Dimana2 RWD vs FWD itu emang endless discussion :D

Kalo gw sih,

FWD lebih enak manuver (but not traction) di jalan es/salju : Yes (walaupun cuman bisa ngebayangin)
FWD Lebih efisien tenaga/lebih hemat BBM : Yes

Selain itu No.

Bro, kalau mau coba manuver di es/salju ... bawa saja FWD yang kecil... (Picanto, Jazz) ke Mal Taman Anggrek / Tempat Ice Skating atau ke ICE WORLD di ANCOL....
Kalau ke SNOW WASH bisa gak ya ?????? hhhhehheeee....

Boleh juga tuh... SERAYA MOTOR mensponsori... perlombaan mainan AWD atau Remote Control (yang 4x4) di Track Ice Skating / ICE world... rasanya belum ada deh... seru juga khan....

tambahan,
konon RWD lebih nyaman/halus driving-nya, baik buat driver or passengernya, kalo FWD cenderung terasa sentakannya/terasa lebih kasar.

Setahu saya ada teknologi yang namanya balancer.. gunanya untuk menghilangkan getaran pada setir di mobil-2 FWD.

IMO rwd cars lebih fun untuk di pakai daripada awd/fwd cars karena lebih terasa responsenya banyak yg suka bilang rwd cars lebih sulit dikendalikan daripada fwd/awd cars kalau jalan sedang licin tapi dengan teknologi spt DSC(beemer talk for stability control) rwd cars juga menjadi gampang di kendalikan. AWD/fwd cars mempunyai keunggulan atas mobil rwd di daerah yg ada musim salju tapi ini dengan catatan mobil awd/fwd dilengkapi dengan proper winter tire tanpa ini awd/fwd tidak ada bedanya dengan rwd.

Kalau di race track dengan stabiltiy control cr@p off gw lebih prefer rwd daripada awd(with few exception) kalo fwd stock/tanpa modifkasi sih gw nggak prefer untuk di track karena understeer issue apalagi dgn mobil mobil yg weight distributionnya lebih berat di depan(nose heavy). FWD cars menurut gw lebih "susah diatur" buat cornering di track karena waktu mau approach corner apex stock fwd cars sudah mulai ada gejala understeer yg memang gampang di koreksi dengan mengurangi throttle tapi ini sudah membuat kehilangan waktu dan keadaan ini juga sama waktu mau keluar dari corner jadi lebih banyak buang waktu untuk koreksi understeernya. Lain dgn rwd car yg bisa menggunakan sedikit throttle steer untuk mengatur arah mobil on the way out of the corner dengan hampir full speed. Untuk awd feeling gw 50/50 karena gw berasa mobilnya nggak natural terutama waktu di mid corner tapi dengan awd gw bisa bejek throttle abiss on the way out dan mobil tetep terkendali tanpa harus khawatir dgn oversteer. AWD experience gw cuma terbatas dengan sistem TORSEN di audi b4 s4 yg kalau nggak salah awd biasnya masih 60/40 yg berarti lebih mendekati karakteristik fwd cars lain dengan high end awd cars seperti awdnya porsche(spt 996/997 turbo) yg awd biasnya 20/80(CMIIW).

Pengalaman gw ini berdasarkan:
fwd: 00 audi TT fwd
awd: 01/02 b4 s4
rwd: 04 e46 m3/06 e60 520(non track)/07 e90 320(non track)

Tergantung track, utk track-rally (selain awd class), better FWD drpd RWD.
AWD lebih cocok untuk mobil power (juga torque) raksasa , seperti EVO & GTR di track general/umum.
Ini sangat membantu kedinamisan mobil pada range kecepatan middle to low (Katakan range 160km/h ke bawah), atau terutama saat akselerasi.
Karena pada range ini sangat mungkin (salah satu/lebih) roda spin saat akselerasi (kehilangan traksi krn kelebihan tenaga).
Untuk meminimalkan ini, disini tenaga raksasa perlu disalurkan efisien ke setiap titik roda yg paling diperlukan.
Mobil yg dikendarai khusus pada most range kecepatan sangat tinggi lebih baik RWD.

Intervensi elektronis spt DSC, dll; pd mobil everyday car memungkinkan pengendalian yg lebih mudah utk user, namun belum tentu menghasilkan kecepatan/laptime terbaik di lintasan balap; krn intervensi ini juga untuk kepentingan user-friendly & safety pengemudi awam.
Yg lebih advanced pengaturan biasnya ada di ATESSA-ETS skyline, introduced 1989 R32, di-refine sampai yg 2008 R36.
Juga di EVO, ada 3 mode kalo tidak salah tarmac / gravel / road.

Yg interesting, ada FWD kencang melahap tikungan :
Stock U.K Civic typeR-R 8th-gen = everyday (& race-track juga) FWD 260hp (hampir setara NSX pertama, RWD 270hp) yg bisa kencang di lintasan, lahir di sirkuit balap, namun FWD ini masih bisa juga mencapai objectivenya (& memang dari dulu diakui) : fun-to-drive.
Jaman dulu, stock Prelude FWD dgn ATTS (active torque transfer system, lawannya LSD), dan ada yg SH-AWD.

Saya nggak pengalaman ama mobil canggih2. Tapi dulu pernah 1.5 tahun kuli di perkebunan sekitar 4 ribu HA. Di area kebun tsb, kadang ada ruas jalan yg konstruksi nya "aneh". Walaupun hujan lebat, tanah nya keras tapi kadang tertutup 2-5 cm ama humus/tanah bawaan air. Karena bawah nya keras, mirip jalan di lantai semen tapi dilapisi lumpur.

Di kondisi jalan seperti itu kira2 beda FWD ama RWD :

- FWD jalan relatif lurus/terkendali. Tapi bukan berarti traksi nya lebih bagus. Tidak ada kondisi yg bisa dilewati FWD, tapi tidak bisa dilewati RWD. Yg ada malah sebaliknya. RWD bisa lewat, FWD kepater.

- RWD jalan nya cenderung lenggak-lenggok dijalan lurus, atau malah jalan lurus dibelokan alias nggak mau belok. Walaupun nggak pernah belajar ngedrif dan nggak niat ngedrif, tapi dijamin sekali2 mobil akan mutar 180 derajat tanpa sengaja. Nggak pernah terjadi kalo FWD.

-FWD lebih mudah kepater daripada RWD. Sekali FWD kejeblos, sulit bisa lepas. Kalo RWD, kalo masih sempat ngerem, masih ada kemungkinan bisa selamat/mundur. Asalkan roda belakang, belom ikut masuk.

To be honest, yg saya bandingkan itu sedan dengan minibus. Tapi saya yakin, valid jg untuk sesama minibus or SUV.

masalahnya bobot sedan sama minibus beda.. jadi susah di bandingin..

menurut gw..
buat mobil body kecil.. cc kecil fwd ok , selain lebih ekonomis / hemat, dan hadnling bagus buat mobil tenaga kecil..

Rwd buat mobil body berat, tenaga besar lebih enak controlnya, traction nya lebih enak karena bobot kalo akselerasi cenderung ke belakang.. huat high powered car enak rwd...

AWD master of all season.., jeleqnya pasti mahal, bobot lebi berat, dan bensin jau lebih boros..

Nimbrung juga ah!

Cmiiw tapi semua pembahasan di atas berasumsi posisi mesin di depan (front engined) yang artinya FWD lebih efisien dan irit, RWD lebih rumit dan ada hilang tenaga dsb dsb.

Tapi overall, sensasi mengemudi RWD rasanya lebih unggul daripada FWD. Jadi mungkin yang paling ideal itu RWD dengan posisi mesin di belakang (rear engined). Kalau konfigurasi begini, mesin di belakang and roda penggerak di belakang, efisiensinya sama dengan mobil FWD bermesin di depan. Tapi punya keunggulan karakteristik handling mobil RWD.

Dua mobil legendaris dgn konfig begini : Porsche 911 dan VW Beetle original (VW Kodok). Yang baru malah FWD dan mesin di depan, gak beda dengan Honda Jazz

Walau kalah populer oleh konfig FWD/front engined apalagi di Indo yang disesaki mobil Jepang, tapi sekarang lagi bangkit kembali tuh. Contohnya, Smart (tau kan?) dan the real new VW Beetle : VW concept UP yang bbrp taun lagi akan diproduksi massal

Ini khan mobil yang berjalan tidak pakai mesin tapi kemana-mana bawa mesin cadangan di bagasi.... hhehhehehheee....

wah udh hampir 7 thn nih trit sunyi, ane coba ah lanjutin... copas dari http://www.carsdirect.com/car-buying/fr ... heel-drive


Front Wheel Drive vs. Rear Wheel Drive

Today we find that vehicles come in 3 drive configurations front-wheel drive, rear-wheel drive and 4 or all-wheel drive. In this article, we will focus on only front and rear-wheel drive. Front-wheel drive is where the engine drives only the front wheels. Rear-wheel drive is when the engine drives only the rear wheels.

Front-wheel drive is used in order to provide a compact package. Very little space is necessary since the engine and the wheels being driven are in the front of the vehicle. A center tunnel or a higher chassis is not necessary as they would be in a rear-wheel-drive configuration. The driveshaft of the rear-wheel-drive vehicle has to reach from the engine to the rear wheels causing the need for a tunnel or higher chassis. The front-wheel-drive-configuration also promotes good traction.

Due to their better traction due to weight distribution, front-wheel-drive vehicles are preferred to rear-wheel-drive if one needs to drive in snow, mud or wet roads. However, front-wheel-drive vehicles are not always as quick to accelerate as rear-wheel drive because of weight transference that takes place during acceleration causes the front wheels to sharply reduce their grip and this adversely affects torque.

Find the New Car that’s Right for You >>

In addition, front-wheel-drive vehicles feature a transverse engine (facing side to side) while rear-wheel-drive vehicles have a longitudinal engine (facing front to back). Due to the style of the engine, front-wheel drive actually restricts the size of the engine. That is why you will see front-wheel-drive cars with inline 4 and V6 engines. Longer engines such as Inline 6 and big bore V8 engines have a difficult time fitting into the available space. This is why most luxury cars as well as sports cars more often than not have a rear wheel drive configuration.

Advantages to a Front-Wheel-Drive Configuration Include:

More Interior Space
Lower Weight
Less Cost to Manufacture
Improved Drivetrain Efficiency
Forward Center of Gravity Which Improves Traction
Predictable Handling

Disadvantages to a Front-Wheel-Drive Vehicle Are:

Poorer Torque Allowing Front-Wheel-Drive Vehicles to Pull Left or Right when They Are Accelerated with Some Force
Lack of Weight Shifting Which Limits the Acceleration of the Vehicle
Reduced Traction When the Vehicle Is Climbing a Slope in Slippery Conditions
The CV Joints Attached to the Wheel Hub Tend to Wear Out Faster
Increased Turning Circle Because the Transverse Engine Limits the Amount the Front Wheels Can Turn
The Size of the Engine Is Restricted

Advantages to a Rear-Wheel-Drive Vehicle Include:

Even Weight Distribution
Better Weight Transfer During Acceleration
Better Steering Radius
Better handling On Dry Roads
Better Braking
Better Towing Capability
Easier Serviceability
Can Feature More Powerful Engines

Disadvantages Include:

Possibility of Oversteering When the Vehicle Is Accelerated Hard
Poorer Traction In Snow, Ice and Sand
Less Interior Space
Increased Weight
Higher Cost for the Vehicle
Improper Weight Distribution When the Vehicle Is Loaded
A Longer Driveshaft to Reach the Rear Wheels

So, as you can see, it is important to consider your driving habits and needs to determine which configuration would be right for you.

Jadi mana yg lbh baik antara FWD & RWD? klo menurut tulisan disini, tergantung dari masing2 habit & peruntukan mobilnya, dan yg penting semua jg tergantung keandalan supirnya.... :big_exellent:

sekedar crita dari sirkuit Sentul hari minggu kmaren, pas acara "track day" yg terbuka utk umum : dari 6 atau 7 mobil yg melintir masuk gravel, hanya 1 yg FWD yaitu Pug 406. Yg laennya adalah mobil RWD (beberapa Biem e36, dan 1 Merc AMG dan 1 Merc E300 yg nabrak tembok di tikungan S besar)

Btw, setelah hampir 7 thn berlalu, tentunya sudah banyak teknologi baru yang diterapkan.

Mobil FWD sekarang juga canggih2, konon dulu salah satu kelemahan mobil FWD ini di handling torsinya. Kalau sudah diatas 250-300Nm, dulu kalau buat FWD jadi serasa sia2, apalagi torque steering-nya

Tapi dengan perkembangan teknologi, mobil FWD sekarang juga sudah bisa handling torsi besar.

Salah satu pionir-nya, Ford Focus RS, dengan spek 2500cc 300HP/440Nm
Jaman dulu, kalau ada mobil hatchback dengan output 350HP/440Nm dengan layout FF (FWD), bakalan banyak yang ngga percaya dan diketawain

Ford Focus RS dengan teknologi revoknuckle suspension dan LSD quaife, mampu menjawab tantangan itu :frm_salut:

salah satu yg menarik TG s21 kemarin golf vs bmw M135i..................

Golf yg FWD handling bisa jauh lebih baik dari M135i saat cornering uda g understeer lagi.. malah oversteer... dengan defisit power yg beda jauh, lap time bisa hanya beda tipis...

FWD hothatch lain seperti fiesta n focus ST handlingny bnyk dpt pujian presisi dan minim understeer... salah satu fitur kunci handlingnya y itu torque vectoring elektronik di front diff..........

meski gw tergelitik juga... dri so called "car show" itu golf tidak bisa di matikan ESP/TCS nya 100% which is kunci handlingnya.. sedangkan BMW dimatikan 100% a.k.a "mode drifting"........... ntah apa yang terjadi jika di BMW juga tidak dimatikan ESP/TCS nya





cuma tetep... jika saya ada rejeki beli hot hatch/sport car untuk mainan... ga mikir pasti ambil RWD...................

Buat pengemudi harian/awam, menurut saya sudah tentu FWD

FWD = Safe
RWD = Fun
Fun tidak selalu safe

FWD cenderung understeering, kalau sudah kejadian begini, kontrol dan counter relatif lebih mudah. Kurangi gas, injak rem gradual dan arahkan setir (teorinya sih)
RWD cenderung oversteering, kalau sudah kejadian apalagi jalan licin, butuh skill yang lebih untuk kontrol dan counter. Di jalan licin, sering resiko fishtailing alias buritan megal-megol, apalagi kalau ban belakang sudah hilang traksi

sebenernya RWD tampa LSD.............. minim atw err sulit terjadi oversteer di sengaja aja sulit...

sedangkan FWD 78ps AT aja uda bisa kerasa terjadi understeer.

Betul pak,

Yang jadi point-nya, kalau sama2 kejadian baik understeer maupun oversteer, secara teori (pengemudi awam), kontrol dan counter understeer relatif lebih mudah dibanding oversteer
