Inside the 2024 GLB is an improved interior, which has two 10.25-inch displays for the instrument cluster and multimedia screens. The steering wheel is upholstered in Nappa leather as standard, and customers can specify a heated steering wheel with the AMG Line interior for the first time.

The latest GLB is equipped with a new mild-hybrid system that includes an additional 48-volt electrical system for the belt-driven starter-generator. It provides – briefly – another13 horsepower for starting and quicker acceleration conditions allow. The starter-generator also said to provide smooth, quiet engine starting, as well as coasting with the combustion engine switched off for greater efficiency. During braking and acceleration, it recuperates energy to supply the 12-volt on-board network and 48-volt battery with electrical energy.

The standard equipment of the GLB includes Highbeam Assist, as well as a USB package, Parking package and Keyless GO. Further optional equipment is bundled into upgrade packages. Active Steering Assist, an upgrade of the Driver Assistance package, enables more comfortable control of Lane Keeping Assist. The next generation Parking package also supports longitudinal parking with 360-degree visualization for camera-assisted parking.
