Audi RS6 vs BMW XM
A detailed look at how two of Australia's most popular cars compare on price, running costs, safety, and everyday livability.
Specifications and pricing correct at time of publishing. Prices are RRP before on-road costs unless stated otherwise. Always confirm with the manufacturer or dealer before purchasing.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.
Price Breakdown
The Audi RS6 starts from $241,500 before on-road costs, while the BMW XM opens at $309,900. That makes the Audi RS6 the more affordable entry point by $68,400.
Once you factor in stamp duty, registration, CTP insurance, and dealer delivery, expect to add roughly 8-12% on top of the RRP depending on your state. That puts estimated driveaway prices in the ballpark of $265,650 and $340,890 respectively.
The BMW XM qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Audi RS6, as a petrol model, does not qualify.
Over 5 years, the running costs favour the BMW XM by roughly $13,745 in fuel alone.
