Lamborghini chief technical manager, Maurizio Reggiani, estimates that the hybrid system will add between 330 pounds to 440 pounds, even with various incorporated light solutions. Batteries and electric motors are just heavy. And because of this, Aventador's successor will have the extra weight of the hulk around. "I always say that I prefer to have 10kg less instead of 1hp even though the power-to-weight ratio remains the same," Reggiani said. "But I guess the starting point of the car will be heavier, no doubt. What will the playoff be? We don't know. Improvements will happen."
Another significant disadvantage of adapting this hybrid driver would be going to Nurburgring records. Weight is always the enemy. One potential solution Reggiani has in mind is, as Autocar describes it, to "share the hybrid system with an electrically powered front axle rather than a mixed array of electric power transmitted through a conventional transmission."
