The tail of this vehicle is not the same as the base pressure recovery "box/cavity" referred to in the linked PDF.

For that particular mod to work, the "box/cavity" needs to be inset from the trailing edges of the vehicle, and extend out far enough to promote flow re-attachment, I believe, with entrained vortices in the "steps" between the sets of edges.

Okay, we now have a third SIM-Drive prototype - the SIM-CEL:

Sim-CEL has Tesla-quick performance, lasers for high beams







Here's a slideshow of 15 pictures: SIM Drive to start mass production of EVs in Malaysia | Responsejp (Eco-car electric )

Here's a shot on the hatch area:

Cool.

Incidentally, did you follow the comments on ABG after yours? Steve Fambro, still fighting the good fight.

Yes, Steve is keeping on top of these things. His new business is doing well, and the NDA is up on his Aptera days, I think.

This version most definitely looks the best in my opinion. But this one from what I can tell is geared for performance with only 2 seats etc. All of them regardless of looks is impressive I would agree Neil!

Nice post and thanks for sharing

All the SIM-Drive cars have no gearing whatsoever - they use in-hub direct drive electric motors. They are 4 wheel drive, and have traction control, and lotsa' regenerative braking, too.

Kind of pointless to be all wheel drive. Prob would go farther with a simple fwd or rwd depending on engine location won't you think?

Johnathan,

There is no engine in any of the SIM-Drive cars. They are all electric and they all use electric hub motors; hence the total lack of gears, and the oodles of torque.

Sorry i know they are hubs I more meant get rid of 2 of the hubs and just increase the output on the two remaining.

I'm not sure that electric motors lose efficiency by being too powerful? They don't idle, and when they have large(r) diameter armatures, they increase in torque with the same electrical input, because of the physical leverage. They actually increase in efficiency (a bit) when the armature is larger because then you can fit in more coils, which improves the geometry.

With 4 wheel drive, you get both better acceleration, you get better regenerative braking. You do not have to power the motors equally all the time. With direct drive, you have no gearing losses, and with in hub motors, you don't even have U-joints or CV-joints; though you do increase the unsprung weight.
