Highlights

The 2021 Mercedes-Benz GLS is a showcase of Mercedes-Benz's engineering prowess and commitment to luxury.

• Engine Options: The GLS offers robust and sophisticated powertrain options:

  • GLS 450 4MATIC: Powered by a 3.0-liter inline-6 turbocharged engine with EQ Boost, producing a combined 362 horsepower and 369 lb-ft of torque. The EQ Boost system provides a temporary 21 horsepower and 184 lb-ft of torque, offering smoother acceleration and improved fuel efficiency.
  • GLS 580 4MATIC: Features a more potent 4.0-liter V8 biturbo engine with EQ Boost, delivering a substantial 483 horsepower and 516 lb-ft of torque. The EQ Boost here offers a temporary 21 horsepower and 184 lb-ft of torque.
  • AMG GLS 63 4MATIC+: This high-performance variant boasts a handcrafted AMG 4.0-liter V8 biturbo engine with EQ Boost, generating a formidable 603 horsepower and 627 lb-ft of torque, with EQ Boost adding an extra 21 horsepower and 184 lb-ft.

• Advanced Safety Features: Mercedes-Benz equips the GLS with a comprehensive suite of driver-assistance systems designed to enhance safety and reduce driver fatigue:

  • Active Brake Assist: Utilizes radar and camera systems to detect potential collisions with vehicles, pedestrians, or cyclists. It can warn the driver and, if necessary, automatically apply the brakes to prevent or mitigate a crash.
  • Active Distance Assist DISTRONIC: An adaptive cruise control system that maintains a set distance from the vehicle ahead. It can also assist with steering by keeping the vehicle centered in its lane.
  • PRE-SAFE® System: A proactive safety system that prepares the vehicle and its occupants in the moments before an unavoidable accident. This can include tightening seatbelts, closing windows, and adjusting seats.
  • Active Steering Assist: Works in conjunction with DISTRONIC to provide steering assistance, helping to keep the vehicle centered in its lane and navigate curves.
  • Blind Spot Assist: Monitors the blind spots on either side of the vehicle and can warn the driver if another vehicle is detected.
  • Lane Keeping Assist: Detects unintentional lane departures and can gently steer the vehicle back into its lane.

• Trim Levels: The 2021 GLS lineup offers distinct levels of luxury and performance:

  • GLS 450 4MATIC: The entry-level offering, still incredibly well-equipped with luxurious appointments and potent performance.
  • GLS 580 4MATIC: Steps up the luxury and performance with a V8 engine and a more extensive list of standard features.
  • AMG GLS 63 4MATIC+: The ultimate expression of the GLS, combining unparalleled luxury with exhilarating AMG-tuned performance.

• Notable Aspects:

  • Spacious and Versatile Interior: The GLS boasts three rows of seating as standard, with power-folding second-row seats for easy access to the third row. The cabin is exceptionally quiet and features premium materials throughout.
  • MBUX Infotainment System: The intuitive and visually stunning Mercedes-Benz User Experience (MBUX) system features a large touchscreen display, natural voice control ("Hey Mercedes"), and augmented reality navigation for a seamless and connected experience.
  • E-ACTIVE BODY CONTROL (Optional): This advanced active suspension system analyzes the road ahead and adjusts each wheel individually to counteract bumps, dips, and body roll, providing an incredibly smooth and composed ride.
  • Off-Road Engineering Package (Optional on GLS 450 and GLS 580): For those who venture off the beaten path, this package includes an underbody protection panel and a specialized driving mode for improved off-road capability.

What to Expect

Owning a 2021 Mercedes-Benz GLS is generally a rewarding experience characterized by luxury, comfort, and a sense of occasion.

• Typical Ownership Experience: The GLS is designed for effortless long-distance cruising and comfortable daily driving. The cabin is a sanctuary, insulated from road noise and external distractions. The advanced driver-assistance systems contribute to a relaxed driving experience, especially in traffic. Cargo space is ample, and the flexible seating arrangements make it a practical choice for families. The MBUX system, while feature-rich, can have a slight learning curve for those unfamiliar with Mercedes-Benz interfaces.

• Maintenance: As a luxury vehicle, the GLS typically requires scheduled maintenance at authorized Mercedes-Benz dealerships or reputable independent specialists. Routine services include oil changes, filter replacements, tire rotations, and brake inspections. While regular maintenance is crucial for longevity, Mercedes-Benz vehicles generally have excellent build quality. However, repairs outside of the warranty period can be more costly than those for mainstream brands.

• Insurance: Insurance premiums for a 2021 Mercedes-Benz GLS are likely to be higher than for less expensive or less powerful vehicles. This is due to the vehicle's luxury status, advanced technology, higher repair costs, and potentially higher performance figures, especially for the AMG GLS 63. Factors such as your driving record, location, age, and chosen coverage levels will significantly impact the final cost. It is advisable to obtain quotes from multiple insurance providers to find the best coverage at a competitive rate.

Potential Considerations

While the 2021 Mercedes-Benz GLS excels in many areas, there are a few aspects potential buyers should be aware of.

• Fuel Economy: The powerful engines, particularly the V8 and AMG variants, can be thirsty. While EQ Boost offers some improvement, the GLS is not a fuel-sipper, and buyers should anticipate higher fuel costs, especially with frequent city driving.

• Complexity of Technology: The extensive array of advanced technology, while offering immense benefits, can also lead to a steeper learning curve for some users. Mastering all the features of the MBUX system and the various driver-assistance aids may require some patience and dedicated exploration.

• Ride Quality (without E-ACTIVE BODY CONTROL): While the standard suspension is refined, opting for the E-ACTIVE BODY CONTROL can significantly enhance ride comfort. Without this optional feature, while still excellent, some may find the ride slightly firmer than expected for a vehicle in this class, particularly over rougher surfaces.

• Third-Row Space: While the GLS offers a third row, it's best suited for children or shorter adults on longer journeys. For full-size adults, the space can feel a bit confined, especially compared to some competitors with slightly more generous third-row dimensions.

Overall Summary

The 2021 Mercedes-Benz GLS is a compelling choice for those seeking a luxurious, spacious, and technologically advanced full-size SUV. It offers a refined driving experience, a supremely comfortable and quiet cabin, and a wealth of innovative features that cater to the needs of modern families and discerning drivers. While fuel consumption and the complexity of its technology are points to consider, its exceptional build quality, premium appointments, and robust safety systems solidify its position as a benchmark in the luxury SUV segment. The GLS delivers on its promise of S-Class levels of comfort and sophistication, making it a highly desirable vehicle for those who demand the best.
