Audi e-tron

The Audi
e-tron concept is effectively an electric quattro, and its incredible 4,500 Nm
of torque helps it to accelerate from 60 to 120 km/h in just 4.1 seconds.

The e-tron
‘test platform’ on display at Frankfurt has four motors, two at the front and
two at the rear axles, which are installed behind the wheels as wheel drives.
Under normal conditions, 70 percent of the power goes to the rear and 30
percent to the front, but it can distribute the torque of its four electric
motors to the wheels as required.

lithium-ion battery, positioned directly behind the passenger cabin, provides a
range of around 154 miles, and top speed is limited to 124 mph.

two-seater has lightweight construction, but thanks to the batteries and four
motors it still weighs in at 1,600 kg.

It also has
active aerodynamics – air intakes in the grille and in front of the rear wheel
wells that are closed flush under normal circumstances and opened by means of
flaps when additional cooling air is required.

With the
battery fully discharged, the charging time is between 6 and 8 hours. A high
voltage reduces this to just around 2.5 hours.

Engineers are
working on a wireless charging solution – an inductive charging station, which
can be used in a home garage at home or in special parking garages, and which
is activated automatically when the vehicle is docked. Such technology is
already used today in a similar form to charge electric toothbrushes.
