The CFE, to be seen in the High-Line version, comes with a low-pressure turbocharger that delivers 138 hp at 5,000 rpm and 205 Nm between 2,000 – 4,000 rpm. The engine is mated to a seven-speed CVT Punch gearbox, the VT3, dubbed the ProTronic.

Figures include a 0-100 km/h time of 9.6 seconds and a maximum top speed of 200 km/h. As for fuel consumption, the CFE gets 8.2 litres per 100km. In all, the numbers that the 1.6 litre CFE generates is said to be similar to that of a 2.0 litre N/A engine.

As for the IAFM+, the mill equips the two M-Line versions of the car, one with the five-speed Getrag manual and the other, a six-speed CVT, in this case the VT2. A thing to note here: the engine and gearbox is the same as seen in the Saga FLX SE, but retuned for the Prevé (no output figures were given at the preview, but it should be the 108 hp as seen on the FLX). Even the accelerator pedal is tweaked to make the best out of the powertrain and drivetrain.

A quick aside on why there are two variations of the Punch CVT box. Essentially, the VT3 transmission is a derivative of the VT2 – both share the same package, but the VT3 is capable of higher maximum input torques (215 Nm as opposed to the VT2‘s 186 Nm).

Currently, the IAFM+ engine is tuned for Euro 4 emissions, and the CFE with CVT is good for Euro 5 emissions. Now, you may think that the Malaysian government has not enforced emission regulations, so why bother. Call it future-proofing, although everyone else has arrived earlier. Already, Thailand is on the verge of starting its eco-car program that gives all sorts of tax breaks to cars that have low fuel consumption and low CO2 emissions. Proton is looking at penetrating the Thai market, hence the readiness of more efficient offerings.

Utk model Exec with IAFM , performance keta mungkin lebih perlahan dari persona.

Bayangkan jika persona kerb weight hanya 1225kg tp P321A non-CFE 1325kg. Lebih 100kg+ beza. Cuma different 2Nm OFF TORQUE BETWEEN 2 ENGINES itu pun utk high end torque, low end torque hampir serupa.

Sng citer ia seperti membawa keta Waja CPS tp dgn additional 90kg load . Tapi prestasi enjin yg sama CPS=125hp/150Nm dan iafm+=107hp/150Nm. Which one is better?
Nape sy highlight utk model standard shj (sbb ini range most Malaysian probably afford to buy). So nanti kalo ade org complaint P3 ni underpower padahal enjin x sama tp model serupa sape yg kena…

xpe.. insya Allah power cukup. Lgpun CVT die berbeza drpd CVT Saga FLX SE 1.6. dari segi torque curve pun IAFM+ lbh baik berbanding IAFM Persona. Klau nk pickup lg, amek manual.

CamPro IAFM engine
A Campro 1.3L IAFM mounted on a second generation Proton Saga.

The CamPro IAFM (Intake Air-Fuel Module) is essentially a basic DOHC CamPro engine equipped with a variable-length intake manifold, developed under a joint fast track programme that began in April 2005 by EPMB, Bosch and Proton. However, the IAFM differs from the VIM (Variable Inlet Manifold) for the CamPro CPS engine in terms as follows:

The IAFM is a stand-alone module that can be fitted with a basic DOHC CamPro engine whereas the VIM needs to work in conjunction with the CPS system in a CamPro CPS engine.
The IAFM is operated by the engine vacuum, while the VIM uses an ECU-controlled solenoid.

The Intake Air-Fuel Module for the Proton's CamPro engine debuted in the second-generation Proton Saga, which was launched on 18 January 2008. It was first made known to the public in October 2006, when it was still in its advanced tooling stages.

With the IAFM, the 1.3L engine used in the Proton Saga now produces 98 bhp (73 kW) @ 6,500rpm.[6] The maximum torque is slightly reduced to 113.2 N·m (83.5 ft·lbf); however, the engine has broader torque range and the noticeable torque dip in the basic DOHC CamPro engine has been eliminated.[6] The official brochure is only published with the familiar 94 bhp (70 kW; 95 PS) at 6,000 rpm power and 120 N·m (89 lb·ft) at 4,000 rpm torque for consistency with other 1.3-litre Proton models.

Meanwhile, the output of the 1.6-litre version of the IAFM engine which debuted in the 2008 Proton Gen-2 M-Line produces 110 bhp (82 kW) @ 6,500 rpm of power and 148 N·m (109 ft·lbf) of torque, and the torque dip around 2,500-3,500 rpm has been eliminated.

The second-generation Campro IAFM engine, known as IAFM+ engine, was debuted in the 2011 Proton Saga FLX.[7] The new IAFM+ engine is tweaked to be paired with the new CVT gearbox by Punch Powertrain that requires the maximum operating engine speed to be reduced from the previous 6,500 rpm in the first-generation IAFM engine to only 6,000 rpm.[8] As a result, the 1.3L IAFM+ engine produces 94 bhp (70 kW) @ 5,750 rpm of horsepower and 120 N·m (89 ft·lbf) of torque, while the 1.6L engine produces 108 bhp (81 kW) @ 5,750 rpm of horsepower and 150 N·m (110 ft·lbf) of torque.[9][10] The combination of the new Campro IAFM+ engine with the CVT gearbox results 4% and 10% reduction on fuel consumption for urban and highway driving respectively.[7]
