Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

Ford Shelby GT350 Mustang to cost $52,995?

The 2015 Ford Shelby GT350 Mustang was one of the shining stars of this year's Los Angeles Auto Show. And the Blue Oval's latest muscle car might even have reason to burn a little brighter if a recent rumor about its price proves true. Best of all are rumors that an even more potent version of the Shelby is potentially on the way. According to Horsepower Kings citing unnamed Ford sources at the LA Auto Show, the 2015 GT350 carries a starting price of $52,995, and the Tech package adds a further $2,995 on top of that. There's also the claim of a Track package for an undisclosed price. However, it doesn't look like LA is the last we'll see of the newest Shelby because the source also alleges that a top-rung GT350R is under development with bigger brakes, modified aerodynamics and sportier tires. This rubber-burner is reported to be unveiled at the North American International Auto Show in Detroit in January. Assuming these claims are correct, it puts the Shelby in fighting form against its two Chevrolet Camaro rivals. Ford reports that the GT350's 5.2-liter V8 pumps out over 500 horsepower and more than 400 pound-feet of torque. At $52,995, it would undercut by a couple of grand the $55,505 (before destination) base price of the 580-hp 2015 ZL1. The super 'Stang might also beat the 505-hp Z/28 with its power rating, while being vastly cheaper than the track-focused Camaro's $72,305 price. This could be quite the performance shoot-out.

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).
