Hello, I have Just bought 2006 Cayenne v6 3.2!

I love my car but Im worried about fuel consumption! My car eats 20 liters each 100 km (Urban-75%; Extra- 25%) and Im driving very honest.
Is it normal fuel consumption or I have to check my car at dealers to check mistakes in ECU or so on?

P.s. My car has 39000 km!

Thanks

 

Sounds a bit excessive, but not tooout of lineif its mostly urban driving as you say and you tend to want it to accelerate quickly. It is a heavy vehcile with a lot of friction losses from all its drivetrain machinery, and the engine, at 3.2 liters, is on the low side displacementwise for the vehicle's weight: it has to rev a lot and work hard to move it.
