The Mercedes-Benz G-Class W465 features advanced transmission systems that complement its high-performance engines, providing smooth shifting, efficient power delivery, and versatility for various driving conditions. Below are the key transmission systems offered in the W465 G-Class:

1. 9G-TRONIC Automatic Transmission:

• Transmission Type: 9-speed automatic transmission (known as the 9G-TRONIC)
• Available on: G 500, G 350 d, G 400 d, and AMG G 63
• Overview: The 9G-TRONIC is Mercedes-Benz's highly advanced 9-speed automatic transmission system, designed to provide smooth, efficient shifting while optimizing engine performance. This transmission offers seamless gear changes for improved fuel efficiency and quick acceleration when required.
• Key Features:
  • Wide Gear Range: The 9 gears allow for a broader range of ratios, resulting in better performance, particularly at high speeds and when towing.
  • Improved Fuel Economy: The 9G-TRONIC transmission enables better fuel efficiency by keeping engine RPMs lower during highway cruising, reducing fuel consumption.
  • Smooth Shifting: The system ensures smooth and almost imperceptible gear changes, enhancing comfort during long drives or off-road maneuvers.
  • Off-Road Performance: The 9-speed system offers exceptional control, enabling the driver to select the most appropriate gear for demanding off-road conditions, from steep climbs to deep mud.

2. AMG SPEEDSHIFT TCT 9-speed Automatic Transmission:

• Transmission Type: 9-speed dual-clutch automatic (known as the AMG SPEEDSHIFT TCT)
• Available on: AMG G 63
• Overview: The AMG SPEEDSHIFT TCT is a more performance-oriented version of the 9-speed automatic transmission, designed for high-performance driving. It features a dual-clutch system that allows for faster gear shifts and more immediate power delivery, making it ideal for aggressive acceleration and precise control on both the road and track.
• Key Features:
  • Faster Gear Changes: The dual-clutch setup enables lightning-fast gear changes with little to no interruption in power delivery, resulting in improved acceleration and responsiveness.
  • Sporty Driving Modes: The AMG SPEEDSHIFT TCT transmission integrates with the AMG Dynamic Select driving modes (such as Sport and Sport+), allowing for more aggressive, precise shifts in performance modes. It also has a manual mode for drivers who want to take full control of gear selection.
  • Track Performance: The dual-clutch system is particularly well-suited for track days or high-speed driving, where rapid shifts are crucial for maintaining performance and handling.

3. Transfer Case and 4MATIC System:

• Transfer Case: The G-Class W465 comes with a permanent all-wheel drive system, managed by a low-range transfer case. This system distributes torque between the front and rear axles to improve traction in off-road conditions.
• 4MATIC: The 4MATIC system is integrated with the 9G-TRONIC and AMG SPEEDSHIFT TCT transmissions to provide torque distribution between the front and rear axles. This ensures that power is delivered to the wheels with the most grip, enhancing stability and performance in all conditions, whether on the highway or off-road.

4. Low-Range Gearbox:

• Low-Range Transfer Case: In off-road situations, the G-Class W465 can activate the low-range gearbox. This reduces the gear ratios for better control and power at low speeds, ideal for off-road tasks such as rock crawling, hill descents, or driving on steep inclines.
• The low-range gearbox is controlled manually via a switch or dial, depending on the specific model and configuration.

5. Driving Modes and Transmission Integration:

• The 9G-TRONIC and AMG SPEEDSHIFT TCT transmissions are tightly integrated with the Dynamic Select system in the G-Class. This allows the driver to switch between different driving modes (e.g., Comfort, Sport, Sport+, Eco, Individual) and adjust the transmission's behavior accordingly:
  • Comfort Mode: In this mode, the transmission shifts smoothly for a more relaxed and fuel-efficient driving experience.
  • Sport and Sport+ Modes: In these modes, the transmission holds gears longer, shifts more quickly, and enhances throttle response to improve driving performance.
  • Manual Mode: Both systems allow the driver to select gears manually (using paddle shifters or the gear lever), which provides greater control over acceleration and engine braking.

6. Off-Road Gear Selection and Stability:

• When driving off-road, the 9G-TRONIC transmission automatically adapts to different terrain types by providing smoother shifting at low speeds. This is particularly beneficial when driving on uneven or rocky surfaces.
• The G-Class W465 can also utilize hill descent control, hill-start assist, and lockable differentials to further enhance its off-road capabilities while maintaining control over the transmission.

Conclusion:

The G-Class W465 uses advanced 9G-TRONIC and AMG SPEEDSHIFT TCT transmissions to deliver a seamless driving experience, whether on smooth highways or rugged off-road terrain. The 9-speed automatic transmission ensures smooth shifts and improved fuel efficiency, while the AMG SPEEDSHIFT TCT offers fast, performance-oriented shifts for the AMG G 63. The integration with 4MATIC, the low-range transfer case, and driving modes enhances the G-Class’s versatility, making it capable of both high-performance on-road driving and exceptional off-road adventures.
