When buyers last but not least acquired the facelift Saga and experienced the 4AT, it acquired a combined bag of evaluations. Some claimed which the new transmission built the Proton sedan far better, while some called it a step back when it comes to engineering.
Mod ECO juga boleh memisahkan sistem klac untuk membolehkan kereta meluncur tetapi ini cuma untuk halaju bawah 70kmj. Bagaimanapun, tindak balas luncur itu akan tamat (klac kembali aktif) apabila menekan pedal brek atau minyak.
Ini dibuktikan dengan penurunan kadar aduan daripada pelanggan berkenaan dengan CVT sebanyak eighty% berbanding sebelum design MC1 diperkenalkan.
Sistem klac ini akan bersambung balik sebaik sahaja pedal minyak atau brek ditekan. Jadi pada pandangan penulis, apabila klac diputuskan enjin akan kekal beroperasi pada julat RPM terbaik untuk menurunkan penggunaan petrol (finest BSFC). Menurut En. Adzrai, ECO Manner berupaya menjimatkan petrol sehingga one%
With Proton acquiring officially unveiled facelifts for that Iriz and Persona hatchback and sedan designs originally of final thirty day period, the B-phase duo continues being enhanced, most apparently in its infotainment, seems and devices. Much less was pointed out with regard to the vehicles’ mechanical elements, and the amount of has actually been performed to boost them. Some is going to be wanting to know – why has Proton retained the Punch continually variable transmission? Proton automobile programme executive Adzrai Aziz Ibrahim available explanations in detail via a virtual briefing. Proton arrived at the choice to stay with the Punch CVT gearbox soon after getting done a good amount of study together with considering market responses, reported Adzrai, in particular benchmarking Japanese B-section cars and trucks for this purpose. The CVT would be the transmission that gives the most beneficial gasoline use for the worth and phase; this is actually adopted by most brand names within the segment, he included. When the newest Iriz and Persona facelifts had been rumoured prior to start to generate the swap into a Hyundai four-pace torque converter automatic transmission, this wasn't selected for that not too long ago-released automobiles as 4 ahead ratios had been considered insufficient and for that reason would be detrimental to gas intake. This is of better great importance to cars such as the Iriz and Persona, in lieu of outright Value, and In combination with The point that the B-phase duo sells in significantly scaled-down figures in comparison to the Hyundai 4AT-Outfitted Saga – Proton’s greatest-seller – of which four,500 to five,000 units are sold each month, for that reason the cost of engineering the fitment of a completely new gearbox to your Iriz and Persona could not be justified.
A lot has been stated regarding the Proton Iriz‘s CVT – the overall consensus through the push generate event was that though the new auto shown gains in many spots, the Punch-sourced gearbox, by comparison, has essentially the most room for enhancement. Keep in mind, the gearbox in question – an improved ‘CVT2+’ unit about the CVT2 found in the Saga FLX – is without having question Proton’s finest-undertaking Up to now. There has been continual improvement – the Iriz’s gearbox betters the Suprima S‘ device, which subsequently bettered the Preve‘s, which bettered the Exora‘s. Still, when it comes to linearity, response and refinement, it still falls short to some degree of other CVTs on the market. Proton is mindful of this Achilles’ heel, and In line with chief technological officer Abdul Rashid Musa, it is “finding out the possibility” of switching to your CVT that makes use of a torque converter (like the CVT artikel menarik Utilized in the Honda Town/Jazz) as an alternative to a start-up clutch, to enhance pulling clear of rest, along with gas use.
With a traditional torque converter, the transfer of ability is instant just like in a traditional computerized transmission. That may be why Proton goes for Jatco CVT for its forthcoming model to handle this problem. Jatco materials CVT for both equally mitsubishi and Nissan

The Punch CVT gearbox has an exceedingly small bell housing size, a torque converter primarily based gearbox won't be as quick. The driveshafts may must be of somewhat distinctive size if the ultimate drive differential Proportions are a bit diverse in comparison to that with the compact Punch CVT.
Fungsi S juga telah diperkenalkan pada CVT yang digunakan oleh Persona/Iriz. Menurut En. Adzrai apabila pemandu memasukkan tombol equipment pada kedudukan S, CVT akan beroperasi pada ratio yang lebih rendah dan memaksa enjin untuk berputar sehingga 200-300 RPM lebih tinggi berbanding dalam kedudukan D bagi menghasilkan tork yang lebih baik.
It lags as it employs a commence clutch to transfer electrical power as opposed to The existing gen CVT which makes use of a torque converter. It was a difficulty within the 2nd gen Honda Town CVT which has an identical set up.
Menurut En. Adzrai Aziz lagi, antara calon yang sesuai untuk menggantikan transmisi CVT ialah transmisi 6 kelajuan automatik namun dihadkan dengan kekangan kos dan masa pembangunan.
Oleh kerana Saga FLX tidak diberikan pilihan S, maka untuk memecut dan memotong kereta lain pedal minyak perlu ditekan secara beransur-ansur bagi mendapatkan pecutan sekata serta perancangan rapi.
For that reason, Proton has employed the stepped transmission method for use all through challenging acceleration. With all the prolific work which has long gone into bettering and refining the transmission during the 2022 Iriz and Persona, why was this not publicised in marketing materials with the cars and trucks’ launch? Because it turns out, Proton has made a decision that attention was very best targeted upon the more obvious new characteristics like the new GKUI with its voice command features, and also to advertise the advent from the Iriz Active as a new variant.
