Because the Proton S70 approaches its official launch date, the brand new sedan has been revealed to make use of a turbocharged engine that’s the 1.5 litre, port-injected three-cylinder petrol unit that’s supplied within the non-FLagship variants of the Proton X50 B-segment SUV.

Given its engine specs that may give it a bonus over its rivals that may compete with the S70 on worth, it begs the query: why not specify the extra highly effective, 177 PS/255 Nm direct-injection 1.5 TGDi engine as used within the X50 Flagship and X70, as an alternative?

Based mostly on Proton’s calculations, the carmaker has discovered that the 1.5 litre port-injected turbocharged engine “is appropriate for the S70,” stated Proton deputy CEO Roslan Abdullah.

“Once we developed this automotive, we’ve got targets to fulfill, when it comes to gasoline consumption, efficiency, and dealing with. Going by these targets, we’ve got realised that the [port-injected] 1.5T is adequate in assembly our targets for this car. That’s why we [have chosen] the 1.5T, and another choices [would be] a plus for us sooner or later,” Roslan stated.

This might imply that whereas Proton deems the 1.5T engine adequate for the S70, a door may very well be open for the S70 to obtain a unique engine specification sooner or later.

Conversely on the extra inexpensive finish of the S70 worth spectrum, paultan.org requested if there had been any consideration for a less expensive engine – may Proton have used the naturally aspirated 1.5 litre unit just like the one used within the Geely Emgrand, which may deliver its beginning worth to RM60k, particularly since Proton has even greater gross sales quantity targets of late?

“At this time, if we [use] a 1.5 NA (naturally aspirated) engine, there’s a concern when it comes to its suitability for the C-segment, when it comes to the car’s weight. In Malaysia, our roads have many inclines [uphills]. We consider that the 1.5T engine, together with the seven-speed dual-clutch computerized transmission will present a greater driving expertise,” Roslan responded.

“When it comes to [local] manufacturing, there’s the 1.5T and the 1.5[TGDI]. To make use of the 1.5 NA engine, that’s to say, with out turbocharging, the specification of the engine [prepared for turbocharging]. If we don’t [offer the turbocharged engine], the aftermarket will supply turbos. As a substitute of giving freely the [turbo segment] enterprise, it’s higher we sapu (sort out the market) first,” he added.
