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's new logo ditches the ring, levels the shields

Buick's logo is about to receive a relatively major update. The new-look emblem appeared in a trademark filing in March 2022, and a leaked image posted on social media has given us a better look at the design that should appear on production cars in the not-too-distant future. Published on Instagram by an account called Buick_Saudi_Arabia, the photo shows what seems to be Buick's new logo on the middle of a steering wheel. The changes made aren't groundbreaking, but they're certainly noticeable. The ring is gone, and the red, white, and blue shields are separated from each other and positioned on the same level. As of writing, the shields are staggered and surrounded by a ring.           View this post on Instagram                       A post shared by Buick Saudi Arabia (@buick_saudi_arabia) One question that comes to mind is: why now? Buick has used its current logo for decades without significantly updating it, so what prompted the company to give the design a makeover? Several factors undoubtedly influenced this decision, but one that's worth shining light on is that the brand is no longer twinned with Germany-based Opel. For many years, some Opel-designed models made their way to the United States with Buick emblems on both ends. No one in Europe has heard of a Buick Regal; folks there know the sedan as the Opel Insignia. And, since the visual differences between these cars were often minor, using a Buick logo whose basic silhouette was similar to Opel's logo simplified the design process. Neatly integrating, say, Chevrolet's bowtie-shaped emblem into the Insignia's grille would have been harder, though more improbable acts of badge-engineering have been committed (the Ford Maverick was once a Nissan). General Motors sold Opel to PSA Peugeot-Citroen in 2017, and both carmakers are now part of Stellantis, so Buick's trans-Atlantic design ties have been cut. Losing the Opel connection gives Buick's design team more leeway to experiment with new ideas, like a revamped logo. Keep in mind that nothing is official yet. Full details and an explanation of what the new logo means should emerge soon. Why the shields? Buick isn't rooted in sword-fighting, so why have shields appeared on its cars for over 60 years? The answer, according to Buick, is relatively vague. What's certain is that the tri-shield logo didn't appear on Buick's early cars.

GM may have teased a whole group of electric vehicles

During GM's big CES press conference, the automaker highlighted a number of its upcoming electric car-related projects from delivery vans to the upcoming flagship Cadillac Celestiq. In the middle of it all, a collection of mystery cars sat in the background behind speakers. They were in the dark, lit only with their running lights, and while it's possible they're just generic filler cars or concepts, we think they could be future products. Our best shot of the cars together is shown above, and we can pretty easily identify three of the vehicles. In the center is obviously the GMC Hummer EV. On either side of it are Cadillacs. To the left seems to be the Lyriq crossover, and to the right is the Celestiq sedan. Two of these cars have production dates, and the third has been confirmed for eventual production, just without timing. This is why we think the rest of the cars are upcoming models. The next most easily identified car is on the near right behind the Cadillac Celestiq. It very clearly has a Chevy bowtie illuminated in the running lights. And looking closely, it appears to be a pickup truck. It's difficult to make out anything more than that. The nose does look a bit more rounded and swept back than the brick-like designs of the Silverado truck line. That also squares with what seemed to be the upcoming truck that appeared in the background of yet another GM presentation. GM previously said this electric Chevy truck will be a full-size model with up to 400 miles of range. That leaves us with three more mysterious models. Over to the left behind the Cadillac Lyriq are what appear to be a pair of crossovers. The one on the far left looks low, curvy, and possibly with a fastback roof. The one on the right is taller, boxier, and probably more of a full-size people hauler. It's hard to say much more beyond that. They could be new electric Buicks, which would fit in nicely with that brand's crossover portfolio, and would likely be highly successful in China, where Buicks, crossovers and electric cars are all rather hot commodities. As for the mystery car on the far right, it's quite a puzzle. We can at least rule out Buick and Cadillac, and GMC since it's definitely a car, and a rather small one compared with the other cars on display. That leaves Chevy, and possibly the autonomous division Cruise. We're leaning toward it being a Chevy, since the first Cruise vehicle is going to be a boxy pod of sorts.
