With electrical drivetrains making custom cars more feasible (easier to obtain for small car makers, simpler to integrate into a custom setup), we can hope for more of such design becoming reality in small numbers.
This concept car probably really was just designed to be maximal crazy :), but I think it is a great concept. It would only require a few small changes to become a really cool and modern car.
Small shops in the US regularly turn out custom made vehicles with modern engines.
Lots of them use parts out of junked cars, but also "crate engines" are a thing, you can just buy a powertrain from any number of suppliers (for instance, GM: http://www.chevrolet.com/performance/crate-engines ).
And then there are specialist machine shops that build linkages and such to go between whatever components, at whatever length.
I imagine safety regulations and cost are the big blocker for small scale manufacturing.
People have been doing EV conversions since forever.
If electric becomes a viable alternative to remans and crate engines the OEMs will just offer a "crate engine" electric drive-train that bolts where an LS or SBC would go and the stuff needed to make it plug and play.
You don't need a custom vehicle, just an S10 with a blown motor.
I was responding to the other poster's assertion that electric drivetrains will be easier to obtain. I don't see how there can be anything that is really meaningfully easier than ordering something out of a catalog.
