Charging and range
The rated figures side by side: electric range and fuel use with the battery depleted for a plug-in hybrid or range extender, the km each battery-electric car adds overnight on its own onboard charger, and the DC time in the window each document prints.

Feature Showdown
The BYD Dolphin features a 12.8-inch touchscreen paired with a 5-inch digital dash, while the Mazda CX-70 gets a 12.3-inch display and 12.3-inch instruments. Apple CarPlay and Android Auto are standard across both.
The BYD Dolphin stands out with Apple CarPlay and V2L: features our data doesn't list for the Mazda CX-70. The Mazda CX-70 counters with wireless Apple CarPlay/Android Auto, head-up display, wireless charging, panoramic roof, heated front seats, power tailgate and Bose audio. Which feature set matters more depends on your daily routine and priorities.
Interior trim differs: the BYD Dolphin gets synthetic leather upholstery while the Mazda CX-70 offers leather.
Equipment few rivals have, on either carShowHide
Drivetrain
The BYD Dolphin uses a Electric producing 70kW and 180Nm of torque, sent through a auto to a FWD layout. It covers the 0-100km/h sprint in 12.3 seconds.
The Mazda CX-70 responds with a Diesel making 187kW and 550Nm, paired to a automatic driving all four wheels. It gets to 100km/h in 8.3 seconds.
The Mazda CX-70 has the clear power advantage at 187kW vs 70kW. In the 0-100 sprint (manufacturer-claimed), the Mazda CX-70 is 4.0s quicker. For most buyers, the way each car feels day-to-day matters more than outright acceleration.
Space & Comfort
The BYD Dolphin measures 4,290mm long on a 2,700mm wheelbase, 830mm shorter than the Mazda CX-70 at 5,120mm (3,120mm wheelbase). The longer wheelbase on the Mazda CX-70 generally means more rear legroom.
Boot space is 345L in the BYD Dolphin and 598L in the Mazda CX-70, giving the Mazda CX-70 a 253L advantage.
Neither U-turns in one sweep on a 7 m local street (both need a three-point turn); the BYD Dolphin's turning circle is 1.4 m tighter, 10.4 m against 11.8 m kerb to kerb. The street estimate is indicative, worked from the published turning circles.

How to read this page. Prices, specifications, ANCAP ratings, warranty, the CarSorted Score and the verdict come from our records for the grades shown, sourced from the manufacturers' Australian documents, and change when those records change; the date each was last checked is printed under the headline. Prices are recommended retail prices before on-road costs unless marked drive-away. A plug-in hybrid's fuel figure is labelled with its basis: with a full battery (the certified combined figure) or as a hybrid (battery depleted). Charging and running costs are estimates on the stated assumptions. Always confirm price and specification with the manufacturer or dealer before you buy. CarSorted does not accept payment for recommendations.
