There's a more text/info after the link, but here're the stats (I wish they'd have included something in the '85-90 range):

1964.5 Ford Mustang Convertible – 8.2 seconds
1967 Ford Mustang GT – 7.3 seconds
1968 Ford Mustang Coupe – 5.4 seconds
1969 Ford Mustang Mach I – 5.7 seconds
1971 Ford Mustang Boss 351 – 5.8 seconds
1974 Ford Mustang II Mach I – 12.2 seconds
1976 Ford Mustang II Cobra II – 8.9 seconds
1980 Ford Mustang Cobra – 10.8 seconds
1982 Ford Mustang GT – 8.1 seconds
1996 Ford Mustang GT – 6.6 seconds
1999 Ford Mustang SVT Cobra – 5.5 seconds
2003 Ford Mustang Mach 1 – 5.2 seconds
2005 Ford Mustang GT – 5.2 seconds
2010 Ford Mustang Shelby GT500 – 4.6 seconds
2011 Ford Mustang GT – 4.6 seconds
2013 Ford Mustang Boss 302 Laguna Seca – 4.2 seconds
2013 Ford Mustang Shelby GT500 – 3.5 seconds
2015 Ford Mustang GT – 4.5 seconds
2015 Ford Mustang EcoBoost – 5.2 seconds
2016 Ford Mustang Shelby GT350 / GT350R – 4.3 / 3.9 seconds
2018 Ford Mustang GT – 4.3 seconds

I think it's interesting to trace a vehicles performance over this range of time, and as stated somewhere in the article, this is a fairly valid comparison (more than it would be with something like the 911) since the pony cars or muscle cars sort of targeted this sort of performance unlike something like the 911 that was not about straight line acceleration.

It would be interesting if the motor size, power and vehicle weight were included.
