Haas Formula 1 team boss Gunther Steiner has responded to title sponsor Rich Energy’s announcement on Twitter it has terminated its contract with the American outfit.

The energy drinks company took to social media on Wednesday to cite Haas’ “poor performance” for its decision to end its sponsorship deal just halfway into the 2019 season.

The full statement read: “Today @rich_energy terminated our contract with @HaasF1Team for poor performance. We aim to beat @redbullracing & being behind @WilliamsRacing in Austria is unacceptable. The politics and PC attitude in @F1 is also inhibiting our business. We wish the team well.”

Rich Energy, who signed as Haas’ title sponsor in October last year, has been in the midst of a court battle with British company Whyte Bikes.

The latter argued Rich Energy’s stag logo carried a resemblance to its own breaching copyright infringements, with the court ordering them to remove its logo after July 18.

Haas issued a statement on Thursday morning from Steiner, stating: “Rich Energy is currently the title partner of Haas F1 Team. I cannot comment further on the contractual relationship between our two parties due to commercial confidentiality.”

Despite the contract termination claims, the team’s motorhome in the paddock for this weekend’s British Grand Prix continues to bear the Rich Energy logos.
