In Frankfurt next month, Audi will show up to the show with the new Audi A8 Hybrid, which will enter series production in 2012.
The 2013 Audi A8 Hybrid will be powered by a pretty efficient parallel hybrid system, which includes a 2.0 liter TFSI 4-cylinder turbo engine making 211-hp and 258 lb-ft of torque and an electric-motor making 54-hp and 155 lb-ft of torque. Together, the system outputs 245-hp with a maximum torque of 345.03 lb-ft. Mated to an 8-speed tiptronic transmission, the A8 Hybrid goes from 0 to 62 mph in 7.7 seconds with a top speed of 146 mph.
What about the fuel-efficiency? Audi says that the A8 Hybrid can travel at speeds of up to 62 mph on electric power alone, and cover around 1.86 miles with zero local emissions at a constant speed of 37. Fuel-consumption comes in under 6.4 liters per 100 km or 36.7 mpg in U.S. terms.
The 2013 Audi A8 Hybrid will make its public debut at the 2011 Frankfurt Motor Show next month. Prices and dealership availability will be announced closer to launch.
2013 Audi A8 Hybrid:
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.
