Why it stands out

The 2021 BMW 4 Series is a notable evolution from previous models, characterized by its bold and unconventional styling, particularly the large twin-kidney grille that sets it apart visually. This model offers impressive performance through its dual-engine options—the 430i with a 2.0-liter turbocharged engine producing 255 horsepower and the M440i with a 3.0-liter inline-six generating 382 horsepower. The 4 Series also excels in technology, featuring the advanced BMW iDrive 7 infotainment system, which includes seamless smartphone integration and refined interface options. While its interior provides a luxurious experience, it has received some criticism for its somewhat polarizing design and cramped rear seating, which may deter some buyers. However, for those looking for a sporty and stylish coupe with a modern tech-focused setup, the 2021 BMW 4 Series remains a strong contender in its segment.
