With most of Proton’s models already updated with the company’s latest powertrain, all that’s left is the Proton X90, which is expected to receive its first mid-cycle update in the very near future.
The Proton X90 was first introduced in Malaysia in May 2023, is currently the only Proton model yet to adopt the Geely-sourced BHE15-EFZ 1.5 litre turbocharged 4-cylinder engine that has already made its way into the refreshed X50, X70, and S70.
Given that Proton has progressively rolled out the updated engine across the rest of its line-up, it is only a matter of time that the updated X90 – widely referred to as the X90 MC1 – will complete that transition.
If the update mirrors the mechanical changes seen in the latest X50, X70, and S70 revisions, the i-GT 1.5 litre turbocharged and direct-injected 4-cylinder engine in the X90 MC1 will produce 181 PS at 5,500 rpm and 290 Nm of torque between 2,000 and 3,500 rpm.
Proton has previously stated that the switch to the BHE15-EFZ engine delivers a notable reduction in noise, vibration and harshness (NVH). The engine uses a toothed timing chain rather than a timing belt, eliminating the need for periodic replacement while offering a service life rated at over 200,000 km.
However, unlike the pre-updated X90, which employs a 48-volt mild hybrid system paired with the 3-cylinder engine, the updated model is unlikely to retain hybridisation. While the outgoing setup produced higher peak outputs of 190 PS and 300 Nm, removing the belt-driven starter-generator simplifies the powertrain and should reduce long-term maintenance costs.
Efficiency gains from the newer engine, together with recalibration of the seven-speed dual-clutch transmission, are expected to offset the loss of mild hybrid assistance.

Early test vehicles spotted on local roads suggest that the X90 facelift will remain visually similar to the current model. The test units appear to retain the same exterior design, including the standard 18-inch alloy wheels seen on lower variants. Interior changes are also expected to be modest, potentially limited to new trim finishes or colour combinations.
The most significant cabin upgrade could be the addition of wireless Apple CarPlay and Android Auto. These smartphone connectivity features were originally promised for the X90 but never implemented on the production model.
They are likely to arrive alongside an updated infotainment system running a newer version of Proton’s Atlas operating system, similar to what is found in the latest X50 and S70.

Currently, the Proton X90 is offered in four variants:
- Standard – RM 123,800
- Executive – RM 130,800
- Premium – RM 144,800
- Flagship – RM 152,800
As seen with the recent X70 update, Proton may simplify the X90 line-up when the facelift arrives, potentially reducing the number of variants.
