Earlier today we talked about the 2015 A6 Sedan / Avant Facelift as well as by the 2015 A6 Allroad Quattro Facelift, but we didn’t tell you folks anything about the new S6, S6 Avant and RS6 Avant models. As expected, these models also receive the new headlights that are available as an option with LED or matrix LED technology, as well as with redesigned LED design for the taillights.
The S6 and S6 Avant are powered by the same 4.0-liter TFSI biturbo V8 engine that delivers 450 hp (331 kW) and 550 Nm of torque. The V8 engine pushes the 2016 Audi S6 Facelift from 0 to 100 km/h (62 mph) in 4.4 seconds, while the S6 Avant Facelift needs 4.6 seconds to achieve the same speed, while top speed is electronically limited at 250 km/h or 155 mph.
Despite these impressive performances, the average fuel consumption is just 9.2 liters per 100 km (25.6 US mpg) in the Sedan and 9.4 liters (25.0 US mpg) in the Avant. CO2 emissions are 214 g/km in the Sedan and 219 g/km in the Avant. According to Audi, the impressive fuel consumption is achieved thanks to the cylinder on demand (COD) system, able to activate four of the eight cylinders when under part load.
According to Audi, the facelifted 2015 S6 and S6 Avant arrive as standard with the Quattro permanent all-wheel-drive system, adaptive air suspension which brings the body 20 mm closer to the ground. In addition, both vehicles get the matt black brake calipers in the front discs and 19-inch wheels.
The 2015 Audi RS6 Avant Facelift uses the same 4.0-liter TFSI V8 biturbo engine that generates 560 hp (412 kW).
As a result, the RS6 Avant zooms from 0 to 100 km/h (62 mph) in 3.9 seconds, with a top speed limited at 305 km/h or 189.5 mph. Thanks to the 8-speed tiptronic transmission and cylinder on demand (COD) system, fuel consumption is 9.6 liters of fuel per 100 km (24.5 US mpg), while CO2 emissions are 223 grams per km.
RS6 Avant also features the adaptive air suspension, which brings its body 20 mm closer to the ground, while as an option the Dynamic Ride Control (DRC) is offered. 20-inch wheels are offered as standard, while a bigger diameter of 21-inch comes as an option. The 2015 Audi S6 Facelift is priced at 75,400 euros in Germany, while the RS6 Avant Facelift starts at 108,900 euros. [source: Audi]
