Tow Bars for Electric Vehicles in Australia
What it costs, which EVs can tow, and what you need to know before fitting a towbar to your EV.
Does fitting a tow bar affect EV range?
An empty towbar with nothing attached has almost no effect on range (less than 2% from aerodynamic drag). Actually towing is a different story — expect 30–50% range reduction with a trailer or caravan attached, more for boxy loads.
Which EVs can tow in Australia?
Tesla Model Y: 1,600kg braked. Tesla Model 3 Long Range (2023+): 1,000kg. BYD Atto 3: 750kg. Kia EV6: 1,600kg. Hyundai Ioniq 5: 1,600kg. Polestar 2: 1,500kg.
EV-specific wiring
Most EVs require 13-pin wiring with full CANbus integration. This unlocks "towing mode" in the car's software — which adjusts regen braking, stability control and range estimates. Cheaper 7-pin retrofits work for lights only but won't enable manufacturer towing features.
Top EV models and towing specs
The Tesla Model Y is the most-towed EV in Australia, easily handling boats and small caravans. The Kia EV6 and Ioniq 5 have higher rated towing capacities (1,600kg braked) and are popular with caravan owners.
Why EV towbar installation is more expensive
EVs need approved towbars, 13-pin CANbus wiring, and software activation. The install takes 4–5 hours versus 2–3 for a petrol car. Expect $850–$1,850 fitted, with Tesla and European EVs at the higher end.
