When it comes to large SUVs, there are two primary construction styles: body-on-frame and unibody. While both have their advantages and disadvantages, they cater to different needs and preferences.
Body-on-frame SUVs, such as the Ford Expedition, Cadillac Escalade, and Jeep Grand Wagoneer, have a traditional truck-based architecture. The body and frame are separate pieces that are eventually joined together during assembly. This construction allows for superior towing capacity and off-road capabilities, making them ideal for those who prioritize ruggedness and utility. However, these SUVs often have larger engines and lower fuel efficiency, and the truck-inspired underpinnings may result in a less comfortable ride on the highway.
On the other hand, unibody SUVs are designed more like sedans, with the body, frame, and chassis integrated into one cohesive unit. This construction style, seen in vehicles like the Kia Telluride and Toyota Grand Highlander, offers better ride comfort, improved fuel efficiency, and higher safety ratings. Unibody SUVs also tend to have more spacious interiors and better handling, making them a popular choice for families who prioritize comfort and versatility. The main drawback of unibody SUVs is their lower towing capacity compared to body-on-frame models.
As the automotive industry has evolved, there has been a shift towards unibody crossovers due to their fuel efficiency and cargo space. Buyers who need the practicality of an SUV but also want better fuel economy are drawn to these sedan-inspired crossovers. However, body-on-frame SUVs still reign supreme in areas like towing and off-roading.
In conclusion, the choice between body-on-frame and unibody SUVs ultimately depends on individual priorities and preferences. Whether it’s the ruggedness and towing capacity of a body-on-frame SUV or the comfort and efficiency of a unibody crossover, there are options available to suit every need.
