The 2027 BMW 4 Series runs Operating System 8.5 on a curved display that puts the driver's instruments and the central touchscreen under one piece of glass, and it is standard on every trim. So is the Driving Assistant safety package. The scope fact most shoppers get wrong is that the screen and the standard safety hardware do not change as you move up the range: a $51,200 430i Gran Coupe and a $77,200 M440i xDrive Convertible have the same interface and the same standard driver-assistance suite.

Below: the infotainment system, the hands-free and assisted-driving functions and exactly which trims they are bundled with, and the standard and available driver-assistance equipment across the range.

2027 BMW 4 Series Infotainment and Connectivity

The curved display is one continuous panel angled toward the driver, carrying the instrument cluster on the left and the touchscreen on the right. It runs Operating System 8.5 with the BMW Intelligent Personal Assistant, which takes natural voice commands rather than a fixed phrase list. Wireless Apple CarPlay and Android Auto are standard, as is wireless device charging, so the phone never needs a cable.

Navigation with real-time traffic is standard on every trim, which matters more here than in most markets: the difference between Interstate 80 and Highway 12 across Solano County on a bad afternoon is twenty minutes, and the system routes around it. Satellite radio and an in-car internet connection are also standard, along with ambient lighting through the cabin.

Driving Assistant and Hands-Free Functions

Every 2027 4 Series carries the standard Driving Assistant package. Stepping up to the available Driving Assistant Professional Package adds Traffic Jam Assistant, which manages steering, acceleration and braking in slow-moving traffic, among other functions. That is the package worth understanding before you order, because it is the one that changes the car on a congested commute rather than on a Sunday drive.

These are assistance systems, not autonomous driving. The driver remains responsible for the vehicle at all times, and the systems are designed to support attention rather than replace it.

Standard Driver Assistance Features

Standard across the entire 2027 4 Series range, on every trim and in every body:

• Active Blind Spot Detection
• Frontal Collision Warning with City Collision Mitigation
• Lane Departure Warning
• Traction control and stability control
• BMW emergency and security services
