The 2026 Buick Enclave Avenir specs start with a 2.5-litre turbo four-cylinder making 328 hp and 326 lb-ft, an 8-speed automatic and up to 5,000 lb of towing in a seven-seat luxury crossover. The Avenir is the top Enclave trim, and it adds comfort and tech rather than more power.

Engine, performance and towing
Every 2026 Enclave trim shares the same turbo four and 8-speed automatic. The Avenir’s mechanical upgrade is its Premium Suspension with Continuous Damping Control, which adjusts the dampers to road conditions.
Buick lists a maximum tow rating of 5,000 lb. Passengers, cargo, options and trailer tongue weight all reduce what you can safely pull, so check the rating on your specific vehicle and the weight limits on the door-jamb label.
Buick does not publish an official 0 to 60 mph time for the Avenir, so treat any figure you see online as an outside estimate.
Size, seating and cargo space
The Enclave is a large crossover at 207.6 in long. Buick’s comparison page also lists a body width of roughly 79.6 in without mirrors.
Cargo volume depends on how many seats are folded. The figures below are the ones Buick published for the 2026 Enclave.
- Behind the third row: about 22.9 cu ft
- Behind the second row: about 57.1 cu ft
- Rear rows folded: 97.5 cu ft
Avenir adds one-touch folding and sliding second-row seats and a power-folding 60/40 third row, according to Buick’s trim details.
Fuel economy and range
Canadian fuel economy is quoted in L/100 km. Guide Auto lists the 2026 Enclave at 9.9 to 12.1 L/100 km depending on drivetrain and driving type. In US figures the front-drive Enclave is rated around 20 mpg city and 25 mpg highway.
AWD is slightly thirstier on the highway. Real consumption varies with speed, winter conditions, load and towing, so use Natural Resources Canada’s fuel consumption guide for the exact rating of the trim you are considering.
What the Avenir adds over lower Enclave trims
The Avenir shares its engine, seating layout and tow rating with Preferred and Sport Touring. What you pay extra for is comfort and appearance.
- 16-speaker Bose Performance audio
- Heated, ventilated and massaging front seats
- Heated second-row outboard seats
- Panoramic sunroof and head-up display
- 22-inch wheels and Continuous Damping Control
- Ultrawide 30-inch display with Google built-in (a feature of the whole 2026 range)
Equipment and packaging differ between Canada and the US. Confirm the exact standard list on Buick Canada’s site or with a dealer.
Safety and driver assistance
Buick lists a broad driver-assistance suite, including forward collision alert, automatic emergency braking, front pedestrian and bicyclist braking, intersection braking, rear cross-traffic braking, blind-zone steering assist, adaptive cruise control and surround-view cameras. Super Cruise hands-free driving is optional, not standard, and its availability on Canadian roads and trims should be confirmed with a dealer.
These systems help the driver but do not replace attention. Crash-test results were not verified for this article, so check IIHS and Transport Canada for current ratings.
Warranty and ownership
Buick sells the Enclave with a limited bumper-to-bumper warranty and a longer powertrain warranty. The terms in Canada are quoted in kilometres and differ from the US mileage terms, so ask a dealer for the current Canadian coverage in writing.
Who the Avenir suits, and alternatives
Choose the Avenir if you want a quiet, comfortable family hauler with premium seats and audio and do not need extra power. If you only need seven seats and the 5,000 lb tow rating, the lower trims share the same drivetrain.
For the rest of the range, see our Buick Enclave specs guide. If towing is your priority, compare it against other SUVs that can tow 5,000 lb.
