"The way the car drives solo bodes well for stability when towing, although sadly very conservative towing limits mean you won't see too many EcoSport's on site next summer. Even the 90PS 1.5-litre diesel is restricted by a legal towing maximum of just 750kg. The same applies to the 125PS 1.0T Ecoboost petrol, while the 112PS 1.5-litre petrol can tow just 700kg or 400kg when fitted with an automatic gearbox".
