Lotus to evaluate Double DRS before Spain

2013 Bahrain Grand PrixPosted on Author Keith Collantine

Romain Grosjean, Lotus, Shanghai, 2013Lotus say they will test their Double DRS after the Bahrain Grand Prix in time for the next race in Spain.

Technical director James Allison said they will conduct straight-line aero tests on the passive device, which enhances the DRS effect above certain speeds.

“We still have work to do with it,” said Allison. “We?ll be trialling the DDRS again between the first round of flyaways and the start of the European season when we have an opportunity to do some straight line testing.”

With just five days between the end of the Chinese Grand Prix and the beginning of practice in Bahrain, teams have limited time to bring upgrades. However Lotus will have some new parts to test this weekend:

“We won?t be bringing anything particularly revolutionary on top of the China upgrades, but we will trial a suspension modification ?ǣ internal rather than to the wishbones ?ǣ which is an evolution of something we ran to good effect during pre-season,” said Allison.

“You?re always trying to find the right compromise between the mechanical grip that the suspension?s articulation offers to the tyres and holding the aerodynamic platform at the optimum height from the road, and we believe this is a step forward in helping us achieve that.”

Allison added the configuration of the Bahrain circuit should play into Lotus’s hands this weekend: “There are things that are special about Bahrain which might make us more optimistic.”

“For example, it is one of the most aggressive tracks on the rear tyres and if we have a particular strength it does seem to be that when we get the car set up just right it does seem to use the tyres rather gently.

“Secondly, in Kimi in particular, we have a driver who is able to get the car to go quickly without really burdening the rear axle.”
