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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

1964 Jaguar XKE slinks into Jay Leno's Garage

The idea of altering a classic Jaguar E-Type might seem preposterous to some, but Jasen Len of XKs Unlimited managed to create a modified 1964 E-Type that stays true to the Jag's timeless design. Just a few months after Jay Leno featured his own original E-Type on Jay Leno's Garage, Len stopped by to show off his custom Jaguar creation.
Starting out with a rust-ravaged body, Len made the car just the way he wanted it to be. He started off with some minor changes to the car's exterior like the Le Mans-inspired racing lights and handmade front bumpers, handmade sills with integrated exhaust and flared rear fenders. Inside, he dropped the floor to make more interior space and reworked the E-Type's styling for more of a modern look. We have to say, if you're going to mess with a Series 1 E-Type, this is the way to do it.
Sadly, even though Len and Leno spend plenty of time talking about the car's 300-horsepower 3.8-liter inline six-cylinder, we never get to hear the car fire up. Check out the JLG video, which is posted below, and as a bonus, enjoy the gallery from Jaguar showing a 1961 E-Type.
