Just returned home from a 500km trip with a fully loaded stinger with 5 passengers and got an average fuel consumption of 8.5 L per 100 km. That’s using standard 9.1 unleaded fuel and speeds of 115 kmh for most of trip. Very happy with those numbers but also noticed that the car is saying it needs a service in 1100 km that’s a service rate of 7500 km not 10000 km as per manual so will have to check with the dealer to see why that’s occurring
