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 working on 600-hp F-Type SVR

Thinking about buying a new Jaguar F-Type? You've got a number of supercharged engine options to choose from... and soon you'll have one more. According to Motor Trend, Jaguar and its Special Vehicle Operations unit are working on a new SVR version of the F-Type, and it's tipped to pack 600 or more horsepower. That's more than anything Jaguar (or for that matter Land Rover) has offered for public consumption to date, but follows a delineated progression of output. As it is, the 5.0-liter supercharged V8 offered at launch in the F-Type convertible was already churning out 500 metric horsepower. Then came the F-Type R coupe that bumped output up to 550, followed by the limited-edition Project 7 roadster with 575. Topping 600 would only follow naturally, then, but would give the F-Type a broad range of outputs, starting at 335 hp and nearly doubling once it hits the top. It would also handsomely eclipse the Mercedes-AMG GT S (503 hp) and Porsche 911 Turbo S (552 hp), rival the Aston Martin Vantage GT12 (592 hp), and give even the new Audi R8 V10 Plus (610 hp) a run for its money. The bigger question is what form the SVR model will take, and with what other equipment. Coupe or convertible, rear-drive or all-wheel drive, automatic or manual... it's too early to say at this point. But we can probably expect much of the equipment from Project 7 – active diff, carbon-ceramic brakes... the works – to reappear in the SVR as well.

2017 Jaguar XE: We'll miss our long-termer, but not its diesel engine

This may be automotive journalist blasphemy, but diesels aren't always a good thing. And I don't mean that from an emissions standpoint. Sometimes the diesel in question isn't a good engine, and/or is a bad fit for the cars to which they're fitted. Our long-term Jaguar XE diesel is a textbook case of both issues. The first issue becomes apparent from the moment the 2.0-liter turbodiesel four-cylinder fires up with all the clattering, tapping and ticking that can only come from a compression-ignition engine. It's far from the shaking and knocking of full-size diesel trucks of a few decades ago, but it definitely feels a generation or two behind other diesel cars. For instance, we had a diesel Chevy Cruze in the office, which was quieter and smoother than the Jaguar despite a base price roughly $10,000 less. It becomes a bit smoother and less raucous as revs increase, but the volume remains rather high, making it sound as though the engine is struggling more than it is. Though, to Jaguar's credit, the company has managed to keep virtually all engine vibrations from entering the cabin. Now, the diesel engine's voice would be less problematic if it provided some engaging performance, but, outside of the high fuel-economy numbers, there's hardly any to be found. This may seem surprising considering the Jaguar's 318 pound-feet of torque, but that torque figure lasts only briefly from 1,750 rpm to 2,500 rpm. After that, the torque rapidly falls off, and you don't see the Jag's meager 180 horsepower peak until 4,000 rpm -- not far off of the engine's roughly 5,000-rpm redline. As a result, the XE has adequate passing power and around-town shunt, but anytime you want to play with more revs, it faceplants. But at least it does nail, and even exceed, its 40-mpg highway fuel economy rating without trying. The faults of this diesel engine are then exacerbated by the fact that it's in such a smooth and fun car as the XE. It positively glides across rough city streets and highways, keeping the chassis steady and its passengers soothed. Coupled with a quiet cabin, the XE is a peaceful place to be. At least it would be if the diesel didn't rudely interrupt every time the throttle pedal is pressed. Through some sort of black magic, the XE handles about as well as it rides. The incredibly sensitive and accurate steering is superb. It feels like adjustment knobs on a high-end stereo -- weighted perfectly and fine enough to get it right where you want it.
