Auxtail – OEM Integrated Accessories

Auxtail offers OEM integrated, dealer fit, range preserving accessories for electric vehicles.

 

Customisation offers a new way to stand out from the Electric Vehicle crowd.

The Auxtail system is fitted at the dealership in the same way as a towbar. Homologation is not required.

Hiding behind the rear bumper is a folding mechanism that offers personalisation opportunities, including

      • 2 E-Bike carrying

      • Extendable to carry 4 mechanical bikes

      • Wide and low Cargobox maintaining rear access

      • A deployable Step

      • Active Rear diffuser for range enhancement and rear lift reduction

 

Auxtail have demonstrated the system can be deployed across different vehicle platforms, both Tesla and BMW.

Auxtail won the Hyundai EV Camper challenge in April 2026.

 

Why Integrate?

It saves time with no rack to fit

But isn’t any longer or taller when space is tight

Keep the aesthetics of original vehicle

Towbars were originally fixed, then they were removable, now often, once removed, there is no visible attachment. The latest can retract without detaching, and the most premium are deployed and retracted with a switch.

Integration is desirable and useful

Range Anxiety?

With electric cars aerodynamics is responsible for about half the range. Roof loads can cut range 20%. Towing can half it.

Putting a cargobox at the rear often increases range.  This is a partial diffusion effect.

An active rear diffuser offers greater benefits with integration to the vehicle where the lower surface extends at high speeds: like an active rear spoiler.  This diffusion reduces rear lift too.

 

Why Auxtail?

As strong as the vehicle.

Fixed to the chassis at towbar mounting points.

Designed in safety; Redundancy is built-in. 2 load paths throughout

We can facilitate quick, high quality vehicle integration, safety and optimal performance. We have OEM engineering experience.

In the electric era, it is harder than ever to differentiate. One well worn path is customisation.
