ATL manufactures its ‘F1’ Style fuel cells using unique duPont Kevlar fibres that are tightly woven and then impregnated and coated using a revolutionary advanced elastomer.
With its unparalleled durability and superior strength, Kevlar remains to be one of the lightest materials used within racing cars. Whilst this incredible weight saving is an added benefit, even more important is the exceptional flexibility that the FT5 fuel cells offer. Their pliable nature allows ease of installation and removal through relatively
small monocoque apertures.
FIA approved for Formula One, World Series by Renault, A1GP and Formula Nippon

For over 20 years, ATL has produced racing fuel cells for EVERY F1 team.
The construction of a modern F1 cell is very complex and requires many man hours of work to complete.
Every Cell is custom manufactured from ATL 818-D Lightweight and features wide-overlap seams and double reinforced nut ring apertures and corners. Alloy or carbon composite nut rings and fittings fused onto the inner panels provide strong, leak-tight attachment points.
In the past fuel strategy has played a very important role in every Grand Prix, with fuel levels often running very low.
ATL fabricate and install complex internal baffle systems, using alternative lightweight fabrics, to ensure a constant supply of fuel to the engine. With no refuelling in 2010, the baffle systems play a equally important role, helping to stop fuel slosh, yet at the same time optimising fuel scavange to ensure that the cars need carry no more fuel than absolutely necessary.
ATL’s thin wall construction and precision geometric fit help maximise fuel volume as well. Our unique construction techniques also enable us to modify existing fuel cells, as well as install Fuel Pump Mounts, Trap Doors, Hose Mounts and Monocoque Breakaway Pins. |

In addition to F1 ATL can also supply FT5-1999 cells for other single seater cars such as Formula Nippon and A1GP chassis. Our construction methods allow us to integrate features such as fabric, alloy or composite internal collector systems and baffles to aid fuel pick-up.
