A Bold Design Evolution
The latest design language for the BMW 4 Series draws heavy inspiration from the spectacular Concept 4 Series. The front end is defined by a broad, contoured appearance that varies across the SE, Sport, and M Sport trims.
Key exterior highlights include:
- New Twin LED Headlights: Standard across the range with a “cropped” eyebrow design.
- L-Shaped Rear Lights: Homogenous LED curves that accentuate the wide, muscular rear wheel arches.
- Aggressive Air Intakes: A larger central aperture that increases in size toward the outer edges for a more imposing road presence.
Performance and Powertrain Specs
The BMW 4 Series is built on a chassis with a lower center of gravity than the 3 Series, providing the agility expected of a true sports car. From the efficient 420d to the blistering M4, there is a powerplant for every type of driver.

The BMW M4: High-Performance Benchmark
