Last in line, Toro Rosso unveils STR13

Toro Rosso completed the presentations of Formula 1’s class of 2018, unveiling its Honda-powered STR13 in the Barcelona pitlane.

The car will take to the track this morning in the capable hands of Brendon Hartley, with team mate Pierre Gasly taking over duties tomorrow.

The Faenza-based squad has gone for a livery which appears similar to what it ran on lasy year’s car, but the big change – and question mark – is the presence at the back of the beleaguered Honda engine.

The Japanese manufacture is expected to have made some solid progress over the winter but has it found the right power and reliability balance? Wait and see…
