more specific for the second generation Corollas. I did my best to find pics of some non standard examples to illustrate 😉
Japan’s growing middle class thought the Publica (Toyota’s entry-level car in the early 1960’s) was too boring while the Crown and Corona were too expensive for them. Tatsuo Hasegawa, a Toyota engineer, designed the Corollas’ ideas. It was sized between the Publica (700cc) and Corona (1500cc), looked classy, had modest power, yet was economical and inexpensive.
The Corolla was sold under 2 names – “Corolla” and “Sprinter”. The Corolla was offered as a 4 door sedan, a 2 door sedan and a 2 door van but not as a fastback coupe. The Sprinter (never called a Corolla in Japan, but sharing most parts) was offered only as a fastback coupe.
Corolla means the crown of a flower. This can be found in many old Corolla logos with a C wich is crowned by 3 flowers.
2nd GENERATION (MAY 1970-July 1978) :
Mechanically very similar to the 1st generation, the body received a substantial facelift. The coupe was added to the Corolla range (no longer just as the Sprinter). Likewise, the Sprinter gained 2 and 4 door sedan versions. The differences between the Corolla and the Sprinter were mostly cosmetic. The Corolla and Sprinter both came in multiple grades (eg Standard, Deluxe, Hi-Deluxe, SL, SR).
The 2T-G engine was offered only on the Corolla Levin coupe and the Sprinter Trueno coupe. Effectively, the Levin was the GT grade for the Corolla and the Trueno was the GT grade for the Sprinter. The Levin and Trueno also had minor trim differences. The Levin was never sold as a Sprinter and the Trueno was never sold as a Corolla.
So lets start by the different chassis codes for the second generation Corolla’s
First letter “K” or “T” stands for the engine type that’s used
Second letter “E” is for all Corollas
First number “2” determines the generation. 2nd gen Corollas were built from 1970-1978 with a facelift in September 1971
- 2 door Limo Corolla KE20 (3K-D ; 3K-B ; 3K-BR) and TE20(1T)/TE21(2T-C)
they are also called peanuts.
- 4 door Limo Corolla KE20 (3K-D ; 3K-B ; 3K-BR) and TE20(1T)/TE21(2T-C)
- 2 door Coupe Corolla KE25 (3K-D ; 3K-B ; 3K-BR) and TE25 (1T)
these are also called Mangos
All these came as Zenki and Kouki models. Before and after 1972. There where lots of differences between years, models, trims,… As always with older Toyotas, there is a multitude styles: different grills, headlight trims, hoods, rear lights, emblems,…
And just to show you how many variants Toyota offered there buyers bach in the days. Here are the light and garnish differences just for the TE27 models.
