on 2 October 2018. At launch, the vehicle was claimed to feature the Intelligent Drive semi-automated driving system borrowed from the S-Class. The vehicle received a facelift in 2023. The design was improved with a much shorter front overhang. The controversial sculpting on the side part of the vehicle was not carried over to the W247 B-Class. Three infotainment system options is available, with entry-level models getting dual seven-inch displays. A seven-inch display with the larger 10.25-inch display is available, with top-tier models getting a pair of the large displays. It is powered by a full MBUX infotainment system, giving B-Class buyers access to its functions through a standard touchscreen. Features such as intelligent voice control, augmented reality, and a head-up display are optional. The all-electric configuration was removed, but a plug-in hybrid option was introduced. The plug-in hybrid comes with a 10.9 kWh battery which optionally supports DC charging and provides a WLTP combined cycle range of 66 km.
