Waja Campro vs. Waja 4G18

The Proton S4PH Campro is an inline 4 cylinder 16 valve Double Overhead Camshaft engine. Performance stats are 110hp at 6000rpm and 148Nm of torque at 4000rpm. One look at the stats would give you a slight idea of the torque curve for this engine. With the peak torque coming in at a relatively high RPM, this engine is meant to be a high revver for spirited driving. Gen2 owners have mentioned the torque actually rises, then dips a little at the 3000-4000rpm range before going up again to the maximum 148Nm of torque at 4000rpm.

On the other end of the ring, we have the 4G18. The Mitsubishi 4G18 is an inline 4 cylinder 16 valve Single Overhead Camshaft engine. It makes 102 horsepower at 6000rpm and 140Nm of torque at 2750rpm. Big amounts of torque at low revs is a typical characteristic (not all the time though) of SOHC engines, making it a nice and stressless drive in city driving situations.

Unless Proton retunes the Campro to readjust the torque curve for more torque at lower RPMs, I think the Waja Campro is going to be a sluggish drive as you’d have to rev pretty high all the time to get decent acceleration. Even Gen2 owners are complaining, and the Waja is a 1205kg car, abit heavier than the Gen2’s 1190kg.

Proton Waja

The Proton Waja is the first passenger car designed in-house by Malaysian automotive company, Proton. The sedan model was launched on August 2000 powered by a Mitsubishi 4G18 1.6 L engine, and starting from 2006 by Proton's own 1.6 L Campro engine. During the end of 2005, another variant of the Waja with a longer wheelbase and powered by a Mitsubishi 6A12 2.0 L V6 engine known as Proton Waja Chancellor was launched.

The name Waja, which means "tough (as steel)", reflects the strength of the steel used for the Waja compared with the previous models. The name was chosen partly to counter the perception in the domestic market that Proton cars were less strong. In the United Kingdom, the Waja is sold as Proton Impian.

History
The Proton Waja is the first model designed in-house by Proton. The development of the Waja began at the end of the 1990's together with the Campro engine, however the development of the Campro engine was still in progress at the time of its launch and therefore Proton had to source the 4G18 engine for the Waja from Mitsubishi. The model was launched in August 2000 together with the introduction of Proton's new corporate logo.

The early batches of Waja production might have had some interior quality problems due to some component vendors and suppliers skipping quality checks to rush for the huge early demand, however the quality of the components were strictly improved in later years.

In 2002, the 1.8 L variant was introduced, powered by the same engine used in Renault Laguna II. The 1.8 L model incorporates drive-by-wire technology and variable valve timing technology. However, the 1.8 L model suffered poor sales because Malaysian customers were more familiar with Japanese engines and less confident of European engines especially on the availability of spare parts, therefore the 1.8 L variant was phased out in the next year.

At the end of 2005, Proton introduced another variant of the Waja known as Proton Waja Chancellor, used by representatives of Asean nations during the meeting of Asean leaders in KLCC shortly before the launch. The Waja Chancellor has a longer wheelbase and is powered by a 2.0 L V6 engine similar to that used in Proton Perdana V6, also sourced from Mitsubishi.

It was not until January 2006 that the Campro engine was finally used to power the Waja. Even though the engine is similar to the engine used in the Proton Gen-2, the Campro engine used in the Waja has higher horsepower and torque, probably due to the remapping of the ECU and also the different air intake system.
