The Mercedes GLS has been spied virtually undisguised ahead of a possible debut at the Los Angeles Auto Show.

The Mercedes GLS has been spied virtually undisguised ahead of a possible debut at the Los Angeles Auto Show.

Essentially a facelifted version of the GL, the GLS features a new front fascia with a revised grille and modified air intakes.  The crossover also has a new rear bumper and restyled lighting units.

Our spies couldn't get close enough to snap interior photos but the cabin is expected to echo the GLE.  This means we can likely expect a new multi-function steering wheel, a freestanding infotainment system and updated upholstery.

Engine options are largely expected to carryover so expect to see a handful of familiar petrol and diesel units.
