Nico Hulkenberg has believes Force India have not shown their true potential yet this season because they have been marred by disruption in each of the races.
After ending the 2015 season in impressive fashion, the Silverstone-based team has failed to follow up on those results, something which Hulkenberg laments.
Ahead of this weekend's Spanish Grand Prix, the German driver also added that despite them having an encouraging pre-season testing at the Circuit de Barcelona-Catalunya, the team knows that it will be a different situation entirely.
"The things have gone against us for the last few races," the 28-year-old said.
"We know we should have scored more points, but it’s impossible to plan for the bad luck we’ve experienced. I’m looking forward to a weekend where everything goes to plan so that we can show our true potential.
"When you come back for the race everything is different: the cars have evolved, the temperatures are warmer, and you have to work hard to find the right set-up.
"That's why it’s a tricky circuit because confidence counts for a lot and, if you’re not totally comfortable, your lap times really suffer."
