The Pros and Cons of Towing with Electric Vehicles

Towing with an electric vehicle offers a unique set of advantages and challenges. Understanding these can help potential buyers make informed decisions.

Advantages of Electric Towing

• Instant Torque Delivery: Electric motors provide maximum torque from a standstill, unlike internal combustion engines that reach peak torque at higher RPMs. This means EVs can accelerate smoothly and powerfully, even when towing heavy loads.
• Regenerative Braking: EVs can recover energy during braking, which is especially beneficial when descending hills with a trailer. This not only improves efficiency but also reduces wear on braking components.
• Simplified Powertrain: Electric vehicles have fewer moving parts than their gasoline or diesel counterparts. Without complex transmissions or multiple gears, there's less mechanical loss, and maintenance can be simpler.

Challenges of Electric Towing

• Reduced Range: Towing significantly impacts an EV's range. For example, an Audi e-tron SUV towing a 4,000-pound trailer experienced a range reduction of nearly 50% during a long-distance trip.
• Charging Infrastructure: While charging stations are becoming more widespread, they may not be as prevalent or conveniently located as gas stations, especially along certain routes. Charging times are also considerably longer than refueling, which can add substantial time to a journey.
• Payload Limitations: The added weight of batteries can limit the payload capacity of some EVs, affecting how much weight they can safely tow and carry.

Real-World Towing Experiences with EVs

To illustrate the practical aspects of towing with an electric vehicle, let's look at a real-world example.

Audi e-tron Towing Experiment

In 2020, an Audi e-tron SUV embarked on a 504-mile journey from Tulsa, Oklahoma, to Austin, Texas, while towing a 4,000-pound trailer. The trip highlighted some key points:

• Range Impact: The vehicle's range dropped to approximately 105 miles per charge, down from an unladen range of around 190 miles.
• Travel Time: Frequent charging stops extended the total trip duration, as charging an EV, especially with a large battery, takes significantly longer than refueling a gas or diesel vehicle.
• Performance: Despite the reduced range, the e-tron handled the towing task effectively, showcasing the immediate torque and smooth acceleration characteristic of electric motors.

Comparing EVs to Traditional Towing Vehicles

It's important to consider how electric vehicles stack up against traditional internal combustion engine (ICE) vehicles in towing scenarios.
