If the P12's unveiling is anything like the light show in the video, it should be a fantastic experience in Paris.

If you thought we didn’t need another Carrera version of the current 911, look away now – the Carrera GTS is revealed today, boasting a little bit more power, a millisecond or two of extra performance, a smidge more width, a smattering of cosmetic frippery and costing £12,500 more than a boggo model. If you happen to be Che Guevara or any other revolutionary, it isn’t for you. Let’s face it, this is a fairly blatant run-out job, with the next 911 due next year, but that doesn’t mean it won’t be brilliant to drive.
