Lotus expecting major improvement

Monday 05-May-2014 09:57

Lotus will bring its first major upgrade of the season to this week's Spanish Grand Prix, Technical Director Nick Chester confirmed.

Many teams are expecting to bring upgrades to the Circuit de Catalunya this week, but Chester hopes that the Enstone team will finally get the opportunity to illustrate the capabilities of their E22 in Barcelona.

"We had a huge amount to get through [in China] because we hadn't run much in the Bahrain test," he explained when asked about their expectations for this week by

"We assessed over half of the new parts, which is a positive, and we have a lot more lined up for Barcelona.

"We've got further improvements on engine mapping, which should give us another step forward.

"We've got a new cooling and bodywork package coming - quite a big upgrade - plus some updates to the rear wing and various other bodywork parts. All of the developments that we've brought for the car so far have been an improvement, which is highly satisfying and validates the hard work being done back at the factory.

"We also received more horsepower from Renault Sport F1 in China and I hope we'll get a further step-up in Barcelona, which will make a massive difference.

"There are a lot of aero improvements we want to bring to make the car more predictable for the drivers.

"We also want to do more work on tyre temperatures. The latest generation of tyres are quite hard in compound and it can be difficult to keep them in the optimum operating window.

"The E21 was very kind on tyres as we know, but we are still really discovering the E22, so it is difficult to know for sure [how they will react]. What is certain is the fact that the left fronts at Barcelona will be key because of the long constant radius turn three.

"On the other hand, braking is definitely better now. We've made some good improvements in terms of how the drivers can control the brakes and manage the power unit during braking. Power is always important, but it plays a smaller role than at other circuits so we are expecting to be reasonably competitive at both [Barcelona and Monaco]."
