Lotus to debut new exhaust in Korea

Lotus confirms a new Coandã-effect exhaust for the E20 in Korea
Lotus has confirmed that it will debut its own Coandã-effect exhaust for the next round of the F1 season in Korea this weekend.

The team will become the latest to run the exhaust system having carried out evaluation of the design in its wind tunnel, where the system was trialled alongside the more traditional style system is has used so far.

On the back of that evaluation work, Lotus is now set to run the new style exhaust in Korea this weekend, with technical chief James Allison explaining the reasons behind the decision.

“We've been ploughing something of a lonely furrow on the circuit with our relatively straightforward, power-maximizing exhaust,” he said. “However, since well before the launch of the E20 and to the present day we've been carrying out parallel developments in our wind tunnel programme based around a Coandã effect exhaust. Once we saw the potential gain of the Coandã system surpass that of our current design it was clear that we needed to implement it, both for the benefit we could get in the last quarter of this season and also for learning experience it presents us for next year. We will run our first version of this style of exhaust in Korea.

“It is not as big a deal as the 2011 style blown exhausts [when it comes to making the change]. Last year it was quite challenging to ensure that the exhausts did not set fire to the car. The Coandã system is a little more indirect, and the jet has cooled a little before it impinges on the floor which makes things a little easier to manage. There's still a fair amount of rearrangement including new Coke panels, new exhausts, new exhaust exit panels, some fireproofing of the floor and so on. All told, it's a biggish change rather than an enormous one. It's also easier to swap to and fro for evaluation.”

However, while the team is set to debut the new exhaust, Allison also confirmed that the Double DRS tested on numerous occasions in Friday practice has now been dropped until the Young Driver Test in Abu Dhabi.

“We haven't had the happiest of introductions with the system,” he said. “It's been harder than I anticipated to make it switch effectively with only the limited opportunity afforded in Free Practice. We're going to take it away, have another think and most likely give it another go in the Abu Dhabi young drivers' test where we'll have more time to develop it in a systematic fashion.”
