The wait is finally over for Sauber as the team will introduce an upgraded package at this weekend's Belgian Grand Prix.
Sauber made a strong start to the 2015 season with Felipe Nasr and Marcus Ericsson scoring 16 points in the first six races, but they have slipped backwards as they picked up only one point in the next four outings.
Their woes were blamed on the lack of development of the C34, but that's about to change as the car will have some major upgrades, including more horsepower from its Ferrari engine, at Spa.
"The Belgian Grand Prix can be considered the opener of the second part of the season, in which the Sauber F1 team is looking forward to stronger performances thanks to a number of upgrades that will be progressively introduced," Giampaolo Dall’Ara, head of track engineering, said.
"At Spa both C34s will be fitted with more powerful Ferrari power units and track specific wings. The track is an all-round favourite and demands high-speed cornering performance and straight-line speed, hence aerodynamic efficiency and power output.
"Traction and braking, although, as usual, important, are second to stability and reactiveness, therefore rather specific set-ups are being worked out."
