Sauber started early on 2019 car - Vasseur
Sauber looked to prepare for aerodynamic changes in 2019 by starting work on their car "quite early", according to Frederic Vasseur.
The Swiss-based outfit's team principal made the admission following a relatively successful 2018 season as they finished eighth in the constructors' standings ahead of Toro Rosso and Williams.
The aim is to now kick on and move higher up the rankings ahead of more incoming car changes and to coincide with former world champion Kimi Raikkonen replacing Ferrari-bound driver Charles Leclerc.
"We pushed like hell quite early on next year's car. We switched all resources of the company on next year's car quite early," Vasseur told Autosport.
"We have good expectations but when you have a change like this in the regulations, it's a drastic one. You never know.
"You can take the wrong direction and we will understand this perhaps (only at testing) in Barcelona because nobody knows exactly what the others are doing.
"My feeling is very positive, that we are still improving week after week and with the same purpose we had (in 2018). I don't know if the others are doing a better job or not, but we are doing a good job."
