BYD ATTO 3 vs MG S5

They look close but are quoted on different bases. In late 2026 the ATTO 3 opens at $39,990 before on-road costs for the carryover Essential, with the EVO Dynamic at $41,990 and the EVO Premium at $46,990, all before on-roads. The MG S5 is $41,990 drive-away for the Essence 49 and $46,990 for the Essence 62. Add on-road costs to the BYD and the two land within a few hundred dollars of each other, so neither is meaningfully cheaper. The better value question is what each fits as standard, where the MG's base grade is the more generously equipped.

Range is a BYD win, stated grade by grade. The ATTO 3 EVO Premium claims 510km on the WLTP cycle, clear of the longest-range MG, the Essence 62, at 450km. The EVO Dynamic sits at 420km, and even the carryover Essential's 345km just edges the base MG Essence 49's 335km. Real-world range depends on speed, load and climate, and both brands quote the same WLTP test, so the comparison is fair. If maximum range is the priority, the ATTO 3 is the stronger pick, and the Premium is the one to have.

This is the most grade-sensitive answer on the page. The ATTO 3 EVO Premium moves to an 800-volt architecture and accepts up to 220kW on DC, well beyond the MG Essence 62's 150kW, and BYD quotes a 25-minute 10 to 80 per cent charge. But the entry ATTO 3 Essential peaks at just 70kW, slower than the base MG Essence 49's 120kW, and the EVO Dynamic sits at 110kW. So if you buy the flagship BYD you get the quickest charging here, and if you buy the cheapest one you get the slowest. On home AC the cars are close, at 6.6kW for the MG and 7 to 11kW across the ATTO 3 range.

Both carry a five-star ANCAP rating, but the MG's is the newer and slightly stronger card. The S5 was tested in 2025 and scores 82 per cent for vulnerable road users to the ATTO 3's 69, and 86 per cent for child occupants to 84. Both fit seven airbags, including a front-centre airbag. The ATTO 3 edges it back on adult occupant protection, 91 per cent to 90, and safety assist, 80 to 79, but its rating comes from a 2022 test of the original car, and ANCAP has not yet tested the EVO update. Both fit the full active-safety suite as standard. On the record the MG is a shade safer, and its result is the more recent.

This is the S5's strongest card. It uses the rear-wheel-drive platform of the acclaimed MG 4 hatch, and Australian reviewers consistently praise its balanced handling and crisp steering, rare in an affordable electric SUV. The ATTO 3 is the opposite brief: comfortable and simple to drive around town, but reviewers agree it is not the engaging car the EVO badge suggests, with light steering and a ride that can feel floaty at higher speeds. The MG's trade is a firm low-speed ride and a base motor that is tame off the line. The ATTO 3 EVO Premium is the quicker car in a straight line, but for driver involvement the S5 is the clear pick.

The MG S5 makes the stronger ownership case. Its headline is a 10-year, 250,000km warranty when serviced through an MG dealer, against the ATTO 3's six years and 150,000km, and MG caps each service at $300 for roughly $1,500 across five years on 2026 pricing. BYD answers on two fronts: its battery warranty runs eight years and 160,000km to MG's seven, and the base ATTO 3 is the more efficient car at 148Wh/km to the MG's 169, so it uses a little less energy per kilometre. Service intervals are similar, 20,000km for the BYD and 25,000km for the MG, both yearly. For long-term peace of mind the MG's vehicle cover leads.

The MG S5 packs more into its entry price. From the base Essence 49 it fits heated front seats and a heated steering wheel, a panoramic sunroof, wireless phone charging, keyless entry, built-in navigation and digital radio as standard. On the ATTO 3, that comfort kit largely arrives with the EVO Dynamic rather than the carryover Essential. The BYD answers with the bigger central touchscreen, 15.6 inches to the MG's 12.8, while the MG runs the larger 10.25-inch driver display. Both include a 360-degree camera, wireless Apple CarPlay and Android Auto, and keep some physical controls. For standard kit per dollar at the base grade, the MG edges it.

It comes down to what you weight. If you want the sweeter drive, the fresher five-star safety result, the longest warranty and the more generous base grade, the MG S5 is the pick for most buyers, and its value is strongest on the Essence 49. If you lead with range, efficiency and charging speed, the BYD ATTO 3 is the stronger choice, and the 800-volt EVO Premium is the one that pulls clear with 510km and 220kW DC charging. Both are five-star-safe electric SUVs from the same price bracket, so neither is a wrong answer. Weigh the drive and the ownership package against range and charging, and your pick follows.
