This article delves into the detailed specifications of these models, providing a comprehensive overview for automotive enthusiasts and potential owners interested in the Benz Gl 2010 series.
2010 Benz GL Model Comparison: GL350 BlueTEC, GL450 4MATIC, and GL550 4MATIC
Mercedes-Benz designed the 2010 GL-Class as a four-door, seven-passenger luxury sport utility vehicle across all its trims. All models share a robust steel unibody chassis, ensuring durability and passenger safety. While visually similar, the core differences lie in their powertrains and performance metrics, which we will explore in detail.
Engine and Performance
The heart of each Benz GL 2010 model is its engine, each offering a unique balance of power and efficiency.
-
GL350 BlueTEC: This model is equipped with a 72-degree V6 diesel engine. The engine block and head are constructed from aluminum, featuring a single overhead camshaft per cylinder bank and four valves per cylinder. With a displacement of 2,987 cc, it delivers 210 horsepower at 3,800 rpm and a substantial 400 lb-ft of torque between 1,600 and 2,800 rpm. The turbocharger and intercooler, combined with piezoelectric injectors, contribute to its efficiency and responsiveness.

GL450 4MATIC: Stepping up, the GL450 boasts a 90-degree V8 gasoline engine, also with an aluminum block and head and four valves per cylinder. This engine utilizes a double overhead camshaft per cylinder bank and has a larger displacement of 4,663 cc. It produces 335 horsepower at 6,000 rpm and 339 lb-ft of torque between 2,700 and 5,000 rpm. The two-stage resonance intake manifold and tumble flaps enhance its performance across the rev range.
-
GL550 4MATIC: The pinnacle of the 2010 GL range is the GL550, featuring a more potent 90-degree V8 gasoline engine. Sharing the aluminum block and head and valvetrain configuration with the GL450, the GL550’s engine displaces 5,461 cc. This larger engine generates 382 horsepower at 6,000 rpm and 391 lb-ft of torque between 2,800 and 4,800 rpm. Like the GL450, it also features a two-stage resonance intake manifold, optimizing power delivery.
All engine variants in the Benz GL 2010 lineup are designed for robust performance and are paired with a seven-speed automatic transmission.
Transmission and Drivetrain
The 2010 Benz GL models utilize a seven-speed automatic transmission across the range, featuring Direct Select shift controls for smooth and responsive gear changes. The gear ratios are identical for all three models, ensuring consistent driving dynamics:
| Gear | Ratio |
|---|---|
| 1 | 4.38:1 |
| 2 | 2.86:1 |
| 3 | 1.92:1 |
| 4 | 1.37:1 |
| 5 | 1.00:1 |
| 6 | 0.82:1 |
| 7 | 0.73:1 |
| R | -3.42:1 |
| R2 | -2.23:1 |
The GL450 4MATIC and GL550 4MATIC share a final drive ratio of 3.70:1, while the GL350 BlueTEC has a slightly different final drive of 3.45:1, likely tuned for the diesel engine’s characteristics. All models feature ESP stability control and 4MATIC All-Wheel Drive with 4ETS traction control, employing brake and throttle intervention for enhanced stability and grip in varied driving conditions.
Suspension, Steering, and Brakes
The 2010 Benz GL prioritizes ride comfort and handling with its sophisticated suspension, steering, and braking systems.
Each model is equipped with a four-wheel independent suspension system using Airmatic air suspension. The front suspension is a double control arm setup with air springs, gas shocks, and a stabilizer bar. The rear utilizes a four-link configuration, also with air springs, gas shocks, and a stabilizer bar. This setup provides a comfortable ride while maintaining composed handling.
Steering across the Benz GL 2010 range is speed-sensitive power-assisted rack-and-pinion, offering a balance of ease at low speeds and precision at higher speeds. The turning radius is consistent at 39.7 feet, and the steering ratio is 18.6:1 for all models, requiring 3.62 turns lock-to-lock.
Braking is handled by hydraulic power-assisted 4-wheel vented discs with four-channel ABS anti-lock, Brake Assist, and electronic brake proportioning. The front disc diameter is 14.7 inches (375 mm) ventilated, and the rear disc diameter is 13.0 inches (330 mm) ventilated across all models. Front disc thickness is 1.26 inches (32 mm), and rear disc thickness is 0.87 inches (22 mm) for consistent and reliable stopping power.
