Jaguar has unleashed its 'most potent series production car ever', the XKR-S.
It gets a 550hp version of the 5.0-litre supercharged V8 engine from the standard car - a 32hp power swell.
It means a 0-100km/h sprint in 4.2 seconds, and a quite astonishing 8.6-second run to 160km/h. It has a 300km/h top speed.
It's also relatively clean, with Jaguar claiming it's the only car in its class to put out less than 300g/km of CO2. That's still in Band G mind you.
Jaguar gives little away in terms of what's been done to make the car so quick, but does say it has an "aerodynamically driven design," and is "not merely the quickest Jaguar ever, but the most agile, responsive and driver focussed."
No prices as yet.
The company will also kick off its 50th birthday celebrations for the E-Type in Geneva, hosting drives of the car at the Parc des Eaux Vives.
