2021 Mercedes-Benz GLB vs 2020 Cadillac XT6

The 2020 Cadillac XT6 presented a clean and crisp exterior, embodying the best of modern Cadillac design. Its long, boxy shape was cleverly disguised under smooth body panels and limited creases, creating a slimming effect. The XT6 avoided flashy chrome and oversized elements, opting instead for satin-painted silver accents and a medium-sized silver mesh grille. Its thin LED headlights and vertical running lamps added a touch of flair, while the overall design maintained a sense of restraint and taste. However, the interior did not match the exterior's sophistication. Despite having soft leather and gold-tinted carbon fiber trim, the seats lacked support and style, and the use of cheap vinyl detracted from the luxury feel. The interior seemed outdated compared to competitors, with small screens and ordinary color combinations.

In contrast, the 2021 Mercedes-Benz GLB was a modern stunner, both inside and out. Its exterior was attractive and athletic, with a healthy ground clearance that added to its robust stance. The GLB's interior was a highlight, featuring a striking repetition of round shapes across the dash and polished metal details in the HVAC vents, evoking an aerospace vibe. The single panel housing the virtual instrument cluster and infotainment screen was elegant, and the cabin boasted excellent fit and finish. The steering wheel, with its perforated leather grips, added to the luxurious feel, making the GLB's interior a standout in its class.

The 2020 Cadillac XT6 was powered by a 3.6-liter V6 engine, delivering 310 horsepower and 271 pound-feet of torque.

The 9-speed automatic transmission provided quick shifts, and the AWD model with adaptive dampers offered a balanced and controlled ride.
