Land Rover Engine 4.0 vs 4.6: What’s The Difference?
Confused between Land Rover 4.0 and 4.6 engines? Well, they are excellent engine options. But due to their similarities, it can be hard to pick one from them.
So, when it comes to Land Rover engine 4.0 vs 4.6: what’s the difference?
Compared to the 4.0 engine, the Land Rover 4.6 engine has a larger displacement, resulting in more power, horsepower, and torque. These 4.6 engines provide improved performance and towing capacity for larger and heavier Range Rovers. Nevertheless, the 4.0 engine offers adequate performance at a lower rate for smaller Range Rovers. So, if you don’t need extra power, the 4.0 engine may be more cost-effective.
In the next chapters, we will be discussing more about their differences.
Land Rover Engine 4.0 vs 4.6: What’s The Difference?
The 4.0 and 4.6 engines are quite similar but still, they still have a couple of differences that can be a deal breaker. These differences are similar to the differences between LR4 and LR3. Let’s take a look at their basic differences-
| Comparing Factors | Land Rover 4.0 Engine | Land Rover 4.6 Engine |
| Displacement | 4.0 liters | 4.6 liters |
| Power Output | Approximately 188 hp | Approximately 222 hp |
| Torque | Approximately 250 lb-ft | Approximately 300 lb-ft |
| Acceleration | Moderate | Slightly better |
| Application | Land Rover Discovery Series 2 | Land Rover Range Rover (P38) |
| Parent Company | BMW (until 2002) | Ford Motor Company |
| Cost | Less than 4.6 | More than 4.0 |
Now, let’s see how the differences may impact your choices.
Displacement:
In terms of raw power potential, the 4.6 engine is considered better due to its larger displacement. With more air and fuel available for combustion, it can produce greater power output
A larger displacement generally allows for more air and fuel mixture to be drawn into the cylinders during the intake stroke. As a result, you get an increase in power potential.
The larger internal volume in the 4.6 engine allows for more efficient combustion and potentially higher power output compared to the 4.0 engine.
Winner: 4.6 for more displacement
Power Output:
The 4.6 engine is superior to the 4.0 engine. With approximately 222 horsepower compared to 188 horsepower, the 4.6 engine offers a noticeable increase in performance and acceleration.
A modified internal component, improved engine management, and optimized intake and exhaust systems are also included in the 4.6 engine.
The difference in power output between the Land Rover 4.0 and 4.6 engines can be attributed to several factors. The larger displacement of the 4.6 engine allows for a greater volume of air and fuel mixture to be combusted. This results in more power being generated.
The additional horsepower allows the vehicle to accelerate more quickly. The increased power can also result in a higher top speed. Moreover, the higher power output can enhance the engine’s ability to handle heavy loads.
Winner: 4.6 for higher power output
Torque:
The 4.0 engine generates approximately 250 lb-ft of torque, whereas the 4.6 engine produces approximately 300 lb-ft of torque.
The increased torque of the 4.6 engine provides several benefits. Firstly, it enhances low-end power. This allows the vehicle to accelerate more effortlessly from a standstill or at low speeds.
Furthermore, the greater torque output of the 4.6 engine contributes to improved off-road performance. With higher torque, the engine can deliver more power to the wheels, enabling better traction.
Winner: 4.6 for higher torque output
Application:
The Land Rover 4.0 engine was commonly used in the Land Rover Discovery Series 2.
The Land Rover 4.6 engine was found in the Land Rover Range Rover (P38).
The Land Rover Discovery Series 2, which featured the 4.0 engine, was designed as a mid-size luxury SUV. It offered a balance between off-road capability and on-road comfort. The 4.0 engine, with its moderate power output, was suitable for Discovery’s intended purpose.
The engine provided adequate power for typical driving situations, both on and off the road, without being excessive. It offered a good combination of performance, fuel efficiency, and reliability for Discovery’s target audience.
On the other hand, the Land Rover Range Rover (P38) was a full-size luxury SUV aimed at a more upscale market segment. The Range Rover is known for its refined interior, advanced features, and superior off-road capability.
The 4.6 engine, with its increased power and torque compared to the 4.0 engine, provided a boost in performance for the larger and heavier Range Rover. The additional power and torque helped deliver better acceleration and improved towing capacity.
But for the utilize the full potential of its towing capacity, you will need to install Land Rover recovery points.
Winner: Tie
Cost:
Land Rover 4.6 engine costs more than 4.0, which is justified because it gives you more engine displacement, which means more power. The Land Rover 4.0 costs around $6000 and 4.6 costs $7800.
So, if you do not really need the extra power 4.6 provides, you probably should get the 4.0 instead.
Winner: 4.6 is more cost-efficient.
Land Rover Engine 4.0 vs 4.6: Which One Is Better For You?
The Land Rover 4.6 engine offers a larger displacement, higher power output, and greater torque compared to the 4.0 engine. But it also comes at a higher cost. If you truly require the extra power and performance provided by the 4.6 engine, it may be worth the investment.
However, if the additional power is not a necessity for your needs, the 4.0 engine can still offer adequate performance while being more cost-effective.
Ultimately, the choice between the two engines depends on your specific requirements and budget.
No matter which engine you choose, proper maintenance is key. Or, you will face some serious Land Rover engine problems.
Frequently Asked Questions (FAQs):
