2022 Mercedes-Benz GLB vs 2023 Acura MDX

The 2022 Mercedes-Benz GLB was positioned between the GLA and GLC in the automaker's SUV lineup, available in GLB250 and AMG GLB35 specifications. The GLB250 offered front-wheel drive (FWD) or 4Matic all-wheel drive (AWD), while the AMG GLB35 boasted a more powerful drivetrain with a sophisticated AWD system. Changes for the year included satellite radio in the Premium Package and a new AMG Night Package Plus with black grille louvers and badges. The AMG GLB35 also introduced a new Rose Gold paint color. Starting at $38,600 for the GLB250, the AMG GLB35 began at $51,000, with our test model totaling $57,250 with options. The GLB's design was polarizing, with a steep windshield angle and short overhangs, but the 21-inch wheels added style. Inside, the cabin was a visual treat, though the controls required acclimation. Quality was evident, but road noise was pronounced, especially with the larger wheels.

The 2023 Acura MDX offered standard and Type S versions, each with trim packages enhancing equipment levels. The standard MDX came with base, Technology, A-Spec, and Advance packages, while the Type S was available in standard or Advance trim. Prices ranged from $49,550 to $73,200, plus a $1,195 destination charge. Our test vehicle, a Type S Advance, featured Apex Blue Pearl paint and an Orchid interior, with an MSRP of $74,995. The fourth-generation MDX was the first Acura SUV to wear the Type S badge, with subtle styling cues and 21-inch wheels. The interior featured perforated Milano leather, aluminum trim, and a Sport Appearance package. The Type S Advance added open-pore wood and a leather-wrapped dashboard. While the MDX Type S was appealing, the body design could appear dented from certain angles, and the gloss black plastic on the dashboard made controls challenging to use. The electronic transmission switchgear was also confusing, detracting from the overall luxury experience.

The 2022 Mercedes-Benz GLB featured a turbocharged 2.0-liter four-cylinder engine in both versions. The AMG GLB35 was enhanced to produce 302 horsepower and 295 pound-feet of torque, outperforming the GLB250's engine by 81 hp and 37 lb-ft. The AMG GLB35 included an AMG SpeedShift eight-speed dual-clutch automatic transmission, AMG Performance variable 4Matic AWD, and an AMG Sport Exhaust system. It accelerated to 60 mph in 5.1 seconds, 1.8 seconds faster than the GLB250. The AMG GLB35's EPA fuel economy rating was 22 mpg combined, with our test averaging 21.8 mpg. The AMG High-Performance Braking System and AMG Ride Control adaptive damping sport suspension were standard, emphasizing performance over comfort. The AMG GLB35 excelled on twisty roads, offering a thrilling driving experience, but its firm ride and loud road noise made it less suitable for daily driving.

The 2023 Acura MDX Type S was distinguished by its turbocharged 3.0-liter V6 engine, generating 355 horsepower and 354 pound-feet of torque, surpassing the standard 3.5-liter V6 by 65 hp and 87 lb-ft. The Type S used a 10-speed automatic transmission with paddle shifters and Acura's Super Handling All-Wheel Drive (SH-AWD). The Integrated Dynamics System offered multiple driving modes, including an exclusive Lift mode for increased ground clearance. Despite performance enhancements, the MDX Type S struggled to deliver a cohesive driving experience. The transmission was indecisive, and the ride lacked compliance. The engine's power increase was modest, and fuel economy was poor, averaging 16.9 mpg on the evaluation route. The MDX Type S was more agreeable in Normal mode but faltered in Sport and Sport+ modes, with brake pedal response and tire squeal issues. Overall, the MDX Type S lacked the cohesion and predictability expected from a performance model.

The 2022 Mercedes-Benz GLB catered to urbanites needing a roomy yet compact SUV, offering an optional third-row seat for children. Standard features included dual-zone automatic climate control and eight-way power-adjustable front seats with simulated leather upholstery. Heated and ventilated front seats, a heated steering wheel, and a panoramic sunroof were available. The GLB provided easy access and a tall seating position with excellent visibility. The rear doors opened wide, accommodating two adults comfortably, though the optional third-row seat reduced cargo space. The GLB's power rear liftgate revealed a 22 cubic-foot cargo area, expandable to 62 cubic feet with the second-row seat folded.

The 2023 Acura MDX offered three rows of seats with flexible second-row configurations and ample cargo space. Our test vehicle featured triple-zone climate control, 16-way power-adjustable front seats with heating, ventilation, and massage, and quilted leather upholstery. The MDX's seats were comfortable but lacked the performance-oriented support expected in the Type S. Seven-passenger seating was standard, with a removable second-row center section for pass-through access. The third row was best suited for children. The MDX's interior prioritized style over storage, with limited space in the center console. The power liftgate revealed a spacious cargo area with underfloor storage, accommodating luggage and more. The MDX offered 18.1 cubic feet of cargo space behind the third row, expandable to 71.4 cubic feet with both rear rows folded.

The 2022 Mercedes-Benz GLB featured the Mercedes Benz User Experience (MBUX) infotainment system, with a 10.25-inch digital gauge cluster and touchscreen. Standard features included Bluetooth, Apple CarPlay, Android Auto, and Mercedes Me connected services. The Premium Package added satellite radio, while the Multimedia Package included a navigation system with augmented reality. Optional upgrades included wireless charging, a Burmester audio system, WiFi, and gesture control. MBUX was user-friendly, with natural voice recognition and a digital assistant. The navigation system's augmented reality technology was particularly impressive.

The 2023 Acura MDX's Digital Precision Cockpit included a 12.3-inch digital instrumentation panel and infotainment display. The infotainment system used a True Touchpad Interface (TTI) on the center console, accompanied by a wrist rest, volume knob, and tuning switch. The TTI design was innovative but added complexity and reduced storage space. The MDX featured wireless Apple CarPlay, Android Auto, and Amazon Alexa Built-In. Additional features included SiriusXM, navigation, and AcuraLink connected services with a complimentary three-year subscription. The MDX offered several sound systems, with the top-tier ELS Studio 3D audio system delivering exceptional sound quality. The Advance package added a 10.5-inch head-up display, though the traffic sign recognition system occasionally misread signs.

The 2022 Mercedes-Benz GLB lacked the optional Driver Assistance Package, which included 12 advanced safety features. The test vehicle was missing evasive steering assist, lane-departure warning, lane-keeping assistance, and rear cross-traffic warning. However, it included Active Brake Assist, blind-spot monitoring, and Mercedes-Benz emergency call service. Crash-test ratings for the GLB were unavailable.

The 2023 Acura MDX featured Acura Watch, a suite of driving assistance and collision avoidance systems. Standard features included forward-collision warning, automatic emergency braking, lane-departure warning, lane-keeping assist, lane-centering assist, adaptive cruise control, and Traffic Jam Assist. The MDX also had blind-spot monitoring and rear cross-traffic alert. Certain trims added parking sensors, low-speed automatic braking, and a surround-view camera. The MDX received good crash-test ratings, earning a Top Safety Pick+ from the IIHS and a five-star rating from the NHTSA.
