Toto Wolff has downplayed speculation that DAS has handed Mercedes the World titles, saying it is not worth the lap time that some are suggesting.
Mercedes debuted DAS in pre-season testing, caught using the system by eagle-eyed fans.
DAS is activated by pushing and pulling on the steering wheel, which changes the toe of the front wheels.
Changing the toe not only helps with drag down the straights but also improves cornering and reduces tyre wear.
DAS, which stands for Dual Axis Steering, is new to Formula 1 this season with Mercedes adamant it is legal.
However, only for this year as already rules are in place banning it from 2021.
In the meantime, though, Mercedes reportedly have an advantage that could be worth tenths per lap, if not even more.
Wolff has rubbished claims that it is worth over a second per lap.
“We don’t want to reveal too much about it yet, but whoever thinks it will give us two seconds is wrong,” Grandpx.news quotes him as having told Bild am Sonntag newspaper.
“It is one of many innovations on the new car.
“Ultimately, it is the overall package that is crucial.”
Valtteri Bottas, who set the pace in pre-season testing, believes Mercedes will have DAS available when they take to the Albert Park circuit for the season-opening Australian GP.
“We’re happy to have it on the car, and now it all goes pretty smoothly and starts to feel like everything goes pretty automatically without too much thinking about it, and we’re using it what we think is the best,” he said.
