2007-2009 Nissan 350Z Roadster (Z33 facelift ) 3.5i V6 24V (313 Hp) Automatic

The Nissan 350Z Roadster, specifically the facelifted version produced from 2007 to 2009, represented a compelling blend of performance and open-air driving enjoyment. This iteration, designated as the Z33, continued the 350Z lineage initiated in 2003, offering a more refined and mature experience compared to earlier models. The 3.5i V6 24V variant, equipped with a five-speed automatic transmission, occupied a middle ground within the Roadster lineup, providing a balance between accessibility and spirited performance. It was positioned as a more comfortable and user-friendly option compared to the six-speed manual transmission, while still delivering a substantial power output for its class.

Powertrain & Engine Architecture

The heart of the 2007-2009 Nissan 350Z Roadster 3.5i Automatic is the VQ35HR engine. This 3.5-liter, naturally aspirated V6 is a significant evolution of Nissan’s highly regarded VQ engine family. The “HR” designation stands for “High Revolution,” indicating a focus on increased power output at higher engine speeds. The engine utilizes a dual overhead camshaft (DOHC) design with four valves per cylinder, and a variable valve timing system (VVT) on both intake and exhaust camshafts. This VVT system, known as Continuously Variable Valve Timing Control System (CVTCS), optimizes engine performance across a wider range of RPMs. Fuel delivery is managed by a multi-port fuel injection system. The engine produces 313 horsepower at 6800 rpm and 264 lb-ft of torque at 4800 rpm. The five-speed automatic transmission, a Jatco unit, was chosen for its smoothness and ease of use. While not as sporty as the available six-speed manual, it offered a more relaxed driving experience, particularly in city traffic.

Driving Characteristics

The 350Z Roadster 3.5i Automatic delivers a respectable level of performance. While the automatic transmission does introduce some power loss compared to the manual, the VQ35HR engine still provides ample acceleration. The automatic transmission’s gear ratios are tuned for a balance of acceleration and fuel efficiency. In typical driving conditions, the transmission shifts smoothly and predictably. However, it lacks the responsiveness and driver engagement of a manual gearbox or a more modern automatic with paddle shifters. The rear-wheel-drive configuration contributes to a balanced chassis and predictable handling. The Roadster’s relatively short wheelbase and well-tuned suspension provide a sporty feel, although the added weight compared to the coupe is noticeable in cornering.

Equipment & Trim Levels

The 3.5i Automatic trim level typically included standard features such as leather upholstery, automatic climate control, a Bose premium audio system, power-adjustable seats, and alloy wheels. Optional extras included a navigation system, a sunroof, and various cosmetic enhancements. The interior design was driver-focused, with a clear and concise instrument panel. The Roadster’s convertible top was a power-operated soft top, offering a relatively quiet and comfortable open-air experience. The 2007 facelift brought minor interior refinements, including updated trim materials and improved switchgear.

Chassis & Braking

The 350Z Roadster utilizes a MacPherson strut front suspension and a multi-link rear suspension. This setup provides a good balance of ride comfort and handling performance. The chassis is reinforced compared to the original 350Z to compensate for the loss of structural rigidity associated with the convertible body style. Braking duties are handled by ventilated disc brakes at all four corners. The braking system provides ample stopping power, although the Roadster’s slightly higher weight compared to the coupe requires a bit more stopping distance. Anti-lock brakes (ABS) and electronic brake-force distribution (EBD) are standard features.

Market Reception & Comparison

The 2007-2009 Nissan 350Z Roadster 3.5i Automatic was generally well-received by automotive critics. It was praised for its powerful engine, sporty handling, and comfortable interior. However, some reviewers noted that the automatic transmission detracted from the overall driving experience. Compared to the six-speed manual version, the automatic offered slightly lower fuel economy and slower acceleration times. Compared to other roadsters in its class, such as the Mazda MX-5 Miata and the BMW Z4, the 350Z Roadster offered a more powerful engine and a more aggressive styling, but it was also larger and heavier.

Legacy

The VQ35HR engine, in general, has proven to be a remarkably reliable powerplant. With proper maintenance, it can easily exceed 200,000 miles. The Jatco five-speed automatic transmission is also generally reliable, although some units have experienced issues with valve body wear over time. On the used car market, the 350Z Roadster 3.5i Automatic remains a popular choice for enthusiasts seeking an affordable and engaging sports car. Its combination of performance, style, and relative reliability makes it a compelling option for those looking for an open-air driving experience. However, potential buyers should be aware of the potential for rust, particularly in areas with harsh winters, and should carefully inspect the vehicle for any signs of previous damage or neglect.
