After a disappointing season in 2014 without a single point, Sauber is hoping it can turn the tide this year. The team has two new drivers in Marcus Ericsson and Felipe Nasr, and the impact of the pair can already be seen in the sponsors showed in the C34. Another treatment for the new nose regulations this year is seen in the car, with a bulbous front nose section extending long and low to meet the requirements of the rules. The team said the changes to the nose have had a significant impact on the aerodynamic design of the rest of the car. The engineering team has focused on three main areas with the C34: performance in slow corners, weight reduction, and braking stability. "We were able to gain a lot of experience during the course of the 2014 season, which will have an influence on the Sauber C34," chief designer Eric Gandelin said. Parts will be added to the new car ahead of its race debut in Melbourne in mid March. "We will use the time up to Melbourne to ensure we're as competitive as possible when we line up on the grid for the season opener," Gandelin added. The Sauber will be powered by a Ferrari engine again, but the team said there had been significant chances to the architecture of the power unit for 2015. "In terms of its concept, the engine is very much comparable with last year's, but its architecture has changed significantly, necessitating numerous adjustments to the chassis", they added.
