下一代Lexus LS旗艦房車(代號XF50),將在明年上半年發表,並以2018年式的名義上市
。現行LS旗艦老兵戰了十年,小改款兩次,明年總算可以退休了。
而下一代Lexus GS(代號L20),將在2018年,用2019年式之名發表,
維持GS 6年一次大改款的步調。

新LS和GS的底盤和動力大升級,將導入全新底盤、新V6渦輪引擎,
LS還有10速自排變速箱。

「全新雙渦輪3.0T V6引擎 400匹」
下一代Lexus LS和GS都會導入全新3.0T V6雙渦輪引擎,馬力400匹多,扭力45.0公斤.米
,新引擎代號為943F。
雖然LS首度V6化,但Lexus LS並沒有放棄1989年LS問世當年的初衷--堅持大排氣量V8
引擎。
新LS車系仍會有LS500 5.0 V8自然進氣引擎467匹、扭力53.8公斤.米的高階款,
3.0T V6渦輪是LS入門款,兩款引擎的變速箱都是Aisin十速自排。
另外LS還有3.5L V6油電引擎版本,搭配全新的變速箱是「ECVT+4速自排」的組合。
下一代Lexus GS200t引擎仍然是現有的8AR-FTS,245匹馬力不變,
但會提升扭力到37.3公斤.米。
下一代GS的車身規格,長寬高 4950 x 1880 x 1430mm,軸距2880mm。
「導入GA-L platform底盤架構,輕量化、高剛性」
底盤方面,下一代Lexus LS和GS都是採用全新研發的GA-L platform底盤架構,
前雙A臂+雙連結上支臂,後多連桿。GA-L架構強調輕量化、高剛性、低重心、高運動性能
,GA-L是源自於Lexus LC500雙門豪華轎跑車。
新Lexus LS強調輕量化、高剛性,新LS的車身剛性超越賓士S和勞斯萊斯,
將達到45,000 Nm/deg以上。
即使剛性較高,新LS車重也不會比對手重,高階款的LS500 5.0 V8的車重約1950kg,
跟同級對手賓士S500的1920kg在伯仲之間。
(註: 目前剛性最強的轎車是勞斯萊斯Phantom和賓士W222 S-class,
剛性都是40,500Nm/deg)
新LS車身構造大量採用極高強度鋼材ultra high strength steel (UHSS) 、
高強度鋼材high strength steel (HSS)、鋁合金和碳纖維。
這次LS大改款會拖好幾年的原因是Toyota社長豐田章男對底盤操控的堅持,
他要求新一代Lexus要有很棒的操控表現,能讓Lexus車主露出滿意的微笑。
In short, he wanted Lexus engineers to build a car to bring a smile
to drivers' faces.
他要研發團隊用心開發Lexus LC500雙門豪華轎跑車的底盤,代號為GA-L platform
的底盤架構。
GA-L platform底盤架構的目標是輕量化、高剛性、低重心,以及優良的運動性能。

為了確保Lexus LC500的操控表現能達到高水準,在底盤開發的過程中,
豐田章男本人還要親自試駕,他會把不滿意的地方回報給工程師,要他們回去作出改良,
然後下次再來,直到他本人滿意為止。
這件事是美國Autoblog的記者Andrew在試駕Lexus LC500原型車的時候,
LC500開發案的總工程師「佐藤恒治」(吐苦水)說的。
(註: 豐田章男本人有FIA A級國際賽車駕照,具備Formula 3和GP2賽車的資格。
他應該是各大車廠CEO中最熱血的)
等到LC500的底盤開發完成後,Lexus的開發人員再以LC500的GA-L platform底盤架構
為基礎,來開發下一代LS和GS。

在賽道上試駕完LC500原型車後,Andrew認為跟同場的BMW 650i對照比較起來,
LC500的表現真的不錯。
"it wasn't horribly outclassed and it compared really well with BMW's 6 Series.

這一代的Lexus GS底盤操控本來就很好了,
美國Motor Trend的試駕報導,史上第一次,GS首度擊敗BMW 5系列
GS 350 F-Sport評價勝過BMW 535i M底盤套件和Audi A6 3.0T Quattro。
相信下一代GS導入GA-L架構後,操控會向上提升。
