Mercedes has updated its A-Class and B-Class models for 2023, introducing revised technology and new electrified powertrains.

Prices for the entry-level A-Class start from £31,905 OTR for an A 180 Sport Executive hatchback, while those opting for a B-Class will pay £35,125 for a B 200 Sport Executive.

Four model lines are available; Sport Executive, AMG Line Executive, AMG Line Premium and AMG Line Premium Plus.

Standard equipment across both models includes heated front seats, parking sensors, reversing camera and LED headlamps.

AMG Line models have a sportier appearance, both inside and out.

A plug-in hybrid powertrain is only available on the A-Class saloon and is priced from £41,340.

A 1.3-litre turbocharged petrol unit powers the A 180, A 200, and B 200, paired with a seven-speed automatic transmission. The 180 produces 136PS and the 200 produces 163PS. CO2 emissions start at 133g/km for the A-Class and 136g/km for the B-Class.

There's also a 2.0-litre diesel powertrain, offered in A 200d and B 200d, with 150PS.

Mercedes has updated the plug-in hybrid A 250e model with a larger battery, extending its zero-emission capability. The battery has a capacity of 15.6kWh, which provides a WLTP range of more than 40 miles.

The battery can be charged a more quickly, too, as it now features 11kW AC charging capability as well as 22kW DC charging.

The A-Class was the first Mercedes model to feature the brand’s MBUX infotainment system and the updated A-Class and B-Class feature an updated version. Changes to the instrument cluster display provide a simplified layout, while the voice control system has been enhanced to explain and assist with vehicle functions.

The new models are available to order now.
