Here we will try to cover the new features but our review will be very similar to our Britax Advocate CS review, since there are very few changes in this model.

So What is new with Britax Advocate 70 G3 Convertible Car seat?

The first feature highlighted in Britax’s website is the EZ-Buckle System. Its duty is to solve a very simple but common problem with car seats. The new buckle system is designed to prevent you child from sitting on the buckle. The EZ-Buckle System will cause the harness to flip forward when your child gets out of the car seat, so you will not have to search for it the next time.

The next improvement is the HUGS Chest Pads with SafeCell Technology. The new system’s pads are now thicker than previous versions to absorb more energy in case of a collision. One disadvantage here is that these new HUGS pads are tethered to the shell which makes it a little harder to loosen the straps by grabbing the HUGS pads than previous version. With the new design the only way is to use your fingers.

The Versa-Tether of Advocate 70 G3 model comes with built-in energy absorbing feature which will reduce the forces on a child in a crash a little better than old tether system.
These are the important changes in this new generation Advocate convertible car seat. Other than those some we see some color changes which are not important in terms of usage or safety.

Safety Features of The Britax Advocate 70 G3

True Side Impact Protection: The Britax Advocate 70 G3 is equipped with side cushions to soften the impact from a side collision as much as 45%. It also protects the person sitting beside the car seat, preventing them from injury by the car seat itself hitting them during a crash.

Base with SafeCell Technology: EPP foam, covers the entire shell, and steel bars reinforce the seat, making it durable and strong. The Britax Advocate 70 G3 features Britax’s special SafeCell Technology like previous models. In the car seat base there are small cells engineered to compress instantly when in an accident, lowering the car seat’s center of gravity, counteracting the forward rotation of the child seat.

Harness Ultra Guard System: Another excellent safety feature is the built-in lock-offs to assure correct installation. The Harness Ultra Guard System or HUGS keep your child’s head stationary, stopping it from going forward during an accident. The Britax Advocate 70 G3 comes with a new HUGS system which you cannot find on previous models like the Britax Advocate CS or the Britax Boulevard 70. The new pads are now thicker than previous versions to absorb more energy in case of a collision.

Energy-Absorbing Versa-Tether: The patented, energy absorbing versa-tether has staged-release tether webbing, anchoring the top of the seat at two points which minimizes forward movement to provide additional protection. Energy-Absorbing Versa-Tether in Advocate 70 G3 model is also upgraded, it comes with built-in energy absorbing feature which will reduce the forces on a child in a crash a little better than old tether system.

Ease of Installation

The Britax Advocate G3 is a very simple car seat to install. If your car is equipped with LATCH connectors and your child is less than 40 pounds, then using the LATCH system to secure your child in the Britax car seat is the safest way to go. Some LATCH systems can be used for an even higher weight limit. Check your car manual for more information about the LATCH connectors in your vehicle. The LATCH system may be used with the car seat in either the front or rear facing positions. There is also a tether system which is used with the Britax D-ring. Secure it around any fixed metal piece in your car such as a seat leg. If you still have questions, Britax’s installation instruction card complete with diagrams comes with every Advocate car seat.
