Sounds like the car is tuned. What kind of fuel economy are you getting?
That’s well above average for elevation change driving. I’d suspect a tune, that’s likely why you’re hitting 1 bar.I drive the car with 10liter/100km (62,13 miles). That should be 23,5 miles per gal. But i live in a mountainous area. My d5 s60 consumed with the same road profile 7l/100km of Diesel.
