Lucozade Energy, already the UK's No 1 energy drink, has surged to another sales landmark in its brand development - by claiming the No 2 spot in the 'drink now' soft drinks sector and moving ahead of Diet Coke.

How? In 2005, Lucozade Energy added more cash value to the category than any other brand - £10.5m more than Coca-Cola; Lucozade Energy accounted for 44% of all energy & sports drinks sold through independent retail outlets; and Lucozade Energy Orange is the biggest orange-flavoured drink on the market, at £13m bigger than Fanta Orange.
