Dual motors are not new idea, and have brought success in the EV-past. Many
years ago when there were few off-the-shelf EV components, Robert Schneeveis
built an Electric race car SnoWhite using two 8" ADC Electric motors:

There are a few EV old timers still around that know of the Tropica EV (aka
Zebra, the original Xebra) shown in Don Johnson's old TV show Nash Bridges:

Don Johnson plugs into electric vehicle maker
Jul 18, 1999 Len Grzanka
Actor Don Johnson has teamed up with a group of Chinese venture capitalists
and American investment bankers to buy Zebra Motors Inc., electric vehicle
manufacturer at the former [Alameda, CA NAS] ...
The new owners have renamed the company Xebra Motors ...
The Model Z Roadster has already appeared on Nash Bridges, driven by the
character Caitlin Cross played by Yasmine Bleeth.
"Don got my character an electric car," Bleeth told the Austin (Texas)
American Statesman. "He was very adamant about it." The car was originally
white, but, she said, "We actually had some guys -- some paint guys -- come
up with some different paint chips to match the exact color of my eyes. So
it is kind of a Yasmine-blue car." ...

The Electric Tropica
we're simply impressed by the Tropica, an electric car built by Renaissance
Cars Inc. of Florida ... A rather loud whir from the motors combines with
the wind in your face to make the ensuing ... Engine control: twin 550 amp
Mosfet controllers ...
Two DC motors mounted on the rear trailing arms provide a peak of 24.5 HP
directly to each rear wheel through a toothed rubber belt ...

One of our EV-Gods (like Otmar), is the aforementioned Bob Schneeveis
who has built many EV creations. One of which was a four belted motor EV
design mentioned below:

I wish Brent all the luck in the world in his attempt! He's a great guy and
has done an incredible amount of work towards getting EVs accepted. I was on
the "Silent Thunder" team at Bonneville when it did the 132 mph run. I
originally built the car and road raced it.
After it was purchased by Michael Murphy he had Bob Schneeveis put in the
four eight inch ADC motors.
It wasn't even breathing hard at 132 mph. The motors were barely warm to the
touch after the run. The car just ran out of gearing.

The fine-folk at Nedra.com have used dual motors, one example:

Today belting multiple motors together is not as necessary because of
inovations/creations like hi-voltage packs powering new motor designs,
including the Siamese motor [

]. There are likely old-timers on the (above) forums for you to talk to
about belting electric motors.
