Christian Horner says 2014 one of Red Bull’s best F1 seasons.

Red Bull team principal Christian Horner believes that the 2014 is one of the best FI seasons for his team and Red Bull’s recovery from such a tough start to 2014 has been one of the team’s biggest achievements. Red bull really struggled during the pre-testing but the team fought back strongly and finished second in the construction championship after Mercedes.

“I think it’s been the most challenging year,” Horner said. “As a team, if you look back over the last six years I think it’s actually been one of our biggest achievements to come back from where we were pre-season. 

“Almost having done no mileage whatsoever, to be at the end of the season second in the world championship, to be the only team to have beaten Mercedes, to have won three Grand’s Prix and have however many podiums as we’ve had I think has been – considering where we started and our horsepower handicap – an enormous achievement by the entire team.”

And Horner said Red Bull never seriously considered changing power unit supplier despite the tough start to the season with Renault.

Red Bull Racing is an Austrian Formula One racing team. It is one of two teams owned by beverage company Red Bull GmbH, along with Scuderia Toro Rosso. The Austrian team becomes the first one to won four successive constructors championship titles in 2010, 2011, 2012, and 2013.

The team has used Renault engines since 2007, and has a contract to do so until 2016.

After an Austrian Grand Prix with poor results, Red Bull’s boss Christian Horner described the performance of the Renault engine as “unacceptable.” In an interview with Servus TV he said that, “the big difference between Mercedes and Renault is that when a driver with a Mercedes engine pushes the overtake button his car goes faster. When our drivers, which have a Renault engine, push the button, the car stops!”
