The Reason Behind Hatchbacks Having Rear Window Wipers While Sedans Don't
Hatchbacks and sedans often come with different features, but one notable distinction is the presence of a rear window wiper on hatchbacks and its absence on sedans. This article will explore the reasons behind this difference, focusing on design, aerodynamics, target audience, and other practical considerations.
Design and Aerodynamics
The primary reason for the difference in rear window wiper presence between hatchbacks and sedans is the design and aerodynamic considerations of these vehicles.
Design and Shape
Hatchbacks often feature a more vertical rear window, which means there is a larger surface area that can accumulate dirt and water. The larger rear cargo area also makes it more prone to debris and rain accumulation. Due to these factors, a rear wiper is employed to keep the rear window clean and maintain visibility for the driver. In contrast, sedans typically have a more sloped rear design, which facilitates the natural sliding of rain and debris off the window, reducing the need for a wiper.
Aerodynamics and Visibility
Aerodynamics
The sloped rear design of sedans is optimized for better aerodynamics, reducing wind noise and improving overall vehicle efficiency. The angle of the rear window on sedans is such that rain and debris tend to slide off without obstructing the driver's view. This design feature minimizes the need for a rear window wiper, keeping the cost down and maintaining the aesthetic appeal of the sedan.
Target Audience and Usage
Target Audience
Hatchbacks are often marketed towards families or individuals who prioritize practicality and cargo space. These consumers may benefit more from features like a rear window wiper, which can improve rear visibility and cleanliness, especially when transporting larger items. On the other hand, sedans are frequently associated with style, performance, or luxury, where aesthetics and aerodynamics may take precedence over additional functional features.
Usage
Hatchbacks are often used for more versatile purposes, including carrying larger items. This increased need for rear visibility and cleanliness necessitates the presence of a rear window wiper. Sedans, due to their less cluttered rear windows, may only require a de-mister for occasional condensation. However, the cost and practicality of a wiper for a sedan are often deemed unnecessary compared to the benefits it provides for hatchbacks.
Serviceability and Environmental Factors
Serviceability and Costs
Another consideration is the ease of servicing and cost. In hatchbacks and SUVs, the motor and mechanicals for the wiper are often housed inside the hatch door, facilitating easy servicing. This would present installation and maintenance challenges in sedans or coupes, where the rear windows are typically stationary. This factor contributes to the cost differences in manufacturing and potential servicing costs.
Conclusion
Design plays a crucial role in the difference between hatchbacks and sedans regarding the presence of a rear window wiper. While hatchbacks are more likely to have a rear wiper due to their design and usage, sedans are optimized for aerodynamics and aesthetics, making a rear wiper less necessary. Understanding these differences can help consumers make informed decisions based on their specific needs and preferences.
