Relentless is the brand name of an energy drink created in February 2006 by The Coca-Cola Company. It has been compared to energy drinks such as Red Bull. The drink has also been the subject of court proceedings for breach of trademark by Relentless Records. In the year ending 2010, sales of the product in the UK increased by 28 percent.
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.

In August 2007, Coca Cola announced a new variety – "Relentless Inferno". This contains the same amount of energy and caffeine as the original Relentless, but it has a mixed orange flavour to it, giving a similar taste to other orange soda/soft drinks on the market.
In the UK Relentless Inferno was introduced for free in the Relentless Tents at the Leeds and Reading Festivals in 2007, upon entry to the tent everyone received one free can of the new flavour Relentless.
With the release of Apple & Kiwi, Inferno has been renamed "Orange". In August 2013 it was renamed "Orange Crush" stating a new refreshing flavour. However, many people complained about the new flavour.

In 2011, with the rebanding at the time, it was renamed Immortus. With the release of Apple & Kiwi, Immortus has been renamed "Tropical Juiced". The recipe has also changed, giving it a "new refreshing flavour", but also reducing the juice content to 20%.
In the first quarter of 2009, the second flavour was added to the Juiced Energy series, with the new addition being named Juiced: Berry. Contrary to the yellow colour of Juiced: Tropical, Juiced: Berry has a dark red/purple colour, and its can is the same colour. The flavour consists of strawberry, raspberry and blackcurrant, and again features the "50% juice 100% energy" slogan and contains the same amount of taurine and caffeine as all other the versions.
The slogan behind the Berry flavour is "Relentless Berry, Brave each new dawn."
Marketing for these versions are targeted towards the drinker using the drink to wake up; it was introduced as a market response to a survey in which 97% of people responded that they need energy, but that only 30% buy energy drinks.
In 2011, with the rebanding at the time, it was renamed Devotion. With the release of Apple & Kiwi, Devotion has been renamed "Berry Juiced".
January 2011 saw the release of a sugar-free version of the drink that was sold alongside the other five varieties already available, to target consumers who desire energy without the sugar content. It is sold in a blue can and has a similar taste to the original version of Relentless, although it still has the same amount of caffeine and B vitamins.
In its initial release, it was named Libertus. With the release of Apple & Kiwi, Libertus has been renamed "Sugar Free".
