1: Improve fuel consumption
Luggage rack increases the weight of the car, wind resistance coefficient increased suddenly, the overall fuel economy is not friendly, off-road vehicles face road conditions itself is more complex, fuel consumption itself will not be too low, luggage racks and luggage racks above the luggage, further increasing the quality of the car, for the refueling inconvenience of the remote areas, it is still very noteworthy, you need to real-time judgment of the fuel tank fuel can support you to complete the crossing.
2: Impact on power handling performance
From the point of view of off-road vehicle design and aerodynamics, the original vegetation car does not consider the installation of luggage racks, luggage racks have a negative impact on the weight, wind resistance, while the luggage racks also raise the center of gravity of the car, these factors also affect the handling performance of the car.
3: Driving noise increase
Luggage rack + luggage, so that the roof of the impact of the wind area greatly increased in driving resistance at the same time, the noise will also be very obvious, off-road vehicle mute performance itself is not very good, high-speed driving overhead "whirring" noise, not every owner can accept.
4: luggage racks lead to safety hazards
Some people may wonder, what is the relationship between luggage rack and safety? Luggage rack belongs to the modification parts, in the fixing involves a strength matching problem, not every luggage rack can provide the perfect strength of retrofitting, even if it is welded, the continuous bumps of the scrubber road will not be merciful to you. The luggage rack is fixed to the body and the luggage is fixed to the luggage rack. Once the luggage rack is not strong enough for safety or the luggage is not fixed securely, there is a high risk of a dangerous accident of the luggage rack as a whole or of the luggage slipping off. If there is no special luggage need to load often, it is not recommended to install luggage rack.
5: Aesthetics
The aesthetics of the luggage rack is also a factor that has to be considered when modifying. For example, a cool shape like a city SUV crossover (Isuzu mu-X, Touareg Y62, Toyota Prado, Toyota Land Cruiser, etc.) to add a four-square luggage rack. Four square hardcore off-road vehicles (Mercedes-Benz G-Class, Jeep Wrangler, Toyota LC7 Series, etc.) plus a city SUV commonly used "sissy" shaped luggage rack, also very ugly. I'm sure the owners don't want to attract passers-by to look at them because they are ugly.
