The 2009 Nissan Maxima SV sedan with 4 doors represents a distinct era for Nissan’s flagship nameplate, transitioning the vehicle firmly into its seventh generation with a bold design, a driver-focused interior, and a standard 3.5-liter V6 engine paired with a continuously variable transmission. For prospective buyers, automotive enthusiasts, or researchers examining mid-size to full-size Japanese sport sedans, understanding its mechanical layout, trim differentiation, historical reception, and long-term ownership considerations is essential for making an informed evaluation.
Introduction and Subject Identity
When Nissan introduced the redesigned Maxima for the 2009 model year, the company marketed the vehicle as a "4-Door Sports Car" (4DSC), a moniker first popularized by the third-generation Maxima in the late 1980s and early 1990s. The seventh-generation platform (designated A35) departed from the more conservative styling of its predecessor, adopting aggressive, muscular exterior lines, a lower stance, and a cockpit-inspired interior.
Within the 2009 lineup, the model hierarchy was primarily divided into two main trim levels: the base S and the more luxurious, performance-oriented SV. Choosing the 2009 Nissan Maxima SV sedan with 4 doors meant acquiring upgraded amenities such as leather-appointed seating, fog lights, outside mirrors with integrated turn signals, a Bose premium audio system, and access to advanced technology packages that were unavailable on the base S variant.
Evaluating this specific vehicle requires looking beyond its marketing title to analyze how its powertrain, chassis tuning, feature sets, and market positioning hold up. This guide breaks down the technical specifications, driving dynamics, equipment tiers, common ownership considerations, and comparative context of the 2009 Nissan Maxima SV.
Exterior Design and Aerodynamics
The exterior design of the 2009 Maxima SV marked a dramatic stylistic shift from the sixth-generation model. Nissan's design team sought to give the sedan a coupe-like profile while maintaining the practical accessibility of a traditional four-door sedan.
Styling Cues and Proportions
The front fascia features a distinct, aggressive grille flanked by swept-back headlights that incorporate an amber side marker extending into the front fenders. The hood incorporates pronounced character lines that flow into the windshield pillars, creating an athletic visual posture.
On the SV trim, standard exterior enhancements included front fog lights integrated into the lower bumper fascia, chrome door handle accents, and dual exhaust finishers. The side profile is defined by a high beltline, a sweeping roof arc reminiscent of a fastback, and wheel arches designed to accommodate standard 18-inch aluminum-alloy wheels. The rear features wrap-around LED-accented taillights and a subtle decklid spoiler lip.
Aerodynamic Efficiency
Beyond aesthetics, the A35 body shell was engineered to manage airflow effectively at highway speeds. Active and passive aerodynamic measures—including an underfloor engine cover, front air deflectors, and carefully sculpted A-pillars—helped reduce wind noise and maintain high-speed stability. The 4-door architecture maintained a rigid unibody structure utilizing high-tensile strength steel in critical load-bearing areas, improving torsional rigidity compared to the previous generation.
Powertrain and Mechanical Specifications
At the heart of the 2009 Nissan Maxima SV is a heavily revised version of the company’s award-winning VQ35DE 3.5-liter V6 engine. This powerplant serves as the primary mechanical differentiator for the vehicle's dynamic identity.
Engine Architecture and Output
The 3.5-liter V6 features an aluminum block and cylinder heads, dual overhead camshafts (DOHC), and continuous variable valve timing control (CVTCS). In the 2009 Maxima, this engine is tuned to produce 290 horsepower at 6,400 rpm and 261 lb-ft of torque at 4,400 rpm. Fuel delivery is handled by a sequential multi-point electronic fuel injection system requiring premium unleaded gasoline for optimal performance.
Transmission and Drivetrain
Power is transmitted to the front wheels via an Xtronic CVT (Continuously Variable Transmission) equipped with a manual shift mode. Unlike traditional stepped automatic transmissions, the Xtronic CVT utilizes a steel belt and variable-diameter pulleys to provide an infinite ratio range, aiming to optimize power delivery and fuel efficiency. The SV trim includes steering-wheel-mounted paddle shifters, allowing the driver to simulate a 6-speed stepped manual transmission for a more engaged driving experience.

Interior Comfort, Cabin Layout, and Technology
The interior of the 2009 Nissan Maxima SV sedan was designed around a "cockpit" concept, heavily separating the driver's environment from the passenger space through a wrap-around center console.
Seating and Ergonomics
The SV trim replaced the standard cloth upholstery of the base S model with leather-appointed seating surfaces. The front bucket seats feature manual or power adjustments (including an available power driver’s seat with manual lumbar support and thigh extension on select packages). The rear bench seat accommodates three passengers with a fold-down center armrest and integrated cup holders.
Infotainment and Convenience Features
Standard equipment on the SV included a 9-speaker Bose audio system with a 6-disc in-dash CD changer, MP3/WMA playback capability, and an auxiliary input jack. Automatic dual-zone climate control, a leather-wrapped steering wheel with integrated audio and cruise controls, and an auto-dimming rearview mirror with a digital compass were also standard.

Driving Dynamics and Handling
The "4-Door Sports Car" branding placed high expectations on how the 2009 Maxima SV handled twisty roads as well as daily commutes.
Suspension and Steering Tuning
The front suspension utilizes independent struts with coil springs and a stabilizer bar, while the rear features a multi-link independent setup. The SV trim often featured a slightly stiffer spring and damper tuning compared to base configurations, reducing body roll during cornering. The vehicle-speed-sensitive power rack-and-pinion steering provides heavier weighting at highway speeds for enhanced directional stability and lighter effort during low-speed parking maneuvers.
On-Road Performance
Acceleration from 0 to 60 mph takes approximately 5.8 to 6.2 seconds, making it one of the quicker naturally aspirated V6 front-wheel-drive sedans of its model year. While the CVT eliminates traditional shift shock, the simulated manual paddle shifters allow drivers to hold RPM bands during spirited driving. Reviewers noted that while torque steer could be felt under full throttle from a dead stop due to the front-wheel-drive layout and high horsepower output, mid-range passing power was robust.
