Red Bull financial costs 'enormous' due to 2017 rules

2017's rule changes increased Red Bull Racing's spending "significantly" according to their team principal, Christian Horner.

Red Bull's accounts for 2017 state that their spending increased from £193.0m in 2016 to £226.7m the next year - indicating a rise of 17.4%.

"It's as simple as that, the cost of change in F1 is enormous," Horner explained to Autosport. "You can see it will have an impact on all the teams. When you scrap a concept of regulations and have a change of size that we had, it's significant."

Red Bull's turnover rose from £197.9m to £231.3m in the space of a year. Red Bull parent company helped the team to top up sponsorship from the outside and the F1 prize money.

The parent company figure given rose from £40.6m to £56.5m, with Red Bull ending their world championship victories, the less prize money they were receiving - meaning they were more reliant on the parent company to help them with some costs.

"F1 still represents strong value for the brand," Horner continued. "It's the biggest marketing activitity within the Red Bull Group. F1 has a global audience and reach. Obviously its digital audience is increasingly rapidly as well.
