The SmartEco’s algorithm works on multiple inputs during the ride. The probability of achieving TrueRange is highest when a single passenger takes the entire ride in SmartEco and the ride is at least 10km long.
Let’s say you start at 100 SOC in SmartEco, you should be able to cover 42.5 Km when you reach 50 SOC and cover 56.67 Km when you reach 33 SOC (And so on)
