If unsprung mass has such a great impact on FE, I'm left wondering why Volvo changed their regular alloys (7 to 7.5 kg for 15") to the more streamlined Lybra rims that weigh 9.1 kg (15").

So maybe the aero-improvements can make up for the increase in unsprung weight ?

(See their accessories page for info on these wheels.)
