The 849 Testarossa Spider uses the PHEV architecture derived from the SF90 Spider and combines a V8 combustion engine and three electric motors with a total power of 163 kW (220 hp). Two of the electric units are located on the front axle and form the RAC-e system (Electronic Cornering Set-up Regulator), which ensures maximum traction and efficiency in corner exit through all-wheel drive and torque vectoring. The third electric motor, the MGU-K unit (Motor Generator Unit, Kinetic), is located on the rear axle and benefits greatly from the Scuderia's experience in Formula 1. The entire system has been further developed to improve performance and driving comfort. This includes optimized calibration to synchronize operation with the combustion engine. The control also integrates a new active damping function to regulate idle speed and improve the transition between thermal and electric operation. The cooling maps of the electric motors have also been optimized, now exhibiting a thermal efficiency 10 to 12 degrees Celsius higher. This ensures that the electric power remains constant even during intensive use over an extended period.
