What's New
The 2021 Audi A4 engines adopt mild hybrid technology, resulting in 13 extra horsepower. All-wheel drive is now standard on all models, along with lane departure warning, wireless Apple CarPlay, and an integrated toll-paying feature.
The Convenience Package for the Premium trim gains a heated steering wheel and front and rear parking sensors. The Premium Plus picks up standard adaptive cruise control, lane keeping assist, a surround-view camera system, and a driver alertness monitor with hands-on-the-wheel detection. Heated rear seats are now standard on the Prestige trim.
The current A4 debuted in 2017 and received a significant refresh last year.
