The front-wheel-drive, petrol 2.0 TFSI and diesel 2.0 TDI are examples of Audi's engine downsizing philosophy which sees large engine capacity replaced by smart forced induction techniques to achieve outstanding fuel consumption while maintaining performance and driving enjoyment.
The most fuel-efficient engine in the new A6 is the 2.0 TDI. Almost entirely redeveloped, it generates 130kW/380 Nm.
A multitronic CVT transmission drives the front wheels to give fuel consumption of 5.0 L/100km. It's capable of the 0-100km/h sprint in 8.2 seconds.
The turbocharger with adjustable vanes (VGT) provides spontaneous torque buildup at an early stage in the cycle.
The 132kW/320Nm turbo petrol 2.0 TFSI engine uses Audi's valvelift system which varies the lift of the exhaust valve.
Paired with the multitronic transmission and front-wheel drive, this engine propels the A6 from 0-100 km/h in 8.3 seconds. The engine consumes 6.4L/100 km.
Both of these new four-cylinder A6 variants utilise Audi efficiency technologies, including an innovative thermal management system that lowers fuel consumption by approximately 0.1 litres per 100km.
A start-stop system is also standard across the A6 range and shuts off the engine after the Audi A6 has come to a stop for further fuel savings.
The energy recovery system utilises the kinetic energy of the car as it decelerates.
Among the technologies in the A6 lineup is the latest version of Audi's Drive Select dynamic handling system, which now includes an additional mode the Efficiency program.
