Why the 2006 Infiniti G35 Remains a Modern Performance Classic

The mid-2000s marked a golden era for Japanese luxury sports cars, and at the heart of this revolution was the 2006 Infiniti G35. Positioned as a direct challenger to the dominance of the BMW 3 Series, the G35 didn't just compete—it redefined what enthusiasts expected from a daily-drivable performance machine. Built on a chassis shared with the legendary Nissan 350Z, the 2006 model year represents the pinnacle of the V35 generation, offering a refined blend of analog mechanical soul and early digital convenience.

The Heart of the Beast: The VQ35DE Engine Architecture

The soul of any G35 is its power plant. For 2006, Infiniti continued to utilize the multi-award-winning 3.5-liter V6, known internally as the VQ35DE. However, not all G35 engines of this year were created equal, and understanding the nuance between the versions is critical for any prospective owner.

The Standard Output vs. The RevUp Version

In the 2006 lineup, the output depended heavily on the choice of transmission. The automatic-equipped models—both the rear-wheel-drive sedan and the G35x all-wheel-drive—delivered 280 horsepower and 270 lb-ft of torque. This version of the engine focused on a broad torque curve, making it an effortless cruiser in urban environments.

For those who opted for the 6-speed manual transmission (6MT), Infiniti provided a specifically tuned version of the VQ35DE, often referred to by enthusiasts as the "RevUp" engine. This variant pushed the output to 298 horsepower. While it sacrificed a small amount of peak torque (260 lb-ft), it featured a higher redline and revised internal components, including variable valve timing on both the intake and exhaust sides. This made the 6MT model a significantly more visceral experience, rewarding drivers who were willing to wring the engine out to its 7,000 RPM limit.

Performance Engineering Details

The VQ35DE was more than just raw numbers. It featured:

• Microfinished Crankshaft and Cam Lobes: Reducing friction for smoother operation and longevity.
• Molybdenum-Coated Pistons: Designed to handle high heat and rapid movement within the cylinders.
• Electronic Throttle Control: A "drive-by-wire" system that allowed for more precise engine response and integration with the vehicle's stability control systems.

The FM Platform: A Lesson in Balance

One of the most significant technical achievements of the 2006 Infiniti G35 was its utilization of the "Front Midship" (FM) platform. While many cars of its era were front-heavy, the G35's engine was positioned further back toward the firewall, behind the front axle line.

Weight Distribution and Handling

This engineering choice resulted in a front-to-rear weight distribution of roughly 52:48 or 53:47 depending on the body style. By centralizing the mass, Infiniti reduced the polar moment of inertia, allowing the G35 to rotate more naturally through corners. When you dive into a sharp apex in a G35, you don't feel the front end pushing (understeering) as aggressively as you might in a front-wheel-drive-based luxury car. Instead, the steering remains communicative, and the chassis feels neutral.

Suspension and Braking

The 2006 model featured a 4-wheel multi-link independent suspension constructed heavily from lightweight aluminum components. This reduced "unsprung weight," allowing the suspension to react faster to road imperfections and maintain tire contact.

For the 2006 model year, the braking system was equally robust. With 12.6-inch vented discs in the front and 12.1-inch in the rear, paired with Electronic Brake Force Distribution (EBD) and Brake Assist (BA), the G35 provided confident stopping power that matched its straight-line speed.

Sedan vs. Coupe: Two Personalities, One DNA

Infiniti offered the G35 in two distinct body styles, each catering to a different lifestyle while maintaining the same performance core.

The 2006 G35 Sedan: The Practical Performance Choice

The sedan was the sleeper of the family. With a 112.2-inch wheelbase and four doors, it offered genuine seating for five and 14.8 cubic feet of trunk space. It was the perfect choice for the enthusiast who needed to drop kids off at school before heading to a weekend track day.

• The G35x AWD: A specific highlight of the sedan lineup was the "intelligent" all-wheel-drive system (ATTESA E-TS). This system favored rear-wheel drive for performance but could split torque up to 50:50 if sensors detected slip, making it a favorite for buyers in the "snow belt."

The 2006 G35 Coupe: The Style Icon

The G35 Coupe was, and remains, a design masterpiece. It was shorter, wider, and lower than the sedan, with a more aggressive stance emphasized by its flared wheel arches. The 2006 Coupe benefited from standard 17-inch or optional 18-inch and 19-inch wheels.

• 19-inch Forged Wheels: The sport-tuned 6MT models came with stunning 19-inch forged aluminum-alloy wheels made by RAYS, which were significantly lighter and stronger than cast alternatives, improving both aesthetics and handling.

What’s New for 2006? The Mid-Cycle Refinements

The 2006 model year is often cited as the best year to buy for the V35 generation because it benefited from several mid-cycle "refreshes" that addressed early complaints.

Exterior Enhancements

Infiniti updated the lighting for 2006, introducing Bi-Xenon (HID) projector-beam headlights that provided superior night visibility. The rear received a significant upgrade with LED taillights, which not only looked more modern but responded faster to braking inputs. A new color, "Liquid Platinum," replaced older silver hues, giving the car a more premium, metallic luster.

Interior and Technology Upgrades

Inside, the 2006 G35 saw a massive improvement in material quality. The earlier years were criticized for having too much "hard plastic." The 2006 model introduced:

• Refined Trim Options: Genuine Rosewood trim became available, and the aluminum accents were revised for a more authentic feel.
• Bluetooth Connectivity: The 2006 Premium Package added a Bluetooth hands-free phone system, a cutting-edge feature at the time.
• Intelligent Key: This allowed for keyless entry and starting, a convenience that many modern drivers now take for granted but was a luxury hallmark in 2006.

Real-World Driving Dynamics: The Enthusiast's Perspective

Driving a 2006 Infiniti G35 is an exercise in sensory feedback. Unlike modern cars that feel isolated by electric power steering and heavy sound deadening, the G35 connects you to the asphalt.

The Sound of the VQ

One of the G35's most famous attributes is its exhaust note. Infiniti's engineers specifically tuned the muffler to produce a distinct, metallic "growl" that is instantly recognizable. Under hard acceleration, the VQ35DE sings a resonant V6 tune that becomes a high-pitched wail toward the redline. It’s a sound that many modern turbocharged engines simply cannot replicate.

Handling and Steering

The steering is heavy by modern standards, but it’s a "good" heavy. You can feel the texture of the road and the limits of the front tires. In our experience, the G35 remains remarkably stable at high speeds, thanks in part to its zero-lift aerodynamics. The optional "Rear Active Steer" system available in 2006 further enhanced agility by slightly turning the rear wheels in opposition to the front at low speeds and in phase at high speeds, effectively making the car feel shorter on tight corners and more stable on the highway.

Buying a Used 2006 G35: The Reliability Guide

If you are looking at a 2006 G35 today, you are likely looking at a high-mileage vehicle. While these cars are fundamentally robust—often exceeding 200,000 miles with ease—there are specific "hot spots" to check.

1. Oil Consumption (The RevUp Issue)

The 298hp "RevUp" engines found in the 6MT models are notorious for oil consumption. This was often due to piston ring issues in early batches. When inspecting a 6-speed manual car, check the oil level immediately and ask for service records. Some engines were replaced under warranty by Infiniti, which is a significant plus.

2. Suspension Bushings (Compression Rods)

The front suspension design, while great for handling, uses "compression rods" with bushings that are prone to cracking. If you hear a "clunk" or "creak" when going over speed bumps or turning at low speeds, the bushings likely need replacement. Many owners opt for aftermarket polyurethane bushings for a permanent fix.

3. Camshaft and Crankshaft Position Sensors

These sensors are common failure points across the Nissan/Infiniti VQ engine family. A failing sensor can cause the car to stall, enter "limp mode," or fail to start. They are relatively inexpensive and easy to replace, but it’s worth noting if the "Check Engine" light is on.

4. Interior Wear (The "Sticky" Dash and Seats)

While 2006 was an improvement, the leather bolsters on the seats and the soft-touch plastic on the dashboard can show wear. Check the driver's side seat bolster for cracks and ensure the steering wheel buttons haven't peeled.

5. Window Motors and Door Lock Actuators

Infiniti vehicles of this era suffered from weak window motors. If a window moves slowly or requires multiple clicks to close, the motor is on its way out. Similarly, door lock actuators can fail, preventing the remote from locking or unlocking specific doors.

How the 2006 G35 Compares to the Competition

To understand why the G35 was so disruptive, we have to look at its rivals in 2006.

The BMW 330i was perhaps more "refined" in its suspension tuning, but it was also more expensive and had less power. The Lexus IS350 was faster in a straight line, but its lack of a manual transmission and more isolated steering made it less appealing to pure driving enthusiasts. The G35 sat in the "Goldilocks" zone—it offered the most raw, engaging experience for the money.

Modifiability: The G35 Enthusiast Scene

One reason the 2006 G35 remains popular today is its massive aftermarket support. The VQ35DE is a stout engine that can handle moderate boost from turbochargers or superchargers.

• Breather Mods: High-flow intakes and plenum spacers (like the Motordyne spacer) are popular for unlocking trapped horsepower.
• Stance and Suspension: From BC Racing coilovers to air suspension, the G35 is a favorite in the car show scene due to how well it "takes" to a lowered stance.
• Exhaust Systems: Brands like Tomei and Motordyne offer exhaust systems that amplify that signature VQ growl into a symphonic masterpiece.

Is the 2006 Infiniti G35 Worth Buying Today?

The answer depends on what you value in a car. If you want the latest infotainment, active lane-keeping, and 30 MPG, look elsewhere. The G35 is a thirsty car, typically averaging 18-22 MPG on premium fuel.

However, if you want a car that feels "mechanical," looks timeless, and can keep up with modern traffic, the 2006 G35 is an incredible value. It is one of the last great "analog" sports sedans before the industry moved toward electric power steering and overly complex turbocharged engines.
