NOS Energy Drink Drops Grand Prix Guava With a Caffeine Boost

NOS Grand Prix Guava dropped in April 2026, and for a brand that rarely adds to its lineup, it's a real event. NOS has been sitting on the same core flavor roster for years -- Original, Zero Sugar, GT Grape -- so a new permanent addition is news on its own. Add in a caffeine bump over the Original, and this one is worth paying attention to.

The flavor goes tropical: guava with a peach twist. It's a departure from the citrus-forward profile NOS has always leaned on, and it lands on a full-sugar, 16 fl oz can. If you want the full breakdown on what NOS is and where it came from, the NOS Energy Drink product explainer covers the history, formula, and the broader lineup.

Racing driver Ricky Stenhouse Jr. was brought in as the face of the launch. NOS has deep motorsports roots, and the "Grand Prix" name leans right into that.

Tropical Guava-Peach, 16 fl oz

The flavor name telegraphs the profile pretty clearly: guava up front with a peach finish. NOS describes it as a "juicy sweet burst" from the guava with the peach enhancing the tropical angle. Early Amazon reviews back that up, with multiple buyers flagging that it's sweeter than the Original but not cloying, and that the flavor reads as genuinely tropical rather than synthetic.

The can sports a bright pink body with neon yellow accents and a checkered racing flag motif. It's a bolder visual than the classic NOS blue, which makes sense for a flavor this far outside the brand's usual lane.

Grand Prix Guava comes in 16 fl oz single cans and a 15-pack case. It's showing up in convenience stores and gas stations, which is exactly where NOS lives, and it's available on Amazon.

Quick Formula Check

Grand Prix Guava is not a simple flavor swap. The label shows a few real differences from NOS Original, the most significant being caffeine. The NOS Energy Drink explainer walks through the Original's 160mg formula in detail -- this new flavor steps that up to 200mg.

• Caffeine (200mg) - blocks the signal in your brain that makes you feel tired, keeping you alert and focused. That's 40mg more than NOS Original, which puts Grand Prix Guava closer to the upper end of mainstream energy drinks rather than the middle of the pack.
• Taurine - an amino acid included to support the caffeine stack and contribute to cardiovascular and muscle function. The label doesn't disclose the exact dose, which is standard for legacy energy drink formulas.
• Inositol - a naturally occurring compound that supports cellular signaling involved in mood and mental clarity. Dose not disclosed.
• Vitamins - Grand Prix Guava includes a more complete B-vitamin panel than NOS Original. The label shows Niacin (B3) at 250%DV, Vitamin B6 at 240%DV, Pantothenic Acid (B5) at 400%DV, and Vitamin B12 at 510%DV. B vitamins support energy metabolism and neurotransmitter production. None of this is unusual for the energy drink category, but the expanded panel is a genuine formula difference from the Original.
• Other ingredients - carbonated water, high fructose corn syrup (50g added sugars per can, 210 calories), citric acid, sodium citrate, natural and artificial flavors, sorbic acid and benzoic acid as preservatives, sucralose, ester gum, Red 40, Yellow 5, Yellow 6. Full sugar formula, not a clean-label product, and it's not trying to be.

One thing worth noting: the Original's guarana extract does not appear in Grand Prix Guava's ingredient list. The caffeine in this can appears to come from caffeine directly, not from a botanical source.

Where It Fits in the NOS Lineup

NOS Energy Drink keeps a short roster by design. Grand Prix Guava slots in alongside Original, Zero Sugar, and GT Grape as the brand's first real tropical entry. The caffeine difference between Grand Prix Guava (200mg) and NOS Original (160mg) is the clearest way to differentiate them. If you're used to the Original and want a little more push with a flavor change, this is the play.

• Grand Prix Guava (15 Cans: $27.99)
• GT Grape (15 Cans: $28.21)
• Original (15 Cans: $24.34)

Where to Get It

Grand Prix Guava is available at convenience stores and gas stations in the NOS distribution footprint, which is broad thanks to Monster's retail network. It's also on Amazon in single cans and 15-packs. The PricePlow-powered links on Bevlab will show current pricing and stock.

If you've been sleeping on NOS (or you forgot about them in the sea of other options), Grand Prix Guava is the most interesting version of the brand in years. The flavor is a genuine departure, the caffeine is up, and the B-vitamin complex got a real expansion. For NOS regulars, it's an easy grab.
