The Nissan G37 sedan occupies a rare space in automotive history. It delivers analog rear-wheel-drive dynamics, a naturally aspirated V6 engine, and a mechanical layout that modern luxury brands have largely abandoned for turbocharged four-cylinder units and digital interfaces. Long after production wrapped up, enthusiast demand remains high because few cars offer this mix of raw mechanical engagement and everyday practicality at its current price point.
Underneath the hood sits the legendary VQ37VHR engine, a 3.7-liter powerhouse producing 328 horsepower. It revs freely past 7,000 RPM, accompanied by an aggressive exhaust note that defies modern sound regulations and turbo-filtered civility. While contemporary luxury sedans rely on complex hybrid setups and computer-generated cabin audio, the G37 depends entirely on mechanical displacement and hydraulic steering feedback. If you're hunting for a budget-friendly performance vehicle that punches well above its weight class, understanding what makes this platform tick is essential.
Performance Architecture and Powertrain Dynamics
The core of the car's enduring appeal is its chassis and engine combination. Built on Nissan's FM (Front Midship) platform, the engine sits entirely behind the front axle centerline. This layout achieves a near-optimal front-to-rear weight distribution, which translates into neutral handling through tight corners and predictable stability at highway speeds.
The VQ37VHR features Variable Valve Event and Lift (VVEL), combining hydraulic-controlled variable valve timing with electronic lift control on the intake valves. This technology eliminates the traditional throttle butterfly valve's restriction at partial loads, boosting throttle response and upper-rpm breathing. Paired with either a 7-speed automatic transmission featuring rev-matching downshifts or a rare 6-speed manual gearbox, the powertrain delivers linear acceleration without turbo lag.
Rear-Wheel Drive vs. ATTESA E-TS All-Wheel Drive
Buyers face a choice between rear-wheel drive and the G37x all-wheel-drive variant.
- Rear-Wheel Drive (RWD): Models like the Sport (S) trim feature stiffer suspension tuning, larger brakes, a limited-slip differential, and staggered wheels. It's the purist choice for dry pavement dynamics and sliding predictability.
- All-Wheel Drive (AWD): The G37x uses an intelligent torque-split system that routes up to 50 percent of power to the front wheels when slip is detected. It's heavier and lacks the sport-tuned suspension geometry out of the box, but it handles snow and rain with confidence.
Common Mechanical Issues and Real-World Reliability
No vehicle from this era is bulletproof, and knowing the weak points saves you from buying a costly headache. While the mechanical foundation is durable, certain known issues require attention during a pre-purchase inspection.
- Oil Galley Gaskets: Early production models built between 2008 and early 2012 feature paper-thin internal oil galley gaskets that can degrade, causing a drop in oil pressure. Nissan updated this material for the 2013 model year. When inspecting an older car, check for diagnostic trouble codes P0011 or P0021.
- Oil Consumption: The VQ37VHR naturally consumes oil—often around one quart every 1,500 miles. This is a normal design characteristic rather than a sign of internal failure, provided you check the dipstick regularly. Running the engine completely dry on oil, however, will destroy the timing chain guides.
- Catalytic Converters: High exhaust gas temperatures mean the factory metallic honeycomb structure inside the cats can degrade past 150,000 miles. A sulfur smell or a P0420/P0430 code indicates failing units.
- Water Pump Wear: Internal water pumps driven by the timing chain typically reach the end of their service life between 100,000 and 120,000 miles. Replacing them proactively alongside the auxiliary belt prevents coolant leaks.
Interior Ergonomics and Technology Realities
Step inside, and you'll immediately recognize that the cabin belongs to a different era. Physical buttons dominate the center console, flanked by an analog clock that anchors the dashboard layout. This design choice is a major plus for drivers exhausted by touch-screen climate controls.
Materials hold up well over time, though steering wheel leather and seat bolsters show wear on neglected examples. The infotainment system, however, feels dated. Early models feature basic orange-display screens, while later iterations received upgraded high-resolution displays. Many owners upgrade the head unit with aftermarket kits to add modern smartphone integration. Cabin space is competitive for a compact luxury sedan, though rear legroom is tighter than front-wheel-drive competitors due to the longitudinal engine layout.
Marketplace Dynamics and Buying Strategy
Market values for clean examples typically hover between $6,000 and $12,000 depending on mileage, condition, and maintenance records. Finding an un-modified specimen with a complete service history is challenging because these cars are popular targets for cosmetic and performance alterations.
When evaluating options, prioritize 2013 models if your budget allows. They benefit from factory fixes to the oil galley gasket and minor interior refinements. If you find a well-maintained 2010 or 2011 model, verify whether the previous owner addressed routine maintenance items like suspension bushings, spark plugs, and brake fluid flushes.

Frequently Asked Questions
Is the Nissan G37 sedan expensive to maintain?
Routine maintenance is straightforward and affordable compared to German rivals like the BMW 3 Series or Audi A4. Parts are widely available through Nissan and aftermarket suppliers, though premium tires and high-octane fuel add to running costs.
What is the difference between G37 and Infiniti G37?
They are identical. Infiniti is Nissan's luxury division. In North America and several global markets, these vehicles were officially marketed under the Infiniti badge, though their mechanical DNA, parts catalog, and assembly lines trace directly back to Nissan.
Can the automatic transmission handle track use?
The 7-speed automatic transmission handles daily driving and spirited canyon runs without issue, but extended track sessions generate high fluid temperatures. Adding an aftermarket transmission cooler is recommended if you plan on competitive driving.
Does the G37 require premium fuel?
Yes. The high compression ratio of the VQ37VHR engine demands 91 octane or higher fuel to prevent engine knock and maintain optimal power output. Running lower octane fuel triggers knock sensors to retard ignition timing, reducing performance and efficiency.
