Reminds me of the glory days of Pro-Touring Panteras (circa 1980s - even before that term was coined), and of twin-turbo Panteras with radically re-engineered chassis like this:
The pushrod suspension has many advantages for a racecar. A brief history: Rockerarm suspensions became popular in the late 70's with huge packaging advantages driven largely by the latest aero designs. With the advent of ground effects spring-rates then skyrocketed and the "rocker arms" ended up becoming essentially an "un-damped leaf spring". Enter the push and pull rod suspensions. These also allow greater flexibility for optimizing the motion-ratios and curves for better wheel control and with lighter springs, faster spring adjustments/swaps, and the advantages mentioned above.
The pushrod suspension was also used in the post-Pantera Guara (designed by, as I recall reading somewhere, by the Williams F1 team). So seems a natural fit for a new state-of-the-art Pantera chassis.
Although I suspect one of the main factors here is also the racecar-like "cool factor" ... and on that account they nailed it! Indeed one of the coolest Pantera projects I've seen!!
