When it comes to the Subaru WRX STI, one of the most frequently asked questions is about its towing capacity. Known for its impressive performance and handling, the STI is often perceived as a sports car rather than a practical vehicle. However, the STI's versatile nature extends beyond its track capabilities, making it a viable option for those who need to tow occasionally. Let's delve into the Subaru STI's towing capacity and explore its towing capabilities.
Understanding the Subaru STI's Towing Capacity
The Subaru STI's towing capacity is primarily determined by its Gross Vehicle Weight Rating (GVWR) and Gross Axle Weight Rating (GAWR). The GVWR represents the maximum weight of the vehicle, including passengers, cargo, and tongue weight (the weight transmitted to the trailer coupling). The GAWR, on the other hand, is the maximum weight that can be placed on an axle. To calculate the towing capacity, subtract the curb weight (the vehicle's weight without any cargo) from the GVWR, and then subtract the GAWR from the remaining figure.
Subaru STI Towing Capacity by Model Year
Before we dive into the towing specifics, it's essential to note that the Subaru STI's towing capacity varies slightly between model years. Here's a breakdown of the towing capacity for the Subaru STI from 2015 to the present:

- 2015-2017 Subaru STI: 2,200 lbs (1,000 kg)
- 2018-2021 Subaru STI: 2,200 lbs (1,000 kg)
- 2022 Subaru STI: 2,400 lbs (1,089 kg)
As you can see, the 2022 Subaru STI has an increased towing capacity compared to its predecessors, thanks to its reinforced chassis and improved suspension.
Towing with the Subaru STI: What You Need to Know
While the Subaru STI can tow a respectable amount of weight, it's crucial to understand that it's not designed to be a heavy-duty tow vehicle. The STI's performance-oriented suspension and low-profile tires are better suited for spirited driving than hauling heavy loads. To ensure safe and enjoyable towing, consider the following tips:
- Stay within the recommended towing capacity to avoid overloading the vehicle and compromising its handling and braking.
- Use a weight-distributing hitch to help distribute the tongue weight evenly across both axles, improving stability and traction.
- Increase tire pressure in both the STI and the trailer to account for the additional weight and heat generated during towing.
- Regularly inspect the trailer's lights, tires, and brakes to ensure they're in good working condition.
- Practice driving and maneuvering with the trailer to get a feel for the increased length and weight before setting out on long trips.
Subaru STI Towing Accessories
To make the most of your Subaru STI's towing capabilities, consider investing in some helpful accessories:

- Trailer Hitch: A high-quality trailer hitch is essential for safe and secure towing. Subaru offers a Class II hitch as an accessory for the STI, which has a 3,500-lb (1,587 kg) tow rating.
- Weight-Distributing Hitch: As mentioned earlier, a weight-distributing hitch helps improve stability and traction by evenly distributing the tongue weight.
- Towing Mirrors: Extended towing mirrors can provide better visibility when driving with a trailer, ensuring you can see the entire trailer and the road around you.
- Towing Package: Subaru offers a towing package for the STI, which includes a trailer hitch, seven-pin wiring harness, and a transmission cooler to help keep temperatures in check during towing.
