Why AE86 (Hachi-Roku) is called so ?

[原文轉載]
The AE86 generation of the Toyota Corolla Levin and Toyota Sprinter Trueno is a small,lightweight coupe introduced by Toyota in 1983 as part of the fifth generation Toyota Corolla line-up. For the purpose of brevity, the insider-chassis code "AE86" is used to describe the whole range. In classic Toyota code, the "A" represents the engine that came in the car (the 4A) and the E86 represents the 6th revision of the fifth generation (E80 series) of the E model which is the Corolla. The main difference between the Levin and Trueno is that the former has fixed-headlights whilst the latter has pop-up headlights; the export Corolla name covers both variations. The AE86 (along with the lower spec 1452 cc AE85 versions) was rear wheel drive (unlike the front wheel drive AE82 models), and is among the last rear-drive cars of its type, at a time when most passenger cars were being switched to front-drive. The AE86 was replaced in 1987 by the front wheel drive AE92 Corolla/Sprinter range. The car was also known as the Hachi-Roku (ハチロク, Hachi-Roku?) (after the numbers eight (ハチ, hachi) and six (ロク, roku) in Japanese).

AE86其實是TOYOTA為了要簡要說明此車的特徵－車身－引擎而命名的 . 其中 AE86 的 "A"表示其所使用的引擎是A系列(AE86採用4A系列) , E86 則是指第五代E車身的第六版 (E80系列), 而E車身則指的是Coralla .

排氣量 : 1.6L (1587cc)
汽門數 : 單凸輪軸 8汽門 至 雙凸輪軸20氣門
單凸輪軸 8汽門 , 即 SOHC , 每缸 2-valve , 一進一出
雙凸輪軸20氣門, 即 DOHC , 每缸 5-valve , 三進二出
馬力輸出 : 從4A-C 的70 hp (52 kW) / 4800 轉 到 機械增壓的4A-GZE170 hp (127 kW) /6400 轉

(小常識 : 1KW = 1.34 馬力 , 馬力 簡稱 bhp 或 hp 或 ps)
