Owners of gasoline and diesel cars could see their fuel consumption drop to 25 percent simply by getting rid of a particular component of their engine this weekend, according to CarShop’s car gurus. They pointed out that car roof racks, accustomed to transporting bicycles, can severely damage a vehicle’s aerodynamics.
Experts have warned that any additional gadget in a car can “decrease aerodynamic efficiency” and increase drag, which increases fuel consumption. They noted that a roof rack can consume up to 25% more fuel, which would be a heavy load. Hit the wallets of motorists who are already struggling.
Even when not in use, an empty roof rack can lead to a 15% increase in fuel consumption. The specialists explain: “Cars are designed to be as aerodynamic as possible, i. e. they are designed to reduce drag, but external add-ons can minimise this aeroefficiency and increase drag. They added: “Roof racks and trunks are not unusual additions to cars, but they can increase fuel consumption, as studies suggest that driving with a hood on the roof consumes up to 25% more fuel. Many possibly think that this is due to the roof chest itself, even if it is empty. Roof racks consume up to 15% more fuel. »

They also gave practical advice for drivers: “Useful tip: Having sunroofs and windows open can also be unnecessary. By opening them only when necessary, energy efficiency can be improved. “
In addition to affecting a car’s aerodynamics, the extra weight from bulky roof racks also contributes to the overall weight, further reducing fuel efficiency, according to the Express.
The professionals at BookMyGarage, the most productive car repair and maintenance comparison site, warn you about transporting heavy parts in your vehicle. They said, “If you’re constantly carrying a lot of heavy goods in your car, you may be consuming more fuel than you are. “Remove motorcycle roof racks or roof boxes that are not in use: Roof boxes accumulate fuel consumption and create significant wind resistance.
Meanwhile, data from RAC Fuel Watch shows a steady rise in gasoline and diesel prices since the beginning of the year. Petrol prices have soared, now averaging 145. 45 pence per litre, up from just 140. 5 pence in January. Diesel prices have also risen by around 7 pence per litre since the start of 2024, with current prices set at 154. 13 pence.
Despite this, RAC experts offer a glimmer of hope to drivers by saying that “no adjustments are expected” in fuel prices over the next few weeks.
