The animation shows how the electric sound of the Audi e-tron GT works.
The electric all-wheel drive in the Q4 e-tron top models has an asynchronous motor (ASM) on the front wheels that can rev at up to 14,000 rpm. It is installed coaxially and has combined cooling with coolant and oil. The principal advantages of the ASM are its short-term overload capacity and the minimal drag losses when it is inactive – these are important because the front motor does not contribute to the drive in the majority of driving situations for reasons of efficiency.
The architecture of the modular electric drive system (MEB) on which the compact electric SUVs from Audi are based enables a completely new division of space. The technology components need only a little space: The high-voltage battery pack is designed as a flat block underneath the passenger compartment, while the drive unit is located in a compact arrangement on the rear axle – and on the front axle in the quattro models. The short front section houses the radiator, the electric brake booster and major components of the air-conditioning system.
Electric mobility is becoming dynamic and fascinating, as the Audi e-tron GT proves. The four-door coupé, which will be introduced in the market as an RS model at the same time, reinterprets the classic idea of the gran turismo: Its design is highly emotional, the technology revolutionary. Two powerful electric motors provide confident electric all-wheel drive and stunning road performance.
The e-tron GT quattro and the RS e-tron GT usually drive with electric all-wheel drive, only the “efficiency” mode of the Audi drive select dynamic handling system prioritizing the front-wheel drive. In event of a slippery road surface, high power requirements, or fast cornering, the electric motor for rear-wheel drive is also activated here, and around five times faster than with a mechanical quattro drivetrain. The electric all-wheel drive regulates the drive torque distribution between the axles – continuously, fully variably, and within a few thousandths of a second. The quattro principle of the four-wheel drive that Audi introduced to the market more than 40 years ago presents itself on a new, fascinating technological level. When the driver releases the right-hand pedal, the drive usually switches to sailing, allowing the gran turismo to glide with elegance and efficiency. By contrast, the car recuperates in overrun mode in the “dynamic” mode of Audi drive select.
