- A 155 kW 2.0 TFSI petrol engine combines with a 33 kW electric motor and an 8-speed tiptronic
transmission.
Audi used the 2011 Detroit Motor Show to reveal the all-new A6 hybrid, which will be released in
Europe this year. It's the brand's second hybrid model as it follows the Q5 hybrid quattro.
The A6 hybrid has an efficient parallel hybrid concept: its combustion engine, a 155 kW 2.0
TFSI, works together with an electric motor that delivers 33 kW and 211 Nm of torque. The electric
motor sits directly behind the TFSI, occupying the space of the torque converter upstream of the
modified 8-speed tiptronic transmission. This transmission sends torque to the front wheels.
A crash-protected area of the luggage compartment houses a light, compact lithium-ion battery
that provides 1.3 kWh of nominal power and generates 39 kW.
Depending on requirements, it is air-cooled in two ways – by means of a blower from the interior
or via an internal refrigerant circuit coupled to the automatic air conditioning system. This
technology largely maintains the rechargeable battery within the appropriate temperature range,
thereby ensuring that the vehicle operates on electric power a comparatively large percentage of
the time.

The Audi A6 hybrid can achieve speeds of up to 100 km/h purely on electricity; at a constant
speed of 60 km/h, it has a range of 3 km. It can also operate with the combustion engine only or
in hybrid mode; in the deceleration phases, it recovers power and activates both the engine and
the electric motor together when accelerating quickly. Special indicators on the instrument
cluster and on the MMI monitor provide a detailed display of the different driving conditions.
The Audi A6 hybrid provides the power of a V6, combined with the fuel efficiency of a
four-cylinder engine. It accelerates from zero to 100 km/h in 7.3 seconds, top speed is 238 km/h,
the average fuel consumption is 6.2 litres per 100 km (European figures), and its CO2 emissions
are just 142 grammes per km (performance and fuel consumption figures are provisional).
There are no plans for a right-hand drive version of the Audi A6 Hybrid as the model is intended
for sales in western Europe, North America, Japan and China only.
Audi's next hybrid model is to be a version of the new A8. It is likely to arrive next year.
