GAC T9 Robotruck (Pony.ai Gen-4)
A truck that drives itself, on GAC's T9 electric tractor: 402 kWh, 330 km and 1.1 kWh/km, as Pony.ai's brochure prints it. What it would cost to run in Europe cannot be worked out yet: no price, no European approval, and Pony.ai only plans to enter Europe within two years.
