It's 6:40 on a January morning in West Islip. The windshield is frosted, the driveway is crunchy, and the range estimate on your IONIQ 5 reads lower than it did when you parked last night. Nothing is wrong with the car. That's simply what cold does to an electric vehicle, and a little preparation in November turns those mornings into routine. Here's how we at Atlantic Hyundai suggest getting ready.
Why Cold Weather Changes the Math
Lithium-ion batteries behave a lot like people on a cold morning: they get sluggish. Chemical reactions inside the cells slow down as temperatures fall, so the battery can't deliver or accept energy as easily as it does in June. That's why your range estimate shrinks overnight and why charging can take longer after the car has sat outside.
Heat is the other half of the story. A gas engine throws off warmth as a byproduct, but your IONIQ 5 has to create cabin heat from the same battery that moves the car. Defrosting, heating the cabin and warming the battery itself all draw from one source, and short trips are where you notice it most. A ten-minute run to the King Kullen spends a big share of its energy just getting warm.
Range comes back as temperatures climb in spring. Think of winter as a season where you plan with a little extra cushion, the way you'd leave earlier when the Southern State is slick, rather than a season when the car lets you down. Most of what follows is about building that cushion without much effort.
Tires Matter More Than You Think
Winter tires or all-season?
Rubber stiffens in the cold. All-season tires harden as the thermometer drops, while dedicated winter tires use a softer compound and thousands of tiny slits, called sipes, that bite into slush and ice. Long Island rarely gets upstate-style snow, but it gets plenty of freeze-thaw, black ice on overpasses and side streets that wait a day or two for a plow.
If you can work from home on storm days, good all-seasons with healthy tread may be enough. Commuters who head out before the plows on Sunrise Highway are usually happier on a winter set. A second set of tires mounted on their own wheels makes the spring and fall swap quick and saves wear on the tire beads. Our parts department can help you match wheels and tires to your trim.
Watch the pressure
Cold air contracts, so tire pressure drops when the weather turns. Check it about once a month in the morning, before you drive, and inflate to the number on the driver's door jamb rather than the maximum printed on the sidewall. Soft tires cost you grip and range at the same time.
On qualifying purchases, Atlantic Edge includes tire and wheel coverage, which is worth remembering during pothole season on Montauk Highway.
Rear-Drive or All-Wheel Drive?
The 2027 IONIQ 5 lineup splits cleanly. The SE Standard Range, SE (2WD), SEL (2WD) and Limited (2WD) send power to the rear wheels. The SE (AWD), SEL (AWD), Limited (AWD) and XRT drive all four.
A rear-drive IONIQ 5 on proper winter tires handles a typical Long Island winter well. Stability and traction control help, and the battery's weight sits low in the car. Where all-wheel drive earns its keep is getting moving: pulling out of an unplowed spot at the train station, climbing a sloped driveway, or merging from a slushy on-ramp. It helps you go. It does not help you stop or turn, so tires still come first.
There's a trade-off to weigh. The XRT carries a combined efficiency rating of 94 MPGe, while the rear-drive SE (2WD) is rated at 114 MPGe, and that gap matters more in winter, when every bit of range counts. If you're torn, book a test drive of each layout and drive the roads you actually use.
Charging Habits That Pay Off
Your best winter tool is the plug in your garage. Charging overnight at home means you leave each morning with a battery that has been kept topped up, and a garage, even an unheated one, keeps the pack warmer than a driveway exposed to wind off the Great South Bay.
A few habits make a real difference:
- Keep a bigger buffer. Avoid coming home close to empty, since a cold night will shave more off the estimate by morning.
- Charge after driving, not before. A battery that's been warmed by a drive accepts a fast charge more readily than one that's been sitting in a cold lot.
- Use conditioning if your car offers it. Some setups can warm the battery on the way to a fast charger; check your owner's manual for the right setting.
- Set a charging schedule. Finishing a charge close to your departure time means the battery is still warm when you pull out.
Public chargers bring their own winter quirks. Snowbanks pile up around stalls, cables get stiff, and ice can glaze over the charge port door. Tap the ice loose or let the cabin warm the car a few minutes rather than forcing anything open.
Warm Up While You're Still Plugged In
Here's the single easiest win of the season: heat the car while it's still connected to the charger. The energy for that first blast of warmth then comes from your home's electricity instead of the battery, and you leave with a clear windshield and a full charge. If your car or the Hyundai app lets you schedule climate control, set it for ten or fifteen minutes before you usually leave.
Once you're moving, warm yourself rather than the whole cabin. Heated seats and a heated steering wheel, on trims that have them, use far less energy than pushing hot air through the vents. Many drivers find they can turn the cabin temperature down a few degrees and stay comfortable.
For foggy glass, fresh air with the defroster works better than recirculation, which traps moisture from wet boots and coats. Before you pull out, brush the snow off the roof, hood and lights, not just the windshield. A sheet of ice sliding off at highway speed on the LIE is a hazard to the driver behind you. With no tailpipe, you also don't have exhaust building up while the car warms in a closed garage.
Salt, Sand and Shore Air
Long Island towns pre-treat roads with brine and spread salt and sand after storms. If you drive the Robert Moses Causeway or anywhere near the water, you also pick up salty spray on windy days. That mix settles underneath the car and works its way into seams, brackets and brake parts.
Electric vehicles have a quirk here. Because regenerative braking does much of the slowing, the friction brakes get used less, and rotors that rarely heat up can collect surface rust faster. A few firm stops on a quiet road now and then help keep them clean.
A simple washing routine
Aim for a wash with an underbody rinse every couple of weeks through the salt season, and soon after a storm once roads dry. Pick a day above freezing when you can, and wipe the door seals and charge port door afterward so they don't freeze shut. All-weather floor mats catch the slush and salt your boots carry in.
Atlantic Edge, which comes with qualifying purchases, includes interior and exterior protection plus a car wash with service visits, so a winter checkup leaves you with a cleaner underside too.
A Storm-Day Plan and a Small Kit
Nor'easters usually give a day or two of warning. Use it. Charge higher than you normally would the night before, since you may face slow traffic, detours or a long wait with the heat running. Park nose-out if you can, so you aren't backing into a plow ridge the next morning.
An electric car is a decent place to wait out a stall on a closed road. With no engine idling and no exhaust, you can keep the cabin warm for a long stretch on a healthy battery. Check that snow isn't packed around the car, crack a window slightly, and keep the heat moderate rather than maxed out.
A small kit in the cargo area covers most surprises:
- Snow brush and ice scraper
- Compact folding shovel
- Warm gloves, hat and a blanket
- Phone charging cable
- Bag of sand or traction mats
- Flashlight with fresh batteries
- Spare jug of winter washer fluid
With 26.3 cubic feet of cargo space behind the rear seats on every 2027 IONIQ 5 trim, this fits under the cargo cover with plenty of room for groceries.
West Islip, NY
- Tires matter more than drivetrain; winter tires on all four corners help any IONIQ 5 trim stop and turn on ice.
- Charge and warm the cabin while still plugged in, and keep a bigger range buffer on cold nights.
- Rinse off road salt every couple of weeks and handle wipers, fluid, chips and the 12-volt battery before the first storm.
