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.

Jaguar Project 7 Concept

The Jaguar Project 7 Concept debuted at the Goodwood Festival of Speed just last month. But unlike most concepts, which serve only to collect fingerprints on a stage, the track-ready one-seater spent its days barreling past the hillclimb crowds with Mike Cross, chief engineer of vehicle integrity at Jaguar, beaming behind its right-hand-drive steering wheel. What's more, the powers that be at Jaguar even let yours truly drive the Project 7 during the Concurs d'Elegance festivities at Pebble Beach last week.
Built on an all-aluminum V8 F-Type chassis with modified suspension, the Project 7 (a name acknowledging Jaguar's seven Le Mans wins between 1951-1990) is best thought of as an F-Type masquerading as a D-Type. The two-door is fitted with a supercharged 5.0-liter V8 good for 550 horsepower (no pictures as Jaguar wouldn't allow us to open the hood). An eight-speed automatic, with a torque converter, sends the power the rear wheels, allowing the single-seat roadster to crack the 60-mph benchmark in just over four seconds.
Modifications to the bodywork include a new lowered windshield, carbon-fiber aerodynamics and a rear fairing with integrated rollover hoop. The driving position has also been lowered by more than an inch, allowing the sole occupant to not only escape the airflow, but take advantage of a lower center of gravity.

Jaguar Activity Key | 2017 Autoblog Technology of the Year Finalist

In principle, the Jaguar Activity Key is a good idea. It's simple, useful, and relatively inexpensive. Unfortunately, in our testing it was less than reliable. Here's how it's supposed to work: To lock the car, leave your keys and fobs inside the vehicle, and strap the band on your wrist. Then, within 30 seconds, place your banded wrist against the letter J of the Jaguar script on the back tailgate. When you come back, you can unlock the vehicle by pressing the tailgate opening button, then, again within 30 seconds, placing the Activity Key band against the J of the Jaguar script. We chose the Jaguar Activity Key as a finalist for our 2017 Tech of the Year award because it's an uncomplicated device with lots of potential customers. Jaguar says the wristband is "robust and fully waterproof." Swimmers, surfers, kayakers, hikers, and even couples out for a sunny-day picnic could use a feature like this wristband key. Plus, wearables are pretty new as a category in general, and even more so in the automotive space. We didn't go skydiving with it or anything (an activity Jaguar cites as a potential usage case), but we did dunk it in water with no ill effects. While it all sounds good in theory, actually getting the Activity Key to work effectively was unexpectedly difficult, especially when the cameras were rolling. We tried varying the timing between closing the door and using the wristband, as well as between using the tailgate button and the wristband. It worked about half the time, regardless of our process or who was wearing the wristband. Whether our issues with the wristband were due to interference, new-technology teething problems, or just electrical gremlins, the idea of purposely locking the keys inside an automobile without having a foolproof way to unlock it gives us reason to pause. The Activity Key is a $400 standalone option on the 2017 Jaguar F-Pace, but only on Prestige, R-Sport and S models. The least expensive F-Pace with Activity Key costs $51,095.
