Engine Options and Horsepower

The 2007 Infiniti G35 sedan came with a couple of engine options, both variations of the VQ35DE 3.5-liter V6 engine. This engine is renowned for its smooth power delivery, reliability, and tunability. Let's break down the horsepower figures for each:

Base Model

The base model of the 2007 Infiniti G35 sedan produces around 275 horsepower. This is more than enough oomph for daily driving and spirited runs. The VQ35DE engine delivers power linearly, making it predictable and fun to drive. Whether you're merging onto the highway or overtaking slower traffic, the base model G35 has plenty of punch.

Sport Model

The sport model of the 2007 Infiniti G35 sedan ups the ante with approximately 306 horsepower. This bump in power comes from minor tweaks to the engine and exhaust system. The sport model also includes sport-tuned suspension, bigger brakes, and other performance enhancements that make it a more engaging driving experience. If you're looking for a G35 with extra zing, the sport model is the way to go.

Factors Affecting Horsepower

Several factors can influence the actual horsepower output of your 2007 Infiniti G35 sedan. These include:

• Engine Condition: A well-maintained engine will produce more power than one that has been neglected. Regular oil changes, new spark plugs, and a clean air filter are essential for keeping your G35 running at its best.
• Fuel Quality: Using high-quality fuel can also impact horsepower. Premium fuel with a higher octane rating can help your engine run more efficiently and produce more power.
• Modifications: Aftermarket modifications such as exhaust systems, air intakes, and ECU tunes can significantly increase horsepower. However, it's essential to choose reputable brands and have these modifications installed by qualified professionals to avoid damaging your engine.
• Environmental Conditions: Air temperature and altitude can also affect horsepower. Colder air is denser and contains more oxygen, which can lead to increased power output. Conversely, hotter air is less dense, which can reduce horsepower. Higher altitudes also have less oxygen, which can impact performance.

Performance and Driving Experience

The 2007 Infiniti G35 sedan isn't just about horsepower; it's about the overall driving experience. The car handles beautifully, with a responsive steering system and well-tuned suspension. Whether you're carving up twisty roads or cruising on the highway, the G35 delivers a comfortable and engaging ride.

Acceleration

The base model of the 2007 Infiniti G35 sedan can accelerate from 0 to 60 mph in around 6.0 seconds. The sport model is slightly quicker, achieving the same feat in about 5.7 seconds. These are respectable figures for a sports sedan of this era.

Handling

The G35's rear-wheel-drive layout and balanced chassis make it a joy to drive. The car feels planted and stable in corners, inspiring confidence even when pushing the limits. The sport model's upgraded suspension further enhances handling, reducing body roll and improving overall control.

Transmission

The 2007 Infiniti G35 sedan was available with either a 5-speed automatic transmission or a 6-speed manual transmission. The manual transmission is the choice for enthusiasts who want maximum control and engagement. The automatic transmission is smooth and responsive, making it a good option for daily driving.

Comparing with Competitors

In 2007, the Infiniti G35 sedan competed with other luxury sports sedans such as the BMW 3 Series, Audi A4, and Acura TL. Here's how the G35's horsepower stacks up against its rivals:

• BMW 3 Series: The BMW 3 Series offered a range of engines, with horsepower ranging from around 215 to 300, depending on the model.
• Audi A4: The Audi A4's horsepower ranged from approximately 200 to 255, depending on the engine option.
• Acura TL: The Acura TL produced around 258 to 286 horsepower, depending on the model year and trim.

As you can see, the 2007 Infiniti G35 sedan offered competitive horsepower figures compared to its rivals. The G35 also stood out for its attractive styling, luxurious interior, and sporty driving dynamics.

Reliability and Maintenance

The VQ35DE engine in the 2007 Infiniti G35 sedan is generally reliable, but like any car, it requires regular maintenance to keep it running smoothly. Here are some common maintenance tasks:

• Oil Changes: Regular oil changes are crucial for keeping the engine lubricated and preventing wear. Infiniti recommends changing the oil every 3,750 miles or six months, whichever comes first.
• Spark Plugs: Replacing the spark plugs at the recommended interval (usually around 100,000 miles) is essential for maintaining optimal engine performance.
• Air Filter: A clean air filter ensures that the engine receives a sufficient supply of air. Replace the air filter every 12,000 to 15,000 miles.
• Coolant Flush: Flushing the coolant system every two to three years helps prevent corrosion and overheating.
• Transmission Fluid: Changing the transmission fluid at the recommended interval helps keep the transmission shifting smoothly.

In terms of reliability, the VQ35DE engine is known for its durability. However, some common issues to watch out for include oil leaks, timing chain problems, and valve cover gasket leaks. Addressing these issues promptly can prevent more significant problems down the road.

Aftermarket Upgrades

If you're looking to extract even more horsepower from your 2007 Infiniti G35 sedan, there are numerous aftermarket upgrades available. Here are a few popular options:

• Exhaust System: A cat-back exhaust system can improve exhaust flow, resulting in increased horsepower and a sportier sound.
• Cold Air Intake: A cold air intake can increase the amount of air flowing into the engine, which can lead to a slight horsepower gain.
• ECU Tune: An ECU tune can optimize the engine's air-fuel ratio and ignition timing, resulting in increased horsepower and improved throttle response.
• Forced Induction: Installing a supercharger or turbocharger can significantly increase horsepower. However, forced induction requires careful planning and professional installation to avoid damaging the engine.

Before making any modifications, it's essential to research reputable brands and consult with qualified professionals. Some modifications may void your warranty, so keep that in mind.

Conclusion
