Audi S4 Sedan TDI 48 Volt MHEV Animation
  • 5 years ago
The electric powered compressor is integrated into a new 48-volt main electrical system, which also incorporates the mild-hybrid system. This provides even more efficiency potential than the MHEV system in the 12-volt electrical system on the A4 models. In the S4 TDI this is the next expansion stage in which the mild-hybrid technology will be rolled out based on 48 volts.
