Definitely slower than planned (long time ago). Current plans will be inline with what is possible and we don't have insight into that.
Remember when CT was supposed to take on F150 ? The hope was CT would do to truck segment what 3 did to sedan and (more recently) Y to small SUVs. But currently CT is a halo vehicle more like S/X than 3/Y.
May be they need to introduce a "normal" truck to take on F150 like Elon had said once.
Apologies if this seems aggressive to you. But, the way you write, it sounds like you feel this is a done deal, when in fact, it is just beginning.
If any of the 2-3 million reservation holders would have bought an F-150 had there been no Cybertruck on the horizon, then, the CT has already made an impact on F-150 sales, simply because those potential buyers decided to wait for the CT instead.
In five or more years, once the CT production finally gets all of the current reservation holders served, let's look at the F-150 sales over that time and compare it to past sales to determine whether there were a discernible impact on Ford's flagship product.
If the CT reservations continue to ramp up, and remain in the millions while CT production adds Lines 2, 3, etc., what would that mean for the F-150?
There is more to consider before even tossing the idea of "introducing a 'normal' truck to take on the F-150" onto the table.
It could be just as likely that by the time orders for the CT are being filled in weeks instead of years that the CT style could very well be the defacto normal truck. Looking forward to seeing what the legacy OEM trucks look like in a few years.
To paraphrase Elon, what he said was more like, "if the CT is a flop we can always make a more traditional truck"
Is the CT a flop? I don't think so.
