The team's on-track success has been played out against a backdrop of financial upheaval, with owner Genie Capital having terminated a lucrative longterm sponsorship deal with Group Lotus -- owned by the Malaysian car manufacturer Proton.
The UK-based outfit will, however, continue to race under one of the most famous names in motorsport.

Team principal Eric Boullier insists that there are sufficient sponsorship deals to plug the monetary gap created by Group Lotus' departure.
"We have not lost our title sponsor -- not in the real sense of the word lost. We have decided to end the contract
, or the agreement, we had with them at the middle of last year," Boullier told the official F1 website.
"We wanted to change our strategy, and actually we are, if I may say so, wealthier than we were before. We have bigger budgets this year and will keep the name Lotus under a license agreement.
"We have signed some big names as sponsors. If you look at my shirt, there are two new names on it. We have been able to sign deals with Unilever and Microsoft, which are two really big names."
Boullier said the Bahrain race was a fitting tribute to the work put in by the team -- who previously competed under the Renault name.

"It was a fantastic reward. We haven't performed in that mode since 2006," he said.
"The fact is we were expecting to deliver something after the first three races, but we had to come to terms with the little glitches we had. When that was done -- voila -- it finally worked."
Boullier said there was a good relationship building between experienced former Ferrari driver Raikkonen, who is is in his 10th F1 campaign, and Frenchman Grosjean -- a 26-year-old who has yet to complete a full season.
