The reason the Focus is slow isn't that the electric motor isn't that quick, its that the traction control limits the acceleration (e.g. its a software issue, not a hardware issue). If you give the Focus a slight rolling start (like 5+ mph) it is darn zippy--almost like you avoid some condition in the software that limits the torque when starting from a stop.
You cannot deny, however, that there is going to be a noticeable difference in acceleration between a 3640 lb car with 143 hp and 184 lb-ft of torque (FFE with 25 lb/hp, 19.73 lb/lb-ft) versus a 3,540 lb car with 200 hp and 266 lb-ft of torque (Bolt with 17.8 lb/hp, 13.38 lb/lb-ft). That nearly 30% decrease in the power to weight ratio easily accounts for most of the difference in the acceleration times.

No doubt that the Focus can feel pretty spritely around town, but by comparison, the Bolt feels downright quick and the official acceleration times bear that out. 3.5 seconds difference 0-60 is a pretty dramatic gap. I have no doubts that the 5-60 times would show a similar gap as the Bolt suffers the same problem of traction off the line as the Focus and GM has been equally aggressive with the traction control.

Never said that the FFE was going to be faster than the Bolt and wasn't implying that at all.

Just wanted to point out that there is more to the FFE's "lack of performance" than just the electric motor.

Having just driven a "basic" Model S around for the weekend...they are all slow! LOL

What is the top speed of the Bolt?
GONE - 2015 FFE, Magnetic with leather interior, debadged & tinted
38,500 miles (since May 2015), average 246 Wh/mile

REPLACED WITH - 2018 Tesla Model3, LR RWD, Obsidian Black
11,000 miles (since Nov 2018), average 235 Wh/mile

I still contend that the "software issue" you are referencing is only a small contributor to the overall loss in performance compared to the basic power to weight ratio. For instance, another car with a similar 25 lb/hp power to weight ratio is the Toyota Prius, which also sports a similar 10.5 second 0-60 time as the FFE.

That said, yes, the Model S does make them all feel slow, but that's a moot point given how much of a price gap we're talking about.

Thanks.....a bit better than 85 on the FFE. I find myself bumping that limit pretty frequently on the LA freeways....

Height wise I think you'd be fine as the Bolt is tall like a C-Max, it really depends on how "wide" you are. I would recommend finding one at a dealer and sitting in it. It only takes a few seconds to know if you're ok or not.

Given that you're tall and "skinny" LOL I think you'd be fine (I'm shorter and heavier than you are).

How was your experience regarding the Chevy Bolt rear cargo storage space vs the FFE?
I'm also anxiously awaiting the upcoming Hyundai Kona EV later this year, looks like it could give the Bolt competition.
