The development of the RB9 chassis was influenced by the competitive demands of the previous season. In January 2013, Chief Technical Officer Adrian Newey admitted that work on the RB9 had been put on hold during the second half of 2012. This delay was a strategic decision to allow the team to concentrate on the development of its predecessor, the RB8, to ensure the 2012 titles. The car was designed to meet the final year of the V8 engine regulations before the transition to turbocharged hybrid power units. Sebastian Vettel followed his personal tradition of naming his chassis, calling his RB9 "Hungry Heidi" after German model Heidi Klum.
The RB9 was powered by a Renault V8 naturally-aspirated engine. Its livery featured a combination of dark blue and purple, incorporating sponsorship from Infiniti, Rauch, Pepe Jeans, Casio, and Geox. Large Red Bull branding was prominent on the side pods, hood, nose, and wings.
In 2014, a specialized electric version of the RB9 was produced for pit stop training. This version utilized the nose of the subsequent RB10 and was designed to move easily forwards and backwards, allowing mechanics to increase the frequency of their practice operations.
The RB9 debuted at the 2013 Australian Grand Prix, where Vettel took pole position but finished third due to tyre degradation; Webber finished sixth following a KERS problem. The early season was marked by a controversial victory for Vettel in Malaysia, where he ignored a team order to remain behind Webber. Vettel secured further early-season wins in Bahrain, Canada, and Germany.
The mid-season saw mixed results, including a disappointing performance in Spain where neither driver reached the podium, and a gearbox failure for Vettel while leading the British Grand Prix on lap 41. However, following the summer break, the RB9 became dominant. From the Belgian Grand Prix to the season finale in Brazil, Vettel won nine consecutive races, setting a new record for the most consecutive wins in a single season. He clinched his fourth World Drivers' Championship at the Indian Grand Prix.
Mark Webber, who announced his retirement from Formula One during the British Grand Prix weekend, finished his final season with several podiums, including second-place finishes at Silverstone), Japan, Abu Dhabi, and Brazil.
The RB9 represents the conclusion of the naturally-aspirated V8 era of Formula One that began in 1989. Beyond its competitive life, the chassis was used for promotional events, including a 2014 exhibition where Daniel Ricciardo raced an RB9 against a Royal Australian Air Force F/A-18 Hornet. As the final championship-winning car of the Newey-designed V8 era at Red Bull, it remains the last Renault-powered vehicle to win a Formula One world title.
