Changes to the new lineup's styling include a revised single-frame grille, restyled bumpers, larger air vents and new-shape fog lights. The optional xenon and LED daytime running lights package has also been updated, with a new adaptive light, dynamic cornering light system, and a high-beam assistant to automatically switch between high and low beams also available.
At 4.93m long, 1.86m wide, and 1.46m high, little has changed in the sedan’s proportions. The gentle lip on the trunk, integrated chrome strip on the bumper, broad diffuser and straight exhaust pipes complete the list of changes at the rear. There are also five new exterior colors to choose from.
Inside, the cars receive an updated instrument panel, new chrome trim and optional Valcona leather for the seats. The sporty S-line package is once again available at launch, coming with 18in wheels and a 30mm lowered suspension kit.
The most significant upgrade for the 2009 facelifted A6 is without doubt the new range of engines. New measures have been introduced to optimize fuel consumption without sacrificing performance, with fuel economy over the whole A6 family being improved by 15%. The improvements are brought about by the addition of a power steering pump that operates on demand, an alternator that regenerates electrical energy when the vehicle is coasting, a lowered ride-height and other aerodynamic fine-tuning. Also new is Audi’s latest valve lift system, which manages the inlet valve timing for improved torque levels.
The smallest petrol engine is the 2.0L TFSI, a 170hp (125kW) turbocharged four-cylinder unit. At the other end of the spectrum is the 4.2L FSI, a 350hp (257kW) V8. The other petrol units include two new 2.8L FSI engines, developing 190hp (140kW) and 220hp (162kW) respectively, and a brand new 290hp (213kW) 3.0L V6 TFSI supercharged mill. This latter engine comes standard with tiptronic auto and quattro AWD, and is capable of accelerating from 0-100km/h in 5.9 seconds and on to an electronically controlled top speed of 250km/h. Fuel consumption rates at 25mpg (9.5L/100km) for the mixed cycle.
The new diesel lineup consists of entry-level 2.0L four-cylinder TDI with 136hp (100kW) and is followed by a 170hp (125kW) version of the same engine. Next up the line is a 2.7L V6 TDI with 190hp (140kW) and 280lb-ft (380Nm of torque), and this is followed by a 3.0L V6 oil-burner with 240hp (176kW) and 332lb-ft (450Nm) of torque. The most fuel efficient model is the 2.0L TDIe (efficiency model), which rates in at 44.4mpg (5.3L/100km) for the mixed cycle.
Audi quattro four-wheel drive is available on all engines with 190hp (140kW) or above and is standard equipment on high-end aggregates. Other mechanical changes for the 2009 A6 lineup include new large-diameter front-axle shock absorbers and modified spring rates.
The facelifted Audi A6 will be available in European showrooms this October and will start at €34,200 (approximately $51,020) for the 2.0L TFSI sedan.
