Lotus back on track after chassis issues

Lotus say they have resolved the chassis problem - confirmed as an issue with the mounting of the upper front wishbone rear arm - that caused them to abandon last week's second pre-season test in Spain after only a handful of laps. The team were using their second E20 car for the first time and after driver Romain Grosjean reported a problem their initial suspicion was a manufacturing fault specific to that chassis. However, subsequent investigations showed that changes were required to both chassis.
