Price Breakdown
The Audi A5 starts from $79,900 before on-road costs, while the BMW i4 opens at $88,900. That makes the Audi A5 the more affordable entry point by $9,000.
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 $87,890 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 A5, as a petrol model, does not qualify.
