Proton Waja Campro 1.6 Premium (CPS) Details
Click to enlarge
The latest revision to the Waja as scooped earlier this week is the new Proton Waja Campro 1.6 Premium (CPS) as it is officially called, and these are the official details.
Let’s have a look at the equipment level first before we get to the juicy CPS stuff. The Waja Campro 1.6 Premium (CPS) comes with either a 5-speed manual gearbox or a 4-speed auto. It has electrically foldable remote wing mirrors, front seats with three-way adjustable headrests (up, down and tilt), leather seats all around, a gated automatic shifter for the automatic transmission model, new center panel switches, a keyless trunk remote system, ABS brakes, dual SRS airbags, fog lamps, twin tailpipes and projector Xenon headlamps with automatic headlamp levelling.
Perhaps the most interesting update to this Premium CPS Waja is like its namesake, the Campro CPS engine. This engine has been eagerly awaited by many, as the current Campro has often been referred to the “Campro without Campro” – there was no cam profile switching involved. With the new S4PH Campro CPS, there is.

This is how the new Proton Campro CPS works. The CPS system integrated both cam profile switching (CPS) and a variable intake manifold (VIM). VIM switches between a long intake manifold at low RPMs and a short intake manifold at higher RPMs. According to Proton, a longer intake manifold is used at low RPMs to achieve slower air flow; this promotes better mixing with fuel. The short intake manifold allows more air in faster. This is beneficial at high RPMs. This seems to be slightly different compared to the usual VIM system where intake manifold width is also varied to control air velocity, and velocity tries to be maximised, but the idea behind the CPS VIM seems to be not wanting the air to go in as fast as possible at low revs to promote air-fuel mixture? Whatever it is, it seems to work, as the VIM does not stand alone but works with all the other engine systems together over different RPMs.
The CPS system uses a switching tappet and a trilobe camshaft to switch between two different cam profiles. One cam profile provides low valve lift, while the other cam profile has a high valve lift. The low valve lift cam profile is used at engine speeds of under 3,800rpm to maintain idling smoothness and ensure lower emissions, while the high lift cam profile is used when the engine is spinning more than 3,800rpm to improve peak horsepower and torque.
Using this two performance-improving systems, Campro CPS engine basically runs in three modes at any one time:
| Engine Speed | CPS | VIM |
| 0 to 3,800rpm | Low Lift | Long Runner |
| 3,800rpm to 4,800rpm | High Lift | Long Runner |
| Above 4,800rpm | High Lift | Short Runner |
The result is 125 horsepower (93kW) at 6,500rpm and 150Nm of torque at 4,500rpm compared to the non-CPS Campro’s 110 horsepower (82kW) at 6,000rpm and 148Nm of torque at 4,000rpm. Engine displacement is 1,597cc, bore and stroke is 76mm x 88mm and the compression ratio is 10.0:1. To handle the higher power and torque output, the Campro CPS engine has an additional oil cooler.

I drove the car earlier this week but did not really go very far, only got up to 2nd gear on the manual tranmission and did not even rev up to the redline – whatever short impression I had was quite good indeed. I am quite eager to test drive the new CPS-equipped Proton Waja and cannot wait to bring you my findings.
The new Proton Waja Campro 1.6 Premium (CPS) is priced at RM61,888 for the manual transmission version, while the one with the automatic transmission is priced at RM64,888. It comes in six colours: bronze garnet, blue agate, iridescent white, twilight blue, metal gray and burgundy. Standard warranty is 2 years, but it also comes with an Extended Warranty Program, extending total warranty to 5 years.
Let’s hope that after this we will be able to see a new Waja – the Saga was the first Proton and the Waja was the first non-Mitsubishi-based Proton. We don’t want to see a similiar product lifecycle with the Saga do we?

first comment!
no torque graph?
February 6, 2008 @ 6:55 pm
TEST DRIVE PLEASE! Would be nice to see how this fares in real-world driving. I drove a friend’s Waja and, sorry to say it sucked! The switches didn’t feel ergonomic at all, and the car felt like the trunk was full of bricks. This CPS thing has sure taken a LONG long time to get here.
February 6, 2008 @ 6:59 pm
simillary 3 stage tuned engine, bravo,
this engine if in satria neo really makes a sports car
February 6, 2008 @ 7:01 pm
Oh yeah and please don’t just put before/after torque curves of Waja Campro vs. Waja Campro CPS. Compare to some other manufacturers as well – Japanese, Korean, etc. How well does this CPS stack up to VVTi, CVVT?
February 6, 2008 @ 7:14 pm
exterior wise r very dull!
front grill should go!
still haven’t used up that dog-bone(crop-circle) taillight ka?
engine spec are delicious, but hope it is as reliable as Mitsu 4G’s engine! If not short life, gone kaput easily!
CPS + VIM are from Bosch kah ? or P1 develope ownself ?
Hope its from Bosch/others as their product are more reliable and their profile includes many renown makes in Auto industry!
February 6, 2008 @ 7:16 pm
Good news for Waja lover. for me better wait for a new waja.
February 6, 2008 @ 7:42 pm
Well, at least they sound like they’re going in the right direction..lolz.
February 6, 2008 @ 8:39 pm
So now Proton have performance to go with its handling. Good job. Next target, Reliability.
February 6, 2008 @ 9:17 pm
CPS similar to VTEC/MIVEC or VVTi? It sounds like having 2 camshaft profile instead of changing the camshaft timing.
February 6, 2008 @ 9:42 pm
VTEC proton, hahahaha
I assume this camshifting is only on the intake valves?
February 6, 2008 @ 10:09 pm
Ya, some changes on the out look of Waja will be great. Especially the front. Way out dated look already.
Congrats on the CPS engine, plus so many nice additional features. Sure this bring Proton one level higher.
Hope to see your test drive finding soon, Paul.

——————————————————
-yes it happened just on the intake,
-no variable timing, but its automatically advanced and delayed closing for overlapping when fast cam anggaged where its profile is wider and taller,
-its nor vvt i which vvti help the torque spread, not intelligent (i)
but VIM sort this problem at lower somehow its good as well,
-is vvt i batter at high end?
no, cam profiling is batter at high end because if the lift advantage,
February 6, 2008 @ 10:58 pm
Hmmm … I wonder if they used B16/B18 style squirter jets under each piston to squirt oil. I believe they used these on the Felda Rally Gen2. That had a four-throttle intake and the ECU was tuned by some ex Arrows F1 guy.
February 6, 2008 @ 10:59 pm
The graphs look good. Should be a very driveable car (=

February 6, 2008 @ 11:27 pm
Paul, from your review I gather that the CPS is only a two-step variable valve timing. Is it not CVVT or Continuously Variable Valve Timing? Kindly clarify.
Paul Tan says: it is variable valve lift, and NOT continuous
February 6, 2008 @ 11:35 pm
paul, can u tell us where did u get the bhp and torque comparison chart?? is it genuine from proton or just dynoed by 3rd party(yeah, if any)?
Paul Tan says: from Proton
February 7, 2008 @ 12:17 am
The VIM in Campro CPS not by Bosch.
February 7, 2008 @ 12:21 am
the first time i saw the new grill, i totally dislike it…but the more i see it, the more i began to appreciate it..i dont know why..but it kinda looked fresh to me..maybe it takes time to get used to it..same goes to the tail light design..it looked even more gorgeous during night time..first look from far away, i thought i was tailgating a beemer but it turned out to be a waja..hahah..kudos proton!!lets show those karimasin what were made of..
February 7, 2008 @ 12:54 am
I think proton need to sell this to breakeven the cost for developing new front hood and grill
February 7, 2008 @ 1:04 am
I have 1 question. What happens when you are climbing a steep hill where you use manual/auto at low gear speeds and rev the engine pass 5k rpm? The engine will become hotter, faster? It can happen. Imagine car full with people and stuff makes it heavier, need more torque from the car.
Paul Tan: our car’s radiator system is designed to kau tim this, as long the cooling system is in tip top condition should be fine. during testing phases engines are tested in simulated conditions such as the one you mentioned
February 7, 2008 @ 1:10 am
Paul, Campro CPS peak hp is at 6,500rpm not 6,000rpm you reported. Your torque chart look not right…although correct on the patterns, but it understates CamTakPro peak torque and exaggerates the improvement. Proton has its own official output chart at
http://www.proton.com/innovation/rnd/campro.php
Correct peak torque, CamTakPro is 148Nm @ 4,000rpm vs Campro CPS is 150Nm @ 4,500rpm. Campro CPS’s peak only better by 2Nm, achieved because 500rpm higher. Key improvement in Campro CPS is the smoothened torque curve for the 2,500-4,000rpm, where CamTakPro’s torque is some 10Nm weaker.
Paul Tan says: peak hp at 6,500rpm is correct. but as for the torque curve, i have two different copies of torque curves, one from Proton PR department and one from Proton Powertrain department. the one i’ve put here is from Proton PR as the Proton Powertrain one compares CPS with IAFM. its quite interesting really as it shows the torque curve of a 1.6 liter campro with IAFM, and this is an engine that we have not seen in the market yet. we have only seen a 1.3 liter with IAFM.
but i am not insisting either one is correct though. there are two ways to look at this: either proton has understated the old engine’s torque curve to make this one look better, or it could be that the campro without CPS’s torque curve has been overstated all these years and in that graph too.
but in any case if anyone wants to refer to the other curve you’re talking about, can just click on the link you provided.
best way to feel the improvement is in the drive.
February 7, 2008 @ 1:11 am
weird that articles like these do not mention the airbags in the features list???
so is there any airbags?
for the usual joes out there like me, i think we are curious how these torque curve is gonna help the car… it has more power but the main point is – does it consumes lesser? most ppl will wanna know that as the oil price hike is inevitable and their car purchase have to last for a few years to come… the current waja consumes too much compared against the japanese entry level cars…
p/s: if i would buy the car, the grill and the tail light has to go before i am seen driving with it by my friends… it sucks… but the headlamp has to stay… dun wanna touch the HID… hehe…
Paul Tan says: there are airbags. airbags have been made standard on the Waja, there is no model offered without airbags. in theory the engine will encourage a driving pattern that saves fuel as you do not need to rev very high to get decent progress
February 7, 2008 @ 1:33 am
i agree with the doubts of kingglim towards the torque curve…
the graph published by MTM on another website shows a more interesting comparison against the pre-campro waja and japanese 1.5 VVT technology…
but still the torque curve doesnt match each other very well but both claims the source is from Proton… not harm to Paul, but its confusing for ordinary people out there…
February 7, 2008 @ 2:09 am
icic….. paul, can u post the torque comparison between cps vim and cps iafm too??
btw, the starter sound also changed like new saga or still like prefacelift waja campro minus???
February 7, 2008 @ 2:14 am
Hmmm, I dont trust Proton much…their numbers are not good. Proton almost never shows accurate numbers…you check their cars’ specifications, you will notice that they almost never update the specs (especially 0-100, top speed and FC) despite all the updates, modifications and facelifts. For example, my 04 iswara LMST with big ah beng muffler got same 0-100, top speed and FC just like the old iswara, where can???.
This time, Proton seems like try to show different torque curves for different objectives…fishy. I suggest people to testdrive the car themselves…better trust your feel than Proton’s numbers.
February 7, 2008 @ 3:56 am
Seems to me that the CPS improves higher end peaked torque, thus increasing the hp tremendously.
Will the engine goes on fire again, like the 1st gen of Gen2 and recently, Satria Neo?
February 7, 2008 @ 5:58 am
a lot better than the std campro, but the power curve looks too linear, so no sudden burst of acceleration then

It will goes on fire ur head…
February 7, 2008 @ 11:25 am
Charger, u have to understand what cause the engine on fire 1st…satria neo’s case is due to carelessness of 1 of d cheras workshop that has chinese name vf around 20 branches there…go guess what’s d workshop name…its not due to the reliability of d engine.
after all, proton gona buy back her neo and replace it vf a new neo. lucky girl

cut and paste toyota corolla 1.6 vvti
February 7, 2008 @ 2:02 pm
ok vvti intelligently trying to gain torque at every range,
BUT it only manage to peak it at 4800 (4500 is 300rpm away),
power just 110 as opposed 127,
talking about torque ,batter for flat torque is 8 valve idsi,
BUT complaining car not as spritely as v-tech, cant go far,
why need high red line, who use it?
imagine the unexpected, you need a safe overtaking, you need this,
im not condemning other manufacturer but now campro cps engine ok,
February 7, 2008 @ 2:03 pm
conventional 4G92 engine provided 145 hp at 7000 rpm,the MIVEC-equipped engine could achieve 175 hp at 7500 rpm.(wikipedea)
the camTakPro is about 110bhp while the CPS is about 125bhp..
compare with those 2 engines, the BHP hike is almost the same-lah.(25-30bhp increase),thats good actually.
*supposely the new ’silently’ released Satria Neo R3 should be equip with CPS+VIM.(this car is beeeeeauty!)
February 7, 2008 @ 2:13 pm
why this 1.6 corolla only 81KW? Event the 1.5 Vios is 81KW.
February 7, 2008 @ 4:03 pm
and i found
a dual vvt from a corolla model, is 124hp at 6k,
which is not bad as a comparison since its ‘dual’
February 7, 2008 @ 4:24 pm
dual means intake n exhaust…usual vvti is for intake or exhaust? forgotten
February 7, 2008 @ 4:34 pm
vvt-i is just for intake valve…..
where dual is intake & exhaust valve
Campro CPS actually work similarly to honda city VTEC 1.5….it can be say they were almost the same, cz VTEC in City will only engage when you hit 3500rpm…
Honda i-vtec, is a dual cam profile system, work both in intake & exhaust valve…..the “i” is meant intelligent where it does the work of continuely…..
where is “si-fu”..? he shall be able to clarify more about the CPS…..in short, CamPro CPS = Honda VTEC (1.5 city)
February 7, 2008 @ 5:49 pm
all i would say,
campro cps principally equvalent a 2 stage v-tech with intake resonance system,
not dynamic control or intelligent cam phasing, nor dual vvti, nor A v-tech,nor valvetronic,valvematic, nor combination vvt+cam change,
February 7, 2008 @ 8:34 pm
paul , any idea if its still using the same springs and dampers as the std waja?? from the pics it looks like the CPS sits abit lower than the std waja…
February 7, 2008 @ 9:37 pm
this is what im waiting 4 , muahahaha !!!
February 8, 2008 @ 12:23 am
maknyer, u need to improve ur maths. 175-145 = 30bhp while 125-110 = 15bhp is almost 50% difference leh… not almost same…
February 8, 2008 @ 12:39 am
Anyway where is the Gen.2 CPS? huh, Thailand get first and now gone?
February 8, 2008 @ 2:38 am
i think proton should use the campro with cps+vim in it h-line model and campro with IAFM for its other models…the old campro engine should not be produced anymore..
1 question…any idea whether those driving waja campro,gen2,satria neo and persona using the old campro engine, can upgrade their engine to cps+vim campro or IAFM campro?? like plug the system into the engine or some sort like tat??
February 8, 2008 @ 10:10 am
The engine performance seem to be good but whether it is reliable that’s another question. The exterior design of Waja is just boring I think I will consider buying it if after the engine is tested but consumer at least 3 years and this but into New Saga or Persona. Anywhere it’s good sign Proton is improving. Pls continue so that my son in 10years time will get cheaper and better car.
February 8, 2008 @ 10:14 am
the exterior really need a make over, butt great news bout the engine, hope they’ll make a 1.8l version ang pu it into a Satria neo GTi or sumthing..that would be great!!!
on a side note, I’d stumble a P1 basher,who not only deletes every comment thats pro P1, he also insults n curses everyone

February 8, 2008 @ 10:32 am
LittleFire85, oo man! i mess up with my calculators,sory!
i went to proton showroom to see the new WAJA CPS, the seats are better than the 1st waja model. the gated gear shifters are quite tricky to use, but looks nice actually.
hopefully new proton models will have a smoother signals&wipers stalks like the myvi’s.
February 8, 2008 @ 10:35 am
I think this will be difficult, coz if u want to plug in u need to change the whole engine head for the CPS + VIM. The IAFM maybe easier a bit but still the ECU mapping may need to remap again…
New stuff are not cheap man…Even last time i heard a new Waja auto Gearbox from Proton almost cost a bomb (RM10k if i not mistaken)… If proton really did this, how the old engine goes if they trade in ur old wif new? Sell it to China? Or scrap it for nothing? I think for Proton ppl, they will just ask u to change for new car for more benefits.
February 8, 2008 @ 11:21 am
cool…
come on buy one… hehe
February 8, 2008 @ 6:42 pm
I think the silver Perdana behind the 1st picture is Paul’s perdana hehe…
February 8, 2008 @ 10:12 pm
Gee, didn’t I ask for the performance curves a few days ago? This is scary. Somebody actually listens. Thank you. Neo CPS it is then!
I don’t think people (still) understand why there (still) is a Waja and a Gen 2/Persona. They are catered for a different market segment/demographic. The Waja appeals to the above 35, family oriented (and therefore has more income) market. If you wanted something more spirited its the Gen 2 or Neo. If you look at the whole product range, Proton caters to a wide market segment.
I would thought that the Waja would sell better in China because it is the least Japanese looking. It has its original intention for the Euro market and therefore would be good in China. At least Shanghai. I guess if Eurostar does it right, the Waja would be on the next boat.
February 9, 2008 @ 2:05 am
Besides the oil cooler are there any mods to the engine? Oil squirter jets as on B-Series Honda engines?
February 9, 2008 @ 1:41 pm
wait for hotbits to make an exhaust system and adjustable cam pulleys..u wil easily get 135hp !
bt as someone said above…although the looks abit disjointed at the front…its starting to grow on me…if u see it in flesh it kinda looks nice and attractive in a weird way !

Er, anyone know about Waja Corporate?
Informed by someone that it’s only RM48,000!
Is is tue, Paul? Can you check the diff?
February 10, 2008 @ 8:49 pm
erm.. why there is no improvement on exterior design ?
February 10, 2008 @ 11:25 pm
Waja Corporate?……
what is the different?
February 11, 2008 @ 1:14 am
well…
at least they tried to make this Waja better..
i think…
February 11, 2008 @ 1:50 am
thanx for the info paul…waiting for your test drive…this new waja cps features is not great but not bad either i would say…the exterior look i think can be acceptable in 2@3 more years(i like those xenon head lamps looks)..the interior facelift is cool…nice looking and felt expensive…the most important is the CPS engine..hope what the graph show is the same with the reality…i hope this CPS+ VIM wil eliminate the torque drop problem from the prev campro version…btw…at first i thought gen2 cps will be launch first…mayb its for marketing purpose since persona still sell like hot cake so give it room to up the number some more before go with the high performance gen2 cps…i like the new sportier look of the new gen2…plus with high performance engine on the hood the new gen2 wil rox…so sad if the quality is still the same like prev gen2..hope its not. that what i think
February 11, 2008 @ 3:04 am
don’t interested in the engine just like to say ‘ugly grill, ugly rear lights, overall an ugly car…
February 11, 2008 @ 7:49 am
Kudos to the chaps at Proton, I like what they have done with the package of the car. Giving out auto-levelling Xenon lights, leather seats, gated shifter etc. really does make it an improvement. I guess the term “Premium” can be applied across the Proton line-up. However, still again, I think its a classic case of “too little, too late”. The looks still leaves much to be desired.
Paul, with Proton and their efforts lately to introduce the CPS and VIM, is there any news of Proton going into the “semi-automatic” tranny areas? Not sure if there was any news on this…. thanks a bunch!
February 11, 2008 @ 8:56 am
Engine sudah tukar..good.Now change it to whole new car la. Waja already 8 years old..Proton..please do the Waja FMC this year..
February 11, 2008 @ 9:49 am
every body love proton..
February 11, 2008 @ 8:09 pm
WAJA is a nice n good car but IMHO i really dislike its power window button…
February 19, 2008 @ 9:32 pm
WAJA CPS OUT NOW
So, When is Gen.2 and Satria Neo’s turn ?
February 21, 2008 @ 9:34 pm
Paul, all those fires that happen to these Campro engined cars, are they normal ? I mean, can this happen to any car or is the Campro engine lacking something that makes it catch fire more easily ?
March 4, 2008 @ 8:40 am
Leonardlee, its not normal not only for campro engine but also other type of engine if it catch on fire. Simple as that. Not only campro , new camry, even merc with 1/2 million prized also catch on fire. It depend on your luck…or suwei…ho..ho
March 14, 2008 @ 5:45 pm
Maybe its just me…but it looks uglier after the facelift………sorry I like the original WAJA better…….
