Audi has continued to drip-feed technical information about its upcoming E-tron electric SUV by stating that it will be capable of at least 248 miles on each charge and of smart charging to ensure efficient management of energy.

The car, which is due to be fully revealed in August, will be powered by a dual-motor powertrain using a 95kWh lithium ion battery and capable of 150kWh DC fast-charging. The latter is claimed as a world first and is 30kW more rapid than Tesla's Supercharger network.

Also confirmed is the use of alternating current AC chargers that can top up the battery by recovering energy on the move. As standard, the car will feature 11kW chargers for this, although 22kW chargers will be available as an option to enhance the recovery rate.
