Audi’s latest A6 sedan variant employs a twin-turbo V6 diesel with 230kW of power and 650Nm of torque to race from standstill to 100km/h in 5.1 seconds.
That speed places the Audi A6 Biturbo diesel ahead of the BMW X6 M50d and the upcoming Audi SQ5 SUVs, and its twin Audi A7 3.0 TDI Biturbo that all complete the benchmark sprint in 5.3 seconds.
It’s the quickest model in the A6 range, four-tenths ahead of the supercharged V6 petrol 3.0 TFSI, while a $118,800 price tag also confirms its position as the flagship of the regular A6 range that comprises six variants not including the S6 and forthcoming RS6.
The addition of the 3.0 TDI Biturbo means petrol and diesel offerings are evenly split, though the latter account for 58 per cent of Audi A6 sales in Australia.
Standard features for the twin-turbo Audi A6 3.0 TDI include 18-inch alloy wheels, Audi Drive Select, parking sensors and rear view camera, Bose surround sound audio system, Bluetooth with streaming, sunroof, navigation, xenon headlights and Milano leather seats.
The Audi A7 3.0 TDI Biturbo costs from $148,600 and its equipment highlights different to its sedan sibling are 19-inch alloy wheels, four-zone climate control, automatic tailgate, Valcona leather upholstery, and a front as well as rear view camera.
Both models are the first A6 models to use a ZF eight-speed automatic that is better suited to the Biturbo’s torque output than the seven-speed dual-clutch unit found in other V6 variants.
The Audi A6 3.0 TDI Biturbo competes directly with the $121,500 BMW 535d, $115,500 Jaguar XF 3.0D and $136,485 Mercedes-Benz E350 CDI.
