How does one explain such a big difference in expected range, as published by NRCan? With 20 inch summer tires: 698 km. With 20 inch all-season tires: 616 km. The latter is worse than all other tire and size combinations, even 22 inch. Did they achieve the 698 km using steel train wheels?

The iX3 Neue Klasse is not yet available for test drives here in Canada, but I am trying to nail down the spec ahead of time. The Luxury package (C$4900) includes the upgraded audio. It is the only option in that package I am interested in. Based on previous BMWs, how big is the improvement from the base audio, for a non-audiophile? Worth $4900?
