Lamborghini describes its new Murciélago LP670-4 SuperVeloce (SV) as being "exceptionally purist and even more extreme" than its siblings, with added power, less weight, and greater speed potential. The LP670-4 will be built as a limited edition of 350 units.
Its 6.5-L V12 engine produces 493 kW (661 hp) at 8000 rpm and 660 N·m (487 lb·ft) at 6500 rpm, and with mass reduced by 100 kg (220 lb), the car's mass/power ratio is now 2.3 kg/hp. Top speed is "around" 342 km/h (213 mph), stated Lamborghini at the Geneva Motor Show where the all-wheel-drive car was revealed. Zero to 100 km/h (62 mph) takes 3.2 s.
The added power for the longitudinally mounted V12 has been achieved via a modified intake system and optimized valvetrain with increased valve travel.
The exhaust system is entirely new and is a major contribution to a mass reduction in the engine area of 26 kg (57 lb). It uses lighter weight materials and has a redesigned muffler. The system’s acoustics generation was given a non-technical but interesting description by Lamborghini at Geneva: "From the heavy rumble of a stormy night, through the trumpeting of mighty elephants, to the roar of a raging lion, the SuperVeloce performs the grand opera for 12 cylinders, 48 valves, and 8000 revs!"
On a rather less theatrical level, Lamborghini lists mass reduction of the SV as 33 kg (73 lb) for the chassis and exterior, 34 kg (75 lb) for the interior, and a total of 33 kg from the combination of engine and drivetrain. The extended use of high-strength steel not only saved 20 kg (44 lb) but also upped torsional stiffness by some 12%. A fixed instead of powered deployable spoiler saved 13 kg (29 lb). There is a choice of spoiler size.
Interior trim is mainly carbon fiber (including the bucket seats) and Alcantara, which is also used for the roof lining. It is lighter than leather. Bentley, like Lamborghini a member of the Volkswagen Group, also uses the material for its new Continental Supersports, which has similarly been the subject of a weight-saving program. An in-car entertainment/navigation system is not standard the LP670-4, again to save weight, but it is available as an option.
