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.

2016 Jaguar XF First Drive [w/video]

Jaguar has never had a problem with style or driving joy. Every generation of the British brand's vehicles – with excuses made and accepted in advance for S-Type and X-Type and other outliers – has offered compelling styling and great performance. New kid XF was no exception when it was introduced in 2007. The car's sheetmetal pointed the way forward for the fully up-to-date range we see now, and its confident engines and handling chops were on pace with the best Bimmers, Benzes, and Cadillacs. The first-generation XF made some hay for Jaguar, selling around 280,000 copies through 2014. But those annualized rates still represented a blip on the luxury midsize radar when viewed against the backdrop of the German Three's numbers. Part of that sales story has been down to the E-Classes and 5 Series of the world being consistently excellent, to be sure. But a lot of the blame can be found in Jaguar's historic weak spots. Grace and pace the brand had in spades, but consumer perception of quality and reliability just weren't there, pricing was typically near the top of the class, and the residual values of the cars were low (a combination of all three factors, most likely). Of course, Jag would love to sell a few more cars. But this time, instead of simply building a great-looking, great-driving new XF (which is absolutely the case), the brand is doing some clever non-engineering-based things to put more big cats in more garages than ever before. The tradeoff of very good ride quality is worth the minute amount of roll. After flying all they way to Spain – Pamplona and the Navarra Circuit, by way of Barcelona and a Range Rover adventure you'll hear about soon – I would be remiss not to tell you how the new XF goes down the road. Some 150 kilometers (93 miles) of motorway and challenging b-roads lie between the city with that annual livestock problem and the 2.44-mile, FIA approved racecourse. A route that led me to understand that this XF, in my case the 380-horsepower XF S, has gained more than it has lost in the generational changeover. The company is fully committed to aluminum for its midsizer, with the new car now using a body structure that's 75-percent built from the stuff. I'm told that means a body in white that weighs just over 600 pounds, and an overall weight savings of 11 percent. Body stiffness has been raised by 28 percent in the process.

Weekly Recap: Automakers rethink the definition of luxury

Variety is the spice of life, but it's becoming a prerequisite for luxury carmakers in the ultra-competitive US market. The Detroit Auto Show was strong evidence of this reality. It's not enough to offer attractive and well-appointed cars and SUVs anymore. Luxury brands that want to be competitive need to invest in everything from high-powered supercars to clever hybrids. To be relevant, you need to be green and mean – and everything in between. As General Motors product chief Mark Reuss said after the reveal of the 640-horsepower Cadillac CTS-V: "We are not leaving anything on the table." He was speaking for Cadillac, but he might as well have been speaking for the luxury car market. The CTS-V debuted in Detroit about an hour after Lexus surprised showgoers with the reveal of the RC F GT3 race car and then announced ambitious plans to return to competitive racing. That almost overshadowed the fact Lexus had just revealed another potent addition to its growing F line, the 467-hp GS F.

Strong competition from all corners has forced automakers to refine and expand their lineups in ways unforeseen even a few years ago. Case in point: Mercedes-Benz finally has an answer to the BMW X6, rolling out the GLE coupe in Detroit. The X6, which blends coupe-like styling cues with some of the functionality of an SUV, debuted in 2008. Back then it was a punchline, but seven years and more than 260,000 sales later, the X6's success has compelled Benz to respond. Mercedes – one of the strongest proponents of diesel technology – also debuted the C350 plug-in hybrid sedan, which promises a range of 20 miles on electricity, though fuel economy figures were not announced. The car pairs Mercedes' well-received 208-hp turbocharged four-cylinder with an electric motor for total output of 275 hp and 443 pound-feet of torque. Meanwhile, Infiniti will add the Q30 hatchback to its lineup by the end of the year, new president Roland Kruger reiterated in Detroit. It's expected to be joined by a crossover variant, and the additions will help strengthen Infiniti in the United States and abroad. "While we're expanding our product line, we're also expanding our market reach," he said. That's something echoed by Jaguar executives, who are preparing to launch the brand's first crossover, the F-Pace, in 2016.
