In the engine line-up, the GLA and GLB get the addition of 48V mild-hybrid tech across all petrol engine options. Additionally, Mercedes says it has improved the performance of the plug-in-hybrid powertrain offered in the GLA. Both SUVs are available with either a 1.3-litre turbo-petrol or 2.0-litre turbo-petrol engine as well as a 2.0-litre diesel in varying states of tune.

Moving to the PHEV, Mercedes has uprated the electric motor extracting a further 7 bhp with the system also supporting higher charging speeds of up to 22 kW. Range too has improved from the previous model with the updated PHEV capable of being driven as an EV for up to 70 km – up from 60 km.


The AMG 35 variants too benefit from the mild hybrid tech along with the updated looks. The models also feature the new Affalterbach AMG badge on the bonnet in place of the traditional three-point star.

The updated GLA and GLB will hit global markets in the coming months after which we could expect the models to make their way to India.
