350Z vs. 370Z: Evolution of Nissan Sports Cars and Clutch System Differences

Since the Nissan 350Z was introduced in 2002, it has won the hearts of enthusiasts around the world with its unique design and powerful performance. The 370Z, which was introduced in 2009, has been further refined from its predecessor, not only in terms of power and handling, but also in terms of optimized detail design. In this article, we will take an in-depth look at the clutch systems of these two iconic sports cars, especially the differences between their clutch release bearings (350Z) and throw bearings (370Z).

 I. Introduction

The Nissan 350Z and 370Z, a classic sports car series, have been a favorite among enthusiasts since their introduction. Both models have their own characteristics in terms of exterior design, power performance and interior layout, which bring different driving experiences to drivers. As a key component in the manual transmission, the Clutch Release Bearing (also known as Throwout Bearing in some sources) plays a crucial role in the handling performance of the two models. In this article, we will compare the 350Z and 370Z models and analyze the differences between the clutch release bearings of the two models in depth.

Second, 350z vs 370z model introduction

Nissan 350Z  

- Engine: Powered by the famous VQ35DE 3.5-liter V6 engine with a maximum power of 280 hp (206 kW) and maximum torque of 363 Nm.

- Transmission: 6-speed manual and 5-speed automatic transmission options are available.

- Features: Focusing on direct driver feedback, the manual gearbox is particularly favored by performance enthusiasts. Its clutch system design favors a more direct driving experience.

Nissan 370Z  

- Engine: Equipped with an upgraded VQ37VHR 3.7-liter V6 engine, maximum power has been increased to 332 hp (244 kW) and maximum torque to 366 Nm.

- Transmission: Upgraded to a 6-speed manual transmission and a 7-speed automatic transmission (with manual mode), the latter offering faster shifts and denser gear ratios to help improve acceleration and fuel efficiency.

- What: A more modern design and refined interior, while the clutch system has been optimized to provide a more relaxed driving experience, especially in city driving.

 III. 350z VS 370z Clutch System Comparison

 1. Structural Design

350Z Clutch Release Bearing  

- Design: The clutch release bearing of 350Z adopts the traditional ball bearing design, which has good wear resistance and stability. Its main function is to transfer force through the release fork when the driver depresses the clutch pedal, causing the pressure plate to separate, thus disconnecting the engine from the transmission.

- What: The stock clutch system, especially the clutch release bearing, may need to be replaced after high mileage because its design favors performance over long-term durability.

370Z Throwout Bearing  

- DESIGN: The 370Z's clutch release bearing (throwout bearing) has been structurally optimized with a softer design to reduce the need for clutch pedal effort. This is made possible by its adjusted clutch mechanism, which allows for smoother shifting.

- Features: The 370Z's clutch system has been designed with a greater emphasis on reducing noise and vibration, improving comfort in everyday driving. In addition, the materials and manufacturing process of the throw bearings may have been more optimized to meet the challenges posed by greater power output and a lighter body.

 2. Material

- 350Z: The clutch release bearing is made of high-quality alloy material, ensuring good wear resistance and stability.

- 370Z: Although the same high-quality alloy material is used, the throwout bearing of the 370Z may have been adjusted in the material formula to adapt to higher performance requirements, such as higher heat resistance and fatigue resistance.

 3. Performance

- 350Z: The design of the clutch release bearing favors a more direct driving experience for owners seeking pure driving pleasure. However, this design may wear out after high mileage, resulting in poor shifting or rattling.

- 370Z: The throw-bearing design focuses more on comfort and convenience in daily driving, reducing the driver's effort to maneuver and lowering noise and vibration. This makes the 370Z even better in city driving, as well as suitable for a wider range of driving styles.

350Z  

- Strengths: Direct driving feedback for high-performance driving enthusiasts.

- Weaknesses: may require more frequent maintenance after high mileage, stiffer shift feel.

370Z  

- Strengths: Smoother shifting experience, reduced driver effort, more comfortable for everyday driving.

- Weaknesses: increased complexity of the clutch system, may require more specialized maintenance and technical support.

 4. Compatibility and Maintenance

- 350Z: Due to its more traditional clutch system design, replacing the clutch release bearing is relatively simple, but it should be noted that more frequent maintenance may be required as the vehicle ages.

- 370Z: The 370Z has a more complex clutch system design and may require more specialized techniques and tools for replacement. However, due to its optimized design, its throwout bearing may theoretically have a longer service life or require less maintenance.

Summary:

The differences in clutch systems between the Nissan 350Z and 370Z reflect Nissan's continued responsiveness to driver needs and technological innovations. the 350Z's clutch release bearing emphasizes raw performance and driving engagement for owners seeking pure driving pleasure, while the 370Z's throwout bearing enhances daily driving comfort and convenience while maintaining performance for owners seeking to combine performance with daily driving comfort.
