The 2020 Acura MDX presented itself as a well-designed crossover SUV, though its styling was not particularly groundbreaking or attention-grabbing. It blended seamlessly into its surroundings, neither embarrassing nor overly impressing its driver. The MDX featured Acura's signature Jewel Eye LED headlights, which added a touch of sophistication to its front end. The sleek, low-slung design of the three-row SUV, combined with flawless paint and chrome, contributed to its overall appeal. Inside, the MDX offered a modern and straightforward interior, highlighted by twin infotainment screens and a high-quality fit and finish that gave it a solid and well-built feel.
In contrast, the 2021 Mercedes-Benz GLB was a fresh addition to the Mercedes-Benz SUV lineup, boasting an attractive and athletic stance. Its design was characterized by a healthy ground clearance, which made it more forgiving on uneven roads. The GLB's interior was a modern marvel, with a striking repetition of round shapes across the dash and polished metal details that evoked an aerospace vibe. The single panel housing both the virtual instrument cluster and infotainment screen added elegance to the cabin. The GLB's fit and finish were of Mercedes-Benz's high standards, and the beefy steering wheel with perforated leather grips added to the driving experience.















The 2020 Acura MDX offered two powertrain options: a 3.5-liter V6 engine producing 290 horsepower and 267 pound-feet of torque, paired with a nine-speed automatic transmission, and a Sport Hybrid version with a 3.0-liter V6 engine and three electric motors, delivering a combined 321 horsepower and 289 pound-feet of torque. The MDX's Super-Handling All-Wheel Drive system (SH-AWD) enhanced its performance, providing nimble handling and torque-vectoring technology for improved cornering. The MDX's four-wheel independent suspension ensured a comfortable ride, making it a reliable companion for long journeys.
The 2021 Mercedes-Benz GLB came with a single engine choice: a turbocharged 2.0-liter inline four-cylinder engine producing 221 horsepower and 258 pound-feet of torque, mated to an eight-speed dual-clutch automatic transmission. The GLB's performance was decent, with a 0-60 mph time of 6.9 seconds and a top speed of 130 mph. The optional 4MATIC all-wheel drive improved handling and driving feel, especially on dry roads and during cornering. The GLB's Off-Road Engineering Package added features like hill-start assist and downhill speed regulation, making it suitable for light off-road adventures.
The 2020 Acura MDX offered a spacious interior with sliding and reclining second-row seats, making access to the third row easier. It provided 15.8 cubic feet of luggage space behind the third row, expandable to 90.9 cubic feet with the second and third rows folded flat. The MDX featured ample storage options, including a flexible center console and door pockets. Tri-zone climate control ensured comfort for all passengers, making it a stylish alternative to a minivan.

Cargo space varied depending on the configuration, with up to 62.0 cubic feet available in the two-row version. The third row was best suited for children or short trips. The GLB's front seats were highly adjustable and supportive, with available heated and ventilated options. Modern amenities like door pockets, map pockets, and cupholders met expectations for a luxury SUV.
