The 2015 season was a difficult one for French manufacturer Renault and Red Bull Racing.

It’s fair to say the two corporations had a fairly large falling out.

Red Bull Racing attempted to walk away from Renault and Renault considered walking away from Formula One altogether.

Fastforward several months and after failing to do a deal with either Mercedes or Ferrari, Red Bull Racing ended up going back to Renault for a new power-unit deal in 2016.

Renault meanwhile purchased Lotus and became a fully fledged manufacturer in Formula One once again.

It turned out to be a good move, Renault obviously improved their engines during 2016, enabling Red Bull Racing to overtake Ferrari in the Formula One constructors battle.

Renault meanwhile are going through a transitional period, but once the team is built back on solid foundations it looks like they could prove to be competitive once again.

The team stuck in the middle of all of this was Red Bull Racing’s sister team Toro Rosso.

The 2015 fall out meant that Toro Rosso, who had already ditched Renault for 2016, ended up racing the entire season with 2015 Ferrari engines.

They could enjoy no development through the season and it was tough on the sister team.

For 2017, Toro Rosso return to brand new power-units with Renault.

But they could go down the same path as Red Bull, in re-branding their engines [TAG Heuer] with a title sponsor.

‘We have the possibility to find a title sponsor to rebrand our 2017 engine, as Red Bull did last year, We’re in talks with a sponsor,’ Toro Rosso team boss Franz Tost told Gazzetta dello Sport [as quoted by].
