Is there difference of turning radius in Japanese vs Locally assembled cars?

[huzaifajalali]

I heard from somebody that this is specially a factor in Toyotas. The Japanese Toyota Corolla will have a shorter turning radius than the locally assembled car of same model.
Is this true, if so why does it happen?

[horticulturalist]

Every make n model has its own turning radius, depends upon the track width, wheel base and the maximum angle of turn. I have experienced the best TR in vitz-14, Alto-12 pkdm, corolla-82, while the worst in mehran-13 and khyber-90.

sir it is a new theory just came to know from your post. do you have a weblink or connecting document source to such news please share.

as per spec sheets of US/Canadian & PKDM Honda Civic physical mechanical dimensions are identical. Engine and accessories options have wide range to select from in US/Canadian models only.

[usman_arooq2]

Japanese Corolla has slightly shorter dimensions than global corolla, upto indus shape the turning radius is same as dimensions are same.

Corolla X, Axio etc have slightly shorter turning radius compared to global models of corolla.

I can vouch for khyber, parallel parking in one go, khyber requires about same space as honda city 5th generation.

[huzaifajalali]

Sorry sir, don't have supporting links.
A friends told me this, I find it hard to believe. I posted on the forum to confirm this.

[PKTUN]

size of vehicle corresponds to turning radius.

khyber requires about same space as honda city 5th generation.

parking space of Honda city is equal to khyber sir you are not serious are you. Ford Mustang parking fits in space of KIA picanto sure when there is no cars around.

[usman_arooq2]

Read my words carefully again to comprehend, I was talking about space required to parallel park

This is parallel parking

And parallel parking depends on turning radius as much as vehicle's length.

Khyber's turning radius is large for its size, to move it into a parallel parking space in "one go" the parking space needs to be quite longer than length of the vehicle suggests.

"One go" means just one reverse and a short forward movement to tuck in the front.

If u still don't understand, take some driving classes.

[PKTUN]

I was talking about space required to parallel park

and the topic is about turning radius not parking.
Thank you for your 'wisdom'

[usman_arooq2]

Turning radius is the amount of space required for a car to make a complete circle at full steering lock in either direction,

It affects maneuverability

A car with large turning radius even if it's smaller requires more space for maneuvers than a larger vehicle with smaller turning radius

E.g. 9th generation Corolla (2002-2007) and 5th generation honda city (2009-2021) both have almost same dimensions externally (city being slightly longer, corolla being slighlty wider) but when making a u turn or parking in a tight space the city is easier to maneuver,

Older cars like mehran, khyber, cultus, older 90s city, civic and corolla had large turning radius means a u turn, tight parallel parking that wagon r, japanese kei cars can do quite easily in "one go", while a mehran, khyber, cultus one has to reverse and forward because the car can't turn as tight, requires more space for the same maneuvor.

And because newer generation vehicles have good (smaller or same) turning radius as older generation vehicles that's why u can see despite current compact sedans outgrowing 90s mid size sedans in external dimensions they still can be driven in tight streets and turns with much ease compared to older, smaller (compared to current compact sedans) midsize sedans.

[horticulturalist]

But how does it make sense? that "khybers turning radius is large for its size?
The lesser the TR, the easier it is to dodge and park. Right?

[usman_arooq2]

While answering you, instead of a new reply I accidentally editted my previous reply, but i explained the concept in detail so u can read that.

Idk why @PKTUN got triggered (my assumption is he's a honda city fan thinking I'm calling city a small ride) while what i actually explained was Honda city has sharper handling characteristics so it's easier to park in tight spaces. Khyber has a large turning radius so it requires the owner to do more muscle work and effort to fit in the same parking space. (Means it can't park in same space as current crop of hatchbacks in one go, it either requires more space or more front and reverse lock to lock manuevers) so if a khyber driver is looking to parallel park the vehicle in "one go" with ease, he has to look for a space about as big where one could fit a honda city with some sharp skills.

[usman_arooq2]

Yes and u couldn't grasp the concept of turning radius so I had to explain it's practical implications in everyday usage. Cheers

Are you comparing a factory issued suzuki khyber with original wheels and tires? Or a car with wider wheels with wrong offset?

Comparing a good suspension car or worn sloppy bushings?

[Xulfiqar]

Im going to use the ultimate turning radius machine

Mercedes w140 s class, it turns tighter than an alto, and is the same when delivered in Pakistan or Germany or Us or UAE

[usman_arooq2]

I've owned a khyber (bought by our family but rarely driven, was about 30k driven when passed to me and I put another 40k km on it), and also kept multiple 5th gen city's,

still own a 2021 5th gen honda city for the sole reason it's quite easy to navigate and park in tight spaces.

And Sir I can vouch that the khyber I owned: suspension was kept in top nick, and worn out parts, bushes were replaced / repaired as close to factory spec parts as I could do in Pakistan. When I couldn't find time to maintain it anymore I let it go in 2018 to a relative, and right now, suspension wise it is in that sloppy worn out condition, as I recently got to drive it and it had way more bodyroll than it ever had + it felt like dampening rate of front left and front right strut is quite different when I went over some speedbreakers, I asked that relative about it and he told me he got the shocks + rack I had on it when I sold the vehicle replaced with some "kabuli" ones his mechanic recommended, the car rebounded approximately 3 times when I pressed down it's fenders.

And yes it turned wider too.

Under my ownership it drove quite like it's supposed to, (good cornering, grip, high speed stability) with steelies on 12R145 or 12R165 width tyres (165 width in 12" of reputed Japanese brands, availability has been on and off in Pakistan, chinese no name brands are plenty though).

[Xulfiqar]

So you are saying that a japanese khyber/swift (sa310) turned tighter than a desi made khyber?

[usman_arooq2]

Not at all, my first reply to this post I said that Indus & Japanese made 7th generation corolla have same turning radius, it's the later model corollas when global corolla outgrew jdm corolla, there's a small difference.

My point with bringing a khyber in discussion was that despite growth in size in all directions modern cars like a 5th generation City have good turning radius compared to cars designed in 80s and 90s and even early 2000s (excluding MB W140, MB was at top of its game in 80s and 90s. They don't make like that anymore)

[capsat]

Mercedes w140 s class, it turns tighter than an alto,

under the analogy of turning radius by the member you can squeeze that S class in a sandwich space required for an alto or a honda city.

[usman_arooq2]

My analogy was about space required to make a maneuver in "one go" and moving a vehicle ofcourse means there's some distance to the objects (other vehicles) in the direction it's being moved,

I repeat I didn't say once about how much space the vehicle actually takes as a static object.

After parking a vehicle, u can park a car in front and a car on its back almost touching its bumpers then tell me can u move the car out of that space? Nope.

So the space I'm talking about is obviously greater than size of honda city obviously Unless we're talking about this:
