Nissan Altima Coupes For Sale

The Nissan Altima Coupe, a two-door variant of the ever-popular Altima sedan, offered a sporty and stylish alternative for buyers seeking a more engaging driving experience. Produced from 2008 to 2013, the Altima Coupe presented a unique blend of practicality and performance, albeit one that often goes overlooked in the used car market. This guide delves into the technical aspects of the Altima Coupe, exploring its engine options, chassis design, transmission choices, and common issues to provide a comprehensive understanding of what prospective buyers should consider.

Engine Options: A Balance of Efficiency and Power

The Altima Coupe was primarily available with two engine choices:

2.5-Liter QR25DE Inline-Four

The base engine was the ubiquitous 2.5-liter QR25DE inline-four, a powerplant found in numerous Nissan vehicles. This engine utilizes an aluminum block and cylinder head to minimize weight and enhance thermal efficiency. Key features include:

Dual Overhead Camshafts (DOHC): DOHC configurations allow for greater control over valve timing and lift compared to single overhead camshaft (SOHC) designs. This results in improved airflow and combustion efficiency.

Four Valves Per Cylinder: This setup further enhances airflow, enabling the engine to breathe more freely and produce more power.

Sequential Multi-Port Fuel Injection: This system precisely meters fuel delivery to each cylinder, optimizing combustion and reducing emissions.

Electronic Throttle Control (ETC): Also known as drive-by-wire, ETC eliminates the mechanical linkage between the accelerator pedal and the throttle body, allowing the engine control unit (ECU) to optimize throttle response based on various factors.

The QR25DE in the Altima Coupe generally produced around 175 horsepower and 180 lb-ft of torque, providing adequate performance for everyday driving. However, it's important to note that this engine is known for certain issues, which we'll discuss later. The compression ratio is around 9.6:1, demanding at least regular unleaded gasoline.

3.5-Liter VQ35DE V6

For buyers seeking more exhilarating performance, the Altima Coupe offered the venerable 3.5-liter VQ35DE V6. This engine is a staple in Nissan's lineup and is renowned for its smooth power delivery and robust construction. Its notable characteristics include:

Aluminum Block and Cylinder Heads: Similar to the QR25DE, the VQ35DE employs aluminum construction for weight reduction and improved heat dissipation.

DOHC Configuration: Again, DOHC ensures precise valve control for enhanced performance.

Four Valves Per Cylinder: Maximizing airflow and combustion efficiency.

Continuously Variable Valve Timing Control System (CVTCS): This system continuously adjusts the intake valve timing to optimize performance and efficiency across the engine's rev range.

Sequential Multi-Port Fuel Injection: Ensuring accurate fuel delivery for optimal combustion.

The VQ35DE in the Altima Coupe typically generated around 270 horsepower and 258 lb-ft of torque, transforming the car into a genuinely quick and enjoyable machine. The compression ratio is higher in this V6, around 10.3:1, also requiring at least regular gasoline, though premium fuel may provide slightly improved performance. This engine, while generally reliable, also has its own set of common problems.

Transmissions: Manual and Automatic Choices

Both the 2.5-liter and 3.5-liter Altima Coupes were available with a choice of transmissions:

6-Speed Manual Transmission

The 6-speed manual transmission offered a more engaging driving experience and allowed for greater driver control over gear selection. It featured a relatively short throw and precise shifting action, making it a desirable option for enthusiasts. The transmission’s gear ratios were carefully selected to optimize acceleration and fuel economy. However, like any manual transmission, clutch wear is a factor to consider when evaluating a used Altima Coupe.

Continuously Variable Transmission (CVT)

The CVT, available with the 2.5-liter engine, provided seamless acceleration and enhanced fuel economy. Unlike traditional automatic transmissions with fixed gear ratios, the CVT uses a belt and pulley system to continuously vary the gear ratio, keeping the engine operating in its optimal power band. While CVTs offer advantages in fuel efficiency and smoothness, they can sometimes feel less engaging than traditional automatics or manuals. Early CVTs, like those found in these Altimas, are prone to failure and require diligent maintenance, including regular fluid changes with the correct Nissan-specified CVT fluid.

5-Speed Automatic Transmission

The 3.5-liter V6 was paired with a 5-speed automatic transmission. While not as advanced as the CVT in terms of fuel efficiency, this transmission offered a more conventional driving feel and was generally considered more durable. This transmission is a more standard torque converter automatic and, while less fuel efficient than the CVT, is significantly more robust. Regular fluid changes are still crucial for its longevity.

Chassis and Suspension: A Blend of Comfort and Handling

The Altima Coupe's chassis and suspension were designed to provide a balance of comfort and handling. It featured:

Front MacPherson Strut Suspension: This common front suspension design offers a good compromise between handling and ride comfort. It consists of a strut, coil spring, and lower control arm.

Rear Multi-Link Suspension: The multi-link rear suspension provides independent control over each wheel, enhancing handling and stability.

Front and Rear Stabilizer Bars: These bars reduce body roll during cornering, improving handling responsiveness.

Hydraulic Power Steering: Providing assisted steering, but not as precise as more modern electric power steering systems.

The Altima Coupe's handling was generally considered competent, but not particularly sporty. It was designed more for comfortable cruising than aggressive cornering. The ride quality was also decent, absorbing bumps and road imperfections reasonably well. The chassis is primarily steel, offering a solid platform but also contributing to the vehicle’s overall weight.

Common Issues and Reliability

While the Nissan Altima Coupe can be a good value on the used car market, prospective buyers should be aware of some common issues:

QR25DE Engine Oil Consumption: The 2.5-liter engine is known for consuming oil, particularly in older models. This can be due to worn piston rings or valve stem seals. Regular oil level checks are crucial to prevent engine damage.

CVT Transmission Failures: As mentioned earlier, the CVT in the 2.5-liter models is prone to failure, especially if not properly maintained. Signs of a failing CVT include slipping, hesitation, and unusual noises.

VQ35DE Timing Chain Issues: The VQ35DE, while generally reliable, can experience timing chain issues, particularly in higher-mileage examples. Symptoms include a rattling noise at startup and poor engine performance.

Rust: Depending on the geographic location, rust can be a concern, particularly on the undercarriage and body panels.

Electrical Problems: Some owners have reported electrical issues, such as problems with the windows, door locks, and audio system.

Pre-purchase inspections are highly recommended to identify any potential problems before buying an Altima Coupe. Pay close attention to the engine's oil level, the transmission's performance, and the overall condition of the car. A mechanic can perform a compression test to assess the health of the engine and check for any signs of wear or damage.

Conclusion

The Nissan Altima Coupe offers a unique combination of style, practicality, and performance. While it may not be the sportiest coupe on the market, it provides a comfortable and enjoyable driving experience. However, prospective buyers should be aware of the potential issues, particularly with the QR25DE engine and the CVT transmission. By carefully inspecting the car and addressing any necessary repairs, buyers can find a reliable and affordable Altima Coupe that meets their needs.
