Audi E-Tron tweaks unlock more range

Audi has used a number of small tweaks to free up 25km of extra range from its electric E-Tron SUV. The changes were debuted on the E-Tron Sportback revealed at the Los Angeles motor show, but have been passed on to the more practical E-Tron. According to Audi, the regenerative braking system – which uses the electric motors to harvest energy usually lost to heat when you brake – has been reworked to reduce residual brake torque, created by the brake calipers sitting close to the discs.
