Efficiency
At Audi, doing less is something we’re trying to do
more of. We’re working to use less fuel, release
less CO
2 and waste less energy. It’s why we’ve
incorporated a number of more efficient technologies
into the Audi A6 Saloon.
Recuperation
When a vehicle brakes, the discs convert the kinetic
energy into thermal energy, which is wasted as it
cannot be used. With a recuperation system, like
the one in the Audi A6 Saloon, the kinetic energy is
converted into useful electrical energy. The way it
works is simple. While the car is coasting or braking,
the alternator voltage is raised above the level of the
basic electrical system, which enables the alternator
to generate electrical energy and store it temporarily
in the battery. When the vehicle accelerates, this
energy is used to relieve the load on the alternator,
resulting in a fuel saving of up to 3%.
Enhanced air conditioning
The efficient cooling system in the Audi A6 can
save up to 8 g/km of CO
2 compared with the previous
model. It’s thanks to a new brushless motor that’s
lighter, uses less energy and has a longer
operating life.
