What does Norris need to do to catch and beat Verstappen?

Yes, but it is hard to predict reliably which ones.

Various cars have specific strengths. McLaren struggled relatively in Austin, they believe, because there were only a couple of corners at the end of the Esses that played to their strengths in medium-speed bends.

By contrast, the Circuit of the Americas has a lot of high-speed corners, and braking from high-speed into low-speed, and low-speed. The first two of these characteristics are strengths of Red Bull, the last Ferrari.

After their dominant wins in the US and Mexico, Ferrari now seem to be potential winners everywhere - although Qatar will probably be their worst circuit.

Qatar should be particularly strong for McLaren; Las Vegas favours Ferrari. Red Bull are always strong in Abu Dhabi, but they seem to have on balance the third-fastest car at the moment.

The cars are so close that other factors can come into play, too - who has a better weekend, driver performance etc.
