Lotus struggled in Australia
The struggling Lotus Formula 1 team has admitted it may have to wait until Spain to be competitive again.
The Enstone outfit was forced to sit out the opening pre-season test of the year due to early teething troubles with the E22.
After a disastrous Australian GP weekend that saw both Romain Grosjean and Pastor Maldonado retire, technical director Nick Chester told Autosport that a return to the form of 2013 may take time:
I'm certainly hoping for an improvement for Malaysia and then some more in Bahrain, although as they are back to back it is likely to be small steps.
It may well be Barcelona before we are in a more stable position and compete at the level we want to be at. One thing's for certain, we're not sitting back; we're pushing all the way with the focus on extracting the maximum from the E22.
Chester added that the team will be taking some upgrades to Malaysia to enhance the aerodynamic package:
We are still producing new bodywork and have some good upgrades coming for Malaysia in all areas around the car. We will keep pushing as hard as we can with the upgrade programme.
