The current Proton S70 offers adequate power but still has room for improvement

The new Proton S70 retains its original space advantage despite core upgrades

The detailed optimizations of the Proton S70 better align with market demands

【PCauto】The core highlight of the new Proton S70 lies in the upgrade of its powertrain, featuring a 1.5L i-GT four-cylinder turbocharged engine, officially replacing the three-cylinder engine in the current model. This adjustment has become the biggest selling point of the updated S70.

Under normal circumstances, the engine of the current S70 is sufficient for everyday use. However, consumers have higher expectations and preferences for the operational smoothness of a four-cylinder engine.

And in practical use, it is noticeable that the three-cylinder engine has room for improvement in terms of power delivery smoothness, especially during high-speed cruising or long-distance travel with a full load.

The new S70 is equipped with an all-new 1.5L four-cylinder turbocharged engine, delivering a maximum power of 181 PS and peak torque of 290 Nm, which is a noticeable improvement compared to the current three-cylinder engine's 150 PS and 226 Nm.

More importantly, the four-cylinder structure itself can optimize the performance of power output, making the throttle feel more linear. It won't have a sudden jolting sensation in daily driving, and it provides stronger acceleration on the highway. The overall power performance is also more mature and stable.

Moreover, while the new S70 has completed its core power upgrades, it has not lost its advantage in space, continuing the practical design philosophy the model has always adhered to.

• Body proportions of this vehicle strike a balance between practicality and harmony.
• Rear legroom is very spacious, and even when fully seated, it won't feel too cramped.
• Slight bulge of the central floor does not make passengers uncomfortable.
• Trunk's volume is also impressive, meeting the needs for daily storage or packing for long trips.

Compared with sports-oriented models in the same price range, the new S70 still has a clear advantage in space practicality.

The new S70 will likely continue Proton's recent pace of optimization in software integration and localized tuning.

Based on the brand's past improvement logic and market feedback, the new model is expected to further enhance the reaction speed and interface logic of the vehicle infotainment system, addressing issues like occasional lag in the current model.

What we need to know is that all the changes are made to better align with the operating habits of local drivers. These detail optimizations are also a direct response to market feedback.

The power adjustment of the new S70 reflects the trend of car manufacturers optimizing product configurations to meet market demands. Although three-cylinder engines have certain technical advantages, actual consumer experience and market preferences remain the key factors determining a product's market performance.

Proton did not adopt flashy configuration stacking this time but focused on upgrading the quality of power，a core pain point. This not only enhances the overall completeness of the vehicle but also better aligns with the expectations of the mainstream market.

The new S70 is about to be launched. Whether this upgraded model can stand out in the fiercely competitive C-segment market is worth observing through its order performance in the market.
