Renault RS18 (text by tw) February 22, 2018

On February 20, 2018, Renault's 2018 machine [R.S.18] was released.
For an overview of this new car, see F1-Gete.com.
I write my opinion below from the overview of the car body.

The question with the front wing is that the inside of the back flap does not cover the inside of the front flap.
As a result, complicated whirlpools will fly to the side deflector, but is this all right?

The discharge port of the nose hall is small, and seems to be lacking in aggressiveness in activation of the air current under the nose.

Front suspension is as usual, pivot of the upper arm is in the wheel.

This year the side pod's under panel front is thick.
This seems to be guiding the air current that collided with the vertical part of the front edge of the under panel to the bottom of the car body.
This probably has no problem.

The front end of the side pod upper surface is as usual, squeezing the air current upward, causing a lift.
At the moment, Renault is the only team not affected by last year's Ferrari side pod.
Why did not they challenge?

As in last year, the air intake of the induction pod was wide, and the lower separator wastefully eats up the volume.
In other words, the air current that should enter the intake is wasted many times, and it separates to the left and right with a separator. This is obviously aerodynamic damage.

I can not see the [Gearbox wing] that is likely to be the trend this year from the photograph.

Perhaps there are plenty of fine aerodynamic tuning at a level that I can not see in amateur like me, there will be gains that I'm likely to fight this year.
But the foundation is too conservative.
Renault will not be able to challenge the top team without making a big update by the opening season.
The driver is a pair of Nico Hülkenberg and Carlos Sainz.
