Mitsubishi's New WRC Weapon

Mitsubishi's New WRC Weapon

On the heels of Mitsubishi's announcement that it was withdrawing support for SCCA Pro Rallying in America, came the Thanksgiving day unveiling of the car that will lead them back into WRC competition during 2004--the Lancer WRC04.

"The car is quite different from our previous World Rally Car," says Mario Fornaris, who oversaw the car's construction at Mitsubishi's Motor Sports subsidiary in Rugby, Great Britain. "We have made something like 6,000 new parts. We have taken advantage of the freedom permitted by the World Rally Car regulations, but my philosophy is to do very simple things and have a good understanding of the car before we introduce more advanced systems."

The most apparent difference with the new car is the slick bodywork that emerged from three weeks of testing in the Lola racing team's wind tunnel. The hood, fascia, fenders and, most dramatically, the rear wing are all brand new. The two elements of the rear wing are both taller and more radical than ever and are sure to be imitated throughout the world of EVO owners.

The 2-liter, DOHC, 16-valve engine is still a member of the 4G6 family of fours and still uses a cast-iron block, alloy head and turbocharger. But the engine is based on the latest version of the 4G6 used in the EVO VIII and the reciprocating assembly is significantly lighter than before. A new Garrett turbocharger breathes in through the required 34mm intake restrictor and feeds a completely new intake system. The engine feeds a new Ricardo five-speed manual (a rarity in WRC) gearbox.

The suspension consists of MacPherson struts at each corner, with Brembo brakes in charge of stopping. The Mitsu will be the only car in WRC without an active center differential. Instead, it runs an epicyclic differential.

The WRCO4 reflects the conservative approach Fornaris took with the car. Innovation isn't something they're pursuing until they've first proved they can finish races. Who knows what will come after they've accomplished that?

Terlalu bongsor utk WRC. Di balap manapun, body bongsor akan berefek buruk pada tikungan. Efek gaya sentrifugal berasa banget. Body jadi limbung keluar tikungan dan menyebabkan mobil lambat saat keluar tikungan.

Selain itu pada track yg tdk rata, jelas body besar akan menyulitkan pada saat melompat. Yg jelas dapat merusak sistem suspensi. Karena pada saat mendarat sebaiknya dgn kondisi sejajar, dalam arti roda depan mendarat bersamaan. Tapi kalu body limbung, otomatis sulit mendarat dgn roda depan bersamaan. Ini jelas akan merusak suspensi. Akibatnya kalu mau mobil awet, driver harus memperlambat mobilnya bila lewat track yg tdk rata.

Gak heran kalu mitsubishi ampe sekarang blom pernah menang... :roll: :roll: :roll: :roll:

Mungkin bener juga yah, kalo body terlalu bongsor / dimensi-nya panjang akan berefek buruk pada tikungan.

Soalnya bukan cuma Mitsubsihi Lancer Evo WRC aja, coba liat deh Peugeot 307cc WRC yang sekarang ini. Spertinya Peugeot 206 WRC masih lebih baik, mengingat dimensinya yang lebih kompak / dimensinya pendek.

Tull... panjang sasis sangat berpengaruh pada saat menghajar tikungan2 sempit. Makin pendek makin lincah. Blom lagi beratnya.. Makin panjang, otomatis relatif makin berat khan?

Gak heran salah satu mobil rally terbaik sepanjang masa, Peugeot 205 punya body ringan abis, dan ukurannya mirip 206. Saking kencangnya, akhirnya dilarang dipakai lagi.... 8) Karena kalu gak juara, pasti nabrak... :lol: :lol: :lol: [boleh baca tabloid otosport edisi lama yg udah ga terbit lagi sekarang]

Walah.. lebih tua Lancia Stratos dunk. Kalu 205 udah 4wd, Lancia khan masih rwd.

Btw, 205 itu mobil jagoan Daku kalu di Collin McRae. Kenceng banget. Cuma sulit dikontrol, soalnya terlalu ringan.... Mirip kondisi aslinya. Kalu gak salah sasisnya dari pipa almu. Jadi ringan banget. Gak heran kalu akselerasinya mirip2 F1. Serem boow.... :roll: :roll: :roll:

Makanya mobil spek WRC sekarang justru lebih pelan dari versi jaman dulu. Karena faktor keamanannya itu yg menyebabkan mobil dulu tidak dipakai lagi.

Akselerasi 205 mirip2 F1 ? Ck ck ck ... huebat bener !

Kan katanya makin pendek makin lincah, tapi koq 307cc dipake buat ralli yah? Ada yang tau ngga knp?

Anyway, Citroen C2 WRC bodinya kan panjang (hampir sama dengan 307cc). Tapi koq dia bisa unggul terus ya?

Yups... karena bodynya ringan, en sasis dari aluminum. Cuma jadinya gampang terbang...

Soal panjang sasis kalau terlalu pendek jg malah ngerepotin lho. Ambil contoh pada off road. Wrangler malah susah diajak lewat medan off road. Karena sasis pendek, maka doi gampang melintir kemana-mana. Sebaliknya Hummer dgn sasis panjang dan besar, lebih stabil dan enak diajak naek gunung. (Pengalaman dari game-game off road)

So.. kesimpulannya panjang 307 masih cukup memadai utk Rally. Disamping itu ada faktor ekonomis. Karena tujuan ikut Rally jelas sebagai ajang promosi jg. Tertarik dgn sukses 206 di pasaran, maka 307 ingin ikut2an sukses jg dunk....

Thanks bung anjas buat info2nya.

To : Demo

Emang mungkin juga ya faktor luck (kubu Citroen). Soalnya kan taon lalu Citroen jadi juara 1, baru diikuti Peugeot. Smoga aja taon ini Peugeot bisa memperbaiki reputasinya dengan mobil baru (307cc).
