Earlier this month, Proton held a preview session for the Proton S70, and we can finally share more details on the upcoming C-segment sedan. We can now confirm that all variants of the S70 are powered by the same 1.5L MPI turbo engine as the non-Flagship X50, and its Advanced Driver Assistance System (ADAS) is touted by Proton to be class-leading as well.

Let’s start with the S70’s 1.5L turbo engine first. Producing 150PS and 226Nm of torque, the mill is paired to a seven-speed dual-clutch transmission. Chances are, this is the same transmission used in the X50 and X70. But based on our brief time testing the car, the driving characteristics of the S70 feel quite different.

As for the ADAS of the S70, it is said to be similar to the X90’s, albeit with the omission of Auto Park Assist (APA) and Emergency Lane Keep Assist (ELKA). That being said, this is still a very sophisticated ADAS, especially for a C-segment sedan. Not only does it have 12 different sensors, it also supports Intelligent Cruise Control, Lane Centering Control, Lane Change Assist, and even Traffic Sign Information.

However, it’s worth noting that only the top two models of the S70 – Flagship and Flagship X, with the latter adding on a sunroof – are equipped with ADAS. You don’t get these active safety features with the base Executive or mid-tier Premium models. Nonetheless, at least the inclusion of six airbags is standard across the range.

Bookings for the Proton S70 are now open at all Proton 3S and 4S outlets, with public previews happening from 11 November onwards. Chances are, the previews will be reserved for customers who have placed a booking for the sedan. Production has started for the S70, so it is very likely the sedan will be launched sometime this month, just as promised.
