More 3-cylinder turbocharged Proton models coming – 1.5T MPI to be rolled out further

The next generation of Proton models will use three-cylinder turbocharged 1.5-litre port injection (MPI, multi-point injection) engines, says Proton.

Speaking at a press conference at today’s Proton X50 preview drive at the Sepang International Circuit, Proton’s Director of Group Engineering En. Hazrin Fazail Haroon told the assembled media that the new 1.5T MPI will feature prominently in Proton’s future powertrain line-up.

Hazrin didn’t specify which model will use the 1.5T MPI next, but among the models speculated to be coming next are the Geely Jiaji, which will sit above the Proton Exora, and at least one more SUV model.

The Proton Saga is also due for a replacement, and it will most likely use the same B-segment Modular Architecture (BMA) platform that currently underpins the Proton X50.

Both the Proton Iriz and Proton Persona are also due for a specs update. Both models’ CVT-type transmission are rumoured to be replaced by 4-speed automatic, but we are not sure if the 1.6-litre naturally aspirated Campro engine will be replaced as well.

The 1.5T MPI engine is currently used in lower range variants of the Proton X50, making 150 PS/226 Nm. The highest specifications X50 Flagship will use a more powerful 177 PS/255 Nm direct injection 1.5 TGDI engine.

The 1.5T MPI engine is a new development by Geely (and Volvo), and it’s making its world debut in Malaysia, in the Proton X50 (lower range variants).

Despite making significantly less power than the TGDI engine, the MPI engine actually consumes more fuel than the TGDI engine. Claim fuel consumption is 6.5-litre/100 km, versus the TGDI engine’s 6.4-litre/100 km.

It is however, cheaper to produce than the TGDI. Being a port injection unit, it’s also less susceptible to carbon deposit build-up in the intake valves.
