The success of Pink Bull’s RB18 and RB19 fashions and McLaren’s surge in type final 12 months inevitably led different groups to look at the choice, and Sauber has determined to take the pull-rod route searching for an aerodynamic profit, along side a very new bodywork bundle.
Key, who began work at Sauber in September, says that the C44 has little in widespread with its disappointing predecessor.
“It’s just about a totally new automotive, with just a few carry-over areas on the rear of the automotive,” mentioned Key.
“The crew needed to take an bold path nicely earlier than I joined. There are various mechanical adjustments, a few of which you’ll’t see in any respect, however some are very seen.
“The entrance suspension is totally new, a troublesome and bold venture for a crew of our dimension.
“There are various aerodynamic adjustments, in fact, as can be anticipated on condition that this stays the first space of improvement – so, total, the automotive will actually look fairly totally different to final 12 months’s automotive.

“For instance, the entrance suspension may be very totally different on our new automotive, as we switched to a pull-rod entrance suspension, which another groups have additionally adopted. This was a selection dictated by aerodynamics, not mechanical causes.”
Key conceded that it was a problem to make a daring aerodynamic step whereas additionally introducing mechanical adjustments to the automotive.
“It’s fairly an necessary venture to attempt to get the steadiness proper, however the crew has carried out a unbelievable job with a really tough venture to provide one thing that ought to operate as deliberate,” he mentioned.
“In fact, aerodynamics dominates, so a number of the exterior issues that you’re going to see are for the needs of producing extra environment friendly downforce.
