It's interesting to compare these two, and not only because they've been measured against each other by pony car lovers in every year since 1966.
The 2015 Mustang GT is a brand new car that starts at $32,925 but the one in the test got all the way up to $46K with the Performance Pack and a whole bunch of luxuries. The 2015 SS is one of the last Camaros built on GM's aging (and heavy) Zeta platform. It also starts higher at $34,500, but cuts under the maxed out Mustang in this case with a price tag of $41,000 with the 1LE handling package and $3,000 worth of extras. The SS with the 1LT alone is $38,000 while the Mustang GT with only the Performance Pack is $35,420.
As far as power and torque goes, the two are roughly the same, but then there's weight. The Camaro is a larger car that has a reputation for being heavy, but in reality, the Mustang gained a few pounds too, meaning that it's advantage is almost gone when you consider the Camaro has 20 extra pound feet on tap.
V8s with 6-speed manuals. Let's hit it!
All I can say is that the 2016 Camaro is supposed to be lighter while its power figure will certainly go higher. If the 2015 Mustang GT with a handling pack can't beat the crap out of a beefed up Camaro at its launch both on the road and on track, Ford might want to start thinking about suspension upgrades.
