Tietokonesimulointi osoittaa vertailtujen pankkotyyppien suuren kulutuseron. Laskentamallinnus on vertailukelpoinen kenttäkokeitten ja käytännön kokemusten kanssa.
10.03.2017 0.30 Alla olevissa taulukoissa on lihavoitu 1 kpl,6kpl,10kpl ja 12kpl pankon kulutuslukemat 80 km/h ajonopeuksilla. Aerosimulointivertailu on tehty tyhjänäajossa ja identtisissä ajo-olosuhteissa XXL pankon ja ALU pankon välillä.
Vertailupankkojen otsapintojen koko ja niitten ilmavastusmuoto
aiheuttavat pankkojen kulutuserot.
Vertailuyhdistelmien kulutusero 4% - 8%.
Vertailuyhdistelmien kahdentoista pankon kulutusero on tasaisella 70 km/h ajonopeudella kahdeksan litraa sadalla , ja jos ajosta puolet on kuormattuna ajoa, on kulutuseroarvio noin viisi litraa sadalla. Simuloinnin antamista tuloksista voidaan päätellä vertailupankkojen kulutuseroksi keskivertopuunajossa ajonopeuden,maantieajomatkan ja kuormauksen osuudesta riippuen neljästä kahdeksaan prosenttiin.

Taulukon kulutuslukemat ovat simuloidut kahden eri pankkotyypin yhdistelmille tyhjänäajossa 60/70/80/90/100 km/h tasaisilla ajonopeuksilla ja identtisissä ajo-olosuhteissa. Pankkojen vaikutusta tyhjänäajokulutuksiin on arvioitu vertailupankoilla lisäämällä yhdistelmään pankkoja pankko pankolta paino- ja ilmanvastuslisineen (0 kpl - 12 kpl).
