The Affalterbach firm is developing two four-wheel-drive versions of the GLB, in both 35 4Matic and 45 4Matic trim. The 35 version, which will feature the same 302bhp 2.0-litre mild hybrid petrol engine found in the A35 hot hatch, is set to be revealed at Frankfurt, with sales starting later this year.
The Mercedes-AMG GLB has previously been spied undergoing development work in both variants. It is differentiated from standard versions by its reduced ride height, larger brake discs, multi-pot calipers and four tailpipes, as opposed to the twin-exit arrangement of the less powerful GLB 35 4Matic prototypes we’ve seen previously.
The GLB 45, due on sale next year to rival the Audi RS Q3, is among a number of new Mercedes-AMG models set to run a newly developed four-cylinder engine based on Mercedes’ turbocharged 2.0-litre 'M260' unit.
Also due to appear in the A45 4Matic, CLA 45, CLA 45 Shooting Brake and GLA 45, the new powerplant is claimed to develop 382bhp in standard guise and 416bhp in a higher state of tune.
