Previous car was a beyond race spec VR6 that did 15 MPG average according to the trip, foot down like the R32 I’ve seen as low as 4-5.
My daily is a Skoda Fabia with 240 HP 400LB/FT and according to the the trip computer it does 47 MPG average, although keeping it legal on the motorway can easily get 60MPG.
My 2.1L 16V Scirocco on DTA ECU and ITBs likes to drink.
