That is a response to a new requirement for lower nose tips for safety, but teams' desire for the best airflow under the car for aerodynamic reasons.
Toro Rosso's drivers are France's Jean-Eric Vergne and
Russian Daniil Kvyat.
While F1 cars had grown to look increasingly similar to each other in recent years, the new rules have led to a number of different solutions to governing body the FIA's attempt to increase safety in 2014.
A complicated set of requirements define the chassis height at certain points, and the height and minimum dimensions of the nose tip.
Completing the biggest set of rule changes for a generation, F1 is moving to 1.6-litre V6 turbo engines with the most extensive use of energy recovery systems - or hybrid technology - ever.
Toro Rosso have switched from Ferrari power to Renault for 2014, bringing them into line with senior team Red Bull.
