Audi A6/A7 Mild Hybrid 48V real-life test (55 TFSI) :: [1001cars]

The Audi A6 and A7 with six and eight-cylinder engines use a 48V MHEV system. The 48V system is equipped with a belt alternator starter, which instantly and smoothly restarts the combustion engine. At the same time, it extends the start-stop system to up to 22 km/h (13.7 mph). Between 55 and 160 km/h (34.2 – 99.4 mph) Audi A6 and A7 can coast fuel-efficiently with the combustion engine shut off. The drive management decides on the suitable strategy. The lithium-ion battery housed in the rear stores the recovered energy and passes this onto auxiliary consumers such as the air conditioning or the oil pump in the transmission. In real-world driving, fuel savings of up to 0.7 liters (0.2 US gal) are possible.
