Is the Vauxhall Crossland's fuel efficiency affected by adding a roof rack?

I'm planning on taking a road trip and I'm wondering if adding a roof rack to my Vauxhall Crossland will affect its fuel efficiency. Should I leave it off to save on gas or will it not make much of a difference?

The addition of a roof rack does actually have an impact on the aerodynamics of your car which ultimately affects fuel efficiency. However, the effect is usually not very significant unless you're driving at high speeds.

Based on my personal experience, I've found that adding a roof rack does decrease fuel efficiency by a small percentage. My suggestion would be to remove it when you're not using it so as to not have a constant impact on your fuel consumption.

If you're planning on taking a road trip, I would suggest investing in a fuel-efficient vehicle instead of worrying about a roof rack. The impact of a roof rack on fuel efficiency will likely be minimal compared to the overall fuel consumption on a long trip.
