Lotus expecting further boost from Coanda exhaust in India

Lotus technical director James Allison Lotus technical director James Allison says the team's Coanda style has been a good boost and is convinced there is more to come from it.

The team raced the system in the Korean Grand Prix, where Kimi Raikkonen made good use of it to finish in fifth position.

Both Raikkonen and team-mate Romain Grosjean will race the system in India this weekend, and Allison expects the team to make more progress with it.

"We were reasonably pleased with how it performed on its first outing," said Allison.

"We knew that our first implementation would be a little power hungry, but we hoped for - and were delighted to register on the track a good downforce boost.

"Our initial design was already a step forward relative to the previous system, but we expect more from this package as we modify the exhaust to recover much of the lost power."

Although Lotus was unable to fight for the podium positions in Korea, Allison reckons its form was stronger than in previous races.

"We didn't set the world alight, but we got both cars home in the points and were notably more competitive than in recent races in terms of the gap to pole position," he said.

"Furthermore, over the course of the weekend we managed a successful implementation of our Coanda exhaust system as well as reacting to a front tyre graining issue that is a feature of the Korean circuit."

Allison confirmed that this weekend both drivers will be able to use a new front wing only run by Grosjean in Korea.
