Force India driver Nico Hulkenberg is expecting a rapid development rate as the 2014 season progresses.
Hulkenberg finished in sixth place in the season-opening Australian Grand Prix and believes the pecking order will change on a race-by-race basis in 2014.
"This year we'll see bigger jumps and changes in the pecking order during the season," he said.
"There are still some teams that need to sort out their issues and they will probably become stronger. All teams, including us, will have room for improvement and development is going to be very fast."
The German is anticipating this weekend's Malaysian Grand Prix to present a tougher challenge to the drivers than last week's race.
"Malaysia is going to be a tough challenge with totally different track characteristics and higher temperatures, which always leads to higher tyre degradation," he said.
"It should be a good test of the new cars because it’s much more open than Melbourne with a nice variation of high and low-speed corners, plus two long straights."
Hulkenberg is wary that overtaking could be tougher than in 2013.
"It's a bit slower because of the regulations and you feel the loss of downforce compared with 2013," Hulkenberg said of the performance of the 2014 cars.
"Overtaking also seemed to be quite difficult, unless you are following a car that is really struggling. For example, you could see that Fernando [Alonso] couldn’t really make a move on me."
