RecentlyI drove from Melbourne to Marlo on one charge.. This is 371 km. Carrying around 160kg equipment. I have 19" wheels.. Leaving Melb with 99% I arrived with 20% remaining.so with 5% remaining could have done 436km. Travelled at around 80-90 kph with tyres at 40 psi. Returned from Sydney with 400kg equipment but tyres at 50 psi and managed Gundagai SC to Euroa SC in one hit but speeds more like 100-110 kph on 6% remaining. For anyone asking the question..
