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 Mercedes-Benz GLC starts from $89,900 before on-road costs, while the Polestar 3 opens at $99,900. That makes the Mercedes-Benz GLC the more affordable entry point by $10,000.
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 $98,890 and $109,890 respectively.
The Polestar 3 qualifies for FBT exemption as an electric vehicle, which can dramatically reduce the effective cost for novated lease buyers. The Mercedes-Benz GLC, as a petrol model, does not qualify.

Drivetrain
The Mercedes-Benz GLC uses a Petrol producing 150kW and 300Nm of torque, sent through a automatic to a AWD layout. It covers the 0-100km/h sprint in 8.2 seconds.
The Polestar 3 responds with a Electric Motor making 245kW and 480Nm, paired to a single-speed fixed gear driving the rear wheels. It gets to 100km/h in 6.5 seconds.
The Polestar 3 has the clear power advantage at 245kW vs 150kW. In the real-world sprint, the Polestar 3 is 1.7s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
