Three TFSI and five TDI engines with outputs ranging from 110 kW (150 hp) to 245 kW (333 hp) – the reorganized engine lineup for the Audi A6* and A6 Avant* covers the full breadth of customer expectations. All engines comply with the Euro 6 emission standard. Their CO 2 emissions have decreased by as much as 22 percent, while output has increased by up to 35 kW (48 hp). As forced-induction, direct-injection engines, all follow Audi’s right-sizing philosophy.
The start-stop-system in combination with the seven-speed S tronic and the eight-speed tiptronic offers added features. When the driver rolls up to a red light or other obstacle, the engine can be deactivated as soon as speed drops below seven km/h (4.3 mph). This function remains inactive in S mode and in the touch control gate of the seven-speed S tronic. The new start-stop-system works closely together with the ACC stop&go. When the engine is inactive, it starts again as soon as the vehicle ahead begins moving.
The entry-level gasoline engine is now the 1.8 TFSI. The 1,798 cc, four-cylinder unit produces 140 kW (190 hp) and 320 Nm (236.0 lb-ft) of torque, the latter between 1,400 and 4,100 rpm. Special features of the engine include dual injection in the combustion chambers and the induction pipe, the exhaust manifold integrated into the cylinder head and the Audi valvelift system (AVS) for the exhaust valves.
The 1.8 liter gasoline engine is already powerful enough to make the new Audi A6 and A6 Avant very agile. When paired with the S tronic (manual transmission), the Sedan sprints from 0 to 100 km/h (62.1 mph) in 7.9 (7.9) seconds with a top speed of 233 (233) km/h (144.8 mph). Average fuel economy, however, is just 5.7 (5.9) liters per 100 kilometers (41.3 [39.9] US mpg), corresponding to 133 and 138 grams CO2 per kilometer (214.0 [222.1] g/mi). In combination with the S tronic (manual transmission), the Avant accelerates from 0 to 100 km/h (62.1 mph) in 8.2 (8.2) seconds on its way to a top speed of 225 (226) km/h (139.8 mph [140.4]). Fuel consumption figures of 5.9 (6.2) liters of gasoline per 100 kilometers (39.9 [37.9] US mpg), with 137 and 144 grams CO2 per kilometer respectively (220.5 [231.7] g/mi), are low. As the most efficient gasoline model in the A6 family, the 1.8 TFSI with S tronic bears the “ultra” badge.
The 2.0 TFSI uses the same technology package as the 1.8 TFSI. It has an output of 185 kW (252 hp), and 370 Nm (272.9 lb-ft) of torque is available between 1,600 and 4,500 rpm. The lightweight two-liter unit, which displaces 1,984 cc, accelerates the new A6 Sedan with front-wheel drive from zero to 100 km/h (62.1 mph) in 6.7 seconds on its way to a governed top speed of 250 km/h (155.3 mph). Average fuel consumption is a mere 5.9 liters per 100 kilometers (39.9 US mpg), corresponding to CO2 emissions of 137 grams per kilometer (220.5 g/mi). The values for the new A6 Avant with front-wheel drive are 6.9 seconds for 0 to 100 km/h acceleration, 6.0 liters of fuel per 100 kilometers (39.2 US mpg) and 140 grams CO2 per kilometer (225.3 g/mi).
Significantly revised: the 3.0 TFSI
Significantly revised, the 3.0 TFSI now develops 245 kW (333 hp) and has a maximum torque of 440 Nm (324.5 lb-ft) between 2,900 and 5,300 rpm. The 2,995 cc V6 uses a mechanical supercharger located in the V of the cylinder banks to compress the intake air. A new electromagnetic clutch deactivates the charger at low and intermediate loads and engine speeds. Dual-injection, adjustable intake and exhaust camshafts, and the measures to reduce friction are proven Audi efficiency technologies.
Powerful thrust and lightning-fast response – the three-liter V6 accelerates the new Audi A6 with S tronic and quattro all-wheel drive from standstill to highway speed in 5.1 seconds, with acceleration continuing up to a governed top speed of 250 km/h (155.3 mph). The sprint takes two tenths of a second longer in the new A6 Avant. The supercharged V6 in the Sedan averages 7.4 liters of fuel per 100 kilometers (31.8 US mpg) in the NEDC, corresponding to 172 grams CO2 per kilometer (276.8 g/mi). These same figures for the Avant are 7.6 liters (30.9 US mpg) and 177 grams CO2 per kilometer (284.9 g/mi).
Two variants: the 2.0 TDI ultra
The TDI engines include two output variants of the 1,968 cc four-cylinder unit – one with 110 kW (150 hp) and 350 Nm (258.1 lb-ft) from 1,500 to 3,000 rpm; the other with 140 kW (190 hp) and 400 Nm (295.0 lb-ft) from 1,750 to 3,000 rpm. The 2.0 TDI clean diesel boasts innovative solutions, with separate coolant loops, two balance shafts in the crankcase, variable valve drive and a common rail injection system that maintains the fuel at a max. pressure of 2,000 bars. The 2.0 TDI variants are characterized by high efficiency, which is why they bear the ultra badge.
Even the 110 kW version delivers powerful performance. The A6 Sedan with S tronic reaches the 100 km/h (62.1 mph) mark in 9.6 seconds and has a top speed of 214 km/h (133.0 mph) With the Avant these figures are 9.9 seconds and 209 km/h (129.9 mph). With average fuel consumption of just 4.2 and 4.4 liters per 100 kilometers (56.0 and 53.5 US mpg), respectively, corresponding to 109 grams CO2 per kilometer for the Sedan and 114 grams for the Avant (175.4 and 183.5 g/mi, respectively), both variants offer exemplary economy.
The 2.0 TDI clean diesel with 140 kW (190 hp) in combination with the S tronic and front-wheel drive is also extremely efficient. The new A6 Sedan consumes just 4.2 liters per 100 kilometers (56.0 US mpg), corresponding to 109 grams CO2 per kilometer (175.4 g/mi). These same figures for the new Avant are 4.4 liters per 100 kilometers (53.5 US mpg) and 114 grams CO2 per kilometer (183.5 g/mi). The performance figures: from 0 to 100 km/h (62.1 mph) in 8.2 (Avant: 8.5) seconds and top speed 232 km/h (Avant: 226) (144.2 and 140.4 mph respectively).
The TDI: three liter-V6 in three engine power classes
Audi offers three versions of the 3.0 TDI, which displaces 2,967 cc – as a comprehensively revised, highly efficient monoturbo in two power-output classes and as a powerful biturbo. Thanks to an emissions-control unit compliant with the Euro 6 emission standard, all versions of the V6 also bear the “clean diesel” designation.
The monoturbo, which weighs only around 190 kilograms (418.9 lb), features particularly effective thermal management, new cylinder heads and a modified chain drive. Its common-rail system generates up to 2,000 bars of pressure. In the efficiency version, which has been specifically designed for low fuel consumption, the 3.0 TDI clean diesel produces 160 kW (218 hp). Its torque of 400 Nm (295 lb-ft) is available between 1,250 and 3,750 rpm. The sportier version offers 200 kW (272 hp) and 580 Nm (427.8 lb-ft) of torque, the latter between 1,250 and 3,250 rpm.
Even in the version with 160 kW (218 hp), the 3.0 TDI clean diesel moves the new Audi A6 and A6 Avant with great ease. With front-wheel drive, the Sedan completes the standard sprint in 7.1 seconds and reaches a top speed of 244 km/h (151.6 mph); for the Avant these figures are 7.3 seconds and 234 km/h (145.4 mph). Fuel consumption is just 4.7 liters per 100 kilometers (50.0 US mpg) – a CO2 equivalent of 122 grams per kilometer (196.3 g/mi) [Avant: 4.8 liters per 100 kilometers/125 grams CO2 per kilometer (49.0 US mpg/201.2 g/mi)], an improvement of 15 percent compared with the previous engine.
In combination with the S tronic and quattro, the values for the A6 Sedan and the A6 Avant vary slightly. The standard sprint from 0 to 100 km/h (62.1 mph) is completed in 6.6 (Avant: 6.8) seconds, and top speed is 244 and 234 km/h (151.6 and 145.4 mph), respectively. According to the NEDC, the Sedan consumes 5.1 liters per 100 kilometers (46.1 US mpg) – a CO2 equivalent of 133 grams per kilometer (214.0 g/mi). For the Avant these figures are 5.3 liters (44.4 US mpg) and 138 grams (222.1 g/mi).
The 3.0 TDI clean diesel with 200 kW (272 hp) is even more impressive. The key figures for the A6 Sedan are 5.5 seconds for 0 to 100 km/h (62.1 mph) acceleration, a governed top speed of 250 km/h (155.3 mph), 5.1 liters of fuel per 100 kilometers (46.1 US mpg) and 133 grams CO2 per kilometer (214.0 g/mi). The values for the new A6 Avant: 5.7 seconds to highway speed, a governed top speed of 250 km/h (155.3 mph), 5.3 liters of fuel per 100 kilometers (44.4 US mpg) and 138 grams CO2 per kilometer (222.1 g/mi).
650 Nm: the 3.0 TDI clean diesel biturbo
The top TDI engine in the new A6 family is the 3.0 TDI clean diesel biturbo. It produces 235 kW (320 hp) and delivers a brawny 650 Nm (479.4 lb-ft) of torque to the crankshaft between 1,400 and 2,800 rpm. Its two turbochargers are connected in series via a changeover valve. The pistons, cylinder heads and camshafts have been specially designed for the high-performance concept. A sound actuator in the exhaust system gives the engine a full, sporty sound.
With the biturbo V6, the new A6 Sedan sprints from 0 to 100 km/h (62.1 mph) in 5.0 seconds. The governed top speed of 250 km/h (155.3 mph) is a mere formality. The sprint takes two tenths of a second longer in the new Avant. The consumption figures are 6.0 (6.2) liters per 100 kilometers (39.2 and 37.9 US mpg) for the Sedan and Avant, respectively, the equivalent of 159 and 164 grams CO2 per kilometer (255.9 and 263.9 g/mi).
For customers for whom sporty driving is particularly important, Audi offers the A6 and A6 Avant as a special edition 3.0 TDI competition model. The three-liter biturbo engine produces 240 kW (326 hp), with overboost making 255 kW (346 hp) available for brief periods. Both cars come equipped with the S line sport package, which also lowers the body by 20 millimeters (0.8 in). Sitting behind the 20-inch, two-tone wheels are brakes with red calipers.
The interior is all black, and the list of standard equipment is generous. Audi is using the two special edition models to commemorate the successful launch of its TDI technologies 25 years ago.
