Default Here comes the 2012 Audi A8 HYBRID

From Audi
Consistently efficient – the Audi A8 hybrid

The luxury sedan with hybrid drive is on its way in 2012
245 hp system output, fuel consumption under 6.4 liters per 100 km
Four-cylinder gasoline engine, powerful electric motor and lithium-ion
battery

The power of a six-cylinder model, the fuel consumption of a
four-cylinder version: Audi will be starting series production of the
A8 hybrid in 2012. Its gasoline engine – a 2.0 TFSI – and an electric
motor develop peak output of 180 kW (245 hp) and 480 Nm (345.03
lb-ft) of torque. Average fuel consumption is below 6.4 liters per
100 km (36.75 US mpg). The sedan can travel at speeds of up to 100
km/h (62.14 mph) on electric power alone, and cover around three
kilometers (1.86 miles) with zero local emissions at a constant speed
of 60 km/h (37.28 mph).

The Audi flagship model is designed as a highly efficient parallel
hybrid. The 2.0 TFSI, which has been modified in some areas,
generates an output of 155 kW (211 hp) and 350 Nm (258.15 lb-ft) of
torque, which is available between 1,500 and 4,200 rpm. The
combustion engine works together with a disc-shaped electric motor
which develops 40 kW (54 hp) and 210 Nm (154.89 lb-ft).

The permanent magnet synchronous motor is mounted in the space usually
occupied by the torque converter in front of the modified eight-speed
tiptronic. A multi-plate clutch that operates in an oil bath connects
or disconnects the electric motor and the TFSI engine. The clutch
operates ultra-precisely and gently in all situations. The highly
comfortable and fast-shifting hybrid transmission guides the torque
to the front wheels; with its wide gear spread it contributes to the
efficiency of the Audi A8 hybrid.

The short-term system output of 180 kW (245 hp) and the system torque
of 480 Nm (354.03 lb-ft) ensure highly agile performance. The Audi A8
hybrid reaches 100 km/h (62.14 mph) in 7.7 seconds from a standing
start and has a top speed of 235 km/h (146.02 mph). Its fuel
consumption in the EU cycle is less than 6.4 liters per 100 km (36.75
US mpg), and CO2 emissions are below 148 grams per km (238.18 g/mile).
Please note that all figures are provisional.

The Audi A8 hybrid can drive at up to 100 km/h (62.14 mph) purely on
electric power and has a range of up to three kilometers (1.86 miles)
at a constant 60 km/h (37.28 mph). This gives the driver the choice of
three modes: The EV characteristic map gives priority to the electric
drive, while the D mode efficiently controls both the engine and the
electric motor. The S mode and the tiptronic gate are designed for a
sporty driving style. The hybrid sedan has five operating states:
with the TFSI engine alone, with electric drive only or in hybrid
mode; recuperation and boosting are also possible. Two displays show
the driver all operating modes in detail.

The lithium-ion battery, which weighs 36.7 kilograms (80.91 lb), is
located in a crash-proof area in the trunk. It provides 1.3 kWh of
nominal energy and up to 40 kW of power. Two different methods are
used to air-cool the battery, depending on need: with air blown from
the passenger compartment by a fan and via a separate cooling circuit
coupled to the automatic air conditioning system. The battery is thus
kept within the temperature window required for it to perform to its
full potential over a wide range. The electric motor and the compact
power electronics which serve as a controller between the electric
motor and the battery are water-cooled.

In visual terms, the Audi A8 hybrid is distinguished by subtle
details. The ten spokes of its alloy wheels – which have a diameter
of 18 inches as standard and 19 inches as an option – are reminiscent
of turbine blades. The body features hybrid badges, and Arctic Silver
is available as an exclusive paint finish. The metallic paint finish,
three-zone automatic air conditioning, LED headlights and the BOSE
sound system come standard.

Thanks to the brand's ultra-lightweight construction expertise, the
Audi A8 hybrid will be one of the lightest sedans in its category.
Its ASF (Audi Space Frame) body is made entirely of aluminum, while
the B-pillars are of hot-shaped, ultra-high-strength steel. Weighing
just 231 kilograms (509.27 lb), it is roughly 40 percent lighter than
a comparable steel construction.

Nice car except... Bose? Seriously? The Bose that came in my A3 was a
downgrade from common factory equipment. No crossovers to prevent high
frequency distortion, no sound dampening to prevent muddying resonation
and echoes behind the speakers, and very little bass power. It was
complete crap to shave $30 off the cost of a sound system in a $35K car.
