The new 911 Carrera (991) features a comprehensive thermal management system for the first time. The advantages achieved compared with the previous model are as significant as the possible operating states of the thermal management system are varied. Thermal management not only involves the engine, but also the transmission and heating.
Objective Networking of all relevant heat sources in order to • Reduce consumption by controlling the heat flows during all phases (up to 2%) • Reduce emission values • Reduce internal friction in the engine and transmission
