“Even the old Beetles had 4-wheel independent suspension.”
Both the Camaro and the Mustang have IRS and their track versions are amazing, particularly the Camaro with 650 hp.
This implies that the Challenger doesn't. It indeed does have 4-wheel independent suspension, and had it ever since it's 2008 debut.
Unless you're talking about the 1970-74 Challenger.
Or maybe you were thinking of the Mustang, which had a solid rear suspension until 2014. The new Mustang also has 4-wheel independent suspension now.
