Verdict
The Aion ES is the longer-wheelbase electric choice, with a 55.2 kWh battery, 442 km claimed range and 136 hp/225 Nm motor. Its RM106,800 price is RM47,000 above the Proton S70’s RM59,800, though annual road tax is RM20 lower at RM70. The S70 answers with a 500-litre boot, against 450 litres, and six airbags plus blind-spot monitoring. For a buyer with dependable charging, the Aion’s eight-year/160,000 km warranty and EV running format justify scrutiny; for outright purchase cost and luggage space, the Proton is far easier to defend.
The ES EV (RM106,800) sits above every S70 variant here, so the verdict compares the closest-priced pairing — use the selectors above to match any two trims.
Pick the Aion ES if you can charge regularly and want 442 km EV range, a 2,750 mm wheelbase and an eight-year/160,000 km warranty.
Pick the Proton S70 if RM59,800, a 500-litre boot and its six-airbag safety package matter more than electric driving.

ES vs S70 FAQ
Is the Aion ES or Proton S70 better?
The Aion ES is better for regular home or workplace charging, 442 km claimed EV range and longer warranty cover. The Proton S70 is the better budget-led choice: it costs RM47,000 less, carries 50 litres of luggage more and has six airbags.
What is the price difference?
The Aion ES costs RM106,800 and the Proton S70 costs RM59,800, so the Aion carries a RM47,000 premium. Its annual road tax is RM70, versus RM90 for the Proton.
Which has the bigger boot?
The Proton S70 has the bigger boot at 500 litres. The Aion ES provides 450 litres, leaving the Proton with a 50-litre advantage for luggage.
How long does charging take?
The ES's 55.2 kWh battery takes about 8.4 hours for a full AC charge, and an estimated 65 minutes from 10% to 80% on a DC fast charger at its 60 kW peak.
Which one is locally assembled?
The S70 is assembled in Malaysia (CKD), while the ES is fully imported (CBU) from China. Local assembly generally helps pricing and spare-parts supply, and CKD programmes usually signal a longer-term commitment to the model here.
