Jaguar revealed their Goodwood special edition XKR yesterday at the annual Festival of Speed. The limited edition pussy-cat gets an extra 20 horses under the bonnet, bringing this envious-looking little kitty up to 530 HP.

The one-off performance model features a lowered suspension and a tweaked exhaust system for a louder and more intimidating sound and was purposely built for the event, painted in an extremely distinct lime-green color while the coupe also featured special exterior graphics in gray and orange.

Other styling tweaks that differentiate this model over the standard 2010 XKR facelift include the 21-inch alloys and the satin graphite detailing to the front grilles, door mirrors, rear signature blade, side window surrounds, headlights and bonnet louvres.

What's more is Jaguar's engineers fiddled around with the XKR's supercharged 5.0-liter V8 that in standard form makes 510 HP and 461 lb-ft of torque launching the sports coupe from 0-to-60 MPH in 4.6 seconds. In the XKR Goodwood Special, output is lifted to 530 HP and torque to 516.2 lb-ft. No word on what that'll do to the final 0-to-60 time. Gallery below.
