Audi unveiled the eighth generation of its successful A6 full-size sedan; all engines feature Audi’s 48V mild-hybrid (MHEV) system as standard equipment. In Audi’s new mild-hybrid technology, a belt alternator starter (BAS) works together with a lithium-ion battery.
The Audi A6 can coast between 55 and 160 km/h (34.2 and 99.4 mph). The start-stop function kicks in at speeds up to 22 km/h (13.7 mph); the engine is restarted from standstill predictively. During deceleration, the BAS recovers up to 12 kW of energy. In real-world driving, the MHEV technology reduces fuel consumption by up to 0.7 liters per 100 kilometers.
