The start of the Formula 1 winter testing session has begun and 2010 constructor's champion Red Bull Racing chose the test venue in Valencia, Spain, to debut its 2011 contender--the RB7.
Calling the car's first on-track foray as special, technical director Adrian Newey aired the challenge the team had with incorporating the Kinetic Energy Recovery System (KERS) into the RB7.
"The big challenge for us this year was the reintroduction of the KERS system," Newey shared. "It's always a challenge to find solutions, which don't compromise the aerodynamics of the car. This season, with McLaren, Ferrari and Mercedes all having KERS, we need to get it to work, simply for performance off the line."
Team principal Christian Horner, on the other hand, relished the team's victory in securing both the driver's and constructor's championship.
"It’s a great feeling to arrive here and roll out the car with the number one on it as the reigning World Champions, but now the challenge is to keep it," Horner noted. "The team's been very focused on RB7 over the last few months; Adrian didn't release his drawings any earlier than normal, so the whole design group and production team have done a remarkable job to produce this car in the shortest possible time. It's a long season, the longest in F1 history, and we have some great opponents, but we are very motivated and will be working hard to hold on to the two world titles. I’m sure it's going to be a fascinating battle."
