SAKHIR, Bahrain - Reigning world champion Max Verstappen sent a signal of intent to his rivals on the final day of preseason testing by setting the fastest lap time of the week by over half a second.
Red Bull brought a significant upgrade package to its RB18 car for the final day of the test on Saturday, and in the evening Verstappen started to explore its potential.
As the sun set over the Bahrain International Circuit, the Dutch driver upped his pace incrementally as he cycled through Pirelli's softest tyre compounds, lowering his lap time to a 1:31.
