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).

Hennessey showcases F-250 VelociRaptor SUV

With automakers embracing smaller and smaller crossovers with each passing year, it'd be all too easy to forget about the Ford Excursion. Bigger than the Expedition (or just about anything else on or off the road), the Excursion was based on Ford's Super Duty truck chassis to put even the likes of the Chevy Suburban, Nissan Armada, and Toyota Sequoia to shame. It ceased production ten years ago now, but Hennessey is bringing it back – sort of. Feast your eyes on the Hennessey VelociRaptor SUV. The design calls for a very fullsize, truck-based sport-ute based on the Ford F-250. Only instead of a pickup bed, it's got four proper side doors and a covered cargo bay with a pair of barn doors at the back. Hennessey will fit it with three rows of seats to accommodate seven or eight passengers, and of course it'll offer a range of upgraded engines as well. What starts out with a 6.2-liter V8 producing 411 horsepower can be supercharged all the way up to 600 or even 650 horses. For those who don't want to spend their life's savings at the pump... well, this probably isn't the right choice of automobile, but Hennessey will offer an enhanced 6.7-liter PowerStroke diesel with 440 hp and 880 pound-feet of stump-pullin' muscle. Naturally there'll be other visual and mechanical upgrades on offer as well, but none of this will come cheap – or fast for that matter. Hennessey will take six months to put one together, and demand nearly $160,000 for the conversion.

Fiat Panda by M-Sport a one-of-a-kind rally car

English racing and engineering firm M-Sport is probably best known for the Bentley Continental GT3 endurance racer and the Ford Fiesta R5 customer rally car. Since building the first of 294 Fiesta R5 Mk. I cars in 2013, the fleet of pint-sized competitors has won a total of more than 950 races. So when a longstanding M-Sport customer asked the company to do something special with a clapped-out, 1990s-era Fiat Panda that would retain the car's Panda-ness but also make it a stonking rally car, M-Sport decided to combine the Italian with the Anglo-American. The result is the Panda by M-Sport, a widened Panda bodyshell lowered atop a Fiesta R5 chassis and engine. Otherwise known as Panda'monium. Or Pandiesta, if you're tipsy. Just fitting the skinny Fiat over the tube-frame chassis meant widening the Panda's body shell by 14.2 inches; that slick grille is actually made of two Panda grilles to gain the required width. That surgery helps maintain the original Panda's silhouette, but more was needed to slide the Fiesta's wider track underneath. More latitudinal stretch was provided by the box-section wheel arches that, up front, flow into a front bumper that is half snowplow. In the longitudinal direction, the Pandiesta's wheelbase is 12.6 inches longer than that of the stock Panda. The Ford's 1.6-liter EcoBoost four-cylinder lives under the hood. It sends nearly 300 horsepower and 332 pound-feet of torque to four Pirelli P Zeros through a five-speed sequential transmission and two custom differentials. The new rear diffuser and single, central exhaust convey the seriousness of the endeavor. Hand-embossed lettering spells "PANDA 4x4" on the rear hatch in case anyone has questions about this having as much capability as the standard Panda 4x4. The interior is all Fiesta R5 save for the Panda-mimicking instrument panel and the co-driver's footrest. The latter is also inscribed with the word "PANDA." Despite the license plate, there's no question of street legality here, or rather illegality. M-Sport says the Panda'monium is ready to do any special stage on tarmac or gravel. Seems this is also the car that launches a new division for customer creations called MS-SV, which is M-Sport Special Vehicles. You can watch M-Sport owner Malcom Wilson take you on tour of the Panda by M-Sport in the video at top, and check out what the finished product can do on a track here.  Related Video: This content is hosted by a third party.
