Millions of drivers ignore ‘hidden' button that keeps your car cool in hot weather and saves on fuel
When a heatwave hits, hopping back into your parked vehicle is never a pleasant process.

But now motorists are sharing a tip about an easy-to-miss button on the dashboard.
The button is marked by a little arrow with a symbol of the car.
It's called the "recirculate air" button, and it can cool down your cabin even with the air con off.
According to Virtual Driving Instructor, the button could be a "life-saver on a scorcher of a day".
And it also helps to save on fuel.
The expert said: "When you press this button, it stops any air from outside coming through these vents, circulating the air inside the cabin."
Pressing both the air conditioning and recirculating air buttons can be really helpful, as they "keep all the cool air inside the cabin".
It works by cutting off the outside air, instead recirculating what's already in the car.
This brings down the temperature when the air outside the car is hotter than the air inside.
To ensure this is the case, blow the aircon for a couple of minutes and then hit the recirculate button - rather than swapping it for warmer outside air.
NO NOISE Drivers will risk $1,000 fines if they fail to install car feature under new law – few will be exempt
That could even allow you to switch the air con off, saving on fuel.
Fuel prices remain high with the average price of a tank costing £75, so it could be a timely piece of financial advice.
The RAC agrees and offers another tip to drivers who are looking to save cash on hot days.
It said: 'Start driving, but keep the car windows open for a minute or two to let all the hot air escape, do this until the air from the vents feels cooler than the outside temperature.
"Once the air conditioning is blowing cold, close all the windows and switch to (pre-cooled) recirculated air."
Four-step guide to keeping car cool
By Jacob Jaffa
First of all, start driving for a couple of minutes before turning on the AC as this can improve it's power.
Consumer Reports experts said: "Your car air conditioning works much better when you're actually driving because the faster the engine turns, the faster the AC compressor runs, which lets the system cool more effectively.
"Don't waste time and fuel by letting your car run before you go."
Once you're up and running, open all the windows fully for between 10 and 20 seconds to let hot air out and make the air con's job easier.
Then, when cold air has started to come through the vent, roll up the front windows but keep the rear windows cracked open.
Doing this for another 10 to 20 seconds will pull the cooler air through into the back of the car, helping to achieve a better all-around chill.
Finally, set the temperature as low as it will go and adjust the fan speed and aim to your preference

Engineer behind Senna and Prost's dominance in McLaren builds £400k lightweight supercar with F1-inspired cockpit
A FAMOUS engineer who was the brains behind one of Formula 1's most famous and dominant cars has designed a stunning, F1-inspired supercar. Steve Nichols, 78, was once responsible for the McLaren MP4/4 that reigned over the F1 championship with Ayrton Senna and Alain Prost in 1988. 6 6 6 6 6 It was heralded at the time for its low-slung, sleek design - making it one of the fastest and most efficient cars of its era that was heavily optimised for aerodynamics. Powered by a beefy, V10 Honda engine, the MP4/4 was also renowned for its reliability and efficiency - giving McLaren a significant edge. McLaren were able to secure 10 one-two finishes during the season, as Senna secured the first of his three world championship titles. Now, some 36 years later, Nichols has put all of his engineering ingenuity to the test by building a supercar that blends modern appeal and classic motorsport heritage. Called the Nichols N1A, the car is said to be a modern reinterpretation of the McLaren M1A from the 1960s - the brand's very first self-designed and built race car. The Nichols N1A utilises a lightweight bodywork and has been described as a driver-focused machine that draws heavily on its racing heritage. Powered by a reworked 7.0-litre LS3 V8 engine producing 650 horsepower, it also features a six-speed manual transmission - to ensure a pure, engaging dr i ving experience. In fact, according to Autoblog, the car has a higher power-to-weight ratio than a LaFerrari. The design, which also pays homage to the aforementioned McLaren MP4/4, features a reclined driving position much like an F1 car, analog gauges and a gear lever reminiscent of Senna's F1 car. The interior is minimalist and focused on the driving experience, with machined aluminium controls and premium leather trim. For the purists, modern conveniences like touchscreens have been excluded. As you can imagine, the sporty motor is both pricey and exclusive, with only 100 units set to be produced - with the first 15 models under the 'ICON 88' banner which celebrates the 15 victories of the McLaren MP4/4 in 1988. Each car costs $500,000 - roughly the equivalent of £372,000 - and is customised to the buyer's preferences. The N1A is the debut model from Nichols Cars, which was founded in 2017 by Nichols and John Minett, with a goal to create pure, exhilarating that honour motorsport history.

Want a used electric car? A simple battery test would provide consumer confidence
'It says it will do 226 miles and it has 84 per cent charge,' said my friend of the Polestar 2 he was considering buying. 'Does that mean the battery is in good shape?' I told him I had no way of knowing for certain, but I could make an educated guess – that this would equate to a real-world range of around 270 miles, suggesting the battery on this two-year-old car was roughly as healthy as it had been when new. Its state of health looked good. But that guess depended on countless variables: how heavy-footed the previous driver had been; how often it had been rapid-charged; whether it had been fully or partially charged each time; even the weather on that particular day. And since battery degradation is the main concern for anyone buying a used electric car, there has to be a better way than guesswork to gauge exactly how well a battery is still performing. Simple test Of course, there is a better way. A battery state-of-health (SoH) check is a simple test: plug a scanner into the car's diagnostic port, interrogate the software, and the battery management system will provide a readout of the percentage of the battery's original capacity that remains. State-of-health certification could be a boon for British car dealers, who are currently struggling under the weight of an oversupply of electric cars. For years, government incentives have heavily favoured EVs as company cars, flooding the new car market. Yet seemingly little thought has been given to what happens when these cars return from their leases and enter the used market. EVs dumped on dealers Used car buyers are becoming more open-minded about EVs, but there's still a way to go – and there aren't enough ready to take the plunge to fully absorb the huge number of EVs being dumped on dealers. 'There still seems to be division between those who are open to EVs and those who would rather walk,' says Ashley Winston, the director of vehicle sourcing company Palmdale Car Finders. 'But this divide is definitely reducing. 'I think people are realising that EVs will be the vast majority of options in the future and are just accepting it. So buyers are indeed becoming more open-minded – but not massively. 'Additionally, it's difficult to see the effect on the used EV market because there is still a glut of cheap used EVs. I think that the over-supply will last for a long while.' This over-supply is having an effect on trade-in values of EVs that return to the used market later on. 'A lot of dealers still refuse to stock EVs,' Winston explains. 'Those that do will only buy them for stock if they are very cheap, which makes sense as EVs depreciate. If we have an EV to trade out, we expect very low offers.' Buyers' concerns So could SoH testing make a difference? Certainly, buyers are worried about the potential for battery degradation in used EVs. A 2023 survey of 2,000 British drivers by the Green Finance Institute found that 62 per cent of those who said they wouldn't buy a used EV named their main reason as their concern about battery lifespan. It's a concern shared by dealers – 45 per cent of whom say that they would avoid bidding at auction on used EVs that don't come with any information on their battery health, according to recently released research by trade-to-trade auction site Dealer Auction. Some auction houses have cottoned on to this fact. BCA, for example, now offers battery health scores on its EVs. So why shouldn't dealers be compelled to pass on this same level of reassurance to buyers? 'I'm not sure how realistic it is that this becomes law,' says Winston. 'I think that if that were to happen, non-franchised dealers would struggle purely with the equipment needed to generate an EV battery health report. 'The reality is that this will be a change and the used car industry doesn't handle change well. That said, an EV battery certification is just an add-on to a pre-approved preparation process anyway. Some might say it's simpler than needing an oil and filter change. 'That would open up the market for an independent company to offer such a service to dealers. In reality, it's just a plug-and-play option. I suspect the technology is there to do it remotely, too.' Why isn't battery SoH a regulation? There's a chance that regulation might not even be necessary. Some dealers are starting to recognise that a SoH certificate is a useful sales tool. Scan the classified adverts for electric cars and you'll already find some with mentions of a certified battery health figure. 'Dealers have been slow to adopt it,' says Winston, 'but hopefully more franchised dealers will start doing so soon. I don't know any independent dealers which offer it yet, though.' And if the dealers don't get there, the manufacturers may beat them to it. The latest Toyota bZ4X electric car, for example, has an option in the instrument binnacle menu to display the current SoH, enabling potential buyers to check with no more than a few button presses from inside the car. It's one of the first models to do so – but there's a strong chance that more will follow. Preaching to the converted Winston remains unconvinced that SoH certification will be a silver bullet to get second-hand buyers more interested in EVs. 'Range and charging are still the biggest objections,' he says. 'Although I don't think battery certification will move that many more people to buy an EV, I do think that battery certification will be of importance for people who have already decided to buy an EV.' Either way, if the Government wants to incentivise people to make the switch into EVs, it would do well to remember that it's no good foisting them on new car buyers without some sort of strategy to deal with those cars when they arrive on the second-hand market at the end of their lease. SoH certification might not be the be-all-and-end-all, but it would certainly remove the guesswork for buyers of second-hand cars who do decide to go electric – and that might in turn help to incentivise a few more to do so.

Car Deal of the Day: we've never seen the Cupra Born this cheap
Stylish design; premium feel 347-mile range; great fun to drive Just £199.81 a month The Cupra Born neatly mixes a sporty driving experience with an upmarket feel. It's also a car you usually have to pay pretty handsomely for – but not right now. Scouring the Auto Express Buy A Car service, we found Leasing Options is offering the desirable EV for under £200 a month – and that's down to the Government's Electric Car Grant. After a not-unreasonable £2,747.11 initial outlay, the Born requires 24 monthly payments of £199.81, which constitutes excellent value for money. There's an annual mileage cap of 5,000, but you can bump this up to a far more flexible 8,000 for just under £20 a month more. Advertisement - Article continues below You'll be getting the keys to the entry-level trim, but this is no problem as Cupra tends to give its cars a high level of standard equipment. On the Born, V1 trim gets you sports bucket seats trimmed in recycled materials, full LED front and rear lights, a heated steering wheel and a 12.9-inch touchscreen with Apple CarPlay and Android Auto. The deal also gets you the largest battery on offer in the Born. This gives a claimed range of 347 miles, while the 79kWh pack has a maximum DC charging speed of 175kW, so rapid charging takes around 30 minutes. This model adds aero-styled 20-inch alloy wheels for a really sporty look. The Born gets a rear-mounted electric motor that packs 228bhp, delivering a pretty rapid 0-62mph acceleration time of 7.1 seconds. An 'e-boost' button on the steering wheel provides a short extra punch of power when overtaking. It's a fun car to drive, too. Although heavily based on the Volkswagen ID.3, the Born feels sharper and more engaging on the road. It's a more direct steer with a firmer ride – perfect for those who want some fun from their EV, but not at the cost of practicality and range.
