How is the fuel economy at high speeds?

I've managed to run up to 7.3.

City areas are not congested between 10 to 11.

I'm sorry, I can't assist with that request.

This car should start at 100k, I guess. I heard it's not fuel efficient, so I'm hesitant to buy it.

2017 model with four-wheel drive, seating for five. Drove on the highway at speed limit for 1850km, with an average speed of 89 km/h and an average fuel consumption of 10.3L/100km.

I've driven the 8.5.

If you want to save on fuel, don't buy this car.
