XCAR stages epic drag race between Ford GT40, GT70 and GT

XCAR has put together what it believes is a first - a drag race between Ford's legendary, Le Mans-winning GT40, the more recent GT supercar it inspired and the little-known GT70 rally car. The three mid-engined monsters were all built for very different purposes, and not surprisingly, they come to battle with very different powertrains.
The GT40 is powered by a thumping, naturally aspirated V8. This example, which looks like a Mark IV model, is likely powered by a 7.0-liter engine, although it's not entirely clear how much power it's putting down. The GT70, meanwhile, was Ford's response to the Lancia Stratos. Considering that the Lancia is one of the greatest rally cars in history and many of you are probably just hearing of the GT70 for the first time, you can imagine how much success Ford had with it. Only six were produced before a change in regulations doomed this mid-engined rally car.
The Ford GT, meanwhile, doesn't really need an introduction. 550 horsepower is on offer from a 5.4-liter, supercharged V8, which keeps the GT competitive even against more modern supercars. 60 miles per hour arrives in well under four seconds while the top speed sits at 212 mph. Not bad for a car that went out of production in 2006.

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 F-150 Raptor gets EcoBoost V6, new chassis and aluminum body [w/videos]

The Autoblog staff universally loves the Ford F-150 SVT Raptor, and the truck's about to get even better. Coming in the fall of 2016 (we'd assume as a 2017 model), the next off-road-ready pickup from Ford will boast an all-new, purpose-built, high-strength steel frame and a lightweight aluminum body that saves more than 500 pounds when compared to the current Raptor. It's six inches wider overall than the regular 2015 F-150, which both makes it look awfully mean but also aids in stability when driving fast off the road, and new LED lighting elements make it stand out when the sun goes dim. Under the Raptor's muscular hood will be a 3.5-liter EcoBoost V6 engine that will make more than the current 6.2-liter V8's 411 horsepower and 434 pound-feet of torque, though we don't have exact power figures for the next-gen Raptor quite yet. Also new will be a 10-speed automatic transmission, which will replace the current six-speed unit and ought to provide appropriate ratios for both rock crawling and high-speed desert trail running. Speaking of high-speed running, what makes the Raptor tick, perhaps more than any other single component, are its custom-designed suspension bits. Redesigned, larger Fox Racing Shocks with more suspension travel and all-new terrain management technology, combined with BFGoodrich All-Terrain KO2 tires, are the bits and pieces that allow for Baja-style off-roading. View 14 Photos The four-wheel-drive system in the next-gen Raptor will include a Terrain Management with settings for Normal driving, Street driving, Weather mode (for rain, snow or ice), Mud and Sand, Baja mode and Rock mode. According to Ford, the Raptor's new transfer case is designed to work as both a locking unit for crawling and a full-time unit for other off-road applications. A Torsen front differential will be optional. Basically, if all of this new stuff turns out to be as good in practice as it sounds in a press release, the next F-150 Raptor will only serve to separate Ford's off-road pickup even further from its half-hearted competitors.
