Haas have one final upgrade for 2016

Haas have a single upgrade remaining for the 2016 season which will be rolled out at the Singapore Grand Prix weekend.

Team boss Guenther Steiner revealed, "We have a small upgrade package for Singapore, which will carry on the whole season obviously, so that will be something to judge in Singapore."

Haas had an upgraded Ferrari power unit for Italy,. but the track did not suit the American team, however Steiner insists there was a notable performance boost

"Absolutely it was a step forward. How much is difficult to say because we don't have any direct comparison. But it was a step forward – without that we wouldn't have made it into Q3."

Steiner explained why the team under performed at Monza, "I think it was track-related. Spa we were pretty good, Spa was better. Also Hockenhem we were already a little bit ahead. We need to see if we can continue this trend in the next races."

As for the unique characteristics of the night time street race at Marina Bay Circuit, Steiner said, "Singapore is a bit of a gamble anyway so we want to see if we can get it to work properly and then be ready for the races afterwards. But we hope the trend continues."
