Mercedes will race DAS at the Australian Grand Prix with a team spokesperson saying it would be “unreasonable” to give up that advantage just because Red Bull are threatening to protest.
Mercedes debuted DAS – dual axis steering – during pre-season testing at the Circuit de Catalunya.
The system, which changes the toe of the front wheels, is dictated by the driver pushing or pulling on the steering wheel.
It is thought that DAS not only improves cornering but also helps with speed down the straights and negates tyre wear.
Mercedes insisted from the get-go that is legal.
Rivals, most notably Red Bull, are adamant it is not.
Red Bull advisor Helmut Marko has threatened to protest should Mercedes race DAS at the Australian Grand Prix.
“For us, the system does not comply with the rules,” Marko told F1-insider.com.
“So we will protest when Mercedes uses the system in Melbourne.”
Mercedes, though, are not cowering.
A team spokesperson says Lewis Hamilton and Valtteri Bottas will use the system in Melbourne as the Brackley squad is not prepared to give up that advantage because of the threat of a protest.
“The season has only just started, and however small the advantage is, it’s unreasonable to give up every advantage we could have over Red Bull and Ferrari,” the spokesperson told Auto Motor und Sport.
“That’s why we will carry on using the DAS-system in our car at the risk of the protest.”
The Australian GP weekend begins on Friday at 1am GMT with first practice.
