Track Test: Nissan DeltaWing Driven At Road Atlanta by CHRIS HARRIS

http://www.youtube.com/watch?v=c_INdbXMqsw&sns=em

Delta Wing Designer and Nissan show their brave to make a batman race car which has so many new ideas and those are weaknesses on current traditional race cars.

The engineer explained how the car running in a corner, how stable we couldn't expect, how 'enough' on every aspect and how 'balance' they have to achieve.

終於明白喇.
個頭擔咁窄, 入彎嘅內呔就一樣有load, 即係個grip等於有兩條呔咁闊. 而brake時, 個braking force又係中間axis, 唔會引起understeer,
逢星期日...糕-糕-糕.

堅!

Simon, 那麼泰國「獨獨」三輪車應該是零推頭嗎?
個Engineer講到好完美,以你推算,這輛batman車比正常「四方型」的車有什麼死穴?

重心一定要夠低同夠後,否則窄前軸一受則向力就好易失控
好似Top Gear試個架三輪仔,因為FR layout,放副最重既引擎係單前碌上,所以好易反
因為小左一半既車呔,雖然輕人一半,實際剎車距離並冇縮短
灣速特別入灣段什至比GT慢,但可以好早起油
加速反應因為車輕而快,尾段極速因為低風阻而高,但講求扭力同爆發力既中段就因為引擎downsizing而欠奉。但如果做電動版的話可解決此問題
但係耐力賽有個最大優勢,就係入油時間少好多
今年ALMS佢跑LMP1,同其它P1比,就係車速明顯慢,但每一次pit stop window後佢都會走返去人前面
GT6有呢架車,渣法要重新適應,但熟左就好好玩。你踩油時間愈多操控性就愈好

其實講得簡單D,就好似去大尾督踩三輪單車,踩得好快時好快咁扭呔,基本上你唔反就一定轉到灣,反而四輪家庭車既轉向就鈍好多。而設計同配重就係令到佢唔會反

"就好似去大尾督踩三輪單車,踩得好快時好快咁扭呔,基本上你唔反就一定轉到灣", such idea is perfect, therefore there is no more understeer in the world, but any chance of overteer in triangle configuration

可以用gt6試下~
唔好late brake慢慢溜既話好好渣,但一push下就掉頭
