Dolphin Essential vs Mazda3 G20 Pure hatch: Australian offers and the charging decision
Dolphin Essential has the lower advertised driveaway reference; Mazda3 G20 Pure keeps petrol refuelling. Choose by the charging, luggage and travel routine you can actually use, with both offers checked for your purchase.
A charging space can matter more than the advertised price gap
I would try the BYD Dolphin Essential first if you can charge where the car normally parks and its range, seats and boot cover the household's routine. Its advertised $28,888 driveaway campaign is below Mazda's from-$32,990 Pure reference, so an electric hatch does not automatically mean paying more to buy the car in this particular shortlist.
I would put the Mazda3 G20 Pure hatch first if access to charging would mean a regular detour, uncertainty over a shared charger or a difficult installation. It also deserves the first appointment if unpredictable longer trips make quick petrol refuelling more useful to you. That convenience can justify a higher purchase quote; it does not establish that petrol will cost less to run.
The two published references are $4,102 apart. This is the arithmetic difference between the advertisements, not your guaranteed saving: confirm campaign eligibility, paint, the actual driveaway quotes and any charging work before spending it elsewhere. CathayEV has not conducted a joint road, charging or family-loading test.
Essential and G20 Pure hatch are the versions being compared
The Australian Dolphin Essential is the front-wheel-drive battery-electric model with a 44.9kWh Blade battery and 70kW motor. The model page's prominent 150kW and 427km WLTP figures belong to Premium, as its footnote says. Those do not turn the Essential campaign car into the higher-powered version.
The rival is the Mazda3 G20 Pure hatch with a 2.0-litre petrol engine and six-speed automatic transmission. Mazda's June 2026 brochure separates this from the G25 2.5-litre grades and from the sedan body. There is no external electric charging requirement for this petrol selection.
Both have current Australian manufacturer sales routes. Ask for the model year, build and compliance details, equipment and allocated vehicle on each proposal. A current national campaign does not establish that a particular colour or vehicle will be delivered when you need it. If delivery timing is essential, get that condition resolved before selling your existing car.

Two driveaway references, with different conditions
BYD advertises $28,888 promotional driveaway pricing for Dolphin Essential. The campaign requires a retail order between 15 September and 15 December 2026 and delivery by 31 December 2026. Metallic paint costs extra. Demonstrators and transactions involving additional promotional offers or discounts are excluded; the offer cannot simply be stacked with another promotion.
Mazda advertises Pure hatch and sedan from $32,990 driveaway. Its footnote includes 12 months registration, 12 months compulsory third-party insurance, stamp duty, other applicable statutory charges, dealer delivery and administration. Premium paint is excluded, personal circumstances can change the final amount, and the offer cannot be combined with another offer. This hatch comparison does not use a sedan's cargo capacity just because both bodies appear in the same price campaign.
Obtain written proposals for your postcode and paint, the same payment basis and only the accessories you actually want. Compulsory third-party insurance is not a substitute for a comprehensive insurance quote. Treat charging installation as a separate household cost unless the proposal expressly includes it.
If financing, compare a fresh complete proposal rather than substituting a monthly payment for the driveaway price. A novated-lease discount, fleet transaction or unrelated BYD cashback is not automatically part of the retail Essential campaign. No private finance eligibility or tax saving is assumed here.

The Dolphin is shorter, but load the same objects before choosing
BYD's brochure lists the Dolphin at 4,290mm long and 1,770mm wide. Mazda's hatch dimensions are 4,460mm long and 1,795mm wide excluding mirrors. On those body measurements, the Dolphin is 170mm shorter and 25mm narrower. That is useful context for a tight parking space, not a promise that either car fits with mirrors out and doors open.
The Dolphin publishes 345 litres of luggage capacity before folding and 1,310 litres with the rear seats folded. The Mazda3 hatch publishes 295 litres VDA; the sedan's 444-litre figure belongs to another body. We have not established a common measurement method between BYD's stated capacity and Mazda's VDA figure, so we do not promise an extra 50 litres of usable bags in the Dolphin.
Take the same pram, shopping boxes or work cases to both cars, keep the seats required by your passengers upright and try the opening and floor. Fit the child restraints you will use, then adjust the front seats for the usual drivers. Check how easily an adult can reach a buckle or lift a child in without leaving enough room only on paper.
If the Dolphin handles those tasks and is easier to park in your space, its compact body is a concrete advantage. If the Mazda's driving position, load access or seating works better for you, that can outweigh nominal litres. Neither an exterior dimension nor a review of a different grade decides the family test.

The Essential needs an electricity routine you will keep using
The Dolphin Essential's brochure range is 340km WLTP combined. That laboratory reference is not a promised distance for a loaded highway trip. Speed, weather, hills, air-conditioning, passengers and arrival reserve can change the distance between useful stops.
Before choosing, identify the repeat charging arrangement: the car's parking space, access hours, electrical supply, installation permission where relevant, and the tariff you will pay. If you rent or share parking, resolve the practical arrangement before depending on a future installation. An occasional public fast charger is not necessarily a convenient weekly substitute.
The model page's advertised 80kW fast-charging feature is marked Premium only. Do not use it to promise a charging stop for the Essential. Obtain the selected car's charging specification, supplied cable and session conditions, then check the stations on your actual longer routes. Count diversion, access and queues as well as time connected.
The Mazda needs petrol rather than a wallbox. For a driver whose destinations change at short notice, retaining that familiar refuelling process may be the deciding advantage. For a driver charging where the car is already parked, visiting a service station may be the extra task. Choose the inconvenience that genuinely disappears from your week.

Do not convert two laboratory figures into a household saving
Mazda publishes 5.9L/100km combined for the 2.0-litre automatic hatch, based on ADR81/02. Its sedan and 2.5-litre grades have different figures. This is a manufacturer test reference rather than fuel consumption measured on your commute.
The Dolphin's 340km WLTP reference is a distance claim, not the electricity billed to your house. Dividing battery capacity by advertised range would leave out charging losses and would not establish what a public charging session costs. The two figures cannot provide a fair fuel-cost comparison by themselves.
Use the annual distance you actually drive and the prices of the petrol or charging options you would really buy. Include installation if needed, insurance, servicing and the intended ownership period. We have no matched household driving data, insurance quotes or resale outcome that would justify a guaranteed annual saving or break-even date. The lower advertised Dolphin purchase reference does not make those unknown running costs disappear.
Keep Pure equipment separate from the optional Vision package
The G20 Pure page of Mazda's brochure lists an 8.8-inch display, USB Apple CarPlay and Android Auto, rear parking sensors, a reversing camera and a multi-function commander control. Its optional Vision Technology list separately includes a 360-degree monitor, a 10.25-inch screen and other functions. Do not assume that a base Pure at the advertised price includes that package or the heated seats and premium audio of higher grades.
The Dolphin Essential brochure lists a 12.8-inch rotating touchscreen and a 360-degree view monitor in its specification. The panoramic glass roof, wireless phone charging and other Premium convenience features must not be copied into the Essential just because the model page also shows them. Have the dealer demonstrate the functions you care about on the actual grade.
With both cars parked, connect your phone, set a destination, change temperature and try the camera view in the sort of space you normally use. Some drivers may prefer Mazda's commander arrangement; others may find the Dolphin's screen and all-round view useful. We have not measured which cabin or interface is better for your eyes, posture or habits. A larger screen or a camera does not remove the need to check the surroundings.
Check the support that accompanies the exact order
Ask both dealers for the applicable vehicle warranty, exclusions, servicing requirements and roadside-assistance conditions, plus the workshop that would handle an immobilised car. For the Dolphin, include the traction-battery terms and any capacity conditions. The warranty period is not a measurement of reliability, parts availability or repair speed.
Check safety equipment and the assessment applicable to the Australian version you are buying. Do not rank crash protection by the number of cameras or driver-assistance names. Demonstrate the warnings safely and understand their limits; no system replaces the driver's responsibility.
This shortlist has a more important first question than a brand-level ownership prediction: does the vehicle fit the household's energy and transport routine? We have no equivalent long-term reliability or total-cost sample for these two exact selections.
Which one I would buy for each routine
I would choose the Dolphin Essential when dependable charging is already available or properly arranged, its route planning is comfortable and the pram-and-passenger test works. Confirming eligibility for the $28,888 campaign and its delivery deadline would be part of that decision, rather than assuming the price from the headline.
I would choose the Mazda3 G20 Pure hatch when charging detours would become a regular burden or petrol refuelling better suits unpredictable travel, provided its seats, hatch opening and actual quotation work for the household. If both routines are easy, let the loading test, controls, insurance and complete quotes decide instead of awarding a winner from a battery range or fuel-consumption label.
Sources were consulted on 21 October 2026. This is documentary research with editorial judgements, not a CathayEV road or charging test. CarsGuide's Australian comparison shows a genuine local Mazda3/Dolphin alternative, but its 2024 tested grades and verdicts are not presented as a current G20 Pure versus Essential test. See other Australian buying comparisons if neither suits the way you use a hatchback.
Questions before the two test drives
- Is the Dolphin Essential price $28,888 for every purchase?
- It is a retail promotional driveaway reference, with orders from 15 September to 15 December 2026 and delivery by 31 December. Metallic paint costs extra, demonstrators and stacked promotions are excluded, and your actual car and eligibility need a written quote.
- Does the $32,990 Mazda offer include on-road charges?
- The manufacturer Pure hatch/sedan offer lists 12 months registration and CTP, stamp duty, other statutory charges, dealer delivery and administration. Premium paint is excluded and the final amount can vary with personal circumstances. It is not a comprehensive insurance quote.
- Does Essential have the 150kW motor and 427km WLTP range?
- No. Those model-page headline figures belong to Dolphin Premium. Essential has the 70kW motor and a 44.9kWh battery; its brochure combined WLTP reference is 340km. Do not substitute a figure from another test cycle.
- Does a base Mazda3 Pure include the 360-degree camera?
- The June 2026 brochure puts the 360-degree monitor in the optional Vision Technology package for Pure. The base grade lists a reversing camera and rear sensors. Ask for the exact package and price rather than treating the model-page demonstration as standard equipment.
- Which is better without home charging?
- Mazda3 is my first shortlist if depending on public charging would add regular detours or uncertainty. I would still consider Dolphin if dependable charging fits another place you already park. Resolve that arrangement and test the same passengers and luggage before buying.
