How does the Audi A4's reimagined design improve performance and efficiency?

I recently heard about the redesigned Audi A4 and was wondering if it offers any performance or efficiency upgrades. Can you explain how the new design elements contribute to these improvements?

The new aerodynamic body shape of the Audi A4 not only enhances its overall look, but also reduces drag and improves handling at high speeds.

The front-mounted intercooler in the Audi A4's engine helps cool the compressed air before it enters the engine, resulting in better performance.

The redesigned suspension system in the Audi A4 allows for a smoother and more comfortable ride, without compromising on handling and responsiveness.
