The Murciélago LP670-4 SuperVeloce (SV: two letters formerly used by the Miura, Countach and other Diablo models) has not only undergone weight training, it has also gone on a diet to lose 100 kg. Farewell to the retractable spoiler: it has been replaced by a lighter, fixed element. A huge carbon wing is even available as an option. Carbon: that’s the word. Carbon is used generously in the cabin, the structure and the bodywork. But the Sant’Agata firm also insists on a lightened exhaust system, which would ensure an even greater ‘acoustic experience’, from 0 to over 8,000 rpm. So it was possible? While the ears are in for a treat, the other senses will also be alerted, because the performance is inevitably from another planet. Carbon ceramic brakes and the six-speed E-Gear robotised gearbox come as standard, and can be replaced by a manual gearbox. But the main dilemma lies elsewhere: between this extreme Lamborghini and the Murciélago Roadster LP650-4 , only slightly less radical and also presented at Geneva, how do you choose?
