A detailed look at how two of Australia's most popular Sedans 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.
Price Breakdown
The BMW 5 Series starts from $114,900 before on-road costs, while the BMW i3 opens at $109,900. That makes the BMW i3 the more affordable entry point by $5,000.
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 $126,390 and $120,890 respectively.
The BMW i3 qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The BMW 5 Series, as a petrol model, does not qualify.
