Hi guys! Yesterday I bought a 2001 Audi A2 1.2 TDI 3L here in Sweden. It is even more fuel-efficient than a VW Lupo 3L. Maybe because the whole body of the car is in aluminium just like the Tesla. There are only 6500 left in the wild in the whole world of these 1.2 TDI Audis, so I am pretty amazed I could find one. I will fill it with Biodiesel the next time I refuel and it should get equal mileage as with standard diesel.
