Leaf springs have been a trademark of Corvette for a pretty long time. The most recent generations of Corvette kicked up the leaf spring presence a notch by employing both front and rear transverse leaf spring configurations.
The usual song and dance presented to the general public justifying retention of this truly archaic set up was the weight reduction benefit (in addition to the other standard issue bullshit like handling benefits and compact design).
The fact that lack of fully independent suspension on Corvette due to these leaf springs is a major obstacle in creating a mid engine drive car, just like Duntov wanted is a given, at least to those outside of +General Motors kool aid drinkers. However, the newest generation of Corvette brought up another aspect of Corvette ongoing shortcomings, making it perpetually inferior to actual track and street high performance alternatives: the weight reduction claim.
In spite of +Tadge Juechter 's truly pathetic attempt at misinformation by implying that the new "light weight" frame would lead to a lighter car, the weight of the newest generation of Corvette increased significantly over the previous generation. Where this disgraceful failure is especially and painfully obvious is the upcoming 2015 Corvette Z06. This porker in certain configurations can weight over FIVE HUNDRED POUNDS MORE than C6Z06!!!
Now, the question should be raised, where is the point where bullshit excuses such as weight savings of leaf springs should be permanently discarded from the Corvette marketing fairy tales? Obviously the weight saving excuse is just as much a valid reason for this propagation of equestrian origins of Corvette as the latest oil filter fable.
Furthermore, another question should be asked: how much of a failure this new Z06 really is and what would it weigh if it came with real track worthy suspension consisting of (fully adjustable) coil overs? Would the Z06 porker weigh over 3800 pounds, making new, steel bodied Camaro Z28 the new GM high performance weight savings leader?
The lack of coil over suspension is nothing new for Corvettes, it did not happen on C5, and it did not happen on C6 cars, including the 120k ZR1. Of course there is an exception in race only Pratt Miller R versions which further undermine the track ability of commercially available Corvettes.
To see a car advertised as a pinnacle of "race bred" technologies, getting by in a best horse buggy tradition, lacking completely suspension tuning abilities (no, the MSRC does not qualify for this honor) is truly inconceivable. What is even more depressing and frustrating is the newest generation of Corvette ability to include any of the modern sports car technologies due to the residual weight handicap that would certainly make any future improvements self defeating.
The future of Corvette looks very bleak when all weight saving technologies lead to a car that literally outweighs competition that does not use such archaic designs, allowing those cars to constantly improve.
Like with the pushrod engine design that led to the massive sudden death problems of LT1 turds, reliance on ancient suspensions is a dead end street as well. What is even more peculiar is the fact that Camaro designers understand this part while the ship of idiots called Corvette engineering team, with +Tadge Juechter appears to be completely oblivious to this aspect of car design. Seems like Juechter may be one of those so called CHUBBY CHASERS?
