WOLFSBURG: For the first time at Volkswagen, the Golf and T-Roc are available as full hybrids.
Volkswagen has developed a new full hybrid drive system for the Golf and the T-Roc.
The efficient drive system is called ‘Hybrid’ and is now making its global debut appearance in the two compact bestsellers.
The new drive system comprises the integration of two electric motors and a turbocharged petrol engine (TSI) in one unit.
The hybrid drive does not require an external charging interface and still enables all-electric driving up to 60kph.
Its efficiency is clearly reflected in WLTP consumption values of as low as 5.6 litres, coasting with the TSI switched off and long combined WLTP ranges of more than 800kms.
In addition, the new drive system offers excellent performance when moving off and exceptional low-end torque during acceleration, as the electric drive motor supports the four-cylinder turbocharged petrol engine like an electric booster.
The Golf Hybrid and the T-Roc Hybrid are available with a system power of 100kW (136PS) and 125kW (170PS).
Sales of both models have already started in many European countries.
Depending on the situation, the energy for the electric drive of the Golf Hybrid and the T-Roc Hybrid is generated by recuperation or additionally by the second electric motor working as a generator.
In this case, the generator is driven by the TSI engine.
The turbocharged petrol engine then temporarily takes over the function of a range extender.
Above around 60kph, the new hybrid models are powered by the TSI alone or by a combination of the petrol engine and electric motor.
The turbocharged petrol engine also switches on as soon as the driver dynamically requests a high output – for example, by using the kickdown function when overtaking.
At speeds of up to 60kph, the Golf Hybrid and T-Roc Hybrid are powered by the electric motor alone as often as possible.
In this case, the 1.5-litre turbocharged petrol engine is switched off.
The turbocharged petrol engine is active as the primary drive system from 60kph on country roads and motorways.
The electric drive motor supports the turbocharged engine as required, for example, as a booster when accelerating.
Depending on the operating window of the TSI, energy is also generated here via the generator motor for charging the battery.
