The study of an open-top sports car demonstrates the potential of the plug-in
hybrid drive. A twin-turbo V6 TDI produces 221 kW (300 hp); the two electric
motors together deliver an additional 64 kW (87 hp) of power.
The A1 e-tron is
an innovative
Mega City Vehicle
(MCV) with
electric drive and
a single-rotor
engine with

study’s total
range is up to
250 kilometers.

A1 e-tron
to be done is to “build on the Audi
core competences” on this basis.
quattro permanent all-wheel
drive has been a part of this for
over 30 years. Electric cars off er
entirely new possibilities in this
fi eld. The four electric motors fi tted
on the Audi e-tron can be individu-
ally controlled – a type of quattro
drive for electric cars. The four
motors allow what is known as
torque vectoring, the selective accel-
eration of individual wheels and
therefore active distribution of torque.
“The Audi e-tron,” says Dr. Michael
Korte, Head of Predevelopment of
Vehicle Concepts at Audi, “is superior
to the majority of conventional cars at
the limit.”
