These are the first pictures of the facelifted Mercedes-Benz B-class, which is expected to go on sale at the end of this year following its debut at the Paris motor show in October.

This model was seen benchmark testing against the current B-class, as well as a seventh-generation Volkswagen Golf.

Although only a minor facelift, new styling details include new headlight graphics, a more prominent front grille and a refreshed front bumper, which can be seen in these pictures. New taillight graphics also appear at the rear of the B-class, alongside a new rear bumper and new exhaust designs.

No changes are expected in the B-class's engine line-up, meaning the new model will likely come with the same range of 1.4, 1.8 and 2.1-litre diesel options as the current car, alongside 1.6 and 2.0-litre petrols.

Those engines could be supplied with minor modifications to improve fuel economy and CO2 emissions. The cleanest version of the current B-class, the 180 CDi ECO, emits 98g/km of CO2 and returns 74.3mpg on a combined cycle.

While some reports suggest Mercedes could offer a hybrid variant of the B-class with a three-cylinder engine in the future, it's unlikely since the production version of the B-class Electric Drive has been confirmed as arriving early next year.

As well as the updated B-class, Mercedes has previously confirmed it will also introduce a facelifted version of the CLS this autumn.
