Sauber reveals new-look 2015 F1 car

On the back of a disappointing 2014 F1 campaign, where it failed to score a single world championship point, the Swiss-based outfit is hoping it can rediscover the form that had it fighting for podiums in previous seasons.

Sauber has opted for a bold new look for the season ahead, with its colour scheme switching from white and grey to blue and yellow.

The Ferrari-powered car also has a striking nose design - featuring a more rounded front edge than seen on the other 2015 cars so far.

Sauber's design team has focused on three areas for improvement over last year's car: better performance in slow-speed corners, weight reduction and improved braking stability.

The car features slimmer sidepods compared to the C33, and the team has overhauled its radiator concept and now mounted them horizontally.

Packaging around the rear of the car is much tighter, and Sauber's quest to get under the weight limit to allow maximum ballast has been boosted by the raising of F1's minimum weight limit to 702kg.

The team also has an all-new driver line-up for 2015, as Marcus Ericsson joins F1 rookie Felipe Nasr in place of Adrian Sutil and Esteban Gutierrez.

Ericsson will be the first man to drive the car when he takes to the track at Jerez on Sunday.

Sauber plans to use an interim version of the car for the first test, which will include some parts still from the C33. These will be replaced with bespoke 2015 components ahead of the season.
