Summary

The Q7 e-tron quattro sees Audi present its first plug-in hybrid vehicle with a TDI engine and quattro powertrain. Following the successful introduction of the Audi Q5 hybrid quattro, A6 hybrid and A8 hybrid models, and the A3 e-tron with plug-in technology, this is the Audi e-tron family's first premium SUV, based on the second generation of the modular longitudinal matrix. The compact drivetrain integrates a hybrid module with a high-torque electric machine between the internal combustion engine and the automatic transmission torque converter. This means impressive performance with best-in-class consumption figures. The TDI engine was optimised for the specific requirements in a plug-in hybrid vehicle, including intelligent thermal management. New developments in the Audi Q7 e-tron quattro drivetrain also include the hybrid module with its highly efficient electric machine, the matching power electronics, which also supply the electrical system, and the powerful lithium-ion battery with on-board charger.
