NOS Energy Drink is an energy drink sometimes distributed in a bottle designed to look like a NOS (Nitrous Oxide Systems) cartridge. It is produced by Monster Brands and licensed by Holley Performance, which owns the trademark. NOS is available in 8 and 16 ounce aluminum cans, 11 and 22 ounce resealable bottle forms and as a 2 ounce "Powershot." The original version is flavored with juice, but other variants including "fruit punch" and "grape" are also available. Like many other energy drinks, NOS contains high levels of taurine and caffeine, but differs in its inclusion of large amounts of L-Theanine.
The drink is named after a brand of nitrous oxide, a chemical additive used to boost the performance of cars during races and other events; it is very common to see the name featured on cars in their commercials. The site also sponsors a mini video section that features consumers doing stunts and other unconventional behaviors. A "Rate Your Ride" feature is also established for amateur and professional drivers to showcase their cars. Recently, NOS energy drink became the title sponsor for professional time attack and drag racer Chris Rado and Formula D professional drifter Chris Forsberg from 2008-2010, and also sponsored NASCAR driver Kyle Busch's #18 Toyota in the Top 3 series from 2008-2011. NOS has been sponsoring Ricky Stenhouse Jr. since 2012. NOS currently sponsors official MLG gamer Brett Doyle, who began his sponsorship in 2013.
