With driving dynamics tests on Namibia’s salt flats and savanna, the Audi e-tron prototype is at present impressively demonstrating its handling qualities. All made possible thanks to a new generation of the quattro drive – the electric all-wheel drive. In conjunction with the versatile suspension, its low center of gravity and the powerful electric motors, the electric SUV offers powerful traction, outstanding dynamics and unshakable stability on disparate terrain.The scenario: drifting across the sand flats and offroad through the savannaThe dried-out salt lake on the edge of the Kalahari Desert measures 2 by 2.3 kilometers (1.2 by 1.4 mi). Its porous, hard surface with fine-grained gravel offers a low coefficient of friction – optimal conditions to experience the Audi e-tron prototype in a controlled drift and get a feel for its lightning-fast acceleration coupled with high traction. This is possible thanks to the electric all-wheel drive and numerous suspension systems that are intelligently interconnected, most notably the Electronic Stabilization Control (ESC), the Audi drive select dynamic handling system and the standard air suspension. On rough terrain it increases the ground clearance of the Audi e-tron prototype at the push of a button by 50 millimeters (2.0 in). At the same time the ESC optimizes the traction and brake control and increases the effect of the electronic differential lock for optimum power transfer and propulsive power. As such, the electric SUV effortlessly takes even the sandy soil of the African savanna in its stride. The two electric motors provide the ideal power source for the high-precision, ultrafast electric quattro. In boost mode they provide up to 300 kW and a maximum 664 Nm (489.7 lb-ft) of torque. The effective thermal management plays a crucial role in their performance. It allows the performance to be reproduced even if the powertrain components are subjected to high loads. The result: outstanding dynamic handling and driving pleasure at all times.

The Audi e-tron prototype combines enormous power and high efficiency. With a system output of up to 300 kW, the full-size SUV with a fully electric drive accelerates from zero to 100 km/h (62.1 mph) in less than six seconds. In the WLTP test cycle, it covers more than 400 kilometers (248.5 mi) on one battery charge. One important factor for the long range is the most innovative recuperation concept among the competitors. The electric SUV proved this with an impressive performance at Pikes Peak.
At 4,301 meters Pikes Peak looms high in the southern Rocky Mountains. The best place to test the unique and most innovative recuperation concept of the Audi e-tron prototype. The scenario: each kilometer downhill brings around an additional kilometer in range. So on its 31 kilometer downhill drive the electric SUV feeds so much energy back to the battery that it can cover approximately the same distance again. Unrivalled!
In late January, Audi sent its first fully electric-powered SUV onto the slopes where the world’s best ski racers battle for victory in the Hahnenkamm Race. The specially equipped Audi e‑tron climbed the “Mausefalle” on the legendary “Streif”. With an 85 percent gradient, it is the steepest section of the spectacular downhill course. With an 85 percent gradient, the “Mausefalle” is the steepest section of the famous “Streif” downhill course in Kitzbühel. To climb this passage, the Audi e‑tron technology demonstrator was equipped with a special quattro powertrain with two electric motors on the rear axle and one electric motor on the front axle. The technology demonstrator achieved a total boost output of up to 370 kW and wheel torque of 8,920 Nm (6,579.1 lb-ft). This ensured full performance on the steep gradient. Audi also modified the software with respect to drive torque and torque distribution for the special conditions on the “Streif”. 19-inch wheels with spikes developed specifically for this driving event provided the necessary grip on snow and ice.
