Lamborghini Murcielago LP640

6.5-liter (6.496 cm3) 60 V-engine and 640 bhp at 8,000 rpm is now used also in the Lamborghini Murcielago Roadster. At 6,000 rpm the 12-cylinder engine reaches the maximum torque of 487 lb-ft. The increased power naturally leads to increased road performance. The maximum speed now lies at 205 mph. The standard sprint from 0 to 62 mph is now reached by the Murcielago LP640 Roadster in an excellent 3.4 seconds making it 0.4 seconds faster than its forerunner. Higher performance and torque naturally mean increased demand on the drive components. A six-gear transmission adapted to these requirements, plus a stronger rear differential and new half-axles, have therefore been deployed in the new Murcielago Roadster. An e-gear transmission with a newly tuned thrust mode (acceleration program) is also available as an option. Like its forerunner, the new Murcielago Roadster LP640 has permanent four-wheel drive
