Proton S70 R&D car spotted testing – new update with 1.5L i-GT four-cylinder turbo engine coming soon?

A trade-plated Proton S70 has been spotted on the Klang-Banting Highway by Khairul Adelee Mangadi, who shared the photo on the paultan.org Automotive/Car Discussion Facebook Group. Is Proton testing an S70 equipped with the new 1.5 litre i-GT four-cylinder turbo engine from the X50 facelift?

This new BHE15TD (‘TD’ for turbo-direct injection, not turbodiesel) engine is widely expected to eventually go to the S70, X70 and X90, while the upcoming Saga MC3 will get a non-turbo port-injected BHE15PFI version of the engine.

The S70 is currently powered by a 150 PS/226 Nm 1.5 litre GEP3 port-injected three-cylinder turbo engine (left). The new direct-injected i-GT engine in the X50 facelift (right) develops 181 PS and 290 Nm of torque, so if it isn’t down-tuned in any way for the S70, that’s a considerable 31 PS/64 Nm jump.

Can we expect the updated S70 to launch this year? Engine aside, which of the X50 facelift’s many new features would you like to see in this sleek sedan?

    this is one of the advantage of collaboration with Geely. engine and chasis updates more frequent and able to tap on Geely’s volume in china to keep cost manageable.
    but proton main supply chain still needs to upgrade and keep up with geely standard and pursue to be part of geely worldwide supply chain to be competitive

      but but bashers like the comment above says that more frequent updates = low resale value. so according to them its better to keep on selling the same stale model for 10 years.

  • 181PS & 290NM for S70 should be nice. Now can be called ‘C’ Segment.
