The team has decided to abandon running in order to fully understand the problem with the chassis that manifested itself on chassis 2, which ran for the first time today.

This is despite chassis 1 completing the full Jerez test two weeks ago. The team said the problem requires modification to both chassis.

The car completed 1788 km of testing at Jerez, but the problem manifested itself at the higher-speed Barcelona configuration.

"Before we were due to fly chassis E20-01 out to Barcelona in replacement of chassis E20-02 - damaged this morning - we ran a series of simulations at the factory based on the data provided by our brief running on track today," said technical director James Allison.

"As a result, we were able to identify an area which requires some additional work. It will be more productive for us to carry out these modifications to both chassis at Enstone rather than send E20-01 out to this week's test. We'll put the right measures in place and we will be able to fix the problem before next week."

Team boss Eric Boullier added: "Not running this week has been a tough decision to take, but we feel that our choice is the right one. On the positive side, we have quickly identified the issue with the chassis and our design office has already devised a solution. We will be present at next week's test in Barcelona.

"We draw faith from the fact that the E20 was quick out of the box in Jerez and showed its reliability there. We have a lot of work ahead of us over the next week but everyone at Enstone is ready for this challenge."
