That cleantechnica article has quite a few assumptions that the FFE proves otherwise, starting with the very first one:
You have to throw away your frames. All of them. To build an effective, long-range, high-performing electric car, you have to start with something like the Tesla power slab at or below the level of the axles.
Not true, just look at all of the EVs today driving around that are based on existing frames? (FFE, eGolf, I'd even lump the Leaf into this category because its really a derivative from an ICE--yeah I get hate mail from that statement). Unless you are saying "effective, long-range" = Tesla (which I don't agree with at all).
You have to throw away all of your mechanical steering and control systems. Everything is drive-by-wire. Anything else is a waste of space, weight, and time. All of those experienced engineers, all of those solutions that worked, gone. They all assume frames that you don’t have any more, and specific areas for mechanical linkages which are no longer there.
Not true at all: the FFE uses the same steering as the ICE Focus and it works pretty good.
The last two are just silly:
You have to throw away your body panels. They all depend on the frame and the gas tank and the mechanical linkages taking up space that they don’t take up anymore.
You have to throw away your seat mounting systems, and possibly your seats. They expect a lot of wasted space due to motor and transmission drive shaft hump and gas tank that just aren’t there anymore. They depend on a frame which doesn’t exist anymore.
Especially all this talk about "frame": Um last time I looked the only things that were body on frame are pickup trucks and full-sized vans (and even the vans are moving to unibody).
