Which Buick and GMC models offer all-wheel or four-wheel drive, what the difference actually is, and what all-wheel drive will not do for you. Written for the Region, where US-30 can be wet in Valparaiso and snow-covered in Chesterton on the same afternoon.
For most Region drivers, a front-wheel-drive vehicle on four winter tires handles a Northwest Indiana winter perfectly well. All-wheel drive is worth paying for if you have a hill, an unplowed driveway, a county road the plow reaches late, or a shift that starts before anything has been cleared. Four-wheel drive with a low range is for towing, deep snow and job sites rather than a plowed commute.
If you want the one-line version: all-wheel drive helps you go, tires are what let you stop. Buy the tires first and the drivetrain second.
| If this is your winter | What we would put you in |
|---|---|
| Town driving, plowed roads, garage parking | Front-wheel drive on winter tires. Buick Envista or a front-drive Terrain or Encore GX. |
| Commuting from Portage, Chesterton or the Dunes side | Available all-wheel drive. GMC Terrain or Buick Encore GX. |
| Family, car seats, three rows | Available all-wheel drive. GMC Acadia or Buick Enclave. |
| Rural road, long driveway, you clear it yourself | Four-wheel drive. GMC Sierra 1500 or Canyon. |
| Towing a trailer or hauling equipment through winter | Four-wheel drive with a low range. Sierra 1500 or Sierra HD. |
| You want the margin and the room, budget allows | Four-wheel drive full size. GMC Yukon or Yukon XL. |
The two get used interchangeably in advertising, and they behave differently. Which one you want depends on what your winter actually looks like rather than which sounds more capable on a spec sheet.
Most of a Region winter is plowed road, slush and refreeze. Some of it is a county road the plow reaches late, a driveway nobody clears but you, or a trailer that needs moving regardless of what fell overnight. Those are two different answers.
| All-wheel drive | Four-wheel drive | |
|---|---|---|
| How it engages | Automatic. Sends power rearward when it senses slip. You do nothing. | Usually driver-selected, with a low range for deep snow and heavy pulling. |
| Best for | Plowed roads, slush, black ice, changeable conditions. Most of a Region winter. | Unplowed roads, deep snow, towing, job sites, rural drives the plow reaches late. |
| On dry pavement | Leave it alone. It manages itself. | Generally not meant to be left engaged. |
| Models here | Encore GX, Envision, Enclave, Terrain, Acadia | Sierra 1500, Sierra HD, Canyon, Yukon, Yukon XL |
Three of the four Buick crossovers offer all-wheel drive. The fourth does not, and we would rather say so here than have you find out in January.
The smallest Buick crossover you can get with all-wheel drive. Easy to park, easy to see out of, and enough ground clearance for a side street the plow has not reached yet.
View Encore GX →A step up in size and quiet. The longer wheelbase settles down on rutted snow and the cabin stays civil on a cold commute down US-30.
View Envision →Three rows with available all-wheel drive. The Buick answer if you are moving kids, car seats and a week of groceries through a snow band.
View Enclave →Straight answer: the Envista is front-wheel drive in every trim and there is no all-wheel-drive version. It is a good-looking, well-equipped crossover and one of the least expensive ways into a new vehicle. But if all-wheel drive is why you are shopping, look at the Encore GX instead.
View Envista →The SUVs run all-wheel drive, the trucks and full-size SUVs run four-wheel drive with a low range. Configurations vary by trim, so check the window sticker on the specific vehicle.
The practical one. All-wheel drive available, which matters when the lake effect comes off Michigan sideways in January and your commute mixes cleared highway with an uncleared side street.
View Terrain →Midsize three-row with available all-wheel drive. More room than the Terrain without stepping all the way up to full size.
View Acadia →Full-size, available four-wheel drive, and the ground clearance for what the plow leaves at the end of your driveway. The XL adds cargo room behind the third row.
View Yukon →Available four-wheel drive with a low range. If you plow, tow, or drive a rural road the plow reaches late, this is the one. Worth adding weight over the rear axle for winter.
View Sierra 1500 →Gooseneck towing, equipment hauling and the work a half-ton is not rated for. The industrial corridor through this Region runs on them, snow or not.
View Sierra HD →Most of the capability of a full-size truck in something that fits a normal garage and a normal parking space.
View Canyon →This is the most useful thing on this page, so we will put it plainly. All-wheel drive helps you go. It does not help you stop or steer. Braking and cornering grip come from your tires, and that is where lake-effect snow catches people out.
Winter tires use a rubber compound that stays pliable below about 45°F. All-season tires stiffen in the cold and lose grip long before the tread wears out. A front-wheel-drive car on proper winter tires will out-brake an all-wheel-drive SUV on worn all-seasons, every time. If you can only do one of the two this year, do the tires.
Put a quarter upside down in the tread groove. If you can see the top of Washington's head you are at or below 4/32 of an inch. The penny test at 2/32 is the legal minimum, not a winter recommendation.
If you fit winter tires, fit four. Two on the drive axle and two all-seasons on the other end gives you a vehicle that grips at one end and lets go at the other.
Roughly 1 PSI for every 10°F the temperature falls. A tire that was correct in October is low by December, and low pressure costs you grip and fuel.
A battery that starts the car in November at 50°F may not at 5°F in January. A load test takes minutes and is the single most common reason people get stranded.
Sometimes, and not always. It is an option with a price on the window sticker, it carries a small fuel economy penalty because there is more hardware turning, and it adds driveline components that need servicing over the life of the vehicle. It also tends to help resale in a snow market like this one.
The honest test is your own roads rather than a rule. Think about the worst five mornings of last winter, not the average one. If you got through them, front-wheel drive and good tires will do it again. If you did not, or if you had to call someone, that is what the option is for.
You drive plowed roads, park in a garage or a flat driveway, work normal hours, and can wait an hour on the worst morning of the year. Spend the difference on tires and a battery test.
You have a hill or a long driveway, drive a county road before the plow, start a shift at four in the morning, carry people who cannot be late, or simply do not want to think about it.
You tow through winter, haul equipment, plow, or regularly drive surfaces that nobody clears. The low range is the part that matters, and it is not something all-wheel drive substitutes for.
Four winter tires change stopping distance more than any drivetrain does. If the budget only stretches to one upgrade this year, this is the one that keeps you out of the car in front.
A new vehicle is not the only answer, and for a lot of people it is not the right one. Our used lot is not limited to Buick and GMC because we take trade-ins from every brand, so used all-wheel-drive crossovers and four-wheel-drive trucks of most makes come through regularly.
The great majority of our used inventory is certified through CarBravo, General Motors’ certified used programme. Unlike most manufacturer programmes it is not limited to the franchise brand, so a used Toyota, Honda or Ford taken in on trade can be certified the same way a used Sierra can. Certified means inspected with warranty coverage behind it rather than sold as-is.
A dedicated selection under twenty thousand. If you want all-wheel drive on a budget and do not care whose badge is on it, start here and call to confirm what is physically on the ground.
Under $20,000 →Inspected, warranty-backed, and not restricted to GM vehicles. The useful difference between a certified used AWD crossover and a cheap one with no history behind it.
Certified used →Used trucks, SUVs and crossovers across most makes. Worth calling before you drive over, because the good all-wheel-drive stock moves quickly once the first snow lands.
Browse used →Availability varies by model and trim, so check the window sticker on the specific vehicle. These are the ones that earn their keep between December and March.
Warms the cabin and starts clearing the glass before you walk out. On many models it triggers the heated seats and mirrors at the same time.
Heat reaches you faster than the cabin heater can warm the air, which is the whole difference on a short cold drive across town.
Clears the salt haze and the refreeze that wipers never reach. Worth more than it sounds on a dark January commute.
Useful when the back glass is covered and the snowbank at the end of the row is taller than the car.
Service is open Saturdays, which is usually when people actually have time to deal with this. A winter readiness check covers the battery, the tires, the wipers and washer fluid, and the all-wheel-drive or four-wheel-drive system itself — worth confirming it engages before the morning you need it to.
Book it before the first hard freeze rather than after the first storm, when the phone rings all day. Schedule service → or see Saturday service →
