Unibody Construction: Frame + Body = Modern-day Vehicle
Deciphering unibody construction is only slightly more challenging, since it comes from the phrase unitized body.
In other words, with these vehicles, the body and frame are considered one unit.

Are unibody cars better?
Unibody vehicles have the advantage of being lighter than their body-on-frame counterparts. This translates to better fuel economy ratings. Their lower center of gravity and more rigid frame also make them much less prone to vehicle rollover. Unibody designs also score higher on crash safety test ratings.
What cars are body on frame?
Here, it offers models such as the Toyota 4Runner, Sequoia and Land Cruiser, as well as Lexus GX and LX models. Mercedes G-Class SUVs are body-on-frame, as is the Nissan Armada and its companion Infiniti QX80. As the name suggests, unibody frames, are made with the frame and body combined into one piece.
Can a unibody frame be fixed?
Unibody construction means that the frame and the body of the car are one. That means that if there is damage to the body, usually there will also be damage to the frame. However, unibody frame damage is much easier to repair in modern vehicles than older vehicles.
Are unibody cars safer?
Though a unibody vehicle may have frame rails, those rails are tied to the vertical surfaces of the body to increase strength. In some cases, vehicles are a combination of both construction techniques. However, would unibody construction be safer in the event of a crash?
What does unibody damage on a car mean?
Unibody damage on car is typically caused by a major accident, and leaves the frame of the vehicle weaker than it originally was. While unibody damage can be partially repaired, it is a major liability for anyone who owns the vehicle because another accident could result in catastrophe.
Is a unibody stronger than a frame?
It is easier to repair the body-on-frame vehicle as parts are replaced as needed. A unibody is typically safer because the whole body is designed to absorb the forces of impact, but that means more extensive damage and in some cases the integrity is compromised.
Is a truck better than a car?
The Pros. Easy-to-Drive – One of the biggest benefits of driving normal cars is that they are easier to drive on city roads as compared to pickup trucks. This is mainly because they are more compact and have low ground clearance. Gas Mileage – If gas mileage matters to you, then there can be nothing better than a car.
Do unibody cars have frames?
Until the 1930s virtually every car had a structural frame, separate from its body. Over time, nearly all passenger cars have migrated to unibody construction, meaning their chassis and bodywork have been integrated into one another.
What is the difference between unibody and body on frame?
Rather than using a body placed around a separate frame, the frame and body in unibody vehicles are one single piece. Generally speaking, unibody vehicles don’t quite offer the same off-roading capabilities as body-on-frame models, as they usually aren’t as resistant to twisting forces.
Is frame damage bad?
Damage to one part of the shell essentially affects the entire structure. Though damaged sections of a unibody frame can be replaced, driving a vehicle that’s undergone structural damage should be considered a safety risk. What’s more, the underlying damage can cause additional mechanical problems later on.
What SUVs are still body on frame?
6 American SUVs That Still Feature Body-on-Frame Construction
- Chevy Suburban.
- Chevy Tahoe.
- Ford Expedition.
- GMC Yukon.
- Jeep Wrangler. The Jeep Wrangler seems out-of-place on this list by virtue of its size.
- Cadillac Escalade. The Cadillac Escalade is one of the most recognizable SUVs in the market.
