Relentless

Relentless is sold in 500-ml cans and is marketed as being produced for "those with need of strong stimulation". The product's label includes a caution stating that Relentless is not suitable for children, pregnant women or those sensitive to caffeine.The can has a distinctive dark brown colouring, showing the muscles of a human's neck/head/shoulder area, and is marketed to provide continuing energy with the slogan of "No Half Measures" (a reference to the can size, which is twice that of a standard 250-ml can of Red Bull) but The Coca-Cola Company implies it refers to an encouragement not to settle for less than one's best. "Suffer for your art" is used on cans and continues to be included in advertising.

 

With the gradual release of new flavours, the original flavour was renamed "Origin".

 

Relentless was introduced to the New Zealand market in May 2008 by Coca-Cola Amatil. It is only available in a 440-ml can. In April 2009, CCA replaced the Relentless drink range with the Mother Energy Drink range with Inferno included, which is imported from Australia.

 

Each can used to contain an extract of poetry, taken from the works of poets including John Milton, Lord Byron, William Wordsworth, Edgar Allan Poe, William Ernest Henley, Albrecht Dürer and Percy Shelley.
