Mercedes-Benz EQS Price Australia: The New Longest-Range EV, With a Catch

Australia has a new longest-range electric vehicle, and it comes from Mercedes-Benz. The updated EQS400 went on sale locally on September 10, 2026, claiming an official 810km WLTP range, just enough to edge out the BMW iX3 for the title.

There is a genuine catch worth knowing before you get too excited about that number though.

Here is everything confirmed on Mercedes-Benz EQS price Australia, range and what changed.

Key Facts Panel

• Price: EQS400 from $184,900 before on road costs, a $37,400 saving compared to the outgoing all wheel drive EQS450

• On sale: since September 10, 2026, Australia's only confirmed EQS variant for now

• Official range: 810km WLTP, currently the longest official rating of any EV sold in Australia, ahead of the BMW iX3's 805km

• The catch: that 810km figure is based on European spec 19 inch wheels. On the 21 inch wheels fitted as standard in Australia, real world range drops to around 788km

• Power and torque: 270kW and 505Nm from a single rear mounted motor, a shift from all wheel drive to rear wheel drive compared with the outgoing EQS450

• Charging: up to 350kW DC on the new 800 volt architecture, adding around 320km of range in roughly 10 minutes under optimum conditions, or up to 175kW at 400 volt stations

• Do this: if outright range is genuinely what you need, the EQS400 delivers it, but budget for the 21 inch wheel real world figure of around 788km rather than the advertised 810km when planning long trips.

• Don't do this: assume Australia is getting the global range leader. The longer range EQS450+, rated up to 925km overseas, has not been confirmed for local sale.

What Actually Changed

This is a genuinely significant update, not a styling refresh. The new EQS400 moves to an 800 volt electrical architecture, a larger and more efficient 112kWh usable battery, and a two speed transmission designed to balance strong standing start acceleration with highway efficiency.

Mercedes-Benz has also added an optional steer-by-wire system with an aircraft style steering yoke, available as a $7,500 package on top of the base price.

The drivetrain change is worth understanding clearly. The outgoing EQS450 was all wheel drive. The new EQS400 is rear wheel drive only, with a single motor producing 270kW and 505Nm, up 5kW but down 295Nm on the old car's combined output.

That's a genuine trade off, more range and a lower price, in exchange for losing all wheel drive traction.

The Range Figure Worth Understanding Properly

Here is the detail that's easy to miss in the headline "810km" claim.

That figure is achieved on the smaller 19 inch wheels used for European testing.

Australian delivered EQS400s come standard on larger 21 inch wheels, which increase rolling resistance and aerodynamic drag.

On those wheels, the realistic range is closer to 788km, still genuinely excellent, but worth knowing rather than assuming you'll see 810km in daily driving.

Detail	EQS400 (Australia)
Official WLTP range (19 inch wheels)	810km
Real world range (21 inch wheels, as sold locally)	Around 788km
Battery	112kWh usable
Power/torque	270kW/505Nm
Drive layout	Rear wheel drive
DC charging	Up to 350kW

How the Price Cut Changes the Calculation

At $184,900 before on road costs, the new EQS400 is $37,400 cheaper than the outgoing EQS450, and sits $79,300 below the cheapest petrol powered S-Class, based on European market comparisons Mercedes-Benz has highlighted. That's a meaningful repositioning for a flagship electric sedan, even if it means accepting rear wheel drive only for now.

Buy or Avoid: The Verdict

Buy if: you want the longest officially rated range of any EV currently sold in Australia, you don't need all wheel drive, and the price cut compared to the outgoing EQS450 makes the flagship sedan genuinely more accessible for you.

Avoid, for now, if: all wheel drive traction matters to you, or you specifically want the global range leading EQS450+, which Mercedes-Benz Australia has not confirmed for local sale.
