Audi has introduced its updated Q7, along with two diesel engines that the SUV will launch with. Shortly after the market introduction in September, gasoline and plug-in hybrid variants will follow.
Equipped with mild-hybridization, the Q7 powertrain has been developed with efficiency in mind. This means that consumption can be reduced by up to 0.7l/100km.
The central component of the system, the belt alternator starter (BAS), powers a 48V main electrical system in which a compact lithium-ion battery stores the energy.
During braking, the BAS can recover up to 8kW of power and feed it back into the battery. If the driver takes their foot off the accelerator at speeds between 55km/h and 160km/h, the SUV recuperates energy, rolls in idle or coasts for up to 40 seconds with the engine switched off.
The BAS restarts the engine the next time the accelerator is depressed, and does so faster and more gently than a conventional starter. The start‑stop range begins at 22km/h.
All of the engines in the Audi Q7 are coupled to an eight-speed tiptronic and permanent all‑wheel drive.
