Lucas di Grassi has said that F1 champions Sebastian Vettel and Lewis Hamilton would find it tough in Formula E.

In an interview with CNN ahead of this weekend’s Paris Formula E race, the ABT driver and current Formula E championship leader said: “They would have a hard time coming to Formula E…They are fantastic drivers, they are the most talented drivers of our generation and maybe, I would say, almost our lifetime, but if they come to Formula E they would find it hard. They will have to learn the tracks, because all the tracks are brand-new, they are all city tracks, you cannot practise on the tracks. Because you cannot close Paris and say ‘Okay, I want to practise’.”

The Brazilian racer went a step further, saying: “I think I will invite them to come to race, even if it’s just one race, and see how it is. I’m sure they would be tough competition, but they would have a hard time.”

Boys, the gauntlet has been thrown down.
