e-REX​

The best of both worlds

If you could choose your dream ICE for extended range applications, what would that look like?

It would be light and small, to leave extra room for the batteries and motors.
It would have 0 vibration, so it does not interfere with the smooth electric experience.
And since electric vehicles are expensive enough as they are, it would have to be simple and cheap to manufacture.

In other words, the ideal engine for range extender applications would combine the efficiency and low emissions of a state of the art 4 stroke engine with the simplicity, compacity and power of a 2 stroke one.

e-REX

The true range extender

The e-REX is all that and more: more efficient than a 4 stroke engine while smaller and twice more powerful than a 2 stroke one.

With no crankshaft, no valves, no camshaft or cylinder head, the e-REX is 55% smaller and 70% lighter than any 4stroke ICE.
Nothing but clean efficient power.

e-REX

No Vibration

And on the subject of unwanted things we removed, we got rid of vibration.

The e-REX’x moving parts do so reciprocally and in equilibrium at all times in all 3 planes, cancelling out one another.
The result? Have a look

With no crankshaft, no valves, no camshaft or cylinder head, the e-REX is 55% smaller and 70% lighter than any 4stroke ICE.
Nothing but clean efficient power.
