The VQ35 engine is a part of Nissan’s venerable VQ engine series, primarily designed as a naturally aspirated V6 engine. Introduced in 2000, the VQ35DE quickly became popular for its blend of good fuel economy, performance, and reliability. Over the years, various versions of the VQ35 have been created, including the DE and HR, each fine-tuned for specific performance criteria.
The VQ35 is a V6 engine, which means it has six cylinders arranged in a V-shape. This configuration is ideal for achieving a balanced mix of power and fuel efficiency. Its compact design also allows for easier placement in a variety of car models, ranging from sporty coupes to bulky SUVs.
While the VQ35 may not be the biggest or most powerful engine in Nissan’s VQ lineup, it's certainly one of the most versatile. It's been used in a wide range of Nissan models and even found its way into other brands under the Renault-Nissan-Mitsubishi Alliance. Its versatility and all-around performance make it a go-to engine within the series.
Depending on the specific model and version, the VQ35 can produce between 230 to 300 horsepower and 240 to 270 lb-ft of torque. This range makes it suitable for a variety of applications, from daily commuting to spirited driving on twisty roads.
The VQ35 has an engine displacement of 3.5 liters. This substantial volume contributes to its ability to produce generous amounts of power and torque across a wide RPM range.
When it comes to fuel efficiency, the VQ35 doesn't disappoint. Averaging between 18 to 26 miles per gallon depending on the vehicle it’s housed in, this engine offers a reasonable compromise between performance and fuel economy.
The VQ35DE 3.5L engine was the first in the line of VQ35 engines and made its debut in 2000. Over its life cycle, it's been featured in a variety of Nissan and Infiniti models, becoming a mainstay for over a decade.
The VQ35DE is equipped with a variable valve timing system and has an engine displacement of 3.5 liters. The engine produces around 230 to 280 horsepower and 240 to 270 lb-ft of torque depending on the specific model. It also features an aluminum block and heads, contributing to its relatively lightweight nature.
The VQ35HR was introduced in 2007 as an updated version of the VQ35DE. The "HR" stands for “High Revolution,” and it lives up to its name with a higher redline and improved power output.
The HR features a reworked dual intake system and an increased compression ratio. The engine block and internals are also more robust, designed to handle the higher RPMs. These enhancements make the VQ35HR more powerful, with horsepower ranging from 260 to over 300.
When it comes to performance, the VQ35HR generally has a slight edge. Its modifications allow it to deliver a crisper throttle response and more power at high RPMs. However, the DE is by no means a slouch and still offers robust performance.
Fuel efficiency between the two engines is relatively similar, but the HR's advanced features may result in slightly better fuel economy in some driving conditions. However, the actual MPG can vary based on the vehicle and driving style.
Both variants are known for their reliability, but the HR comes with a few updates that can extend its lifespan even further. That said, the DE has proven itself time and time again as a dependable engine, making either choice a reliable option.
During its long production run, the Nissan VQ35DE and VQ35HR were used in cars, trucks and SUVs across a wide variety of manufacturers under both the Nissan/Renault umbrella and outside of it.
In its factory setting, the VQ35 engine packs quite a punch, especially when it comes to horsepower. With the DE variant, you can expect anywhere from 230 to 280 horsepower depending on the model and year. The HR takes it up a notch, offering a range from about 260 to over 300 horsepower. These aren't just numbers on a sheet; you'll feel that power every time you step on the gas. Whether you're looking for smooth daily driving or you want that extra oomph for spirited rides, both the DE and HR variants deliver in spades.
In its stock form, the VQ35 engine gives you plenty to smile about. Whether it’s the DE or the HR variant, you're looking at a 0-60 mph time ranging from around 5.5 to 7 seconds, depending on the car it's in. These engines are not just about moving from point A to B; they're about getting there quickly and with style.
As for top speeds, you're generally looking at a range of 130 to 155 mph. Again, these figures can vary based on the car model and specific engine variant.
For those wanting to go beyond stock performance, the VQ35 offers an extensive aftermarket. From cold air intakes and exhaust systems to advanced ECU tuning, the options are almost endless. You can easily bump the horsepower by 20 to 50, depending on how deep your pockets are.
While the VQ35 doesn't come boosted from the factory, there are multiple aftermarket turbo and supercharger kits available. Adding a turbo or supercharger can significantly boost performance but remember, going down this route will need a good deal of expertise and potentially increase engine wear.
If you’re more into optimizing for efficiency than pushing the speedometer, you can do that too. Simple things like keeping the air filter clean and running higher-grade fuel can make a noticeable difference.
Additionally, lighter wheels and low-resistance tires can improve fuel economy. ECU remapping specifically for better mileage can also be an option, but be cautious; modifying engine settings should only be done by professionals.
While the VQ35 engine is generally reliable, there are some mechanical issues that owners should be aware of, ranked from most to least common:
Excessive oil consumption is the most commonly reported issue, especially in older or high-mileage engines. Causes often include worn piston rings or faulty PCV valves. The fix typically involves replacing these parts, which can be somewhat costly but is crucial to prevent future complications related to high oil consumption issues in these Nissan engines.
This issue is less frequent but still significant. Owners report noise coming from the timing chain, particularly during cold starts. This could be due to a stretched chain or worn tensioners and guides. Replacement of these parts is advised to avoid severe engine damage.
While not overly common, problems with the ignition coils can degrade the VQ35's performance and even cause engine misfires. Symptoms may include a rough idle or loss of power, especially under load. Replacing the coils is the go-to solution and should be done promptly to prevent further engine issues.
This is the least common among the listed issues but can still occur. Valve cover leaks can lead to oil leaks and potentially a smoky exhaust if oil drips onto the hot exhaust manifold. Addressing this issue involves replacing the valve cover gaskets to ensure a proper seal.
For a VQ35, regular oil changes are crucial. Depending on your driving habits, an oil change is generally recommended every 3,000 to 5,000 miles.
Beyond oil, regularly check your coolant levels, air filter, and belts. Consistent attention to these components can help you avoid unwanted surprises down the road.
Ownership of a VQ35 engine is generally affordable in terms of repairs. Due to its popularity, parts are readily available and many mechanics are familiar with the engine, which keeps labor costs reasonable.
One of the benefits of the VQ35’s widespread use is the availability of parts. Whether you're shopping for OEM or aftermarket parts, you'll find plenty of options. Prices can vary but are usually moderate, making it easier to maintain or upgrade your engine.
The Nissan VQ35 is a jack-of-all-trades, excelling in performance, reliability, and fuel efficiency. Whether you're after a nimble sports car or a reliable family SUV, this engine won't let you down. Its well-rounded capabilities and robust aftermarket support make it a top pick, whether you're a casual driver or an automotive tuner.
