Honda and McLaren are expected to formally split this weekend after the Singapore Grand Prix, and that might not be the only Formula One split of the weekend.
According to The Drive, Red Bull could be parting ways with Renault and partnering with Honda once Honda splits with McLaren. Red Bull Racing consultant Helmut Marko wants to make the switch to Honda as long as Honda makes the proper upgrades.
Red Bull and Renault are expected to end their relationship after 2018.

The story also says STR and McLaren are planning to trade engine suppliers after the 2017 season. STR is using Honda's power units from 2018 through 2020.
If Red Bull doesn't go with Honda, the story suggests they could also try to strike a deal with Porsche in a few years since Porsche is aiming to have a Formula One engine.
Those are several major shakeups for the sport, and the McLaren and Honda split opens up several potential partnerships over the next few years in Formula One.
Red Bull will likely test things out with Honda before officially moving on to them, but they clearly aren't pleased with Renault.
