Towing capacity is a key factor for many buyers, especially if you plan family holidays with a caravan or need to regularly transport heavier loads. In this regard, there is a vast difference between the two cars, stemming from the very design focus of both models.
While the third-generation Volvo V60 (an ideal and highly sought-after choice on the market for approximately four-year-old used cars) excels as an exceptionally practical family estate, the Lexus IS represents the embodiment of a dynamic sedan focused on a sporty experience. In the available data for the Lexus IS (especially for older high-performance generations and specific versions like the IS F), official towing capacity values are completely missing. In practice, this means that this car is usually not factory-homologated for towing trailers at all, and legal installation of a tow bar is usually not possible here.
In contrast, the Volvo V60 offers an exemplary level of utility. The standard braked trailer weight for entry-level diesel engines, such as the D3 (110 kW), ranges from 1,600 to 1,800 kg. The popular petrol mild-hybrid B3 version can then tow 1,800 kg. However, the maximum braked trailer weight for more powerful versions, such as the B4 Diesel (145 kW) or the high-performance B6 engine, climbs to an excellent 2,000 kg. A huge benefit of the Swedish estate is the fact that even heavy plug-in hybrid powertrains (T6 and T8 Twin Engine) maintain a maximum capacity of 2,000 kg. Unlike many competitors, these hybrid variants do not suffer from reduced towing capacity due to the additional weight of the batteries. The unbraked trailer weight is a standard 750 kg for all versions.
In terms of everyday practicality, these differences are enormous. With the Volvo V60, you can tow a large caravan or a practical trailer without any trouble, giving you additional space for several extra suitcases. The total transport capacity is thus perfectly sufficient for weekend shopping and longer holidays for the whole family. With the Japanese sedan, on the other hand, you will have to rely purely on the internal boot capacity and roof racks.
Conclusion: If a tow bar is a necessity for you and you plan to hitch up any trailer or caravan, the Volvo V60 is the clear and unrivaled winner. You will have to completely rule out the Lexus IS from your selection as a potential tow vehicle due to the absence of towing capabilities.
