Steve, though I'd rather not
Steve, though I'd rather not rant, some things need to be said. The Camaro is available in many forms and the Z/28, until the GT350, beat any resale Mustang sold by Ford in several aspects, including road course race prowess. It was just plain faster on the race track. On the 1/4 mile, the Mustang has been top dog for many years and that may continue, but for 2015, there is no road legal Mustang that is certain to be quicker than the ZL1... except maybe the same GT350, which we can't actually get yet. Even then, it's gonna be close. In a nutshell, it's not just cut and dry as to which is the better performer.
As to the "dinosaur" pushrod V8, that's a total fallacy any which way we look at it. 1st off, the pushrod V8 design is roughly 45 years... YOUNGER... than the OHC design, which was invented by 1902. Dual OHC has been around since at least 1912 ... that's more than 100 years for either and as far as I can tell, the OHV "dinosaur" was 1st put to use in 1949... The patent was filed for by Arthur Chevrolet in 1928 and he got it in 1930. So we could say they've been around that long. Either way, they're "newer" than OHC and DOHC,
Not only that, the current "LT" series isn't your fathers Oldsmobile, by any means. The engines are aluminum vs iron from way back, They're more efficient than ever, utilizing that "old school" cylinder deactivation... oh wait, that's not old. They also all have Direct Injection these days. They also have variable valve timing... these are hardly "Jurassic" and shouldn't be referred to as "dinosaur" based on the facts.
The 2016 Camaro SS will be quicker than the 2015(and apparently 16) Mustang GT. The V6 model is also likely to be quicker than V6 Mustang, but the 4cyl will likely fall notably short.
It's probable that the only Mustang "winning" in V8 form will be the GT350 and while I personally have no problem with that(actual sanctioned racing favors Mustang) because the correct base is more important than the stock win, it's only going to get more competitive for 2017 and 18, at the rate things are going. The end result is, customer win. The real problem with Camaro is the same as it's been since 2009 ... outward visibility. They perform fine and they're rather efficient. Of course, rear passengers won't care about any of that, the other drawback, but Mustang isn't much better there.
