Both the Infiniti Red Bull Racing and Scuderia Toro Rosso teams have made minor sponsorship announcements in the run-up to their official 2014 unveilings at Jerez next week.

RBR confirmed that its partnership with Casio is to be extended through the 2014 and 2015 seasons, continuing a relationship that first began in 2009.

Represented by its Edifice brand of men's metal analog watches, the Casio logo will again be present on the driver's racesuits, as well as on the team kit worn at races. The logo will also be displayed on the nose of this year's RB10 car and its 2015 successor, while the partnership will again see both parties collaborate on a number of special edition watches.

"We are delighted to announce the continuation of our relationship with Casio, who are one of our longest-standing partners, having first joined us in 2009," team principal Christian Horner said, "Since then, we have built up a close alliance, which is due to our mutual understanding of the exacting nature of the environments we operate in. Accuracy, attention to detail and reliability are core values of F1, Infiniti Red Bull Racing and Casio. We're very pleased that this partnership will continue until at least 2015."

Toro Rosso, meanwhile, has signed a sponsorship agreement with Sapinda Holding BV for the upcoming season.

A privately owned principal investment holding company, which focuses on investment opportunities across continental Europe, Asia and Africa, Sapinda manages a global portfolio of long-term holdings in selected sectors and industries, with current focus on agriculture, mining, oil & gas and technology. The company's logo will be visible on the drivers' and mechanics' racesuits and on the mirrors and front wing end plates of the cars.
