Audi A5 Mild Hybrid 12 Volt Drivetrain

Audi A5 Coupé

The updated Audi A5 models (combined fuel consumption in l/100 km: 5.4–3.7 (43.6–63.6 US mpg); combined CO2emissions in g/km: 143–98 (230.1–157.7 g/mi)) are available in Europe with an output range from 120 kW (163 hp). This includes the S models with their powerful V6 engines. The engines satisfy the limits of the Euro 6d-temp emissions standard.

Four A5 engine variants will be equipped with a mild hybrid system (MHEV). A belt alternator starter, which is connected to the crankshaft, recovers energy during deceleration and stores this in a compact lithium-ion battery. With the four-cylinder engines, the MHEV system is integrated into the 12-volt electrical system and into a new 48-volt main electrical system in the S TDI models. With the S5 TDI, for example, Audi measurements show that this electrification can reduce fuel consumption in everyday operation by up to 0.4 liters per 100 kilometers by means of recuperation or shutting down the engine when the driver lifts off of the accelerator. The start-stop range begins at an unusually high speed; restarts are fast and smooth.
