about automakers' efforts to reach stricter fleetwide fuel-economy standards. Speaking at the Automotive News World Congress, Kesseler said automakers wouldn't need to sell an extensive number of plug-in vehicles in order to meet the 54.5 mile per gallon Corporate Average Fuel Economy (CAFE) standard the US government set in 2012 for 2025 model-year vehicles. In fact, he said, components such as stop-start engine technology, turbochargers and direct injection may actually do the trick. Already, things like smaller engine sizes and lighter cars are already playing major roles in spurring fuel-efficiency gains. Of course, Johnson Controls sells batteries specially built for stop-start systems, so Kesseler does have a bit of skin in this game. The 54.5-mpg CAFE standard equates to about a 40-mpg "real world" fuel-efficiency level. To put that into perspective, the Environmental Protection Agency (EPA) said in a report late last year that model-year 2013 average fuel economy was an even 24 mpg. That was up from 23.6 mpg for the 2012 model year and 22.4 mpg for 2011.
