2014 Jaguar XJL AWD 3.0

A bit of British nobility floods the senses when piloting the 2014 Jaguar XJ. It's an emotional rush, a perception based on physical surroundings that influence the mind in much the same manner that a stein of pilsner tastes best when consumed in a German beer garden and no sand is softer than that found on a warm Caribbean beach. Jaguar has been assembling cars for nearly 100 years, and few automakers are as equally adept at capturing aristocracy and timelessness within the rich cabins of their luxury offerings.
Jaguar would have no concern if it were the only game in town, but that's far from the truth. The premium full-size luxury segment, which includes vehicles hovering just under or at the six-figure mark, is a contentious grouping that includes the Audi A8, BMW 7 Series, Lexus LS, Mercedes-Benz S-Class and Porsche Panamera. Each of those brings its own game to the battle, and none are easy to dismiss.
To better understand the British perspective and evaluate its latest offering on a land without royalty, I recently spent a week with a long-wheelbase, all-wheel-drive Jaguar XJ in Southern California.

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.

This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.
