Gizmodo's NASA Put Wheels on Its Mars 2020 Rover and Holy Crap This Is Actually Happening says:

The tube-like legs that support the wheels are constructed from titanium, and they’re similar to high-end bicycle frames in how they’re manufactured, according to NASA. The vehicle’s suspension system is known as a “rocker-bogie” system, having multiple pivot points and struts. When on uneven terrain, this configuration will enable the vehicle to maintain similar weights on each wheel to minimize tilt and keep the rover stable.

During the mission, NASA won’t allow the rover to venture on terrain with more than a 30-degree tilt. That said, the Mars 2020 rover is designed to handle a tilt of 45 degrees in any direction without tipping over, which is quite amazing—that’s half of a 90-degree angle!

Question: How does the Mars 2020 rover's suspension and center of gravity compare to Curiosity's? Are there substantial differences in the way it works or the heights of the CoG or are they fairly similar?
