The engine lineup for the new A6 and A6 Avant includes three TFSI units with output ranging between 140 kW (190 hp) and 245 kW (333 hp) and five TDI units ranging from 110 kW (150 hp) to 240 kW (326 hp). All engines comply with the limits of the Euro 6 emission standard, and their CO2 emissions have been reduced by as much as 22 percent. At Audi, the most efficient gasoline and diesel engines bear the 'ultra' label. Combined with the all-new S tronic transmission, the 1.8 TFSI ultra consumes just 5.7 liters of fuel per 100 kilometers (41.3 US mpg), corresponding to 133 grams CO2 per kilometer (214 g/mi). The 2.0 TDI ultra with 110 kW (150 hp) achieves the extremely low consumption figure – with no restrictions with respect to equipment – of 4.2 liters of fuel per 100 kilometers (56.0 US mpg) corresponding to 109 grams CO2 per kilometer (175.4 g/mi). The top gasoline engine, the 3.0 TFSI, has been comprehensively revised. The engine developers have also completely redesigned numerous aspects of the 3.0 TDI clean diesel, which is available with either 160 kW (218 hp) or 200 KW (272 hp). The 3.0 TDI clean diesel biturbo produces 235 kW (320 hp). Another version with 240 kW (326 hp), which can be boosted briefly to 255 kW (346 hp), powers the A6 3.0 TDI competition and A6 Avant 3.0 TDI competition special-edition models, with which Audi is celebrating the 25 years of TDI technology. The high-performance diesel is paired with an eight-speed tiptronic. All other engine variants work together with either a newly designed six-speed manual transmission that is particularly lightweight and low-friction, or a seven-speed S tronic. In the versions with front-wheel drive, a fully redeveloped dual-clutch transmission replaces the multitronic. In engine configurations starting at 200 kW (272 hp), quattro permanent all-wheel drive can be supplemented with the sport differential, which actively distributes power between the rear wheels. The chassis with its sophisticated wheel suspensions also combines supreme comfort with sporty handling. The Audi drive select dynamic handling system is standard, and Audi offers a choice of two sport suspensions and adaptive air suspension as options. In the A6 Avant 2.0 TDI ultra with 140 kW (190 hp), the springs are made of glass fiber-reinforced polymer (GFRP) – an Audi innovation that saves approximately 4.4 kilograms (9.7 lb) of weight, reduces fuel consumption and improves both driving precision and vibrational comfort. The wheels measure between 17 and 20 inches diagonal.
Extensively updated: the engine lineup
The new Audi A6 allroad quattro, which is based on the A6 Avant, features a raised body and stainless steel linings that encapsulate the underside of the front and rear ends. The design is robust and masculine, with vertical slats in the Singleframe grille. There are four 3.0-liter, V6 engines from which to choose – the 3.0 TFSI and three versions of the 3.0 TDI. The adaptive air suspension is standard.
Sophisticated and masculine – the new Audi A6 allroad quattro
The new Audi S6 and the S6 Avant are sports cars for everyday. The 4.0 TFSI, a biturbo V8 producing 331 kW (450 hp), accelerates the Sedan from 0 to 100 km/h (62.1 mph) in 4.4 seconds. The S6 Avant completes the sprint in 4.6 seconds. Average fuel consumption is just 9.2 liters per 100 kilometers (25.6 US mpg) in the Sedan and 9.4 liters (25.0 US mpg) in the Avant, the equivalent of 214 and 219 grams CO2 per kilometer (344 and 352.4 g/mi), respectively. This efficiency is due in large part to the cylinder on demand (COD) system, which only activates four of the eight cylinders when under part load. Standard equipment in the new Audi S6 and S6 Avant includes quattro permanent all-wheel drive and the adaptive air suspension, which lowers the body by 20 millimeters (0.8 in). Matt black brake calipers grip the front discs mounted behind the 19-inch wheels. The dynamic top model of the new A6 family is the Audi RS 6 Avant. The high-performance sports car for everyday driving and recreation accelerates to 100 km/h (62.1 mph) in 3.9 seconds and reaches a top speed of 305 km/h (189.5 mph). Its 4.0 TFSI engine produces 412 kW (560 hp), yet consumes on average just 9.6 liters of fuel per 100 kilometers (24.5 US mpg, corresponding to 223 grams CO2 per kilometer (358.9 g/mi). The COD system is also largely responsible for this efficiency. An eight-speed tiptronic transfers the power from the biturbo V8. The standard quattro drivetrain uses a center differential with a higher locking rate. The RS adaptive air suspension lowers the body by 20 millimeters (0.8 in). Audi offers the taut RS sport suspension with Dynamic Ride Control (DRC) as an option. The large brake discs feature a weight-saving wave design, and the wheels measure 20 inches in diameter. 21-inch wheels are available as an option. Delivery of the new Audi A6 family will begin in fall 2014. The base price in Germany for the Sedan with the 1.8 TFSI will be €38,400; the A6 Avant 1.8 TFSI begins at €40,900 and the A6 allroad quattro 3.0 TDI at €56,650. The Audi S6 is priced at €75,400, and the Audi RS 6 Avant lists for €108,900.
