The 1988 Mustang's weight was closer to 3,200. The current one is about 3,
700. Why? Capability and features. The 1988 Mustang didn't have the cha
ssis to support the 2015's 430 horsepower or .96 g's of grip. The 1988 als
o didn't come with 4-wheel disc brakes, IRS, a stout transmission, and huge
stream roller wheels and tires. Add those features to the 1988 Mustang an
d you'd quickly have 3,700 pound Mustang.
