Superb IV: Excellent
I've been using this engine for 3 months, driven 3700 km. I know the car is heavier than the previous version, with many more cameras and sensors, so the fuel consumption is expectedly higher. However, there's no chance of achieving 5.5-5.8 L/100km. I reached 5.8 L during a drive from higher to lower terrain, a 20km route. The return journey immediately jumped to 8 L/10km, averaging around 7 L/100km. On the highway at speeds of about 130-140 km/h, the consumption is 7 L/100km. For me, the computer has shown 7.6 L/100km from the start, and I drive (as my wife calls it) like a retiree.
