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.

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.

Jay Leno's Garage features funnyman's 1963 Jaguar E-Type

Jay Leno looks inward on this episode of his eponymous garage, checking out a 1963 Jaguar XKE that he bought earlier this year. It is an example of his favorite kind of car, that being original and unrestored. He bought the E-Type from its first owner, a woman who purchased it new, held on to it for 50 years and took excellent care of it. Having never been in an accident, Leno says even the paint is 85- to 90-percent original.
In the video, the XKE sits in front of two heavily modded XK120s and another '63 XKE, but Leno said all he's done - and all he plans to do - is clean it up and put on a modern set of wire wheels for safety.
He's not on any junket and there are no guests, it's just a guy talking about an object dear to his heart. If you need a refresher on the excellent genes of the new F-Type, check out the video below.
