This is the Jaguar XKR 75, a new, hotter, limited edition model built to celebrate the marque's 75th anniversary.
As the name implies, only 75 cars will be built, and they're suitably tuned - the 5.0-litre supercharged engine now has 523bhp and 483lb ft of torque. That means 0-60mph takes 4.4sec (down from 4.6sec), while it has a limited top speed of 174mph.
The handling and supsension has been returned to cope with the extra power and give the car an even sportier edge, while special kit such as a sports exhaust, side sill extensions and unique alloys add to the drama.
It also has a revised aero package, including a front splitter, rear wing and rear diffuser to ensure the car remains stable at high speed.
Jaguar says the modifications have not harmed the XKR's comfort.
The car will be officially unveiled at the the Goodwood Festival of Speed on 2 July.
