How to Choose the Right Towbar for Your Electric Vehicle

Quick Takeaways: EV Towing in 2026

• Type Approval: Not all electric vehicles (EVs) are legally approved for towing; check your V5C logbook (Section O.1) for the towing capacity before purchase.
• Noseweight (S-Value): EVs often offer higher noseweight limits than internal combustion engines, providing superior stability for caravans like the Bailey Alicanto.
• Dedicated Wiring: Non-negotiable for EVs to adjust regenerative braking, battery cooling, and safety systems when a trailer is detected.
• Towbar Choice: Detachable swan neck towbars are the gold standard to avoid interfering with aerodynamic under-trays and parking sensors.
• Range Impact: Whilst the towbar itself is negligible, towing a caravan can reduce EV range by 30-50% depending on aerodynamics and speed.

As we move through 2026, the presence of electric vehicles (EVs) on UK campsites is growing rapidly. For the modern caravanner, switching to an EV like the Tesla Model Y, Kia EV6, or BMW iX offers incredible instant torque and a serene towing experience. However, the hardware required to connect your caravan to your EV is more complex than a standard petrol or diesel car. Choosing the right towbar and, crucially, the right wiring, is vital for maintaining your vehicle's warranty and safety systems.

Is Your EV Approved to Tow?

The first step is checking the V5C logbook. Some early EVs, and many hybrids, were not 'type-approved' for towing. If the towing capacity (technical permissible maximum laden mass of the trailer) in your logbook is '0' or blank, you cannot legally fit a towbar for towing. You may, however, be able to fit a 'cycle-carrier' bar designed only for vertical loads. Use our Towing capacity by reg tool to verify this before booking an installation. Vehicles like the Hyundai IONIQ 5 and Volvo EX90 have healthy towing limits, but some base-model EVs do not.

Choosing the Towbar Type

For EVs, the 'Detachable Swan Neck' is the industry favourite. Because many EVs have aerodynamic under-trays and sophisticated rear parking sensors, a fixed towbar can interfere with the car's 'eyes'. A detachable bar allows you to remove the hitch entirely when not in use, keeping the car's look clean and ensuring the sensors work as intended. Furthermore, many EVs have a lower ground clearance due to the battery pack; a high-quality detachable system ensures you do not 'ground out' on speed bumps or steep ferry ramps.

When selecting a towbar, consider the weight of your caravan. If you are towing a premium model like the Bailey Unicorn Cartagena or a Coachman Laser 665, the structural integrity of the towbar mount is paramount. You can explore various Caravan Models and Caravan Layouts to see which weights align with your EV's capacity.

The Importance of Dedicated Wiring

Never let a garage use a 'universal' or 'bypass' wiring kit on an electric car. Modern EVs use complex 'CAN-bus' systems that need to know when a caravan is attached. A dedicated wiring loom will:

• Adjust Regenerative Braking: The car will often increase regen to help slow the extra mass of the caravan, protecting your mechanical brakes.
• Modify Cooling: The battery management system may adjust cooling flow to handle the increased thermal load on the motors and battery.
• Safety Systems: It will deactivate rear parking sensors and fog lights, and often enable 'Trailer Stability Assist' within the car's Electronic Stability Programme (ESP).

Noseweight and the 'S-Value'

Because EV batteries are heavy and centrally located, EVs often have excellent noseweight (S-value) ratings. For example, some EVs allow for 100kg on the towball, which is better than many mid-sized diesel SUVs. This makes it easier to balance your caravan correctly for a stable tow. You can check these limits for your specific model in our Find your car's kerbweight database or use our Caravan Towing Calculator to ensure a safe match. If you are unsure about your caravan's weight, our Motorhome Weight Checker (adapted for caravans) can provide guidance on payload management.
