All-New Mercedes-Benz GLB Promises a True “Welcome Home” Winter Comfort
SHERIDAN, WYOMING – December 8, 2025 – Mercedes-Benz is giving fans a first real peek at the all-new GLB ahead of its world premiere on December 8, 2025, and the message is clear: this compact SUV wants to feel like a warm, confident refuge even when winter is at its worst. Before it steps into the spotlight, engineers are pushing the new GLB through intense cold-weather testing at the Mercedes Technology Center in Sindelfingen, using high-tech climatic wind tunnels that can mimic deep-freeze temperatures and brutal blizzard conditions.
Winter Confidence Starts with Realistic Extremes
Cold weather can expose weaknesses quickly—traction, visibility, cabin comfort, even small things like air inlets and wiper performance. That’s why Mercedes-Benz is running the all-new GLB through controlled tests that simulate conditions as low as -40 degrees Fahrenheit, plus high-speed snowstorms where flakes can hit the vehicle at up to 124 mph.
