⚙️ Engine Specifications

Engine Options 2014:

Likely includes V8 gasoline engines (e.g., G550 with 5.5L V8, potentially G63 AMG with 5.5L V8 Bi-Turbo). Diesel options (e.g., G350 BlueTEC) may also be covered depending on market. Specific engine codes (e.g., M273, M157) would be detailed within the manual.

Horsepower Torque Range:

Typically ranging from 382 hp to over 536 hp and 400+ lb-ft of torque, depending on the specific engine variant. Exact figures are in the manual.

Injection Type:

Multi-point fuel injection (MPI) or direct injection (DI) depending on engine. Detailed fuel pressure and injector flow rates will be specified.

🔧 Transmission

Transmission Type:

Likely a 7-speed automatic transmission (7G-TRONIC PLUS) as standard for most variants, with manual transmission availability being extremely rare or non-existent for this generation and model year.

Transmission Features:

Includes detailed procedures for transmission fluid and filter changes, torque converter servicing, transmission control module (TCM) diagnostics, and shift solenoid testing.

📐 Dimensions

Body Style:

Body-on-frame SUV, typically 4-door wagon configuration. Specific lengths, widths, and heights vary slightly by sub-model but are fundamentally consistent with the W463 platform's robust design.

Curb Weight Range:

Typically in the range of 5,000 - 5,500 lbs (2,270 - 2,500 kg) depending on engine and equipment. Gross Vehicle Weight Rating (GVWR) will also be specified.

🛡️ Safety Features

Crash Test Performance:

While specific NHTSA or IIHS ratings for this exact year and model are not universally published due to its niche status and previous generation underpinnings, the manual will detail safety systems and their operation.

Typically every 10,000 miles or 12 months, whichever comes first, using synthetic oil. Specific recommendations will be in the manual.

Transmission Service Interval:

Often recommended around 60,000 miles, though severe driving conditions may necessitate earlier service. Fluid type and procedure are critical.

Engine Oil Specification:

Likely requires a full synthetic engine oil meeting Mercedes-Benz specifications such as MB-Approval 229.5 or 229.51, with viscosity grades like 0W-40 or 5W-40. Exact specs are in the manual.

Transmission Fluid Specification:

Specific Mercedes-Benz approved ATF, such as MB-Approval 236.14 (for 7G-TRONIC). Critical to use the correct fluid to avoid transmission damage.

Coolant Specification:

Ethylene glycol-based coolant meeting Mercedes-Benz specification MB 325.0 or MB 326.0, typically a blue or green color.

Common Wear Items:

As with many luxury SUVs of this age, potential areas for wear include suspension bushings, ball joints, various electronic sensors, and the transmission control unit. The manual provides diagnostic guidance for these.

📚 Vehicle History

Mercedes-Benz Offroad Legacy:

The G-Class (Geländewagen) has a long lineage dating back to the 1970s, originally designed as a rugged, military-grade off-road vehicle. Its transition to a luxury icon began with the W463 generation.

W463 Generation Characteristics:

The W463, introduced in 1990, marked a significant shift towards luxury with a more refined interior, independent front suspension (on most models, though retaining robust solid axles in other areas for off-road prowess), and the introduction of more powerful engines and advanced features. The 2014 model represents a mature iteration of this platform before its complete redesign.

Manufacturing Location:

Graz, Austria, by Magna Steyr under contract for Mercedes-Benz.

🏆 Awards & Recognition

Offroad Capability Accolades:

While specific awards for the 2014 model year might be scarce, the G-Class consistently receives recognition for its unparalleled off-road prowess and durability, often favored by enthusiasts and in specialized automotive publications.
