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.

Watch this week's Top Gear America used-car challenge

Top Gear America is back for the penultimate episode of the first season. Used car challenges were some of the highlights of the original UK edition. In our exclusive clip, Tom Ford, Antron Brown and William Fichtner run their $7,000 sports cars in a drag race. As expected, the trio chose very different cars for the challenge. Watch the video to see if a Subaru WRX's all-wheel drive can overcome a power deficit to beat a Ford Mustang and a Chevy Corvette. Brown and Fichtner also spend some time relaxing with an old Jeep Wagoneer. Like them, we're really hoping Jeep will bring back the Wagoneer nameplate. Brown also drives a Maserati Levante, proving that not all family cars need be boring. This week's guest star is actor, rapper and former host of Pimp My Ride, Xzibit. Top Gear America airs Sundays at 8 p.m. Eastern on BBC America. Related Video: Celebrities TV/Movies Chevrolet Ford Subaru Top Gear exclusive top gear america

Amazon is showcasing its big push into cars and transportation at CES

From making cars talk using Alexa's voice to managing data from factories full of robots, Amazon wants a big piece of the action in transportation, and next week at CES will unveil more about its strategy to achieve that goal than ever before. The Seattle retail and cloud services powerhouse plans to use the annual technology show in Las Vegas to unveil its plan to be a major player in self-driving vehicle technology, connected cars, electric vehicles and management of the torrents of data generated by automakers and drivers, company executives told Reuters. Amazon Web Services, which provides large-scale cloud computing and data management services, is central to Amazon's strategy. "We really are extending ourselves more and more out in the ecosystem from manufacturing to connected car," Jon Allen, head of professional services in Amazon Web Services' automotive practice, said in a telephone interview. "The takeaway message on this is if you go to CES this year we really are taking it as a 'One Amazon' view." Until now, Amazon has shown its transportation strategy to investors — and rivals — one piece at a time. Amazon has invested in self-driving software startup Aurora. It also has signed deals with automakers to deliver packages to vehicle trunks, help develop electric vehicle charging networks and use AWS to network their factories. The Seattle company will share the CES stage with partners such as virtual reality firm ZeroLight, electric vehicle startup Rivian, Canada's BlackBerry Ltd and video game software development company Unity Technologies. "It's our attempt to weave everything together in a single experience for our customers," Dean Phillips, AWS' automotive technical leader, told Reuters. "Customers don't distinguish AWS from Alexa from Amazon.com. It's Amazon."   Related: As GM readies Alexa convenience for vehicles, we ponder its dark side   At CES, ZeroLight and GM's Cadillac will demonstrate how they are partnering to develop an online vehicle configuration experience that will allow high-fidelity images of vehicles that consumers build online to be taken with them on visits to dealers, Phillips said. The process can open the door to dealers better meeting customer needs by knowing what users focused on when building their dream car. It has already boosted profit per vehicle at Volkswagen's Audi brand by an estimated 1,200 euros ($1,340), he said.
