Audi e-tron GT In Euromobil Glenmarie This Weekend
quattro reloaded, electric all-wheel drive e-tron supercar is here.
The e-tron GT is the first fully electric car from Audi to be built in Germany, and more specifically at the Audi Böllinger Höfe site in Neckarsulm. This Audi e-tron GT Electric Supercar pricing starts from RM559k.
The small-series production facility has been expanded and converted for its new role to enable the skilled craftsmanship characterising the original facility to be retained and supplemented with digital processes and smart technologies. During the expansion, production planners made use of new virtual methods.
The production for the e-tron GT was designed without any physical prototypes which is an innovation at Audi and this weekend you can get up close at the Audi Glenmarie showroom.

Battery and thermal management
The lithium-ion battery system at the heart of the Audi e-tron GT is located between the axles, at the car’s lowest point. This provides a low centre of gravity appropriate for a sports car and a weight distribution between the front and rear axles that is very close to the ideal value of 50:50.
The high-voltage battery can store 86 kWh of energy net (93 kWh gross) in both models. It integrates 33 cell modules, each comprising twelve pouch cells with flexible outer skin. 30 modules form the lower level that features a wide recess in the rear section which creates space for the rear passengers’ feet.
The upper “floor” of the battery contains three further modules situated below the rear seats. The connections, fuses, and the main control unit are located under the centre console. The system voltage of 800 volts enables a high continuous output and shortens the charging duration; in addition, it reduces the weight of, and space required by, the wiring.
The inner structure of the battery containing the modules, the frame surrounding it, and the cover plates are made of lightweight aluminium. The battery system contributes significantly to the rigidity and crash safety of the body to which it is attached via 28 screws. Beneath its cell space there is a compound structure of flat extruded sections through which coolant flows that circulates in its own low-temperature circuit.
High-tech thermal management: four separate coolant circuits
Four separate coolant circuits regulate the temperature in the high-voltage components and the interior, each at its own temperature level.
They can be interconnected flexibly when required. If the driver demands a high output several times in a row, valves couple the coolant circuit of the battery with the refrigerant circuit of the air conditioning system – the intensive cooling helps to maintain performance at a consistently high level.
The refrigerant circuit also helps with cooling during fast DC charging, which can heat the battery up to 50 degrees Celsius.
From 11 to 270 kW: AC and DC charging
Charging ports can be found behind both front wheels in the e-tron GT models. Both sides feature connections for alternating current (AC) and there is also a connection for direct current (DC) on the right-hand side.
Two charging cables are included as standard: one Type 2, Mode 3 for use at AC charging points including a home wallbox, and the compact e-tron charging system, consisting of a control unit and Type 2, Mode 2 cable with a domestic and industrial plug.
The intelligent charging system “connect” will also be available as an option, and enables both charging control via the myAudi app and function updates. In conjunction with a suitable home energy management system, it can also facilitate cost-optimised charging, activating the system when electricity is less expensive under a variable electricity rate.
The e-tron GT can charge with up to 11 kW AC as standard, meaning an empty battery can be replenished overnight. An optional onboard charger which increases charging capability to up to 22 kW will be available shortly after launch.
At a sufficiently powerful DC terminal, the electric coupé can achieve a peak charging capacity of up to 270 kW, allowing it to take on board enough charge for a journey of up to 62 miles in just over five minutes. Charging from 5 to 80 percent SoC (state of charge) takes less than 23 minutes in ideal conditions.
