I heard similar comments about small turbo engine paired with manual tran. The dealer where I bought my mustang actually told me he prefer auto in the EB mustang because you don't lose boost between gears.
3.5EB is a very viable alternative for the coyote, and it is likely to happen in the next generation.
Just like when Audi/BMW/MB started to used turbo 4 to replace their base 6 cylinders.
With stock power level and stock shifter, I found that the transmission becomes smoothier after 12k miles, it feels almost like the linkage is no longer too tight and easier to put in gear. For the first a first thousand miles it was a little notchy espcially after cold start.
Maybe sometime...
with 3.31, you won't need to shift as much. And above 60mph the car is comfortable in 6th gear, meaning the overall gearing is not too tall.
I don't think the car is sluggish with 3.31 as someone states. Of course, at the same rpm, 3.73 is quicker. But at the same mph, you could be one gear...
Sounds reasonable that Ford would continue updating their turbo V6. Then whatever replaces 3.5EB may go into S650 GT.
The most probable scenario would be a turbo V6 replaces coyote. FI V8 is an overkill for Mustang GT given its market position and may only used for S650 GT500.
It's hard to imagine that Ford GT (the halo car) is using a EB3.5 (more than 600hp) while Mustang GT deserves a twin turbo V8. Ford does not need a v8 to make the power that's suitable for a mustang GT. I imagine when the time comes, it will just be like BMW 328i going from NA I6 to turbo 4...
Realistically, next gen Mustang GT will probably use 3.5L ecoboost making ~450hp.
Twin turbo v8 for Mustang GT is just wishful thinking, and it makes little business sense.
I am still curious about the improvement on throttle response and low-end torque. I haven't seen any clear indication/review that there are clear improvement in those two areas.
