Safety in the BMW 3 Series vs BMW 5 Series

The BMW 3 Series and the BMW 5 Series have multiple driver-assist safety features. These systems can sometimes take control of a vehicle if an accident is imminent.

The BMW 3 Series has standard Active Guard with Frontal Collision Warning and Automatic City Collision Mitigation and Braking. This system uses cameras and radar to monitor for accidents. If the system senses an accident might happen, you'll get an alert, and if the accident is imminent, the system will apply the brakes.

The BMW 3 Series also has standard Automatic high beams. The Automatic high beams sense the darkness levels and turn on the high beams when it gets dark enough. When another vehicle passes by, the beams lower to avoid blinding the other driver.

The BMW 5 Series has a few more standard safety options. The 5 Series has a standard Active Driving Assistant, including Frontal Collision Warning, Active Blind Spot Detection, Lane Departure Warning, and Speed Limit Information. While this is standard on the 5 Series, certain features are available on the 3 Series.
