Coming Clean

Think you've been anxious for your first look at the '15 Mustang? Consider the guys who are building it. During the first press preview, Ford management, marketers and engineers were all but bursting to talk about their new baby.

Like school kids at their first dance, the press and Ford people were awkwardly shy for the first moment, then fairly gushing once it sank in that, yes, they really could talk about the new Mustang to people outside their work group. There was so much to tell, so much held back that the exchanges came in bursts, the subject pinging from the minutiae of the alloy in the brake calipers to macro demographics in 30 seconds.

And don't think there aren't serious sanctions against speaking before the official release. More than once at the reveal a Ford employee would slow in mid-sentence, tensely searching for the right words, then suddenly relax, saying, "Oh, that's right, we can talk about this now."

We're all used to the odd diplomatic dance that takes place before a car is announced. The press probes, the engineers and marketers mince words, all but speaking in tongues to say something without revealing anything. But when the dam finally breaks on a car as significant and as anticipated as a new Mustang, the relief is real enough to carry in a backpack. One that you can take off, that is.


Ultimately, even after our limited exposure to it, we are more sure about this new Mustang than any other in our 26 years of professional experience with the marque.


New Rivals

Ford has apparently declined magazine requests to supply '15 GTs for Mustang vs. Camaro stories (don't worry, such stories will end when the sun quits rising in the east), and David Pericak was queried as to why.

"Camaro has their car, they tune it and develop it the way that they do and... their customers love it and there's nothing wrong with that. But if you want to better yourself... that's why we took Porsche 911s and, you know, we had some pretty high aspirational vehicles along with us on the development— because, as Raj and the rest of us say, we want to raise the chinning bar. It's not that we discount them... we believe we need to look beyond that [the Camaro] to make ourselves better.
