Dnes mi kamos vnukol myslienku. Bavili sme sa o tom, ci ma vyznam "tunit" moje auto aj nadalej (racing podvozok, zvody, polyuretanove silenty, tuhsie stabilizatory, vacsie brzdy atd atd.)
Casom by som chcel vyskusat ring takze touto problematikou som sa zaoberal uz davnejsie. Uz pred casom som si zistoval, ci su na tom touringy az tak zle v ramci handlingu a tuhosti kasne a zacal som sa v tom sprtat viac. Neraz som sa stretol s nazrom, ze coup je to prave orechove ak sa jedna o zakruty alebo trat a ze coupe "outhandluje" sedan aj touring pritom coupe zdiela rovnaky podovozk ako sedan a touring a co sa tuhosti kasne tyka, nieje na tom najlepsie.

Prikladam sem niekolko clankov, kto vie anglicky, moze citat. Je tam vela nazorov aj od ludi, ktori vlastnili coupe aj sedan aj touring zaroven, ktori chodili na trat si zajazdit aj so sedanom aj s touringom. Niesu to nicim podlozene informacie, ide len o nazory ludi, ktori vyskusali rozne varianty aj mimo denneho jazdenia (na trati).

Coupe je az prilis precenovane a touring podcenovany. Uvitam aj diskusiu alebo nejake ine clanky a zaujimavosti.

Davam to sem ako zaujimave citanie a nie ako podnet na flame. Ak neovladate anglictinu, tak tuto temu ignorujte a nepiste sem, ze to chcete po slovensky. Existuje translator alebo slovnik.
Taktiez poprosim prispevky k veci, nech je to tu prehladne.

E46 Touring vs E36 m3 - zaujimava debata :
http://forums.bimmerforums.com/forum/sh ... han-E36-M3

Zaujimave prispevky :

"The best handling e46 chassis would be a non-sunroof 328i sedan with sport package and no fold-down seats. 330 is heavier (by some amount) otherwise I would have said 330 sedan.

Sedans are better than coupes because they have the added rigidity of the B-pillar. If you took a coupe and welded a mini roll cage in front of the doors/windows to act as a B-pillar, then it would be equal"

***********************

" One trick in racing is to get a sun/moon roof car, then weld in a metal panel to replace it, but leaving the factory reinforcment for the hole. Makes an even MORE rigid car, but at the expense of some wieght up high.

But basically Coupe look better, and more sporty. But the large door openings and less rigid B pillar do hurt."

***********************

"For the E36, the coupe shared several primary body (note: not necessarily body PANEL) components with the sedan. The E46 coupe was, purportedly, more of a departure from the sedan than in its previous (E36) incarnation.

The touring has an exceptionally stiff bodyshell, given its structure; these sorts of things tend to indicate that the 3er was designed to be available in a 5-door variant right from the beginning. Previous 3ers 5-door bodystyles, ini particular the E30, were offshoots of the sedan shape.

Not since the E30 has the two-door (not coupe; that terminology came later) been released first."

Sekcia E9x :

E90M3 vs E92M3 :
1. http://www.m3post.com/forums/showthread.php?t=267531
2. http://www.e90post.com/forums/showthread.php?t=489793

Vynatok (viac v linku) :

"Track-------------------------M3 (E92)=== M3 Sedan (E90)
Tsukuba--------------------- 1:05.817=== 1:06.154
Hockenheim Short-- ---------- 1:14.3=== 1:15.2
Vairano Handling Course-- 1:20.910 ===1:20.276
Autozeitung test track -------- 1:40.1=== 1:38.7
Inta --------------------------- 1:12.36=== 1:11.75

The E90 is about 60 lbs heavier and therefore very slightly slower in a straight line."

***********

"The theory has always been (back to E36 days) that the 3 Series Saloon handles better. This was apparently because of a stiffening beam across the Saloon that the Coupe lacks, beneath the seats.

It was kind of proven back then because the Saloon seats wouldn't fold down and coupe's would (or vice versa) because said beam wouldn't allow it due to how the seat was placed etc.

I'm not sure if this still applies to the E9X. I do find the Coupe crashier though."

Konecne nejaka zaujimava tema v tomto pokeci.

Spomina sa tam niekde aj E46 M3? Prave preto, ze je to coupe ma zaujima, ci ma karoseriu menej schopnu, nez sedan bez skl. sedaciek.

To som nezistoval, ale ak ma pamat neklame, m3 ma Xbrace, sirsie napravy a predpokladam, ze aj kasna bude inak stavana.
Skusim pogooglit.

To by chcelo porovnat M3 e90 a e92 su to rovnake auta s rovnakymi komponentmi akurat kasne ine.

Kludne sem pridavajte napady / linky. Myslim, ze to moze byt zaujimava tema v ramci vsetkych modelov.

Vsetko budem davat do prveho prispevku, ak tu toho bude viac.

Nasiel som nieco ohladne M3, takze pre Teba Igmaus. Doplnene do prveho prispevku.

Citanie je to nepochybne informativne, no mam pochybnosti o pravdivosti niektorych cisel. Trebars take Lambo Countach alebo McLaren F1. Nechce sa mi verit, ze karbonovy monokok a celkovo vyvoj, ktory isiel do F1 je porovnatelny s kombikom E36. Alebo Countach - 2600nm je udaj, ktory sa da zvysit, ak si vodic sadne do auta obleceny v hrubej kozenej bunde.

Ale ako vravim, citanie je to informativne.

To vyzera dobre, dik.
Pridam do prveho prispevku.

Inak, patrilo by sa tuto skvelu temu obohatit o poznanie co to vlastne tuhost karoserie je.
Tak podme na to:



Toto video to znazornuje velmi pekne a velmi principialne:
http://www.youtube.com/watch?v=0K7C9-e0Dcc - kto nechce pocuvat reci nech si usetri cas a da si to od 1:10 (kazdy z truckov ma na korbe nalozenych 3000 libier = 1362 kg nakladu)
http://www.youtube.com/watch?v=El0SJwZahT0 - velmi nevedecky, ale infomativny a vtipny sposob testovania tuhosti

Podla toho ako tomu rozumiem ja si tuhost karoserie mozeme principialne predstavit ako dosku, ktora je upevnena na jednom konci v strede a na druhom konci je ohybana hore a dole, kym vysledok bude ohybanie materialu do stran - ako ked sa naklanate pri jazde na bicykli. Sila, ktoru bude potrebnu vyvinut na to, aby sa zacal material ohybat bude vyjadrena ako tuhost materialu. Teda, mozem sa mylit, ale takto tomu rozumiem.


Z toho vsetkeho nam vyplyva to, ze pokial by ste Lamborghini Countach zaparkovali na nerovnom a znacne prevysenom vymoli, mohlo by sa stat, ze by ste neotvorili dvere.

hm zaujimave čitanie + video nečakal som že až tak mu vyjebe kasnu
