The high-voltage battery, matched to the hybrid drive with NMC cells and with a capacity of 1.6 kWh (gross) usual for HEV vehicles, is integrated into the vehicle floor at the rear of both the Golf and the T-Roc. Three operating modes. Volkswagen has designed the interaction between the turbocharged petrol engine (1.5 TSI evo2), two electric motors and high-voltage battery to achieve a good balance of efficiency, dynamics and comfort. The electric motor responsible for the drive power replaces or supports the turbocharged petrol engine in all those phases in which it offers additional efficiency. For example, the Golf Hybrid and T-Roc Hybrid therefore often run on electric power alone, making them very quiet when moving off, at low speeds and thus in urban traffic.
