Pirelli reveal rainbow of tyres for 2018

The 2017 season has barely been over a week and Sauber are already motoring ahead with their plans for next year, hosting a livery launch in Milan that announced their driver lineup for 2018 as well as showed off a significantly revised colour scheme.

Valtteri Bottas converted his pole position into a race victory relatively comfortably, in a final race of the season that was resoundedly disliked as being dull by almost everyone. Lewis Hamilton, who finished second so obviously has some grounds for dissatisfaction, said of Yas Marina: "It's a great, great track but unfortunately it doesn't suit the cars very well."

Valtteri Bottas was the fastest driver in Q3 on Saturday in Abu Dhabi, with the Finnish driver securing pole position for the final race of the season. Lewis Hamilton was just a tenth of a second behind him, leaving the Red Bull and Ferrari drivers to split the second and third row of the grids between them.

Ahead of the final race of 2017 in Abu Dhabi, Pirelli launched their lineup of tyres for the 2018 season, including two new compounds and extending the range from five to seven levels of hard and softness. The tyres are all one step softer than what we've seen this year, but there's a new superhard tyre that is orange. The hard tyre turns blue, or ice blue, as they call it.

After testing out a rotating selection of drivers for the past few race weekends, Toro Rosso have hit upon a pairing they like - the current form of Brendon Hartley and Pierre Gasly. The duo have been signed for 2018, with both set for their first full season in the sport.

Valtteri Bottas' pole position lasted only moments as Sebastian Vettel swept past the Mercedes to take the lead into the first corner. There was chaos in the opening laps, as Romain Grosjean picked up a puncture and punted himself and Ocon off track. Daniel Ricciardo spun, dropping him down the field, after he'd made a good start trying to recover from a low grid position.

Lewis Hamilton's qualifying session came to an abrupt and early end when he crashed heavily into the tyre barriers just four minutes into Q1. The red flags came out whilst the car and the driver were recovered - he was fine - and then the action continued. The two Saubers, Stroll and Gasly were out in that first session. Brendon Hartley got his Toro Rosso through to Q2 but didn't participate in that session.

Felipe Massa has talked of his disappointment and sadness that his home country has failed to deliver a safe environment for the F1 paddock to race in, after several high profile incidents for teams leaving the circuit. Lewis Hamilton revealed that part of the Mercedes crew were held up at gunpoint, with shots fired, in an armed robbery, with Williams and FIA officials also in the convoy of cars.

Toro Rosso have really been struggling over the last few races, suffering power unit problems that have cost them running time and more importantly race finishes. Both drivers are due to have grid penalties again this weekend, and it has sparked a war of words between Toro Rosso and their engine provider Renault.

Lewis Hamilton and Valtteri Bottas were in a class of their own during Friday practice in Brazil, battling each other for the top spot and leaving the rest of the field in their wake. Hamilton dominated both sessions in the end, but they finished the day just four hundredths of a second apart.
