How does the new Audi A3's hybrid engine improve fuel efficiency?

I am interested in purchasing the Audi A3 but I am unsure about its fuel efficiency. Can you provide information on how the new hybrid engine in the Audi A3 improves its fuel efficiency compared to previous models?

The new Audi A3 has a hybrid engine that combines traditional gas power with an electric motor. This helps to improve its fuel efficiency by utilizing energy that would normally be wasted while driving. As a result, the A3 is able to achieve better gas mileage and reduce emissions.

The A3's hybrid engine operates in three different modes: electric, gas, and hybrid. This allows the car to use more electric power during city driving, where speeds are lower and there are more opportunities to regenerate energy. On the highway, the A3 will rely more on its gas engine, but still utilizes its electric motor for added boost and efficiency.
