2009 Infiniti G37 Gas Mileage

If you're considering purchasing a 2009 Infiniti G37, or already own one and want to understand its fuel efficiency, understanding the 2009 Infiniti G37 gas mileage is crucial. This article provides a comprehensive overview of the fuel economy you can expect from this popular luxury sports sedan, covering different models, driving conditions, and factors that might impact your MPG.

Understanding the 2009 Infiniti G37 Models and Their Fuel Economy

The 2009 Infiniti G37 came in several different configurations, each with its own slightly varying fuel economy ratings. The key differences lie in the drivetrain (rear-wheel drive vs. all-wheel drive) and the body style (sedan, coupe, and convertible). Let's break down the estimated MPG for each:

2009 Infiniti G37 Sedan (Rear-Wheel Drive)

The rear-wheel-drive sedan, arguably the most common configuration, boasts the best fuel economy of the lineup. According to EPA estimates, the 2009 Infiniti G37 gas mileage for the RWD sedan is approximately:

City: 18 MPG
Highway: 26 MPG
Combined: 21 MPG

It's important to note that these are just estimates. Real-world driving conditions can significantly impact these figures.

2009 Infiniti G37 Sedan (All-Wheel Drive)

Adding all-wheel drive improves traction and handling, especially in inclement weather, but it also impacts fuel efficiency. The 2009 Infiniti G37 gas mileage for the AWD sedan is typically:

City: 17 MPG
Highway: 24 MPG
Combined: 19 MPG

The difference might seem small, but over time, the decreased fuel economy can add up.

2009 Infiniti G37 Coupe (Rear-Wheel Drive)

The G37 Coupe, with its sportier profile, offers similar fuel economy to the RWD sedan. Expect approximately:

City: 18 MPG
Highway: 26 MPG
Combined: 21 MPG

Again, these are estimates. Aggressive driving will reduce fuel economy.

2009 Infiniti G37 Coupe (All-Wheel Drive)

The AWD coupe offers the following:

City: 17 MPG
Highway: 25 MPG
Combined: 20 MPG

Slightly improved on the highway compared to the sedan, but roughly the same overall.

2009 Infiniti G37 Convertible (Rear-Wheel Drive)

The G37 Convertible, with its added weight and complexity due to the retractable hardtop, generally sees the lowest fuel economy of the bunch. Expect around:

City: 17 MPG
Highway: 25 MPG
Combined: 20 MPG

The convertible's fuel economy is primarily affected by the added weight of the top mechanism and the body reinforcements.

Factors Affecting Your 2009 Infiniti G37 Gas Mileage

Several factors can significantly influence the 2009 Infiniti G37 gas mileage you experience. Understanding these factors can help you improve your fuel economy:

Driving Habits: Aggressive acceleration, hard braking, and high speeds consume more fuel. Smooth, consistent driving can significantly improve your MPG. Avoid "jackrabbit" starts and unnecessary speeding.
Tire Pressure: Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check and maintain the correct tire pressure as specified in your owner's manual or on the driver's side doorjamb.
Vehicle Maintenance: Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, ensures your engine runs efficiently. A poorly maintained engine will consume more fuel.
Vehicle Weight: Carrying unnecessary weight in your vehicle reduces fuel economy. Remove any items you don't need.
Road Conditions: Stop-and-go traffic, hills, and rough roads reduce fuel economy. Try to avoid these conditions when possible.
Weather Conditions: Extreme temperatures can affect fuel economy. Cold weather reduces tire pressure and increases engine friction, while hot weather can impact air conditioning efficiency.
Fuel Quality: Using the recommended octane fuel (premium is recommended for optimal performance) can improve fuel economy and engine performance.

Tips to Improve Your 2009 Infiniti G37 Gas Mileage

While the G37 is known for its performance, you can still take steps to improve its fuel efficiency. Here are some practical tips to help you maximize your 2009 Infiniti G37 gas mileage:

Drive Smoothly: Avoid aggressive acceleration and braking. Anticipate traffic flow and maintain a consistent speed.
Maintain Proper Tire Pressure: Check your tire pressure regularly and inflate them to the recommended level.
Keep Your Engine Tuned: Follow the recommended maintenance schedule for oil changes, air filter replacements, and spark plug replacements.
Avoid Idling: Excessive idling wastes fuel. Turn off your engine if you're going to be stopped for more than a minute.
Use Cruise Control: On the highway, use cruise control to maintain a consistent speed and improve fuel economy.
Reduce Weight: Remove unnecessary items from your vehicle to reduce weight and improve fuel economy.
Plan Your Trips: Combine errands into a single trip to reduce the number of cold starts, which consume more fuel.
Use Fuel-Efficient Driving Techniques: Learn and practice fuel-efficient driving techniques, such as coasting and avoiding unnecessary acceleration.
Consider a Fuel Additive: Some fuel additives claim to improve fuel economy. Research and choose a reputable product if you decide to use one.

Real-World Gas Mileage vs. EPA Estimates

It's crucial to understand that the EPA estimates are conducted under controlled laboratory conditions. Your actual 2009 Infiniti G37 gas mileage will likely vary depending on your driving habits, road conditions, and other factors. Many drivers report getting mileage that is slightly lower than the EPA estimates, especially in city driving.

Online forums and fuel tracking apps can provide valuable insights into real-world MPG experienced by other G37 owners. Comparing your fuel economy to others can help you identify potential issues or areas for improvement in your driving habits or vehicle maintenance.

Is the 2009 Infiniti G37 Fuel Efficient?

The 2009 Infiniti G37 is a luxury sports sedan, and its fuel economy reflects that. It's not the most fuel-efficient vehicle on the road, but it offers a balance of performance and reasonable gas mileage. Compared to other vehicles in its class, the G37's fuel economy is generally average.

If fuel economy is your primary concern, there are more fuel-efficient vehicles available. However, if you're looking for a stylish, sporty sedan with a powerful engine and engaging driving experience, the G37 offers a compelling package, and its fuel economy is within an acceptable range for its class.

Conclusion

Understanding the 2009 Infiniti G37 gas mileage and the factors that affect it is essential for anyone considering purchasing or owning this vehicle. By being mindful of your driving habits, maintaining your vehicle properly, and following the tips outlined in this article, you can maximize your fuel economy and enjoy the performance and luxury that the G37 has to offer. Remember that the actual fuel economy may vary from EPA estimates, and it's always a good idea to track your own fuel consumption to get a realistic understanding of your vehicle's MPG. The G37 isn't a Prius, but with careful driving, it can be reasonably economical for a performance-oriented luxury car. Don't expect miracles, but do expect a fun and engaging driving experience that's worth the trade-off in fuel economy for many enthusiasts.
