Mercedes explain why Hamilton struggled against Gasly

Mercedes have given an explanation as to why Lewis Hamilton struggled to overtake Pierre Gasly during the Emilia Romagna Grand Prix.

During a weekend to forget for the seven-time former World Champion, he spent a large portion of the race looking at the back of Gasly’s car seemingly unable to overtake him.

“Well, it’s the same problem we had in the sprint,” Shovlin responded when asked why Hamilton had struggled to overtake the AlphaTauri man. “When you are in what we call a DRS train.

“Now, the combined effect of the DRS at Imola plus the tow gives you around half a second of advantage against a car you are following.

“The issue is if that car is following another car and they themselves have DRS, almost all of that advantage is wiped out and that was principally the issue Lewis had.

“That because Gasly had DRS, they were following almost an identical speed profile down the straight. Lewis wasn’t really able to get alongside and that was why he spent the whole race rather frustratingly stuck in that position.”

As the Imola track began to dry, drivers were faced with a choice of when to stop to swap their intermediate tyres for slicks and Mercedes, led by Hamilton himself, were among the more conservative when deciding when to come in.

“If you look at the issues though as to
