I hope it's not a 3 belt car.. 3 belt, in my opinion, is a compromise as a result of the chassis layout. I have yet to see an efficient 3 belt electric car. Every 3 belt car I have seen had extra drag in the drive system which isn't ideal for electric racing.

I am hoping for a 1 or 2 belt solution.

The chassis cuts for diff/spool are so narrow it would make sense to be single belted, but the shafts in oposing directions are boggling me. If they avoid using 3 belts, this is going to be very interesting.

The motor appears to be mounted higher than usual too, but I'm sure it's only a false impression.

The motor mount appears to be designed to have a belt run between the mount and motor face (connecting the two layshafts with a third belt). So centred diffs with a very short front belt which might make the car easier to drive.
The motor must be mounted with the 2 o'clock and 4 o'clock holes.

Like this.


Blue belts are on the centreline, black is offset towards the the motor side, and runs through the bulkhead. Does look like clearance on the mount indicates larger pulleys, at least for the middle belt.

I think there is a part missing to fix the motor. What would be the interest to use a third belt if you are not centering the motor at maximum?

Might be a dual spur design.

Three belt.
The motor slots dont go far enough into the center and the mount is spaced thicker where it mounts.

So a spur gear of some kind on the end of the left side layshaft? The shaft looks longer there and the mount has more reinforcing.

Maybe the thord belt runs around the motor? That might be reason for the large pulleys.

Huge lump of aluminium in the middle of the car = too stiff
Three belts = inefficient
Barely any pinion clearance = modified motors only

Looks like it will be a massive success!

Looking at how the motor mount lines up on the chassis plate, there should be plenty of flex in the front half which seems to be the working trend. Pinion clearance is indicated by the slotted screw holes... looks like enough range to me. If it's done right, 3 belt efficiency will be okay... maybe not the ultimate VTA car but I'm sure that isn't the market they are going for.

i believe it is either 3 belts or some sort of pulley / support system to allow for 1 belt

happy to see at least some new / renewed thinking within TC designs --- and not just a copying of others.
