Kimi Raikkonen has called on Lotus to keep trying and keep working after he took a strong second at the 2013 F1 German Grand Prix.

Raikkonen finished right on the gearbox of eventual winner, Sebastian Vettel and at the chequered flag the two were split by just 1 second.

Despite missing out on the victory though, the Finn was encouraged by the performance of the Enstone-based outfit and is hopeful the team can build on it going forward, although he did concede that the warmer temperatures had definitely given them a helping hand.

"We had a pretty good last stint of the race, but the cars are close on performance so it's difficult to overtake. Maybe some more laps would have helped us, but the race is only 60 laps so you have to do your best with that," Raikkonen reflected.

"After my first stop I was stuck behind a Mercedes for a while, but once I was past the car was pretty good.

"After the safety car three of us were able to pull away, but we were too close on speed to change the order.

"Of course, we wanted to win but today we didn't have the speed. [Overall] it was a good day for the team though - we are getting back to where we should be.

"The warmer temperatures definitely helped us [too], so let's hope for some more hot weather in Budapest."

Late on it looked like Raikkonen might only two-stop, however, in the end Lotus took the more cautious approach.

"We had a think about it, if we can try to run until the end, but we had a massive problem with the radio," Raikkonen explained. "I could hear them but they could only hear me between two corners. So I'm wondering now if we should have done it, take a gamble and try to go to the end because the tyres were pretty OK, my speed was pretty OK so it was hard to know what happens in the next ten laps. [But] we decided to come in and put the soft tyres [on].

"We then had good speed. Obviously I got some help from Romain [Grosjean - my team-mate] to get past [at the end] but that was... we would have had a big fight, anyhow. I could have probably passed him in a normal situation but obviously it would have cost me a lot of time and as a team we try to win.

"I caught up with Seb but, like I said before, we are too close on speeds and it's so difficult to overtake then. We tried everything that we had and failed to win but I think for the team we did a good race. Obviously I lost some more points to Seb in the championship. We [will] keep trying."
