Trailer weight is a key parameter for anyone planning to tow a caravan, horse trailer, or larger cargo trailer with their vehicle. When comparing approximately four-year-old used cars, the third-generation Volvo S60 emerges from this duel significantly better, offering higher and more consistent towing capacity values than the rival BMW 3 Series (G20 generation).
While standard internal combustion versions of the BMW 3 Series can tow a braked trailer weighing 1,500 to 1,800 kg depending on the specific engine and drivetrain, the Volvo S60 in its mild-hybrid and petrol versions (such as the B4 or B5) confidently and standardly handles exactly 1,800 kg.
A fundamental difference is evident in the plug-in hybrid variants. Due to the integration of heavy batteries and electric drive, BMW limits the maximum towing capacity of the 320e model to just 1,500 kg. In contrast, the Volvo S60 in its top-tier plug-in hybrid versions, such as the T8, is engineered to tow an impressive 2,000 kg.
In practice, these differences mean that with a hybrid Volvo, you can easily tow a large twin-axle caravan or a boat, providing enough capacity for everything from a major weekend haul to a long holiday. The plug-in hybrid BMW, on the other hand, is better suited for a lighter trailer that provides space for a few extra suitcases or for hauling building materials from a DIY store.
If the ability to tow heavy loads is a priority for you, the Swedish sedan is clearly the more robust and practical choice, especially if you are considering a more eco-friendly plug-in hybrid powertrain. While the BMW holds its own in normal use, its electrified variants lack the necessary reserve for more demanding tasks. For both models, an unbraked trailer is traditionally limited by the legislative limit of 750 kg.
