2021 BMW 5 Series vs 2022 Mercedes-Benz S-Class

BMW was once known for sports sedans, and the 5 Series was one of the most prolific of those sedans. Sitting between the 3 Series and 7 Series in size and price, previous generations of 5 Series were known for a balance of performance and luxury, with impeccable engineering throughout.

Today, the BMW 5 Series is largely irrelevant. The 3 Series is now so big that there is less reason to upgrade, and most buyers are more interested in SUVs anyway. The competition—including the Audi A6, Jaguar XF, Mercedes-Benz E-Class, and Volvo S90—has also gotten better.

That doesn’t mean BMW has given up on the 5 Series. The current generation (codename G30) arrived for the 2017 model year, but it gets a midcycle refresh (or LCI, short for “Life Cycle Impulse,” in BMW speak) for 2021. Major updates include a 48-volt mild-hybrid system, a bigger infotainment touchscreen, and subtle styling changes.

The 2021 BMW 5 Series is not like the 5 Series models of old. That may drive away hardcore car fans, but the 2021 model makes a strong case to new-car buyers, maintaining sportier-than-average driving dynamics, along with the tech and luxury features expected of a car in this segment.
