Nico Hulkenberg believes that Formula 1 has never faced such uncertainty ahead of the start of the new season.
Hulkenberg returns to Force India this year and reckons that the rule changes – which include the introduction of 1.6 litre v6 power units – means that no-one can be sure of the pecking order ahead of the first test at Jerez in two weeks’ time.
“At the moment, nobody knows how this season and the new cars are going to be,” he said.
