⚙️ Engine Specifications

Engine Variants:

The W463 platform has featured a range of gasoline and diesel engines, including V6, V8, and V12 configurations. Specific engine codes and displacements would vary by year and market (e.g., M113, OM642).

General Performance:

Engines are typically tuned for robust torque delivery for off-road use and strong acceleration, with varying horsepower and torque outputs depending on the specific engine.

Fuel Delivery:

Fuel injection systems (e.g., Bosch Motronic) are standard across the W463 range.

🔧 Transmission

Transmission Type:

Primarily automatic transmissions (e.g., 7G-TRONIC, 5-speed automatic) are standard on most W463 models.

Optional Transmission:

While less common in later W463 generations, earlier models might have had manual transmission options, though the focus for this manual is likely on the prevalent automatic transmissions.

Drivetrain:

Permanent all-wheel drive (4MATIC) with locking differentials for enhanced off-road capability is a hallmark of the G-Class.
