When comes to horsepower, some car enthusiasts can be quite an insatiable bunch, like what else can ask for when you already have 550 hp ride that makes, on paper, 0-60 in 4 seconds? Sure, it won’t be the fastest, but it is very fast, even more so if it is a daily ride like the the Jaguar F-Type Coupe or the R. However, if you are ever so inclined towards having more ponies out of a 2014-25 Jaguar F-Type Coupe and R, which by itself already has a very healthy 550 hp squeezed out of its 5.0-liter V8 Supercharged unit, John Hennessy may have the answer you’re looking for. For years, Hennessy has been helping American muscles to realize more power in exchange for a tidy sum, but now, he wants to push the performance boundaries of the British big cat further with the HPE600 Upgrade Kit that is said to yield 623 hp at the crank with 568 lb-ft of torque on the tap.
The result is a beastly feline that pulls 0-60 in mere 3.5 seconds, taking a good half a second off the stock F-Type Coupe R, and a quarter mile dash done in just 11.4 seconds at a trap speed of 126 mph. If you’re into performance cars of any kind, there is little left to explain how quick that is and if you are not, all you need to know is this: it’s freaking fast. On top of that, you get all the luxury the British marque has to offer, along with some subtle reminder of where this new found power comes from – by the way of a dash plague and a engine plague with a unique Hennessy serial number and some exterior badging, just so that everyone else knows this ain’t your typical F-Type-next-door. Hennessey HPE600 Upgrade Kit is available to suit all 2014-25 Jaguar F-Type models fitted with 5.0-liter supercharged V8 motor. Though pricing is unknown at this point.
