( CNN ) -- Lewis Hamilton is confident the return of the kinetic energy recovery system ( KERS ) to McLaren cars for the 2011 Formula One season will give the team a big advantage over their rivals . The system -- which stores up energy created when a car brakes to enhance the vehicle 's acceleration -- was first used in the sport in 2009 , and teams such McLaren and Ferrari used it to great effect . The technology was banned in 2010 as a cost-cutting measure , however , the device will return to F1 next year after a more affordable solution was found and 2008 champion Hamilton believes McLaren 's version is the finest on the grid . `` Our KERS is the best . It shud [ should ] deliver , '' the 25-year-old wrote on his Twitter blog Tuesday . Hamilton 's teammate and compatriot Jenson Button also hoped the energy-saving modification could help the team to get the better of Ferrari and 2010 constructors ' title winners Red Bull . `` I 've never driven with KERS before , but this team used KERS last year and used it well , I know because they kept coming by me at the start ! '' the former Brawn GP driver said during a McLaren web chat . `` They have so much experience in that area that I think we 'll have an advantage - as will Mercedes and Force India , who use Mercedes engines . `` We 'll have an advantage on Red Bull and Ferrari I think , which is great . We 'll take every advantage we possibly can . '' McLaren finished the season second in the constructors ' standings , 44 points behind first-placed Red Bull with Ferrari in third place . Red Bull 's Sebastian Vettel won the championship with British pair Hamilton and Button in fourth and fifth places in the standings . The 2011 season begins with Bahrain Grand Prix on March 13 and teams are already testing for the new campaign .
