Sauber have confirmed they will experiment with a passive drag reduction system during pre-season testing.
Whilst the double-DRS system used by Mercedes last season has been banned, a passive system which stalls the rear-wing at high-speed remains legal.
Lotus experimented with the ‘device’ – as they called it – during practice last season and have worked over the winter to perfect it.
Sauber’s chief designer Matt Morris confirmed they too would look at such a solution.
“Passive DRS is allowed, so this is an area that we’re looking at developing through the course of winter testing,” he said at the launch of their new C32.
Morris continued to explain other areas they’ve been working on.
“We have a whole new braking system that we were developing last year,” he added.
“In terms of the chassis, this is an area we’ve spent a lot of time and effort on to save weight. We’ve made some savings without compromising safety.
“The exhaust is not massively different to what we finished with last year, we just further enhanced it.”
One of the most noticeable differences between the C31 and it’s evolutionary successor is the dramatically reduced sidepods – almost 50 per cent smaller – which Morris explained were a result of Sergio Perez’s Monaco accident in 2011.
“Checo had quite a bad accident in Monaco a few years ago and when we got the car back and we saw the sidepod all squashed in, we thought ‘I wonder if we could do that?’
“The sidepods are a bold move, a bold design, but we are pretty confident.”
