GTX power. The newly developed Volkswagen APP550 high-efficiency drive is used in the ID.3 GTX. The special feature for the ID.3 GTX is that the drive motor is not only offered with an output of 210 kW, but also with 240 kW for the first time. The electric drive motor produces a maximum torque of 545 Nm for both output ratings – thus even exceeding the drive power of the most powerful Volkswagen V6 turbocharged engines. The motors accelerate the ID.3 GTX to 100 km/h in just 5.9 seconds and in up to 5.7 seconds for the ID.3 GTX Performance. A fascinating feature of both GTX versions is control of the power requirement. In contrast to a combustion engine, it is possible to vary the response characteristics almost infinitely with an electric drive motor. In the ID.3 GTX and ID.3 GTX Performance, an extremely sporty configuration was developed that immediately converts the maximum system output and the highest torque of the drive into propulsion within milliseconds at the start of an acceleration phase – creating a noticeable punch. Volkswagen has also modified the top speed of both models thanks to the increased power and efficiency of the electric drive motors. Instead of 160 km/h as for the familiar models in the model series, the ID.3 GTX is electronically limited to 180 km/h (111 mph) and the ID.3 GTX Performance to 200 km/h (124 mph). The GTX drive motors are powered by a new lithium-ion battery with a net energy content of 79 kWh (gross: 84 kWh).
GTX drive. The APP550 electric drive powers the rear axle and essentially consists of the following modules: a permanent magnet synchronous motor, the two-stage one-speed gearbox and the inverter (power and control electronics). In contrast to the less powerful versions of the product line, the increased power and efficiency of the GTX motors are the result of details such as a rotor with strong permanent magnets that offer a high thermal load capacity, a further-developed stator with a large effective number of windings in combination with maximum wire cross-section, a water heat sink for the outside of the stator, and a combined oil and water cooling system that ensures high thermal stability. The thermal stability is safeguarded by a new inverter generation, and the high thermal load capacity is an elementary contributing factor to the increased efficiency of the new drive. Numerous gearbox components have also been friction-optimised and reinforced, and thus adapted to the high power and torque values. In conjunction with the 79-kWh battery, the combined WLTP range of the ID.3 GTX is up to 604 km.
Faster charging on the go. On journeys, a new and innovative charging and thermal management function makes sure the battery is pre-conditioned ahead of the next DC charging stop. Thanks to this pre-conditioning, the ID.3 GTX and ID.3 GTX Performance are supplied with new energy again as quickly as possible on long journeys with one or more charging stops. The battery is heated to the optimum temperature before the car stops so it can be charged at maximum power. This enables the charging time to be reduced by several minutes, particularly in winter. When route guidance by the navigation system with the Electric Vehicle Route Planner is active, pre-conditioning is started automatically on the way to the next quick-charging station. Without active route guidance, the function can be activated manually using the charging menu in the infotainment system. Routes with up to 10 charging stops and 10 stopovers can be planned on a smartphone or on the web portal and then transferred to the infotainment system.
