The new Audi Q8 e-tron - Revised rear axle motor and electric torque vectoring for more dynamics

The motor concept of the asynchronous machines on the rear axle has been modified for the new Audi Q8 e-tron. Instead of twelve, 14 windings now generate the electric magnetic field. With the same current input, the motor thus generates a stronger magnetic field, which in turn ensures higher engine torque. If this is not called up, the electric motor requires less current to build up torque. This reduces consumption and increases the range. With the S model of the e-tron series, Audi has realized a three-motor concept for the first time in large-scale production. This has now been further developed in the new SQ8 e-tron. A 124 kW e-machine operates on the front axle. At the rear axle there are two electric motors with an output of 98 kW each, which separately drive one rear wheel each. This results in a boost power of up to 370 kW. The drive torque can be completely distributed between the two wheels in a fraction of a second via the two rear electric motors.
