Across Europe around 25% of vehicles have tow balls fitted—but there are distinct regional variations, being more common in Benelux and Scandinavia. In Sweden, around 2.2 million cars of around 4.3 million (just over 50%) have tow balls. In the United Kingdom the popularity of caravans is responsible for a large proportion of four-wheel drive (SUV) vehicles being fitted with tow hitches.
