Adds an inordinate amount of power.
As with every other car that’s passed through its Texas garage, Hennessey has taken a look at the most British of British muscle cars – the Jaguar F-Type – and decided it doesn’t have enough power. We would have thought the 542 hp and 502 lb-ft of torque being pumped out by the 5.0-liter V8 would have been enough for most, but Hennessey has gone and boosted it to a whopping 623 hp and 568 lb-ft. The result is a new 0-60 mph time of 3.5 seconds, over half-a-second less than the stock F-Type R, and a quarter-mile time of 11.4 seconds @ 126 mph.
