It begins with the Renault 25 introduced in 1983
Which was then used by AMC/Renault for the Eagle Premier
Which then begat the Chrysler LH Platform
The Daimler-Chrysler merger then allowed the LH to be converted to the RWD Chrysler LX platform using the W201's 5-link rear suspension.
This is then cut down to a shorter wheelbase called the LC which is used as the 2008 Dodge Challenger
Then the platform is adapted for the 2016 MY to fit the ZF 8-Speed Auto which brings us to the LA Platform
