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).

2015 Hennessey VelociRaptor 600 fills an F-150 Raptor-sized void

Ford is rumored to possibly debut a new F-150 Raptor at the upcoming Detroit Auto Show in January, but whether that's the case or not, Hennessey Performance is ready to fill the muscle truck niche now with its latest VelociRaptor 600 Supercharged based on the 2015 F-150. The fantastically named VelociRaptor package has been available on the regular Raptor for the past few years, taking power up to 600 horsepower or more, depending on what the buyer desired. With the latest one, the performance truck is now based on the aluminum-bodied F-150, specifically the FX4 Super Crew model with the 5.0-liter V8. "Having Ford's world-class new truck design, with a weight savings of nearly 700 pounds, our VelociRaptor 600 Supercharged will have an even greater level of performance and driving excitement," said founder John Hennessey in the company's release. The heart of VelociRaptor is the Roots-type supercharger running at 8 psi on the V8. With help from upgraded fuel injectors, a proprietary engine management system and stainless steel exhaust, it boosts grunt from a stock 385 horsepower to over 600 hp. To make sure that power gets to the road, the package also includes 33-inch BFGoodrich mounted on 17-inch Hennessey wheels. For buyers in need of more, the company offers optional parts including an off-road coilover suspension, different front and rear bumpers, a winch, LED light bar and Brembo brakes. Speaking to Autoblog, Hennessey said he feels confident that the latest VelociRaptor could do high-four-second sprints to 60 miles per hour, compared to the outgoing model in the low-five-second range. Prices for the VelociRaptor start at $73,500, which includes the donor F-150, and orders are open now. Actual deliveries should start by March at the latest, according to Hennessey. The company also plans to offer a similar package for EcoBoost F-150s later. Scroll down to read the full announcement about this muscle truck. Introducing the 2015 Hennessey VelociRaptor 600 Supercharged Texas tuner adds power and improved off-road capabilities to Ford's all-new aluminum bodied pick-up trucks December 16, 2014-For immediate release Sealy, Texas-For the past five years, Ford F-150 truck enthusiasts have had the special opportunity to own the SVT Raptor. With 411 hp and baja pre-runner capabilities, the Ford Raptor was one of the most capable 4x4's ever built. Sadly, Ford Raptor production has ended, leaving a void in the market for 2015.

10 most memorable cars and SUVs of 2019

It's no surprise that a car reviewer will drive a large number of cars over the course of a year. Indeed, when the clock strikes midnight on Dec 31, I will have driven 75 new cars, trucks and SUV this year (and one old Peugeot) over the course of weekly evaluation loans and first drive events. That sure seems like a lot. Some definitely got more attention than others, and some came and went without leaving much of an impression – I completely forgot I drove a Kia Forte. Yet in the spirit of this day, I thought I'd pick the 10 that I would love to see under the Christmas tree tomorrow morning. You know, just in case you were looking to get me something. I'll also throw in a couple disappointments that were memorable for the wrong reasons. They'd get sent back to the store on Boxing Day. Lexus LC 500 Pictured below and resplendent in its Flare Yellow metallic paint, the car that would reach highest on my list is the divine Lexus LC 500. As a devout lover of GT cars, the LC ticks all the boxes. Muscular and characterful engine? V8, check. Beautifully made and memorable interior? It's gorgeous, to hell with Remote Touch. Check. Comfortable and reasonably practical? Superb seats and, uh, yeah. Makes me want to stand there and stare at it? You bet. Though I long figured my heart would say LC but my head "Porsche 911," after this go-around, that's no longer the case. LC, pretty please. 2020-lexus-lc500-f34-2 View 19 Photos Polestar 1 I actually feel lucky that I got to drive the Polestar 1. Only 150 will be produced each year, and it's a far more special thing than it would initially appear. And that's despite initially appearing to be a beautiful, classic two-door GT car with a roof so rakish it's only possible because it's made of carbon fiber. That itÂ’s a massively powerful plug-in hybrid with more all-electric range than any other PHEV is a thick dollop of whipped cream on a slice of Toscakaka. You know, Swedish dessert, Swedish car. Fine, I'll stick to Ikea references.  Polestar1_Launch_SanFrancisco-0014 View 44 Photos Volvo V60 Cross Country Speaking of Sweden, did I drive this car off the road there? Sure did! And despite this, the V60 Cross Country scratches that certain wagon itch and looks sensational to boot. I wish it were available with the T8 plug-in hybrid powertrain, but it's best not to get greedy at Christmas.
