Real MPG: BMW 3 Series (2019 on)

Real MPG

46.5

Average

Great to drive with a wide range of refined engines. Looks and feels very classy. New infotainment from late in 2022 means it's now entirely up-to-date.

Even used examples aren't cheap. The Skoda Superb is a bigger, more spacious alternative for less money.
