Why it stands out

The 2021 BMW 4 Series makes a bold statement with its distinctive design and modern technology. This model has evolved from the previous iterations, offering enhanced luxury and performance. With two engine options – a 2.0-liter turbocharged four-cylinder in the 430i and a more powerful 3.0-liter inline-six in the M440i – the 4 Series caters to various driving preferences, providing a robust 255 to 382 horsepower depending on the variant. Notably, the design includes a massive new twin-kidney grille for better cooling, though opinions on its aesthetics may vary. The interior boasts an impressive tech suite with the BMW iDrive 7 infotainment system, providing high-quality graphics and user-friendly operation. While the driving dynamics deliver a composed ride, some reviewers noted that the transmission could delay response times. Safety features are plentiful, including lane-departure warning and automatic emergency braking, contributing to BMW's reputation for building secure vehicles.
