⚙️ Engine Specifications

Engine Variants:

Likely covers both the 4.0L V8 (2005-2009) and the 4.4L V8 (2010 onwards) and potentially diesel variants depending on region (e.g., 2.7L TDV6, 3.0L TDV6). The 2010 model year specifically points to the introduction of the 4.4L V8 (BMW N62) and continued availability of the 2.7L TDV6 and 3.0L TDV6.

Displacement Gas:

4.4 liters (for the 2010 model year, BMW N62 engine)

Displacement Diesel:

2.7 liters or 3.0 liters (depending on market and specific engine code, Ford Lion V6 family)

Horsepower 4.4L V8:

Approx. 300 hp (at 5500 rpm)

Torque 4.4L V8:

Approx. 315 lb-ft (at 3750 rpm)

Fuel Type:

Unleaded Gasoline (for V8 models); Diesel (for TDV6 models)

Injection Type:

Electronic Fuel Injection (EFI) with sophisticated engine management systems.

🔧 Transmission

Transmission Type:

Automatic transmission is standard on most LR3 models, particularly in North America. The ZF 6-speed '6HP26' automatic is a prominent unit.

Transmission Type Manual:

While a manual transaxle is listed as covered, manual transmissions were rare or not offered on North American LR3 models. If offered, it would be a 6-speed manual.

Drivetrain:

Permanent Four-Wheel Drive (4WD) with sophisticated electronic traction control and center differential locking.

Gear Ratios:

Detailed gear ratios for both manual (if applicable) and automatic transmissions will be provided.

📐 Dimensions

Length:

Approx. 4,834 mm (190.3 in)

Width:

Approx. 2,002 mm (78.8 in)

Height:

Approx. 1,886 mm (74.3 in) (without roof rails or load)

Curb Weight:

Varies by engine and configuration, typically around 2,300-2,500 kg (5,000-5,500 lbs)

🛡️ Safety Features

NHTSA Rating:

Specific NHTSA ratings for the 2010 model year should be consulted, but the Discovery 3 generally performed well in its class for its era.

Active Safety:

Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), Emergency Brake Assist (EBA), Dynamic Stability Control (DSC), Traction Control System (TCS), Hill Descent Control (HDC), Terrain Response System.

Passive Safety:

Multiple airbags (front, side, curtain), crumple zones, reinforced chassis structure, seatbelt pre-tensioners.

💡 Technology Features

Infotainment System:

Features a premium audio system (e.g., Harman Kardon or Meridian), optional navigation system, and various connectivity options for its time.

Driver Assistance:

Advanced systems like Terrain Response (adjusts vehicle settings for different terrains), Hill Descent Control (HDC), and potentially adaptive cruise control on higher trims.

Connectivity Features:

Auxiliary input for audio, possibly Bluetooth connectivity for hands-free calling and audio streaming on later models or optional upgrades.

🔧 Maintenance

Oil Change Interval:

Typically every 15,000 miles (24,000 km) or 12 months, whichever comes first (consult manual for specific engine and oil type recommendations).

Transmission Fluid Interval:

Automatic transmission fluid changes are often recommended at higher mileage intervals (e.g., 60,000-100,000 miles) or under severe service conditions. Consult the manual for specific procedures and fluid types.

Engine Oil:

Specific viscosity grades (e.g., 5W-30 or 0W-30) and API/ACEA specifications, likely meeting Jaguar Land Rover STJLR.03.5004 for diesel or STJLR.51.5122 for petrol engines. The manual will detail precise requirements.

Coolant:

Ethylene Glycol-based antifreeze, typically orange or pink coolant meeting specific Land Rover specifications (e.g., LT121 or equivalent).

Brake Fluid:

DOT 3 or DOT 4 brake fluid, depending on the system requirements detailed in the manual.

Common Problems:

Potential issues include air suspension compressor failures, ECu module issues, swirl flap actuator problems (diesel engines), and sometimes water ingress into electrical components. The manual will provide diagnostic guidance for these and other common faults.

📚 Vehicle History

Heritage:

Land Rover has a long-standing reputation for producing capable off-road vehicles with a blend of luxury and ruggedness.

Production Period:

The Discovery 3 generation was produced from 2004 to 2009. The 2010 model year represents the transition to the Discovery 4 (LR4) in many markets, but if this manual specifically refers to a 2010 LR3, it might be for specific late-production or regional variants.

🏆 Awards & Recognition
