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 Audi RS3 starts from $101,515 before on-road costs, while the BMW i4 opens at $88,900. That makes the BMW i4 the more affordable entry point by $12,615.
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 $111,667 and $97,790 respectively.
The BMW i4 qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Audi RS3, as a petrol model, does not qualify.
