My Ecotxec is a Skoda Octavia 1.9 Tdi the same car as a Jetta TDi (VW Bora in Europe) and I'm very impressed with my >50 us mpg last fuel fill up.
Both are made with the same engeenering using A4 platfromf PQ34

I have an airdam , upper and lower partial grill block. I have tried lexan smooth wheelcovers but they are ot fitted now because they are ugly compared with my alloy wheels or steel wheels i used to have with aero hubcaps. They gve me around +3 us mpg.
But I'm very impressed with your 60 mpg at more speed than me.
Next week I'm trying the 5th gear swap to 0.681 because I have 0.769 in my 1.9 TDI AHF 110 cv VGT engine.
I'm using Michelin Energy SAver+ Tires 205 55 16 rated B rolling resistance (rr 6.5 to 7.7 kg force per Tonne) and A wet grip (about 1.35 G lateral grip). Using European Tire Label.
I think I'm able to raise fuel economy to 60 mpg when I swap 5th gear, is it right?
Coasting it's far better now with airdam, front grill partial block (I can't block full grick because Valencia's weather it's like California's).

I lowered also my ride 2 cm (0.79 in) using Skoda Octavia vRS spring and shocks (the same as Seat Leon Cupra ones, same VW platform spanish automaker), I dont have 1.8 Turbo petrol engine with 180 bhp but drives the same, ahahah. Also I fitted upper and lower front strut bars from an Audi S3 (same A4 VW platform). If they are good for a 1.8 T with 225 bhp, they are good for ecodriving, ahahaha.
My car has only VW original parts inside but in a custom way.
