In 5-10 years we'll see batteries with capacities capable of doing a full race meeting - including practice - on a single charge. They'll be expensive but you'll only need one, and maybe a cheaper pack just in case you want extended practice.

Like AndyS says, the form factor may also change. Maybe it won't be a slab as we're used to, but something integrated into the chassis itself for optimised weight distribution.

Actually, we're not far off that right now.

I also agree with him on dampers. Perhaps there'll be a shift towards self-sustaining kineto-electromagnetic systems and away from fluid based systems. Or even a ferrofluid that can alter its viscosity on demand using some clever filament alignment technology.

Motors might become smaller. Esc units will definitely become smaller, with built in wireless chips enabling remote programming (again, we already have this, but with separate modules).

Edit - Hub motors are already here. Imagine not having a diff to maintain or gear ratios to mess with...

Advances in 3d printing will open up home brew prototype chassis and revolutionize parts distribution. We'll be able to buy a licence for the print files from the manufacturer & print off our own spares, or pay a small premium to have our local model shop print them off for us. And they'll be stronger and lighter than the injection moulded parts we use now!

I'm waiting for wireless charging for my LEAF. That's only a few years away. We'll look back at all these wires and laugh. Imagine a fully integrated setup stand that also contains a wireless charging induction loop & all the charging hardware. That would be sweet.
