Lamborghini Aventador S On Snow and Ice – Video
The Lamborghini Aventador’s naturally aspirated twelve cylinder, 6.5 liter engine outputs an additional 40 hp over its predecessor, to a maximum 740 hp, with a 690 Nm of torque at 5,500 rpm. To achieve the power increase, both VVT (Variable Valve Timing) and VIS (Variable Intake System) have been optimized in order to obtain an enriched torque curve. Additionally, the maximum engine revs have been increased from 8,350 to 8,500 rpm. A dry weight of just 1,575 kg provides a weight-to-power ratio of just 2.13 kg/hp. Acceleration from 0-100 km/h is reached in 2.9 seconds, with a top speed of 350 km/h. Transmission is provided by Lamborghini’s lightweight Independent Shifting Rod (ISR) 7-speed shifting system, providing robotized gear shifts in up to 50 milliseconds.
The Aventador S adopts a new exhaust system developed as the result of a significant R&D project. More than 20% lighter than its predecessor and the product of testing multiple configurations, the results are an enhanced Lamborghini sound and resonance from the already inimitable V12 aspirated engine, with the three single pipe outlets at the rear of the Aventador S a visual reminder of the new exhaust system.
As in its predecessor, the Aventador S is equipped with a stop-and-start system and cylinder deactivation for optimized engine efficiency. When full engine capacity is not required, six of the twelve cylinders are temporarily deactivated by switching off one cylinder bank. When the driver accelerates, the system switches back instantaneously to twelve-cylinder mode, with the changeover virtually impossible to detect by the driver.
