The F-Type has cemented itself as one of Jaguar’s greatest, most successful models in the automaker’s long history. From the new turbo-four model to my personal favorite, the SVR, the F-Type is a true sports car worth of attention. But Lister Motor Company saw some ways of improving the beast. It’s called the Lister Thunder, and it rumbles our a sinister 666 brake horsepower (660 in U.S. terms) and 719 pound-feet of torque thanks to upgrades made to the F-Type’s 5.0-liter supercharged V-8. The namesake feature, of course, is the upgraded exhaust system that, quite literally, sounds like thunder.
