Audi’s A6 family has been updated for 2015 with revised engines, transmission, headlights and an improved infotainment system. The range sees an improvement in fuel efficiency, while the A6 allroad quattro, S6, S6 Avant and RS 6 sport models receive several new features.
The engine lineup for the new A6 and A6 Avant includes three TFSI units with output ranging between 140 kW and 245 kW and five TDI units ranging from 110 kW to 240 kW. The efficiency-focused petrol and diesel engines bear the “ultra” label. Combined with the all?new S tronic transmission, the 1.8 TFSI ultra consumes 5.7 litres of fuel per 100 kilometres, while the 2.0 TDI ultra with 110 kW sips a frugal 4.2 litres of fuel per 100 kilometres.
Six cylinder petrol and diesel engines have been thoroughly revised. The 3.0 TDI clean diesel is available with either 160 kW or 200 kW. The 3.0 TDI clean diesel biturbo produces 235 kW. Another version with 240 kW, which can be boosted briefly to 255 kW, 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 the newly designed six?speed manual transmission that is particularly lightweight and low-friction, or a seven?speed S tronic. Front-wheel drive versions receive a fully redeveloped dual-clutch transmission in plate of the multitronic. For models with 200 kW and above, quattro permanent all?wheel drive can be supplemented with the sport differential, which actively distributes power between the rear wheels.
All A6 models have Audi’s drive select dynamic handling system as standard, while a choice of two sport suspensions and adaptive air suspension are available as options. In the A6 Avant 2.0 TDI ultra with 140 kW, the springs are made of fibreglass-reinforced polymer (GFRP) – the brand’s new innovation that saves approximately 4.4 kg of weight, reduces fuel consumption and improves both driving precision and vibrational comfort. The wheels measure between 17 and 20 inches.
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. There are four 3.0?litre, V6 engines from which to choose – the 3.0 TFSI and three versions of the 3.0 TDI. The adaptive air suspension is standard in the allroad quattro models.
The new Audi S6 and the S6 Avant are powered by a 4.0 TFSI biturbo V8 producing 331 kW, accelerating the Sedan from 0 to 100 km/h in 4.4 seconds, and the S6 Avant wagon in 4.6 seconds. Average fuel consumption is rated at 9.2L/100km in the Sedan and 9.4L/100km in the Avant. This efficiency is due in large part to the cylinder on demand (COD) system, which only activates four of the eight cylinders when under light throttle 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 millimetres. 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 flagship bahn-stormer accelerates to 100 km/h in just 3.9 seconds and reaches a top speed of 305 km/h. Its 4.0 TFSI engine produces 412 kW, yet consumes on average just 9.6 litres of fuel per 100 kilometres, all thanks to COD technology.
An eight?speed tiptronic transfers the power from the biturbo V8 to all four wheels. The RS adaptive air suspension lowers the body by 20 millimetres. 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.
The new Audi A6 will arrive in Australia in March. The local model range, pricing and specification will be announced closer to launch.
