Having experienced the Proton S70 MC1 firsthand, I can attest to the impressive performance uplift that the new 1.5L i-GT turbocharged engine offers compared to the earlier 3-cylinder setup. The car feels notably more responsive, especially during city driving and overtaking maneuvers on highways. One highlight is how the torque output of 290 Nm provides smooth acceleration and better mid-range power delivery, which enhances overall driving confidence. The 4-cylinder turbo engine’s refinement also helps reduce engine noise and vibration, making longer drives more comfortable. Besides performance, the handling improvements make the Proton S70 MC1 more agile and stable around corners, contributing to a more engaging driving experience. The engineering collaboration between Proton and Geely clearly shows in the upgraded ride and handling dynamics which feel well-tuned for everyday use as well as spirited driving. For Proton enthusiasts or potential buyers in Malaysia, this 2026 update offers excellent value, combining modern turbocharged power with practical ride quality. If you’re coming from the 2023 model or considering a mid-size SUV, the MC1’s enhancements justify giving it a test drive to truly appreciate the refined performance and driving comfort it now delivers.
