Focus STs for SEMA include Lotus and Gulf liveries, rally-fied police car

Ford, as we mentioned on Saturday, is pulling out all the stops for November's SEMA show, bringing 57 vehicles to the Las Vegas event. Ford will be staggering the release of its SEMA flotilla, though, so expect to hear a lot about the new additions to the fleet in the weeks to come. We already showed you the Fiesta, Fiesta ST and Mustang models that made up the first batch of SEMA cars. Next up, we have a quartet of modded Focus STs joining Ford's SEMA roster.
Our first Focus ST (pictured above) sports the legendary livery of Gulf Racing. The orange-on-blue scheme, which Ford helped make famous at the 24 Hours of Le Mans, has been updated for 2013, with a more vibrant blue. This ST was built by Universal Technical Institute, while the exterior was done by Neil Tjin of Tjin Edition. Side exhausts, a Vortech supercharger and a Motiv Concepts high-flow cat allow the ST to breathe a bit easier, while Forgestar wheels contrast well with the iconic paint scheme.
Focus ST number two has been done-up by PM Lifestyle and is inspired by "Southern California car culture." Sporting a sleek, pale blue paint job, there's also no shortage of carbon fiber on the car's exterior. The 2.0-liter, turbocharged, four-cylinder engine has been massaged by the likes of Banks Power, COBB Tuning and Ford Racing, while the suspension is wearing a shiny, new set of coilovers and sway bars. The meaty brakes, tucked behind 19-inch, Rotiform wheels, come from Wilwood, while the cabin has been fitted with a pair of Sparco Chrono seats and five-point, Schroth harnesses.

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).
