Renault21 (Vingt et un) came out in March 1986, as the succession of Renault18 .
The Renault 21 TURBO is the sporty version that was released in the next year was added in 1987 .
It features a square bodystyle unlike the car that came out in the later of '1980s
and that is the only 4 door sedan of 3-box, 6-light with an independent trunk in the lineup of Renault .
The TURBO is equiped with many body styling parts in comparison with a standard type
and therefore it puts out unusual power .
It has the finer CD value unlike the square body is 0.31 .
Its inside is desinged to make much of a habitability and fairly wide for the middle class .
Its trunk is designed for satisfy user comforts like a contemporary car .
: the trunk opens by bumper level
: the rear seat can fold down through the trunk .
Its performance compete with "BMW M3" , "MERCEDES 190E2.3-16" and its speed surpassed substantially
"CITROEN BX GTI16 valve" , "PSA of PEUGEOT 405Mi16" of 2 NA 16 valve versions that came out in the same time in France.
The turbochange is definitely Renault style, when the engine exceeds 3000rpm , the force presses you against the sheet ,
that is feature of the turboengine.
The going straight stability is good on wheel basis 2600mm , the sense of security increases indeed to a high speed .
However , the steering picks up a track under the bad road condition .
You can't handling well in your one hand .
In the handling you must grapple with the constant strong torque steering as often seen in the high powerd FF .
(This is improved a little form 1990)
If you have the strength to press down the power , its under steering is included to a light group .
Although the rolling is held down to a minimum with a hard setting suspention ,
its front is sometimes hard to manage when full power is applied at tight corner .
Quadra was released in 1990 , it is full-time 4WD with center DEFF and viscous LSD ,
that was great imprubed of its truction .
In japan they were introduced by Renault Imp Japan(JAX) from 1988 .
It was 1989 that the sales organization was arranged actually .
After LAGUNA came out as the succession of Renault 21 , its production was over in 1992 .
Its import to Japan was ended due to JAX backed out in 1993 .
