With this in mind, starting in 1997, Proton began preparing to equip itself by strengthening its Research and Development (R&D) capabilities. Currently, thanks to rigorous research and development, it is a full-fledged automotive manufacturer capable of designing and producing its own car platforms, bodies and engines. However, at a time when most car manufacturers are rapidly moving towards hybrid engines, Proton had just made its first combustion engine and there was always going to be a snag in the technology Proton used compared to previous engine technology , or Mitsubishi, up to the current Campro. engine, built in-house with Lotus touch. For example, many Gen2 owners complained that the cars had dragging acceleration. This puts Proton in a situation that frames the lack of updated technology to bring the car to a satisfactory level of pickup. With the weight of the Waja Campro (1,205kg) and also the latest Exora (1,422kg), heavier than the Gen2 (1,190kg), this problem is more pertinent and causes slow driving as the driver has to rev at quite high revs all time to get a decent level.
