With the Concept GLB, Mercedes-Benz shows what SUV ideas on the company's compact car platform might also be realised alongside the GLA as a sporty all-rounder. While the latter promises progressive driving enjoyment with its coupé-like lines, the Concept GLB places the emphasis on spaciousness and robustness.
We asked ourselves whether there is still space between the GLA and GLC in our successful SUV range. The Concept GLB is the answer to this question. With it we are demonstrating the creative ideas we have for this segment, too. The Concept GLB is a durable and practical SUV with nonetheless compact dimensions.
SUV genes skilfully brought to the fore: Exterior design
The Mercedes-Benz Concept GLB has a distinctive presence in the world of compact SUVs with its muscular proportions. The clear, surface-accentuated contours with reduced lines and precise joints convey effortless superiority and modernity. The upright front section with its striking MULTIBEAM LED headlamps is clear evidence of off-road genes, as are the short overhangs at the front and rear. The long wheelbase and the functional greenhouse are the decisive factors providing generous spaciousness for up to seven occupants.
The muscular and sensuously contoured vehicle shoulder dominates the side view, an effect reinforced by the rising waistline. The contiguous doors improve ease of access and keep the door apertures free of soiling. All-round protective claddings divide the overall proportions and emphasise the vehicle's off-road character.
The harmonious colour concept has exterior paintwork in designo cashmere white magno with high-gloss black mounted parts (e.g. the claddings or integrated roof box) as a contrast, plus discreet orange highlights in the radiator grille and as lettering on the outside mirror housings.
The chrome underguard at the front with integral air inlets in a stainless steel look emphasises the off-road qualities. The rear underguard echoes this theme, creating a balanced overall picture.
High-quality finish and very spacious: the interior
In design terms the interior of the Concept GLB reveals its membership of the new Mercedes-Benz compact car family, but as a showcar and SUV it has a special leather features and special trim elements. And for the first time in a compact model by Mercedes-Benz, a third seat row with two additional single seats that can be recessed flush into the load compartment floor to increase load capacity. These seats are far more than emergency seats, and offer comfortable seating for two medium-sized occupants.
Powertrain: Four-cylinder turbo with 165 kW/224 hp
The Concept GLB is powered by the M 260 four-cylinder petrol engine combined with an 8G-DCT dual clutch transmission, with a maximum output of 165 kW/224 hp and peak torque of 350 Nm. The engine block of diecast aluminium with cast iron cylinder liners has CONICSHAPE® technology, which is also known in-house as "trumpet-honing". To further minimise piston friction and lower fuel consumption, the cylinder bore is widened at the lower end of the cylinder liners. The resulting, conical shape resembles the mouth of a trumpet.
An innovative low-friction oil and optimised piston rings also reduce friction losses. To take account of the higher specific output, the pistons themselves feature cooling ducts. This also ensures more efficient combustion. The balance shafts for smooth engine-running are located in the lower section of the crankcase. To enhance comfort even further, there is a centrifugal pendulum damper in the powertrain.
Also in the aluminium four-valve cylinder head is CAMTRONIC, a variable valve timing system that allows two-stage adjustment of the valve lift on the intake side of the valve assembly. In the partial-load range, this variable valve lift adjustment allows less air to be fed to the combustion chamber with a smaller valve lift, which leads to lower gas cycle losses. In higher load ranges the system switches to the higher valve lift to achieve the engine's full power delivery.
