Tulak Or Batak?


Recommended Posts

mayroon kaya niticeable nuances between the 2?

 

Oh yes, quite. But only in the cars on the lower end of the price scale. Most fwd cars will tend to understeer (will want to continue going straight even after you have started to turn the wheel) when you power into a turn. I don't like the idea of having only two tires do all the work, i.e., propel the car while steering it, or stop a car while steering it. Your tires have a finite amount of friction/traction if you brake, you give up some traction for steering, if you accelerate the same thing happens. This is why you have torque steer in the cheaper fwd cars. If you gas it while on a curve, you will feel the wheel wanting to straighten up.

 

Unfotunately there are no rwd cheap cars anymore. The ones I could remember to be notable were the Mark I, Ford Escort Mexico with the 1.6 liter cast iron Kent engine fitted wwith twi Weber 40 DCOEs and the 1976 Mitsu Lancer they like to call the "L" type. RWDs tend to over steer under power in a corner. That is, the rear wheel can break traction and swing into the direction you are going and if you know what you are doing, you can actually steer the car with the accelerator pedal.

 

With all the electronic driver aids in the more upmarket cars, all of these disappear and create a car that is stupid-proof almost.

 

I still prefer all wheel drive. Now that is driving. Dependng on how you drive you can go from understeer to full oversteer and have a lot of fun in between.

May difference pala? :blink: Bakit hindi ko yata nararamdaman? Guys, care to explain further in layman's term? :unsure:

 

And is it true na mas magastos sa gasolina pag naka-4WD ka? Car ko kse lagi lang naka-set sa 2WD kse sabi nga mas magastos daw pag nilagay ko sa 4WD?

 

Ano muna car mo? some cars kasi di ni rerecommend na naka 4wd all the time. yun yung mga part time 4 wheel drive with a standard differential such as old vitaras and pajeros. 4wd drive lang kung slippery or needs more traction such as sand, rocks, snow( na wala naman dito).

kung equipped naman with lsd or limited slip differential puwede 4wd even on smooth hard surfaces like asphalt or concrete tarmac, mas may wear nga lang sa tires and of course mas malakas sa fuel.

RWD is the best when it come with power,traction and Maneuverability. that is why almost or all of BMW engine layout are all RWD, BMW calls FWD as work of Satan according to a recent TG episode.

 

part time.... hmmm meaning its a rwd car with an option to go 4wd usually with 4wd low for severe driving conditions (putik, bato, etc) and 4wd high for slippery surfaces. 4wd can be engaged either using a second shifter or a button in m odern cars. in general, if your car is a part time 4wd, keep it in two wheel drive unless mag o offroad ka. Happy driving, enjoy your new SUV :)

most common among these are configured to run on front wheels on normal conditions and four wheels when the need arises..

Yeah there's a button nga para maging 4wd. Hey thanks for the info. ;)

 

Pansin ko pag matarik yun rampa, parang hirap makina ko pag hindi ko pinepress yun 4wd button. Tama ba yun napi-feel ko o imagination ko lang yun? :unsure:

 

tama naman na fe-feel mo, pero kadalasan kaya on 2wd, but better ang kapit pag 4wd. Happy driving!

Mitsubishi Motors develops S-AWC vehicle dynamics control system

&

Twin Clutch SST automated manual transmission

Tokyo, July 10, 2007

Mitsubishi Motors Corporation has developed two new component

systems that are expected to feature in the new Lancer Evolution*, due to be launched this autumn.

S-AWC (Super All Wheel Control) is an advanced vehicle dynamics control system that regulates

drive torque at each wheel. Twin Clutch SST (Sport Shift Transmission) is an automated manual

transmission that delivers slicker shifting through the gears while freeing the driver from the need to

operate the clutch.

In line with its corporate philosophy, Mitsubishi Motors strives to deliver a dynamic driving

experience while making advances to keep drivers safe. Twin Clutch SST and S-AWC do so by

making driving more intuitive. Both the systems work to efficiently distribute power appropriate to

road conditions, and deliver outstanding control and stability maintained by an “intelligent” system

that reads and reflects driver intent in real time.

S-AWC:

The system now adds an ASC*1 (Active Stability Control) feature to the ACD*2 (Active Center

Differential), AYC*3 (Active Yaw Control) and Sport ABS*4 (Sport Antilock Brake System)

components that have proven themselves in the Lancer Evolution series. Integrated system

management of these four components allows regulation of torque and braking force at each wheel.

S-AWC also now employs yaw rate feedback control. This allows the system to control each wheel

under a wide range of driving conditions, thus realizing vehicle behavior that faithfully reflects driver

inputs and allows drivers of all abilities to enjoy sporty motoring with confidence.

Twin Clutch SST:

MMC’s new automated manual transmission employs dual clutches to realize power transmission

efficiencies on a par with a normal manual gearbox while also allowing slick and swift shifting.

Allowing drivers of all abilities to shift rapidly up and down through the gears, Twin Clutch SST

delivers satisfying acceleration while also returning superior fuel mileage thanks to its

high-efficiency power transmission mechanism. The new transmission also features three

operating modes tailored to different situations: from around-town drivability to instant-response

and follow-the-line sporty motoring on the open road.

*1, *2, *3, *4: see following pages for details

S-AWC system

the difference of the two is that, kung old na yung car, ang rwd e umaangat ang harap pag biglang arangkada, ang fwd bumbagsak naman ang likod..it depends in racing. drifting & slalom maganda ang rwd..my friend said maganda fwd sa drag kasi yung bigat nasa harap, nagbibigay diin sa front wheels to give traction..dunno if true..

The main difference is how they behave when you enter a turn too fast.

 

All other things kept the same, a FWD car will understeer---it will tend to go straight-on instead of continuing into the direction of the turn because the front tires will have lost grip. So you will either have to apply more steering lock or gently let go of the gas to correct its line.

 

A RWD car will tend to oversteer. The tail of the car will step out of line due to lack of grip at the rear, and you will have to counter-steer (steer away from the turn) to correct its line. Such counter-steering is an integral part of drifting.

 

How gradually/sudden the lack of grip occurs is influenced by a number of things: engine placement (front, amidships or rear?), engine characteristics, transmission gearing and chassis tuning.

 

Which one is better? Let's be honest, not many of us can afford RWD performance cars unless you count in Revos, Innovas and other diesel-powered trucks and vans. In terms of space, FWD cars have an advantage, and they can also be driven competitively as long as you understand what happens when you lose traction and what you have to do.

 

RWD cars have their merits but they're not without sacrifices. Owners of the BMW 3-series will know rear legroom has always been a problem. Hey, the rear differential, half-shafts and driveshaft have to go somewhere.

I have 2 RWD cars (MBZ E320 and Porsche Cayman) and one FWD car (Mini Cooper). RWD is more fun to drive and, just being subjective, feels like I can go faster through a turn than a FWD car.

 

With FWD, you will indeed tend to understeer, and when that happens, a bit of judicious braking plus lifting off the accelerator tends to get you back in line. If you lift off too much, however, you WILL spin! While you may not spin when you panic, you will certainly go into a slide where you lose all directionality in the car. And when you finally get it back, you will tend to shoot off into whatever direction your wheels are pointed, and THAT could be a bad surprise!

 

With a RWD car, you give it MORE gas rather than less and you need to make sure you get your line right going into the turn hitting a LATE apex, especially if you learn how to trail brake. If you panic and let off the gas, you will go into a slide, or evne worse, you may go into a spin! But if you (here called for) tap the brakes to front load your car and get the front wheels to bite, then get on the gas (smoothly! Don't hit it hard!) and accelearte through the turn, you can get through nice, smooth and FAST!!!

 

There are LOTS of good RWD cars, and while there is always the drive shaft tunnelto account for, I don't notice less rear seat room in RWD cars than in FWD cars. OVerall, I like RWD MUCH better than FWD. I won't buy another FWD car if i want to engage in any spritied driving at all.

That's only natural. FWD cars have to do two things (accelerating and steering) with one pair of wheels (the front). Hence the RWD purists' claim that the steering of their cars is purer and more natural. That's by design :)

 

Mid-engined cars like your Cayman tend to have less tolerance for "stupidity" behind the wheel. While all RWD cars have the tendency to spin out, mid-engined cars will tend to do so faster because all the weight is within the wheelbase and center of rotation/yaw---the reason why the Elise, NSX, Cayman and MR2 are so maneuverable. Such MR cars need quick-acting drivers when pushed to the limits, though, because of their inherent "naughtiness" compared to FRs.

 

Mind you, there are also understeery FR cars that take a little more effort to get sideways. Most of them are Nissans: the S13 Silvia and the Z33 350Z/Fairlady Z are notable examples. The Mazda RX-8 is another example but that's mainly because its Wankel engine doesn't make enough torque to get its tail out of line.

 

On the other end of the spectrum are "nervous" FRs like the Honda S2000, which steps into oversteer quicker than most people can avoid slamming a wall against. Committed driving in an S2000 reportedly needs a lot of preparation and practice.

FWD understeers a lot compared to RWD, unless you know how to use the e-brake in smooth action lang.. 4wd and awd cars rin also have the tendency to understeer since the front tires might spin during turns and loose traction.. i like rwd because it is easier to accelerate in turns than fwd that is prone to understeer when accelerating in turns.. i never tried the AWD drive or any wrc cars such as evo and sti.. but i heard that an evo can understeer while accelerating in a turn. then rwd may fish tail. but as ive experienced, it is easier to drive a RWD than FWD in corners.. nakakatakot ung understeer that ive experienced pababa ng antipolo..

..according to a japanese racer na napanood ko, RWD is fast in entering corners and good at the exit, AWD (STi tested) is slower in entering the corners since it's heavier but fast in the exit dahil sa power, FWD is slow in entering and harder to accelerate while doing a turn.. test drive nila un sa race track with tight turns. AWD is better kung medyo drift daw like rallying than track driving in a 2-3 lane turns sa track. pero the most important thing he said, malaking factor ung driver and how well you know your car.. but if pipili ako, id still choose RWD. FR dahil para hindi mabigat sa likod as long as the front mount engine is not to heavy dahil baka understeer din.

Actually I've found the mid-engine design to be easier to drive hard into a turn. Good front/real balance and a lower moment of inertia tends to make it more neutral in the turns. The rear-engined cars like the 997s tend to be more tail-happy. The front engine/rear drive cars are a bit light in the rear so you have to be careful to not let the rear end get light in the turns, even more so than in the mid-engine cars. Then for sure your rear end will whip around on you.
