Tesla Model S Carbon Fiber Full Long Tail Trunk

For Tesla Model S owners who want more than a simple add-on spoiler, this full carbon fiber long tail trunk is a complete rear-end transformation. Rather than attaching a spoiler to the factory hatch, this design takes the proven long tail shape and molds it directly into a one-piece trunk and hatch lid. The result is cleaner, more dramatic, and far more cohesive than a traditional stick-on or bolt-on rear spoiler.

The biggest visual difference is how integrated everything looks. Instead of a separate aerodynamic piece sitting on top of the hatch, the spoiler form is built into the trunk itself, giving the Model S a smoother and more intentional rear profile. It looks lower, longer, and more exotic from every angle. This same long tail design language is also used on our iconic Model S Plaid Dark Helmet Race Car, where it is paired with additional aerodynamic elements for even more extreme performance applications. On the Model S, it brings that same motorsport-inspired rear shape into a more refined and complete package.

This is not just about style. The long tail profile helps create more rear downforce and improves high-speed stability, making it a meaningful upgrade for drivers who want their Model S to feel more planted as speed rises. Because the aerodynamic shape is identical to the long tail spoiler, the performance benefit remains, but the execution is smoother and more advanced thanks to the fully integrated design.

Construction is a major part of what sets this product apart. Unlike cheaper aftermarket trunks that rely on carbon skin over fiberglass, this piece is built using autoclaved prepreg carbon fiber with Kevlar reinforcement. That matters. Autoclaved prepreg carbon is the standard for high-end motorsport and premium performance applications because it delivers better consistency, better strength, and better overall quality than vacuum-infused or wet carbon alternatives. The inside of the trunk shows that difference clearly. This is where the quality stands out, with a true full carbon inner structure that reflects the level of engineering and finish expected from a premium component.

Weight savings are another major benefit. Carbon fiber reinforced construction is significantly lighter than the factory aluminum panel, helping reduce weight high up and at the rear of the car. That supports both performance and efficiency while adding to the sharper, more purposeful feel of the vehicle.

Strength is just as important as weight. This trunk is built to be high strength, which also makes it a strong foundation for customers who want to mount an added racing wing and push rear downforce even further. For the Model S owner who wants lighter weight, stronger materials, more stability, and a far more aggressive rear design, this full carbon fiber long tail trunk delivers on all fronts.
