Electric All Wheel Drive System Quattro on Audi E-Tron Models

The quattro all-wheel drive system, which celebrates Audi's 40th anniversary this year and is described as a revolution in the automotive world, has been updated and perfected over the years. Now, the electric quattro technology in e-tron models carries this system to the electromobility age.

Audi made a breakthrough in automotive history with its quattro permanent all-wheel drive system in 1980, when no automaker had yet developed a fast, lightweight and mass-produced four-wheel drive system. Quattro, meaning 4 in Latin, is based on the principle of transferring the engine's power to the front and rear axle at varying rates according to road conditions.

If we try to explain it in the most basic way, the quattro system activates all four wheels continuously and without interruption. It transfers the most accurate traction force to each wheel, depending on the ground conditions that each wheel of the vehicle touches. The quattro all-wheel drive system distributes the drive force between the four wheels. This ensures optimum force distribution between the wheels and the vehicle maintains its grip even under extreme conditions such as cornering or wet, snowy or ice. Audi currently offers this system in over 100 models of traditional combustion and hybrid models.

The quattro of the future

The brand has recently perfected this system for the electric car family e-tron, bringing together high performance, unique handling, safety and energy efficiency in a single point.

Audi's current e-tron models have two electric motors on the front and rear axle. Under normal conditions, the vehicle moves by electric motors on the rear axle. Thus, while saving energy, a smooth and comfortable ride is provided. Electric motors on the front axle only come into play when a more dynamic drive is required, high torque is required, or when handling is difficult, such as slippery, wet or snowy ground.

In the e-tron S models, there are two electric motors on the rear axle as well as an electric motor on the front axle. Thus, the e-quattro system can work more agile in S models. In both versions, Audi engineering technology comes into play in the distribution of power to the wheels. Unlike the traditional quattro system, this distribution is achieved by an advanced and sophisticated software system, since mechanical connections are not used in the distribution of power.
