My bet is their underbody is producing more downforce than the rest - they were running quite skinny rear wings as well so there's less geometry to pull the wake up. Just a guess (relatively educated) though.
The stewards reports are all published on the FIA website - so any investigation can be investigated. They were really busy at Silverstone!!LM10 wrote: ↑11 Jul 2018, 00:36Grosjean didn't just hit Sainz, but also Magnussen in the first lap. I must have missed it in the race and just saw it in the video with best onboards:

Hi hit and clearly put significant damage on his teammate's car. Is there even any difference between that crash and the one from Kimi in regards of how they happened? Both were inside and locked up into the car outside. I'm baffled that neither this nor the crash with Sainz was penalized by the stewards.
On the lap 1 incident they accepted Grosjean's excuse that he was taking evasive action from the Hamilton/Raikkonen incident ahead (seems a stretch to me but maybe the Haas team manager wasn't fighting for a penalty). In the Sainz/Grosjean incident they suggested that Sainz had put himself in a slightly dangerous position by overtaking on the outside - they said he closed the line a little but left enough room for Grosjean - but that contact happened because Grosjean lost front downforce from the aero wash from Sainz's front wing. Looks to me to be a reasonable read of the incident to me.
