This week, the Malaysian automotive scene is abuzzed with news that the Proton Saga FL would be equipped with a CVT gearbox. Why CVT (Continuously Variable Transmission)? For starters, CVT gearboxes has less transmission loss if compared to the conventional auto box. Therefore, Proton sees it as a good opportunity to replace the more-than-10-year-old Mitsubishi F4A41 gearbox. Also, CVT gear shifts are seamless, as it uses virtual ratios to adjust itself. That also brings a smoother drive to the driver and also delivering better fuel consumption. The CVT gearbox will also be used on Proton new Exora turbo.

So now, the question is, who’s CVT gearbox is Proton testing with? It could be a few, but chances are either Punch Powertrain or Nissan’s. Just for your information, the CVT gearbox used in the Mitsubishi Lancer (and also the Proton Inspira CVT) is from Jatco. Jatco used to be a subsidiary of Nissan. So considering the fact that Proton has recently signed a MOU (Memorandum of Understanding) with Nissan, it would be no surprise that the CVT ‘box would be indirectly from Nissan.

Therefore, there is a 50-50 chance that Proton’s CVT gearbox is either from Punch Powertrain or from Jatco of Nissan. Till then, we can only wait for more spyshots and inside news. Also, we found an interesting video on the drivetrain company, Punch Powertrain. It is an European company but gearboxes are manufactured at China.
