After many months of anticipation, the Proton S70 – previously referred to as the S50 – is finally official. However, Proton is still keeping the full specifications of the C-segment sedan under wraps, but based on a new leak, we believe all variants of the S70 will be powered by a 1.5L MPI turbo engine found in the X50 lineup.

As per a report by Funtasticko, which has received screenshots from a source showing the four different variants (Executive, Premium, Flagship, Flagship X) of the S70, all of them carry the 1.5T designation. It’s worth noting that this naming convention is used by the X50 as well to signify the models that feature the 1.5L MPI turbo engine.

With that in mind, we believe the S70 lineup will be powered by the sole 1.5L MPI turbo mill; assuming the screenshot shared here is legitimate, of course. Anyway, the turbo engine outputs 150PS and 226Nm of torque, and Proton confirmed that the sedan will be packed with a dual-clutch transmission. This is likely the same 7DCT used by the X50 and X70.

Bookings for the Proton S70 are now open at all Proton outlets, with public previews happening from 11 November. 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.
