Paddy Lowe: engines to be ‘significantly’ louder in 2016

Formula 1’s modified exhaust regulations should lead to a “significant increase” in engine noise levels for the upcoming season, Mercedes technical chief Paddy Lowe has explained.

As part of plans to boost the spectacle, F1 chiefs last year mandated that the wastegate on cars must exit via a separate tailpipe from 2016, having previously been fed into one exhaust.

Although unsure of the exact results, Lowe is adamant the changes “will work”.

“In the last two years we’ve had a situation where the main exhaust goes through one tail pipe,” commented Lowe, when asked about the exhaust regulation changes.

“Then we have a thing called the wastegate, which is a way of spilling out any extra pressure from the exhaust system when it’s not wanted to be used by the turbo.

“[Under the new rules] we have to duct that air separately through an extra tailpipe, and this is all intended to make more noise, so we’re trying to make the engine louder.

“It will work, and we’ll see how much louder they’ll be. Some measurements have been made in labs and they’ve seen some significant increases [in engine noise levels].

“The reason for that is the wastegate was causing a sort of silencing of the main exhaust pipe, so by removing it from the main exhaust pipe we have less silencing going on.”

Shortly after the introduction of the V6 turbo units in 2014, Mercedes trialled a ‘megaphone’ exhaust as a potential noise solution, but the concept was not adopted.
