Similar to the concept seen on McLaren's MP4-29, the Hinwil-based outfit's latest design features a 'finger' nose, although it has chosen to take a significantly different route with the positioning of the front wing pylons.

Moving further back, the car sports a pointed roll-hoop, while the rear wing mount is similar to the one seen on Ferrari's F14 T – an unsurprising outcome as the Italian marque supplies Sauber with engines and gearboxes.

"The radical changes to the technical regulations for 2014 mean that it's even harder than usual to make predictions for the new season," said Chief Designer Eric Gandelin. "We know what kind of package we've put together here, and we are happy with what we achieved, but it is difficult to foresee what shape our rivals are in.

"The earliest opportunity to gain an impression of where the teams are will come during testing. The path we have followed with the design of the C33 allows us maximum flexibility, so that we can react quickly. It is also clear that reliability will be an important factor. So this is an area which we have given very high priority."

Sauber will run the C33 for the first time at the upcoming Jerez test, which takes place from January 28-31.
