* Take an Ioniq 6. * Rip everything comfy (except the front row) out. * Stuff the rear with extra batteries. * Use the smallest tires still able to carry that weight.

I would bet 10k€ that would surpass 1000km as a two seater with the same average speed (102.?? km/h =~ 63.5 mph)

The unchanged road worthy version is already good for 430-450miles @90km/h under optimal conditions.

Using ultra-slim tires (drag reduction) that can hold that weight would lead to an estimated 500miles/810km range (ChatGPT says 505miles best case). Thats _before_ adding a custom battery pack.

For a 1000km+ run that would mean adding another ~20kWh (97kWh total, ~110kg extra) -- that's not exotic. And easily doable without modification of the chassis.

On a real highway or on a test stand ? /s

The question is how much of this "single charge" is available in real conditions.
