2021 Mercedes-Benz GLB vs 2021 Mercedes-Benz GLC

Serving Milwaukee, WI

For today’s crossover SUV shoppers in the Milwaukee area who crave exceptional performance and premium features in a new vehicle, the Mercedes-Benz lineup deserves undivided attention. At Mercedes-Benz of Milwaukee North, the GLB and the GLC crossovers hold significant appeal for drivers in the market for a smaller model. As close siblings in the 2021 lineup, the GLB and the GLC crossovers are beautifully similar and have exciting differences as well.


The 2021 GLB is a first-generation model in the subcompact crossover class. The primary engine for the GLB is an I-4, 2.0-liter turbo engine that puts out 221 horsepower. Acceleration up to 60 miles per hour occurs in 6.9 seconds. Both rear-wheel and 4MATIC® all-wheel drive drivetrains are offered. The GLC crossover has a comparable engine, and it draws 255 horsepower from the engine with its unique mechanical features. Notably, the GLC crossover is also available with a hybrid powertrain that puts out 315 net horsepower.


The GLB and the GLC are stunningly different from a design perspective. The GLB has a confident, cube-like stance with skid plates at the front and rear, raised roof rails, and sculpted sides. The GLC, on the other hand, has modest curvature through the roofline and comes with integrated roof rails. These two models have a comparable grille and LED headlight designs, but the GLC’s nose is squared off for individuality.


For the 2021 model year, the GLB and the GLC crossovers have modern style across their interiors, but they deliver their style in unique ways. For example, the GLB has contiguous display screens combined with rounded air vents and ambient lighting to produce a premium feel throughout the cabin. The 2021 GLC, on the other hand, has a different center stack with woodgrain accents that flow up to a floating center stack. The infotainment system’s screen is separated from the driver’s digital gauges. Both vehicles are loaded with high-end materials, smart device integration, assistive driver’s aids, and more.
