Following the reveal of the Audi A8 Hybrid at the 2010
Geneva Motor Show, Audi is preparing for the European release of their Hybrid models. Audi intends to
bring two hybrid models to market in the near future. The first will be the Q5 Hybrid quattro during
the first half of 2011, followed sometime later by the A6 Hybrid. The A8 Hybrid itself remains a
distance probability, most likely available for a 2012 release.
The A6 hybrid employs an efficient parallel hybrid concept: Its combustion engine, a 155 kW (211
hp) 2.0 TFSI, works together with an electric motor that delivers 33 kW (45 hp) and 211 Nm (155.63
lb-ft) of torque. The electric motor sits directly behind the TFSI, occupying the space of the
torque converter upstream of the modified 8-speed tiptronic. The 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 by means of 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 (62.14 mph) purely on electricity; at a
constant speed of 60 km/h (37.28 mph), 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 of 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 in 7.3 seconds from zero to 100 km/h (62.14 mph), top speed is
238 km/h (147.89 mph) and the average fuel consumption is 6.2 litres per 100 km, a CO2 emissions
level of 142 grammes per km (performance and fuel consumption figures are provisional).
