My car weights me 110 kg in drivers place, and 20 liters of fuel in tank:
FL635kg FR605kg
RL 505kg RR545kg

So weight without driver: 2180 kg
NOKIAN HAKKAPELIITTA LT2 215/85R16 115Q STUDDED - Rengaskauppa.net verkkokaupasta

Ordered 215/85R16 Nokian Hakkapeliitta LT2 studded winter tires which have a rolling resistance rating of C (6,8 ≤RRC ≤ 8,0), but these are class C2 tires which means their rolling resistance rating in passenger tire standards c1 is between B class (6,6 ≤RRC ≤ 7,7) . They can also have higher tire max pressure

.

With these my speedo will also be spot on correct.

See page 17 for more details:

On the inspection 3 springs were broken and brake hose needs to be changed. Ordered also eibach 30mm lowering spring kit to solve that problem.

Audi has made a e-tron Quattro concept which can go as low as 0.25 Cd. (0.27 for the hydrogen version)
