During Pre-season testing many people wondered how powerful the slipstream might be with these new wake friendly aero regulated cars. Some also wondered how powerful the DRS might be following in the slipstream. I did a post on this some time ago.#F1Tech
The battle between @Max33Verstappen and @Charles_Leclerc was really fun to watch. Not only did we see the new regulations working quite well, but we saw just how powerful DRS still is. #F1Tech

The best comparison to use comes from the battle along the the pit lane straight where Max had a few goes at Charles. In this first image MV has DRS and stays in the slipstream before stepping out late and reaches a peak speed of 331 kph. #F1Tech
In this next run out of T27, MV stays much closer to CL and passes with DRS out of the slipstream. In clean air, we see that MV reaches a peak speed of 327 kph before braking for T1. #F1Tech
Although not completely conclusive, we can see that even with DRS open, the slipstream is still powerful. Even though the wake is somewhat narrowed, we can assume that the slipstream is still the best place to be when attacking.

Would love to hear your thoughts on this, or maybe any interesting telemetry from other battles to analyze also!

@DANIELEALOFAN Made a great overlay of what the #LasVegasGP track layout could be like in 2023, so I decided to use this as a go-by and add some turn numbers. Let's take a Google Maps tour of the circuit! #F1 Image
The starting line and T1-T3 section looks to be in a currently vacant field where tarmac will surely be laid down. This could change, but interesting nonetheless and has lots of potential. #LasVegasGP Image
The Turn 4 exit takes us to Koval Lane which is around 1km in length from T4 to T5. Our first potential DRS Zone #LasVegasGP Image

The rumors about the @MercedesAMGF1 being updated without a side pod and comments to @ScarbsTech mad scientist Merc drawings, showed me some explanation of the aero influence side pods have is worthwhile. So let's dig more into this #F1Tech thread.

For open wheel racers, one especially problematic geometric element is the front tires. A source of drag, and wake turbulence, the control of the front tire wake is essential for aero efficiency. A great study of this can be found below racecar-engineering.com/articles/wheel…

#F1Tech
There are three primary turbulent structures around a rotating wheel. From the referenced study, the influence of the front wing can not be ignored, so the results presented are generally present but can be different as teams design the front wings differently. #F1Tech
