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 allroad.
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 allroad, 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 3%.
TDI and FSI
Inside the engine of the Audi A6 allroad you’ll find
the same advanced fuel-injection technology that’s
driven us to eight Le Mans victories in the last ten
years. With TDI and FSI, fuel is injected directly
into the engine’s chambers so that combustion is
timed right down to the millisecond. As a result,
waste is minimised and you get the most from
every last drop of fuel.
