Many motorists are unaware that urgent a easy button can considerably scale back their fuel consumption on sweltering days. Most people driving this week shall be placing the air con on of their car.
A crimson Met Office climate warning for excessive heat protecting an space stretching from London to Swansea and Somerset to Birmingham got here into power at 9am on Wednesday, and is because of final till 9pm on Thursday. During the height of the heatwave on these two days, the temperature might come close to the UK’s all-time high of 40.3C, which was measured in Lincolnshire in July 2022.
An knowledgeable showing on BBC Morning Live beforehand revealed that activating a button can forestall the air con system from being overwhelmed by scorching air pouring in from exterior.
Consumer knowledgeable Harry Kind was sharing his data after presenter Rav Wilding raised the query of having car home windows open and the impact it has on fuel financial system. Rav talked about that his car ‘shouts at me’ when he is driving with the home windows open — and requested if it was mendacity about losing fuel.
Mr Kind mentioned: “It’s kind of telling the truth – if you were driving very fast then keeping your windows down will increase drag. That is bad for your car. If you’re going slowly your air con is probably going to use a lot more fuel so it would be worth opening the windows on a hot day through a city to get rid of the hot air inside and if you are going to use air con use the recirculation mode. That will keep the cost down, but ultimately going down the motorway with your windows down – not so great.”
Engaging recirculation mode, even with the air con switched off, can additionally help in holding cabin temperatures down. As Britain enjoys a spell of scorching climate, drivers have been suggested to make use of the dashboard button that can successfully cool their vehicle.

One helpful method is to run the air con — which consumes appreciable energy and due to this fact fuel or battery — for a short whereas, earlier than switching solely to the recirculation button. If the air con is drawing in scorching air from exterior, it requires more energy to cool it down.
By cooling the already lower-temperature air inside the vehicle as a substitute, the system operates far more effectively.
The RAC advises: “Once the air conditioning is blowing cold, close all the windows and switch to (pre-cooled) recirculated air. You can now open the upper air vents and adjust the flow as required. More advanced ‘climate control’ air-conditioning systems allow you to set and maintain a constant temperature within the car.”
Appearing on BBC Morning Live this week, Mr Kind additionally suggested motorists to cut back their motorway speeds in an effort to cut fuel prices, stressing that even a modest discount can make a important distinction. He mentioned: “What makes a huge difference way more than the price of fuel is how you drive. “When you might be motoring alongside I might say scale back your pace.
This is one of the largest elements. The Department for Transport says that going down from 80 to 70 miles per hour saves you 25 per cent on your fuel and likewise it is not unlawful.
“Then when you go down from 70 to 60 that will save you about 9 per cent. The savings get less and less as you get slower and slower.
“When you are driving alongside at these speeds, make sure you are going persistently, you are not breaking all of the time, and ideally use cruise control.”
