| BYD Shark 6 Premium | Mitsubishi Triton GLS 4x4 | |
|---|---|---|
| Price | $57,900+ on-roads | $60,140+ on-roads |
| Type | Plug-in hybrid (petrol) | Diesel |
| Electric range | 100 km claimed | None |
| Fuel use | about 7.9 L/100 km once the battery is flat | 7.7 L/100 km (diesel) |
| Running cost per week (NSW) | $30.56 | $53.26 |
| Servicing per year | $552 | $400 |
| Tyres per year | $364 | $364 |
| Warranty | 6 yrs / 150,000 km (battery 8 yrs) | 10 yrs / 200,000 km (serviced by Mitsubishi) |
| 5-year cost to own | $74,425 | $81,809 |
Cost to own = price (plus about $4,000 on-road costs where the price is before on-roads) + a home wallbox for EVs (about $2,000, one-off) + charging or fuel + scheduled servicing + tyres. It leaves out insurance, registration and resale value, which vary too much by person and car to estimate fairly. Resale value is the biggest unknown, especially for newer brands.

How we work it out
Weekly cost is the car's claimed energy use (kWh per 100 km) × your distance × your electricity price. "Per week" figures on this site assume 250 km a week with 90% of charging at home. Petrol comparisons use the fuel use and price you choose. Prices are list prices at October 2026 and change often; check with the dealer.
- Electricity: 2026–27 default or regulated flat rates from the AER Default Market Offer (NSW, SE QLD, SA), Victorian Default Offer, Aurora Energy (TAS), Jacana Energy (NT), Synergy (WA) and ActewAGL (ACT).
- Public charging: Sydney survey of Chargefox, Evie, NRMA, Tesla and BP Pulse prices, July 2026.
- Car specs and prices: manufacturer figures as published by CarExpert, AEVA EV fact sheets, Drive and EV Central's car guide. Some prices are the publisher's estimates; check with a dealer.
- Servicing: published capped-price schedules (BYD Sealion 7, BYD Seal, Geely EX5, Jaecoo J5 EV, Kia EV5, Zeekr 7X). Tesla has no fixed service schedule and CarExpert's EV servicing comparison. Where a model's pricing isn't published yet we use the brand's nearest model and mark it as an estimate.
- Tyres: RACV puts EV tyre life at 20,000–40,000 km; replacement set prices from Gridly's 2026 EV tyre cost guide.
- Petrol and diesel: ACCC average retail unleaded and diesel prices in each capital city, 21 October 2026 (ACCC weekly fuel price monitoring).
- Plug-in hybrids: prices, battery sizes and claimed electric range from CarExpert, Cars24, Zecar and The Beep. Real-world electric range is taken as 80% of the claim; plug-ins charged at home each night are assumed to do up to 85% of driving on electricity. Petrol use with a flat battery is our estimate from reviews where makers don't publish one.
- Diesel utes and SUVs: claimed combined fuel use and prices from CarExpert, 4X4 Australia and CarSauce. The HiLux automatic, Prado and Mazda CX-60 D50e are 48-volt mild-hybrid diesels; their small battery assists the engine but can't drive the car on its own.
- Petrol mild hybrids (Suzuki Swift Hybrid, Mazda CX-60 G40e): claimed fuel use and prices from CarExpert.
- Hybrids: claimed fuel use, prices and capped-price servicing as published by CarExpert and CarsGuide. Petrol and hybrid tyres usually last 40,000–60,000 km (RACV); we use 50,000 km.
- Home chargers: typically $1,000–$3,000 installed, about $2,000 typical (What's the Damage, October 2026).
