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.

Cadillac, Buick and Chevy decisions impacted by worries abroad

European Concerns Drive GM, But Beware Of The French Connection
GM's bid to rationalize Europe will impact the products that will be offered domestically.
It seems that Europe is defining the future of General Motors more so than its home North American market. Having axed Saturn, Pontiac and Hummer, GM has done a fairly good job of repositioning its remaining four divisions, Cadillac, Chevrolet, Buick and GMC. Cadillac carries the luxury banner. Chevrolet is aimed at the masses with cars and trucks along with a nod to performance thanks to Camaro and Corvette. Buick bridges the premium gap between Chevy and Cadillac, while GMC offers a hardcore work/upscale proposition.

Trademarks indicate Buick Regal wagon could be on the way

American wagon fans have been waiting for General Motors to import a Buick-badged version of the Opel Insignia Sports Tourer since the current Insignia-based Regal hit dealers. If a new patent filing is any indication, that day could be coming soon. Then again, it might not mean anything. AutoGuide reports that Buick has filed two trademarks with the US Patent and Trademark Office for "Motor land vehicles, namely automobiles." You can see the trademarks for "Tourx" and "Regal Tourx" here and here. "Tour" smacks of wagon models, while the "x" – for all-wheel drive – makes us wonder if maybe we'll be seeing a rebadged version of the high-riding Opel Insignia Country Tourer (shown above). This isn't the first time Buick has stoked the hopes of US wagon fans, though. Earlier this year, trademarks were filed for the "Regal Sport Touring," a name that's very close to the Euro-market wagon's title. In fact, that trademark had the same description as the Tourx/Regal Tourx filings. As we've established before, automakers file trademarks all the time. It's far from a guarantee that anything will come of such trademarked names. Still, two wagon-ish filings with the USPTO from Buick in under a year makes it seem like there's at least someone at the Trishield brand that's campaigning for a long-roof Regal. Fight the good fight, friend. Related Video:
