Verdict
The BYD Seal 6 is the cheaper, cleaner commuter at RM100,000, with a 410 km EV range, 100 kW DC charging and stronger listed driver-assist kit. It is also the sedan with the bigger quoted boot, 460 litres against the Proton X90’s 257 litres. The X90 answers with the thing the BYD cannot do: seven seats. Its RM106,800 price buys a larger D-segment SUV body, a 1.5 litre turbo petrol engine with 178 hp and 290 Nm, and the practicality of a third row.
Pick the BYD Seal 6 if you want a five-seat electric sedan with 410 km range, lower road tax and more listed driver-assist hardware.
Pick the Proton X90 if you need seven seats, SUV height and petrol refuelling rather than EV charging.
