【三菱ランサーエボリューションIX プロトタイプ速報】MIVECターボでモノにした全域高性能…河口まなぶ
2004年12月27日
いっぽう見た目以上に、中身にこだわるのがランエボのランエボたる所以でもある。とく藤井氏(乗用車開発本 部)は「MRをベースに」という部分を強調しながらハナシを始めた。なぜなら、「じつはMRというのは、I Xで入れる予定だったものを大分入れたモデルだったのです。その意味でも今回のIXはあくまでMRをベース にしていることを強調しています」とのこと。
そのうえで、MIVECターボエンジン搭載による全域高性能の実現と、これによる動力性能における走りの質 感向上を謳うわけだ。
「MIVEC化は、これまでの4G63のヘッドを変更することで行なっています。だから形式名こそ今まで通 りの4G63ですが、乗ればすぐに違いがわかってもらえるはずです」
インテーク側に可変バルタイを採用したことで、MRの高回転の伸びを犠牲にせずに低中速トルクの向上を図り 、実用域から高回転域までフラットなトルク特性を実現。WRCからのフィードバックによりターボのコンプレ ッサーハウジングの形状を最適化し、低中速の性能向上を図った。さらにコンプレッサー側を軽量化することで 過給レスポンスをアップ。
「VVTとターボによって3000rpmまでトルクも一枚上手。さらに高速ではVVTが効果を発揮すること で全域高性能を実現しました。このあたりはWRカーが中速メインだという特性をフィードバックさせた結果で す。同時に今回の改良で排ガス・燃費性能もアップしたのでそのぶん触媒を見直し、排ガスは以前と同レベルと して背圧を下げる方向に使いました」という。
形式こそ同じだが、その進化ぶりは圧倒的。コーナーからの立ち上がりにおけるエンジンのツキがMRとは段違 い。つまり、これまでは立ち上がりでわずかな「待ち」を感じたが、それが解消されたのだ。(つ づく)

I like everything they did to the front and rear bumpers....Can't wait to graduate college in May 05 so I can get mine!!!!!!!!
My question though is some one posted 280hp...The mivec only adds 4 hp over the 05????

I did not see one the video with Pannizi driving just this test footage one I wonder why maybe they scratched it from final car like in the Pannizi video.

Id say it would a bit more then 4hp, but the Mivec will bump the Torque up 20%. I just realised, whats up with using the 8's bonnet (hood) again? Still got that little rise in the middle from where the fugly VIII nose thing was

AYC
AYC is good, but not indispensable by any means. The S-AYC system on my car puts up a fight when I intentionally attempt to powerslide the car doing autokhana-style turns. And the Japs do not 'swear by it.' Masaki Nishihara (5-time Japanese AutoKhana Champion) would have pulled the AYC wires if it wasn't my car, and the purpose-built Evos who run autokhanas here have mechanical LSDs all round.
MIVEC
Would be a great addition if you do not intend to tune the car. But to me its an additional parameter (read:complication) for EMS tuning especially for forced-induction motors. Ever wondered why TurboXS took so long to release their UTEC for the STI? Yes, AVCS was a b1tch to hack. And here, many S14 and S15 owners actually swap out their heads for the S13 ones simply because the NVCS-equipped S14 / S15 head is a tuner's nightmare for high-horsepower applications.
That said, I've been informed that a Evo IX is due here in '2 weeks.' Watch this space.

Guys remember mitsu's way, although japan is getting mivec doesn't necessarily means that we will get it. They will most likely offer it as a different edition to maximize their profit. Thet may call it evo ralliart with the mivec engine. Let's all pray that it will not be the case.
