I have covered 900 enjoyable miles in mine since taking delivery. I haven't yet tried Sport mode with the drive select and gearbox settings as it's early days still and in comfort mode I can feel that the engine is straining at the leash. The long term memory on the DIS shows 37-odd mpg which tallies with the figures I've got from brim to brim calculations. The sales guy warned me not to expect too impressive economy while the engine is bedding down. That might have been sales patter, but we'll see. Once I start using sport mode I expect the consumption to worsen - but the fun factor to increase!
