Electric all-wheel drive. The ID.7 GTX and ID.7 GTX Tourer are equipped as standard with an electric 4MOTION all-wheel drive system. A separate electric drive motor in each case powers the front and rear axles. Together, both motors provide a system output of 250 kW (340 PS) – 40 kW (54 PS) more than the power of the rear-wheel drive ID.7 Pro and ID.7 Pro S models. With an output of 210 kW (286 PS), an APP550 permanent magnet synchronous motor (PSM) provides powerful propulsion at the rear axle. The PSM system is extremely efficient and makes its full performance potential available from a standing start. Depending on the power requirement and driving situation, the front electric motor is activated in fractions of a second. This is an asynchronous motor (ASM) with the designation AKA150. It produces a maximum output of 80 kW (109 PS). In standby mode, the ASM system hardly consumes any energy – a special feature of asynchronous motors that makes them ideal as an auxiliary drive. Power distribution is controlled by a modified all-wheel drive controller as well as by interventions by the electronic differential locks (XDS+). All this together leads to increased vehicle stability, improved load change reactions and ultimately to more driving pleasure. The holistic GTX dynamics have been extended to the limit range and the spread between the individual driving modes – from maximum comfort to maximum sportiness – has been increased. The electric 4MOTION all-wheel drive system enables good traction and offers neutral handling that is very easy to control. In addition, the maximum towing capacity (braked with eight per cent gradient) has been increased from 1,200 to 1,400 kg thanks to 4MOTION.
GTX punch and GTX efficiency. A special feature of the GTX drive is control of the power requirement: in contrast to a combustion engine, it is possible to vary the response characteristics almost infinitely with electric drive motors. In the ID. 7 GTX and ID.7 GTX Tourer, Volkswagen has developed a setup that converts the maximum system output and highest torque of the drive into propulsion within milliseconds at the start of an acceleration phase. In the world of combustion engines, only high-performance sports cars, if at all, can offer such immediate power delivery – the punch. Despite this dynamic performance, the ID.7 GTX models are also very efficient. Thanks to the new 86-kWh battery, the ID.7 GTX achieves a WLTP range of up to 595 km; in the case of the ID.7 GTX Tourer, the equivalent figure is up to 584 km. These values are made possible by WLTP consumptions of 18.4 to 16.2 kWh/100 km (saloon) and 18.8 to 16.6 kW/h/100 km (estate) respectively. Both GTX models are electronically limited to a top speed of 180 km/h.
86 kWh battery and 200 kW charging capacity. Both motors are powered by a new lithium-ion battery – Volkswagen’s largest to date, providing an energy content of 86 kWh (net); the gross energy content is 91 kWh. Compared to the 77-kWh battery of the ID.7 Pro models, the 86-kWh battery – which is also used in the new ID.7 Pro S models – is equipped with 13 instead of 12 cell modules. The battery system is integrated into the underbody. In detail, the battery assembly comprises the underbody guard, the all-round frame of the battery housing, a base plate with its own integrated cooling system, the battery modules, a battery management system, a cell management controller, the upper housing section and a network of lines and connectors. The new battery can be charged with up to 200 kW at DC quick-charging stations – the highest charging capacity was previously a maximum of 175 kW. Under ideal conditions, battery charging from 10 to 80 per cent is possible in only 26 minutes when charged with 200 kW.
Faster charging on the go. On journeys, an innovative charging and thermal management function makes sure the battery can be conditioned ahead of the next DC charging stop. Thanks to this electronic preparation, the ID.7 GTX models are supplied with energy again as quickly as possible on long journeys with one or more charging stops. The battery is heated to the ideal temperature before the charging stop 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 optional 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 also be manually activated using the charging menu in the infotainment system. Practical: 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. software automatically integrates the ideal charging stops into the route guidance of the navigation system – the driver does not have to search for the charging points first, but only has to follow the suggestions of the infotainment system.
