MG IM6 Premium 75 vs Smart #1 Premium: Australian charging access and family fit

MG provides an Australian IM6 model page and configurator; smart provides Australian #1 model and configuration pages with a Premium line. These are local sales routes for the cars under consideration. They do not confirm that a dealer has your required VIN, colour or delivery slot. The versions here are the IM6 Premium 75 RWD under MG's MY25 technical documentation and the smart #1 Premium RWD. They are not the IM6 Performance or smart BRABUS.

The MG configurator opened on a NSW/private-buyer example. Its Premium card displayed $60,990 reduced to $57,990, with $3,000 cashback already included. That is a conditional displayed example, not a national cash quote. The smart Premium card displayed from $53,900 plus on-road costs; the $49,900 plus on-road-costs entry price belongs to Pro+. Comparing $57,990 driveaway in one state with $53,900 before on-road costs would hide a material difference in what is included. Obtain a state-specific total, allocated specification and delivery commitment from each seller before calling either car cheaper.

The Australian IM6 brochure's Premium 75 column gives a 75 kWh LFP battery, rear-wheel drive and 217 kW maximum motor power. It labels the platform 400 V IGBT. Its 450 km range is WLTP combined. The same table contains the 100 kWh Platinum and Performance specifications, which have different battery chemistry, platform and charging figures. The 555 km, 396 kW DC and 15.2-minute headlines associated with those versions must not be assigned to Premium 75.

smart's Australian Premium material gives a 66 kWh battery, rear-wheel drive, 200 kW and 440 km WLTP combined. The configurator carries #1, #3 and #5 data and several grades in one document, so a generic tooltip or a neighbouring card is not automatically a Premium specification. We use the local #1 Premium line and keep its scope explicit. Neither source establishes an equivalent gross-versus-usable battery-capacity basis for an energy-cost calculation here.

The 450 km and 440 km figures share a WLTP label, but they are manufacturer laboratory figures, not measurements of an Australian winter journey, freeway run or loaded holiday trip. A ten-kilometre difference on those labels does not establish a practical range winner. Ask about the route and charging stops you actually use, and test the car in a representative load and climate rather than treating either label as a guaranteed distance.

MG lists an 11 kW onboard AC charger for the Premium. smart lists 22 kW AC capability for #1 Premium. This can matter when you regularly leave a car at a suitable workplace, destination or home charger. It is a ceiling set by the car, rather than power that every socket can supply. Ergon Energy's network guidance identifies a dedicated 22 kW charger on three-phase premises and calls for assessment of site demand, connection capacity and any necessary upgrades. That supports the supply condition; it does not approve an installation at your address.

Check the actual charger power available to one connected car, whether it shares capacity, your cable and the time you can reliably stay parked. At home, have an installer confirm the supply and proposed equipment. If your regular connection cannot provide 22 kW, do not assign the full advertised AC advantage to the smart. Conversely, if a compatible 22 kW destination is dependable, put that access into the buying decision rather than judging the two cars solely by their DC headline figures.

For DC, the IM6 Premium brochure gives 153 kW maximum and an estimated 20 minutes from 30% to 80%. Its laboratory-data footnote warns that temperature, vehicle condition and station status affect the result; MG's model-page charging note also describes standardised testing on a 350 kW charger. smart's local Premium card gives 150 kW and 30 minutes from 10% to 80%, while its model page says under 30 minutes for that interval. A generic configurator tooltip also says 220 kW, conflicting with the selected-line card and model-page 150 kW. We retain the selected Premium 150 kW basis and ask the seller to resolve that wording, rather than upgrading the car to 220 kW.

The two advertised charge times cover different starting states of charge. They cannot show that the MG is ten minutes faster for the same top-up. Charger availability, battery temperature, arrival charge and the charging curve remain unmeasured here. Plan a typical stop around the actual interval you need, with a backup location, instead of treating either peak as a sustained rate.

The IM6 brochure gives a 4,904 mm body length and 1,988 mm width for the model range. That makes your garage opening, the space to walk past the parked car and door clearance worth checking before booking accessories or delivery. The Premium specification lists four-wheel steering, but a manoeuvring aid does not reduce the physical body width. Try the car in the sort of narrow entrance or parking bay you regularly use, with room to open the doors and reach a child seat.

MG quotes 665 litres with the Premium's seats in place and 1,640 litres folded. Those are manufacturer figures; we have not established a matched smart measurement protocol or usable family-load ranking. smart promotes a flexible cabin with a sliding rear bench. Moving a bench changes the space available for passengers and luggage, so try it in the position your passengers need. Bring the same pushchair, child seats and everyday bags to both demonstrations and leave the front seats set for the adults who will drive.

Ride comfort also needs the right demonstrator. In the IM6 technical table, air suspension and continuously controlled damping are absent from Premium, optional on Platinum and standard on Performance. A road test or showroom demonstration of Performance therefore cannot establish the Premium's ride. We have not conducted a matched ride, noise, rear-seat or child-seat test of these selected cars. Choose the seating position, visibility, suspension feel and access that work for your household after trying the correct grades.

The MG configurator's new-vehicle offer applies to qualifying vehicles sold and delivered from 1 to 31 October 2026 through participating dealers, while stock lasts. Its exclusions include fleet, government and rental buyers. The displayed price already incorporates the $3,000 cashback; subtracting it again would invent a discount. An order date alone does not establish that the required delivery window or the allocated car's eligibility will be met.

The separate $500 EV Accessories Bonus has its own qualifying new/select-demonstrator conditions. It offers eligible accessories ordered with the car or a $500 price reduction instead. Those alternatives are not two simultaneous benefits. Do not assume the alternative reduction has already been granted, or that every combination of cashback and accessory benefit applies to your vehicle. Ask the dealer to identify the qualifying car, each benefit and the final amount payable on the same written quote.

MG describes the driveaway example as including registration, CTP, estimated stamp duty and dealer delivery on the selected basis. smart's Premium figure is plus on-road costs, so request those items and any colour, option or delivery charges explicitly. The final postcode, state, private/fleet status, build and delivery date can change the comparison. No personal quote, eligible VIN, deposit or confirmed allocation was obtained for either car in preparing this article. The current cash gap therefore remains unknown.
