Roofbox changes towing sensation
Morning all.
An observation I felt was worth sharing.
I've been towing caravans for some while now but never with a roofbox.
I've just travelled the 300+ miles to Cornwall with our XC70 & 1500kg van with roofboox on the car.
The roof box is aerodynamically shaped Thule made Volvo brand box and the bars Volvo aero wing.
The difference I found was that the caravan was felt less ie no occasional tugs as headwinds changed with wind direction or passing vehicles.
The roofbox clearly acted as a aerofoil. The vehicle fuel consumption stayed the same, 28mpg and SWMBO got to bring even more things than necessary with her.
