The Most Important Improvement Ever
After exactly 50 years, the Ford Mustang got its most important improvement in 2014, which was the independent rear suspension or IRS. Staying true to the muscle car bible, having a live rear axle was outdated for decades, but somehow Ford managed to pull it off. However, for the new, sixth-generation model, Ford introduced IRS and gave the Mustang a chance to fight in the sports car field.
Interestingly, the first IRS Mustangs were the 1999 to 2004 Cobra SVT models. They came with an advanced IRS suspension to handle their improved power and performance. However, for the standard models and regular customers, the first IRS Mustang was the 2014 model.
