Proton Satria Neo
The Campro CPS engine is finally in the Proton Satria Neo, something that many have been eagerly waiting for. The CPS is essentially a Campro engine with a few updates and a variable valve lift system called CPS as well as a variable intake manifold (VIM) system. These additions help push up power to 125 PS at 6,500rpm and 150Nm of torque at 4,500rpm, figures which are up from the standard Campro’s 110hp and 148Nm.

The car’s front and rear track has also been updated. While the Proton Satria Neo had a front and rear track of 1,470mm for both, the Satria Neo CPS H-Line has a narrower front track at 1,467mm and a wider rear track 1,483mm.

We didn’t managed to get hold of a Proton engineer to ask this question but we did manage to ask a member of Proton’s Race Rally Research (R3) team who said the change was made because Proton found the standard Neo suffered from slight oversteer, so this change was made to induce a slight understeer to improve handling. Anyway either way as a result of the large wheel arches, the wheels looks kind of lost inside them at certain angles.

As for aesthetics, as you can see there’s a new bodykit and more prominent flared wheel arches that are inspired from the old Satria GTI’s design. The alloy wheels are of the same 16 inch size as the M-Line but feature a different design that looks like a carbon copy of Advanti Racing’s MEDUSA design but without the two-tone design - perhaps it’s licensed or “inspired”. On the interior, the dashboard is now of a darker shade with red lighting on the various air conditioning controls and auto gear position indicators, has a different door trim design, some new trim around the gear shifter area, and leather seats in a black and red combination similiar to the GEN2 CPS.

The following are the prices for the new Proton Satria Neo CPS, available in only two colours which are unique to the CPS - solid white and tranquility black.
CPS is only available for the high line model, so the lite and M-line models retain the regular Campro. Unfortunately this is the old original Campro engine, without the new IAFM systems in the Saga, Persona and GEN2. The CPS system has also been tweaked with this version of the Campro engine, so the high lift cam profile activation point has been revised. However I’m not sure what is the purpose of activating it later.

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. The CPS system uses a switching tappet and a trilobe camshaft to switch between two different cam profiles, one with low valve lift and another with high valve lift.
