Ferrari racer Fernando Alonso says that drivers will have to be clever in 2014 in order to reach the end of races.
The Spaniard, entering his fifth season with Ferrari, believes that the sport will be very different to last year.
“The new Formula 1 rules are very different to what we were used to,” he said.
“I think the concept of what constitutes a Grand Prix will actually change this year, with Saturday and Sunday being very different from one another.”
“In qualifying, one will be able to get everything out of the car, pushing the new power unit to the limit, trying to get the absolutely best result,” he added.
