Performance Comparison
0-60 MPH Times
One of the key metrics for comparing engine performance is the 0-60 mph time. This measure gives a clear indication of how quickly a vehicle can accelerate from a standstill to highway speeds.
In real-world tests, the 7.3 Godzilla engine has shown respectable 0-60 mph times, typically in the range of 7.5 to 8 seconds, depending on the vehicle configuration and load. This makes it a strong performer for a gasoline engine, especially considering its size and power output.
On the other hand, the 6.7 Power Stroke diesel engine excels in low-end torque, which significantly boosts its acceleration. Vehicles equipped with this engine can achieve 0-60 mph times in the range of 7 to 7.5 seconds. While this may not seem drastically faster, the real advantage of the 6.7 Power Stroke lies in its ability to maintain strong acceleration even when towing heavy loads.
Power and Torque
When comparing power and torque, both engines have their strengths. The 7.3 Godzilla offers impressive horsepower, making it suitable for a variety of applications where high-revving power is needed. Its 430 hp at 5,500 rpm provides plenty of punch for most driving scenarios.
The 6.7 Power Stroke, however, is a torque monster. With 1,050 lb-ft of torque available at just 1,800 rpm, this engine is designed to handle the heaviest loads with ease. This massive torque output makes the 6.7 Power Stroke ideal for towing and hauling, where low-end power is crucial.
Towing and Hauling Capabilities
Towing Capacity
When it comes to towing, both engines have impressive capabilities, but the 6.7 Power Stroke stands out for its sheer towing power.
- 7.3 Godzilla: Up to 21,000 lbs
- 6.7 Power Stroke: Up to 37,000 lbs
This significant difference in towing capacity highlights the diesel engine’s advantage in heavy-duty applications. If you frequently tow large trailers, boats, or heavy equipment, the 6.7 Power Stroke is the clear winner.
Payload Capacity
Payload capacity refers to the weight a vehicle can carry in its bed, excluding any trailers or additional loads.
- 7.3 Godzilla: Up to 7,850 lbs
- 6.7 Power Stroke: Up to 6,180 lbs
While the 7.3 Godzilla has a higher payload capacity, the 6.7 Power Stroke’s lower figure is still very respectable, especially considering its superior towing capabilities.
Fuel Efficiency
7.3 Godzilla
The 7.3 Godzilla is relatively fuel-efficient for a large gasoline engine. Owners report highway fuel efficiency figures around 17 miles per gallon (mpg), which is quite good for a heavy-duty truck engine.
6.7 Power Stroke
The 6.7 Power Stroke diesel engine, while more powerful, also manages to deliver impressive fuel efficiency. Drivers often see highway figures around 20 mpg, making it a more economical choice for long-distance travel and heavy-duty use.
Durability and Maintenance
7.3 Godzilla
The 7.3 Godzilla is known for its robust construction and reliability. However, being a relatively new engine, long-term durability data is still emerging. Early indications suggest that it could follow in the footsteps of its predecessor, the 6.2L Boss, which has a reputation for reaching up to 300,000 miles with proper maintenance.
Common issues reported include faulty phasers and occasional oil and coolant leaks, but these are generally manageable with regular maintenance.
6.7 Power Stroke
The 6.7 Power Stroke has a well-established reputation for durability and longevity. Many owners report high mileage figures, with some engines exceeding 500,000 miles. Key to its longevity is regular maintenance and addressing common issues such as turbocharger failures and fuel system problems.
The engine’s robust design and materials contribute to its overall durability, making it a reliable choice for heavy-duty applications.
Cost Analysis
Initial Purchase Cost
The initial purchase cost of vehicles equipped with these engines can vary significantly. Generally, trucks with the 6.7 Power Stroke diesel engine are more expensive due to the higher cost of diesel technology and its superior performance capabilities.
Maintenance and Repair Costs
Maintenance and repair costs are an important consideration for long-term ownership. Diesel engines typically require more expensive maintenance, but they also tend to have longer intervals between major services.
- 7.3 Godzilla: Lower initial maintenance costs, but potentially higher long-term costs if used heavily.
- 6.7 Power Stroke: Higher initial maintenance costs, but potentially lower long-term costs due to the engine’s durability.
Environmental Impact
Emissions
Diesel engines are known for their higher emissions compared to gasoline engines. However, modern diesel technology has made significant strides in reducing harmful emissions through advanced exhaust treatment systems.
- 7.3 Godzilla: Produces fewer emissions, making it a better choice for those concerned about environmental impact.
- 6.7 Power Stroke: Higher emissions, but advanced systems help mitigate some of the environmental impact.
Fuel Consumption
While the 6.7 Power Stroke is more fuel-efficient on the highway, its overall fuel consumption can be higher due to its greater power output and the types of loads it typically handles. The 7.3 Godzilla, being a gasoline engine, generally consumes more fuel but offers a balance of efficiency and performance for lighter duties.
Use Case Scenarios
Best for Heavy Towing
The 6.7 Power Stroke is the clear choice for those who need maximum towing capacity. Its superior torque and towing capabilities make it ideal for hauling large trailers, boats, and heavy equipment.
Best for Everyday Use
For everyday driving and lighter duties, the 7.3 Godzilla offers a great balance of power, efficiency, and cost-effectiveness. It’s a versatile engine that can handle a variety of tasks without the higher costs associated with diesel maintenance.
Conclusion
Both the 7.3 Godzilla and the 6.7 Power Stroke are outstanding engines, each with their own strengths. The 7.3 Godzilla is a powerful and reliable gasoline engine, ideal for a wide range of applications, from daily driving to light towing. On the other hand, the 6.7 Power Stroke is a diesel powerhouse, built for heavy-duty towing and hauling, with unmatched torque and durability.
When choosing between these two engines, consider your specific needs and priorities. If you require maximum towing and heavy-duty performance, the 6.7 Power Stroke is the way to go. If you need a versatile, efficient, and cost-effective engine for everyday use, the 7.3 Godzilla is an excellent choice.
By understanding the strengths and weaknesses of each engine, you can make an informed decision that best suits your driving habits and requirements.
