Red Bull's Ricciardo shines in practice

Given that Ferrari and Mercedes have previously rejected Red Bull's requests for engines, Honda appear the likeliest of F1's four current makers to be the team's power providers in the season after next.

Red Bull's Daniel Ricciardo and Max Verstappen topped free practice for the Singapore Grand Prix on Friday, as McLaren's move to dump engine supplier Honda triggered a wave of upheaval off the track.

Both Porsche and Aston Martin, a long-time affiliate of Red Bull, are thought to be interested in joining F1 depending on the outcome of the sport's proposed engine revamp for 2021.

McLaren will be powered next year by Renault, which simultaneously said it was leaving Toro Rosso - who will now be driving Honda engines.

The BBC, Sky Sports, Daily Mail and the Autosport.com website all reported that Renault was going to split with Red Bull after 2018, without naming sources.

The Briton, who seized the overall lead from Sebastian Vettel after leading Bottas to a one-two finish in Monza, is expecting a less straightforward weekend in Singapore. "Next year will be a Tag-Heuer-branded Renault".

"We just want to be in a competitive position so I think these hybrid regulations have been quite frustrating in many, many respects", Horner said.

In a sport where winning is determined by the machine as much as the man, the only true level playing field is between team-mates who drive the same car.

Tomorrow's race in the city-state would otherwise have been the last. The two were able to secure four consecutive driver's championships and constructor's titles from 2010 to 2013.

The Australian driver, who has been dubbed one of the most talented drivers in the world, will come out of contract at the end of 2017 and has threatened to walk away from the Red Bull team if it signs a deal to use Honda powertrains. "I think we've got to keep that going to Abu Dhabi and then make another step across the (northern) winter to start strong for 2018".

"Verstappen publicly apologised to Ricciardo after knocking him out of the race with a poor passing move, with the Aussie later branding his teammate a 'f--ing sore loser". Then they used a chair and a squeaky chicken before resorting to throwing it on the floor. Calvin Harris, Ariana Grande and Seal are on the bill this year. It has also contributed S$1.4bn in tourism receipts to Singapore over the past decade and drawn over 450,000 international visitors, including projected arrivals for this year's race. "Everybody's agreement in F1 goes up to the end of 2020".
