2018 Buick Enclave: How engineers made it larger, lighter, more sophisticated

Buick used the unveiling of the 2018 Enclave at the New York Auto Show to introduce its new range-topping Avenir sub-brand to the world. With fancier interior finishes and exterior details, it's Buick's latest effort to make itself a proper luxury brand (or perhaps re-establish itself as such). However, lost in the Avenir song and dance is the fact that the 2018 Buick Enclave is a (very) long-awaited all-new model regardless of the trim level one selects. Like the Chevrolet Traverse upon which it is based, the new Enclave is bigger than the vehicle it replaces but considerably lighter, by about 400 pounds. "We told every engineer, 'get your job done, but then take the weight out,'" said engineer Rick Spina as we hovered next to his larger yet lighter creation. His team therefore set about taking a little bit of weight out from just about everywhere, from using additional aluminum in the suspension to varying the thickness of the frame (thicker in places that needed to be stronger, thinner and therefore lighter in places that didn't). Only about 100 pounds came out of the body with the rest coming from elsewhere. Not only will the reduced weight improve fuel economy (Buick-estimated at 19 mpg combined with FWD versus 18 for the 2017 model) and presumably the old Enclave's rather ponderous handling, but it should only make things easier for the new powertrain: General Motors' now-familiar 3.6-liter V6 and its latest nine-speed automatic. With 302 horsepower and 260 pound-feet of torque, Buick says the new engine will need 7.2 seconds to reach 60 mph with FWD or 7.5 seconds with AWD. That's a second quicker than before. Besides acceleration, towing is also bumped up by 500 pounds to 5,000. For those models with all-wheel drive, the Enclave has the same basic system featured on range-topping versions of the Buick LaCrosse. Besides power being sent front and rear, it can also differ from right to left in the back, although Spina is quick to point out that capability is for traction-enhancing purposes rather than sporty, handling-enhancing torque-vectoring ones. Buick owners already appreciated the Enclave for its quietness so the engineers decided to take it that much further. This included altering the exhaust, improving body sealing (there are triple door seals), including active sound deadening and utilizing advanced materials that absorb sound as opposed to simply being thick, dense and heavy enough to keep it out.

Buick Enclave spy photos reveal curvy, minimal interior

We got a pretty good look at the next-generation Buick Enclave last month via some spy photos, and this month we get a peek inside. While the exterior takes after the Wildcat concept, the interior follows in the path set by the recently redesigned and launched Encore GX and Envista. The focal point of the new Enclave's interior is the curved screen panel encompassing both the instrumentation and the infotainment. It has the rounded, inverted trapezoid look of the little Buicks, but from the gap in the screen covers, it looks like the screens will fill up the housing much better on those base crossovers. Just below the infotainment side of the screen array is a minimalist set of climate control buttons (piano key style) and a pair of air vents. It's difficult to tell much else of the dash due to the coverings. Based on the little Buicks, the screen probably sits on a small alcove with the rest of the dash being smoother and wrapping around behind the screen. The steering wheel isn't shared with the smaller Buicks, nor does it appear to be that similar to what we've seen in either the new Chevy Traverse or the GMC Acadia. It has a sleek, simple three-spoke design with a small circular center horn and airbag section. We also noticed the black plastic strip at the top of the wheel that likely houses the lighting and infrared sensors that go along with GM's Super Cruise hands-free highway driving assist. We're expecting the Enclave to be revealed soon, possibly early next year, with deliveries coming soon after. This is because this prototype looks pretty much production-ready, and we've already seen its cousins from Chevy and GMC. It will likely get the same turbocharged 2.5-liter four-cylinder making 328 horsepower and 326 pound-feet of torque with an eight-speed automatic and either front- or all-wheel drive. Related video:

Buick Envision Plus is a seven-seater tweener developed for China

Buick has filled the gap separating the Envision and the Enclave with a new crossover named Envision Plus. Launched at the Shanghai auto show, the three-row people-mover is scheduled to go on sale in China later in 2021. The plus-sized Envision stretches 190.7 inches long, 74.1 inches wide, and 66.7 inches tall, figures that make it around eight inches longer and two inches taller than the regular Envision. It's also a full 14 inches shorter, four inches narrower, and three inches lower than the Enclave, which is the biggest crossover in the Buick range. Designers didn't settle for stretching the Envision's wheelbase. They gave the Plus a more upright front end characterized by a taller grille, a flatter and longer roofline, and a redesigned rear end accented by a strip of bright trim that connects the lights. Only photos of the upscale Avenir trim (shown above) have been published so far. Images of the cabin are not available yet. We expect the Plus offers an interior close to the standard Envision's — from the driver's point of view, at least. The biggest difference is that the longer Envision lives up to its name by letting motorists take more gear or kids along for the ride thanks to a more spacious trunk and third-row seats. Power for the Envision Plus comes from a turbocharged, 2.0-liter EcoTec four-cylinder engine fitted with 48-volt mild-hybrid technology. Bolted to a nine-speed automatic transmission, the turbo-four is the same basic engine found in the American-spec Envision, where it develops 228 horsepower and 258 pound-feet of torque, but figures for the Plus weren't released. Front- and all-wheel-drive models will presumably be available. Buick will release pricing information closer to the model's on-sale date. As of writing, the Envision Plus has only been announced for China, where it will be built, but unverified reports claim it will arrive in American showrooms before the end of 2021. We've reached out to the company, and we'll update this story if we learn more. 2021 Buick Verano Pro GS View 5 Photos What else did Buick show in Shanghai? Buick no longer sells sedans in America, but it remains present in that segment on the Chinese market. In addition to the Envision Plus, it unveiled a model named Verano Pro developed specifically for China, built locally, and aimed at relatively young buyers. At launch, motorists will be asked to choose between the regular sedan and a sportier-looking variant that wears the storied GS emblem.
