The centrepiece of Sauber's new package for Singapore is a short nose, F1 correspondent Roger Benoit claims.
The struggling team has rarely updated its 2015 car this year but a major aerodynamic package will be raced by Felipe Nasr and Marcus Ericsson in Singapore this weekend (Sept 18-20).
New nose
Benoit, writing in the Blick newspaper, said the most obvious change will be the disappearance of the long "duckbill" nose, replaced by a shorter one.
Said Ericsson: "Our goal is to get the maximum out of this innovation."
