Lotus poised to launch fightback at British GP with 'biggest step forward' of 2013

Lotus are expecting to make their "biggest step forward of the year" via the introduction of a significant package of upgrades onto their E21 car for the British Grand Prix.

Team boss Eric Boullier, meanwhile, remains confident that both Raikkonen and the team will continue to be major players in the championship battles and can demonstrate the E21's strengths again at Silverstone. "We've learnt some valuable lessons and drawn the line under the Canadian Grand Prix. We head to Silverstone with a determined strategy to be back fighting for podiums," the Frenchman insisted. "We're certainly not going to let two weekends of poor results stop us in our efforts. "We have a very reasonable package to fit to the E21 for Silverstone - with a number of elements which should help with our performance - and we have plenty of other upgrades to come later in the season too."
