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.

Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

How Ford switched gears for the all-new F-150

Editor's Note: This story is authored by Julia Halewicz, a senior editor with AOL's Custom Solutions Group. She holds a Masters in Journalism from NYU and has spent her career as an editor of various newspapers, magazines and digital outlets. Last year on the Friday before Labor Day, the 2014 Ford F-150 pickup truck came off the Dearborn assembly line for the last time. After the last seam was welded, the F-150 that had been so beloved by American consumers would begin the transition from traditional steel manufacturing to an aluminum body, and the second phase of Ford's 2007 blueprint for sustainability would begin. Jobs would be created, and Ford would deliver a stronger product to its consumers. It was a moment Ford would call the biggest in the company's 111-year history. Breaking The Mold For some, the change was almost unfathomable. How could a truck be made with aluminum, and why change what clearly was working very well for the company? "We have a saying at Ford that leaders lead," said Doug Scott, the company's truck group marketing manager. "This was an ideal product to make with aluminum-alloy, because lightweighting made so much sense for a truck, because the extent to which you could take weight out of a truck, you could add more value to the customer in terms of more towing, more payload, more durability, more efficiency – so again all this required us to be out in front further out in front that we normally would be to make sure that we would deliver on all those expectations." Ford began the planning process about five years before the first aluminum F-150 would come to market. The company had a lot of questions. What was customer acceptance of aluminum, could they build the truck, and could the truck be repaired out in the field? Finally, Ford needed to determine if there were enough materials available to support the demand for the F-Series. Aluminum vehicles aren't unusual, but had never been built on the scale of the F-150 – approximately one every minute. Ford created two prototypes to determine if the product would meet and exceed consumer expectations. Any change to the vehicle had to be justified in performance, safety and economy. An aluminum truck needed to be safer, lighter, have increased payload, haul more, and have improved fuel efficiency. After driving the prototypes, Ford knew it was ready to move forward. Once the aluminum truck was ready to build, the next challenge was quickly transforming the plant.
