Lamborghini may have just dropped some info and specs on its latest special edition Gallardo, the LP 570-4 Spyder "Performante". I say "may have" because nearly 100% of the information in the press release posted by a forum member of Teamspeed is cut and pasted from the Superleggera's original info sheet (barring the weight / height / speed differences).
The Performante - if that is, indeed, its real name - benefits from a diet thanks to Lamborghini's now Lotus-like commitment to weight reduction, resulting in a Gallardo drop-top that's 143 lbs / 65 kg lighter than its predecessor.
