Watch these Australian Ford and Holden muscle cars duke it out

Australia's Motoring has put together a little video on two of the great performance vehicles available down under - the Holden VF Commodore HSV GTS and the Ford Falcon FPV GT R-Spec. And while both FPV and the Falcon might be on their way out, there's still plenty of time for a little head-to-head comparison between the two.
The cars aren't all that well evenly matched, though. The Ford boasts a 5.0-liter, supercharged V8, which the Aussies measure out at 449 horsepower and 420 pound-feet of torque. The HSV, though, with its Corvette-derived, 6.2-liter, supercharged V8 is just too powerful - 576 hp and 545 lb-ft of torque.
Predictably, it doesn't end too well for the Ford. As the guys from Motoring point out, the new VF Commodore is just too new and too good, with its extra power and its adaptive dampers (GM's excellent MagnaRide). Interestingly, Motoring did point out that the Holden's electric steering is better than the Ford's hydraulic steering, which is a lot like a Porsche purist saying they prefer water-cooled engines to air cooled.

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 Focus PHEV on the way?

A refreshed Ford Focus is in the works and that means a few details are leaking out. Spy shots from last month indicated the Focus will have a gaping grille just like its "One Ford" global C-segment comrade, the Fiesta. While Ford is being quiet about it, the Focus could also be getting an "Energi" option, joining the C-Max Energi and Fusion Energi in Ford's plug-in hybrid family. The Focus will likely use technology originated in the C-Max Energi that combines a 2.0-liter gasoline engine with an electric motor capable of a 20-mile range, according to Autoexpress. The pure electric Focus is expected to stay in the lineup despite its slow sales; its price range should be similar to what's on the market now. The third-generation Focus looked good enough to become the top-selling nameplate in the world in 2012. Some exterior changes to look for in the Euro-spec model at the Geneva Motor Show in March include a reshaped hood, front wing endplate and rear bumper. Interior spy shots have hinted at an updated dashboard design and a simplified, less cluttered control panel with updated climate controls. Under the hood, there are quite a few power options rumored to be available - a gasoline EcoBoost with up to 123 horsepower and two turbo-diesel TDCI options, a 1.6-liter or 2.0-liter mills that would produce between 94 hp and 161 hp. Then there are new 1.5-liter diesel and 1.5-liter EcoBoost gasoline variants that meet regulations in China, Brazil and Russia.
