RWD vs AWD vs FWD
-
i'd like to consult regarding the differences among these 3.
my personal analysis is as follows:
RWD
Pros:
- less tendency of wheelspin at launch as compared to FWD due to overwhelming power from engine (hence most supercars are RWD)
- less tendency to understeer
Cons:
- more tendency to oversteer
AWD
Pros:
- handling
Cons:
- higher FC
- higher cost
FWD
Pros:
- easier to control at corners as compared to RWD (hence mainstream cars are FWD)
Cons:
- more tendency to understeer
hope someone can give me the full idea, and correct any misconception of mine. thanks

The placement of the driving wheels does make for a difference in oversteering or understeering, although suspension and tyre setup can (to some extent) reduce such differences. As for wheelspin, I doubt if it makes for much of a difference - if inertia exceeds grip at the applied torque, you're going to get wheelspin no matter what.
-
if i am not wrong for example two cars(with same engine,engine in front,same torque and hp)car with FF layout will have lesser chance of wheelspin than FR as the engine weight is giving more pressure on the front wheel so more grip than FR on the front wheel...
thats y cars engineer design the MR and RR layout for better pick up for cars with RWD..
am i wrong anyone can clear my doubts -
well AWD also remember...higher maintainence....cos more moving parts....and weight also....and AWD does not mean u have all the handling in the world....dunno id u seen a test where they did 2 runs... 1 in a carerra and a carerra 4.....the 4wd was slower in the tighter turns as opposed 2 the Rwd version...anyway the whole package also matters....chassis rigidity...suspension etc....all have to be balanced....u look at the focus ST and the Mini....both are FWD but they dun show their FWD understeer weakness...which explains my pt

Front wheel drive cars aren't necessarily easier to control. You can still oversteer in them.
They're used in mainstream cars is because they eliminate the need for a propellor shaft, which adds weight and costs and consumes some cabin space (hence a transmission tunnel in RWD and 4WD cars). And it is the logical choice when a transverse engine layout is used. -
traction too play a very important role in gripping n drafting/drifting
yes true super cars lyk GT machines r RWD
since all 3 have their pros n cons it all boils down to one preerences n how well r u able to handle each individual well.. -
if im worng do correct me..
still learning automotive humbly
if im nt wrong tranction for rwd has to b more applied on the front wheels during drifting hence to prevent the rear from flying out too much...tats to prevent a 360deg spin..
CORRECT ME..thanks

thanks for the replies.
can anyone explain what are the differing philosophies between Ferrari producing RWD cars & Lamborghini producing AWD cars?
and what is exactly the clear advantage RWD has over FWD that recent new cars like the IS250 and Mark X have been boasting about?
one last case study. just within the Volks Golf range, they have FWD for the GTi and AWD for the R32. what's their objective? -
wa..getting more n more chim...nah i dun study italian cars..
dun tell me ur getting a FEERARI?
man the best thign about the car is its interior gear!
on the steer wheel -
u sure golf GTI is RWD???Originally posted by Theatre Of Dreams:thanks for the replies.

haha ya if there's a pirated version of FERRARI called FEERARI that is affordable to me than i'll getOriginally posted by olala:wa..getting more n more chim...nah i dun study italian cars..

well asking merely to learn la. haha i don't even have the ability to own the cheapest car in the market yet... -
oppsOriginally posted by AE86tofu:u sure golf GTI is RWD???
FWD sorry -
i remember reading a books about the cons of FWD is that the pick up for FWD in the first 1/4 mile will lose out to RWD cause of the weight transfer to the back thus losing gripOriginally posted by Theatre Of Dreams:thanks for the replies.

This one got to ask honda leh. Why their nsx and s2000 in rwd and the rest in ff?
-
RWD is better 2 turn but twitchy in the wet or when there are sudden inputs.....but nowadays traction controls counter that....
-
All things being equal, the oversteer produced by RWD cars does make them a bit more fun to drive, provided that one's driving skills are up to the job. That said, one can have a fair bit of fun flinging a FWD car round corners as well.

yaya..i was wondering too and y they hate force induction...hahahhahaOriginally posted by ditzy:This one got to ask honda leh. Why their nsx and s2000 in rwd and the rest in ff? -
Huh?!? You mean you dunno why ar? Never mind, I let you go and find out.Originally posted by tofushop193:yaya..i was wondering too and y they hate force induction...hahahhaha -
erm sorry guys but juz to enquire...
wats the diff between the endless tyres which can b used in R34 n the advan RG

Ferrari don't have any 4WD drivetrain of their own, and unlike VAG, they won't think of sharing components with lesser models. VAG have been using 4WD as a unique selling point in their road-going cars for a while now, and in real life, it means there is drive to all 4 wheels - which is useful in bad weather and accelerating out of corners.
The Stig drove a Porsche 911 C2 and C4 around the Race of Champions circuit at Cardiff last year, and the C4 was only a tenth slower despite the weight penalty.
RWD cars inherently have a better front-rear weight distribution. And since the front wheels don't have to deal with both forward propulsion and steering like FWD cars, they don't run out of front-wheel grip (i.e. understeer) as easily.
The large engine in the R32 endows it with lots of torque, and 4WD drivetrain reduces the chance of torque steer (when the front wheels start turning on their own under acceleration) occuring. -
but of course.....4WD is the way to go man....grip grip and more grip.....there was one season where F1 used 4wd but then it was shelved as it made the car too heavy...bruce mclaren said that driving that 4wd F1 car was like drving an F1 car weighed down with bags of sand

nowadays most cars esp in low ends segements used ff cos it is chaper to produce.. easier to maintain.. and the differential could be in the same one unit as the eninge.. thus less complication.. but the biggest plus wld be space saving with the elimination of prop shaft and rear differential box... also the engine in a ff car could be mounted tranversely... thereby opening up space for front passengers.. but the downside is its tendency to understeer like u said and the front wheels more easily wear out....
rwd have better weight distrubition and better handling.. and is prefered in luxury cars.. but is harder to control for beggineers cos of its tendency to oversteer (ie oversteering is harder to rectify than understeering ) also in low traction conditions an FF will save ur life rather than a FR vehicle...
AWD has better traction control cos torque is spread to all 4wheels.. handling is better.. but 4wd vehicles have veh complicated drivetrains tt needs a total of 3 differentials boxes.. thus also adding to the weight of the vehicle... -
not just that....if damaged or what...expensive 2 repair or replaceOriginally posted by n0x:nowadays most cars esp in low ends segements used ff cos it is chaper to produce.. easier to maintain.. and the differential could be in the same one unit as the eninge.. thus less complication.. but the biggest plus wld be space saving with the elimination of prop shaft and rear differential box... also the engine in a ff car could be mounted tranversely... thereby opening up space for front passengers.. but the downside is its tendency to understeer like u said and the front wheels more easily wear out....

wow thanks for the extensive explanations people.
you guys are the men

now most supercars awd..
