M, GL up game with smart 4WD

Mercedes aims to tighten its grip on the UK market by boosting the number of cars available with its advanced 4-Matic four-wheel drive.

Of the 48 models with the improved set-up, Britain will get 16; these include the M-Class and GL-Class off-roaders. But the firm has opted not to bring the C, E and S-Class saloon versions here.
