Proton S70
2023–present · 1.5T TGDi (3-cylinder, Geely-derived, direct injection) · 7-speed wet DCT
The Proton S70 (2023+) is Proton's first proper sedan since the Wira era, based on the Geely Emgrand/Binrui platform. The 1.5T 3-cylinder TGDi with 7-speed wet DCT shares its core with the X50. Direct injection means carbon buildup at 60,000–80,000 km. DCT fluid every 40,000 km is critical. Practical sedan for value-conscious buyers.

Proton S70 Common Problems Malaysia
Proton S70 (2023+): DCT shudder on the 7-speed wet DCT — same family as X50 DCT. DCT fluid every 40,000 km is critical. Carbon buildup from 1.5T 3-cylinder direct injection at 60,000–80,000 km. 3-cylinder vibration at idle is characteristic, not a fault. Software update history important — early units may need Proton SC calibration update. First Proton sedan in years: parts sourcing developing.
