Lamborghini Murcielago LP650-4 Roadster

Lamborghini Murcielago LP650-4 Roadster Expected to sport the same 650bhp engine as the Reventon, this LP650-4 looks like it’s going to be one of the quickest open-topped cars there is, with a 0-60 time just over 3 seconds. Just like the Reventon, the LP650-4 looks likely to come in just one colour choice, in this case a matt grey (Grigio Telesta) with orange accents, and dark painted alloys.
