Force India's VJM07 has come "a long way" since the Jerez test, says a confident Nico Hulkenberg.
Entrusted with the car on the final day of pre-season testing, Hulkenberg claimed fourth place on the timesheets during his 74 laps.
And although it was a solid final day on paper, Hulkenberg revealed he did not do a race simulation on the day.
That, though, has done very little to dampen his confidence.
"The final day of testing went pretty wellm," he said.
"In the end we didn't do the race simulation, but we did some long runs and signed off a lot of other things on the job list.
"We didn't do as many laps as yesterday (Saturday), but we still made progress and learned some new things. So it's been two good days for me and I'm feeling pretty satisfied.
"You always want more time to prepare, but I think we're in good shape. The car has come a long way since the first Jerez test and we have made progress every day."
