Sebastien Buemi and Nelson Piquet Jr have revealed that Formula E is more testing than F1.

The all-electric series began four years ago and the two experienced drivers entered in the opening season and have had to adapt from behind the wheel.

An aspect of Formula E which makes it so unique is that practice, qualifying and the race are all rolled into one day.

This adds immense pressure on drivers who are used to racing events which stretch over at least three or four days.

But it provides non-stop action for spectators and it gives teams and drivers minimal time to rest.

It means if there is a problem in one of the sessions prior to the race, they have very little time to react, which has a knock-on effect throughout the day.

Jaguar’s Piquet Jr said: “It’s tough, when I go back to doing normal weekends, you have so much off time it’s crazy.

“You fall asleep during the day, wake up, have a nap, talk, do something, go back, have another nap.

“You eat a lot, you end up gaining weight during the day. Over here in Formula E you hardly have time to breathe.

“I would prefer probably a two-day event, but it’s the same for everybody so I am not going to complain.”

Buemi also gave an insight from behind the wheel into what it’s like driving a Formula E car compared to an F1 car.

He said: “The cars are much more similar than what people would expect it to be.

“In a way it’s easier because you have no gears, it’s just a throttle and the breaks but what makes it difficult at the moment is the fact that the battery is very heavy.

"It’s at the back of the car so the handling is very difficult to manage.

“You need a lot of skill to manage the car on these street tracks and of course you need massive skills in F1 as well but it’s kind of different skills you need here.”

Both drivers have a Formula E title to their name and only seven points separate fourth-placed Buemi and Piquet Jr in fifth ahead of the E-Prix on the beach in Punta, Uruguay, on Saturday.
