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 confirms 2017 Encore for New York Auto Show

Buick will unveil the refreshed 2017 Encore at the New York Auto Show in March, company spokesperson Stuart Fowle tells Autoblog. The brand isn't ready to divulge info about the updated compact crossover, but a recent revision to the Encore's European platform-mate, the Opel Mokka (above), might provide hints about what to expect. "While we have no additional details to announce, we're excited to confirm that media and customers will see the new 2017 Encore at next month's New York Auto Show. The Encore joins the Cascada convertible, Envision crossover, and LaCrosse sedan as the fourth new product arriving in Buick showrooms this year," Fowle said to Autoblog. Expect the 2017 Encore to have its own twist on the the Mokka's (now called the Mokka X) exterior styling, and spy shots hint the Buick has a new front end with a smaller grille. The Encore could benefit from the Opel's redesigned dashboard, which integrates the infotainment system into the center stack. It's a very attractive change, and we hope to see the switch in the US. The Mokka X also gets improved safety tech. The German compact CUV now sports adaptive LED headlights that adjust to traffic. US law doesn't allow these intelligent parts, but the Encore might get dumber LED lights. The Opel's improved front-mounted camera also increases the traffic sign detection rate. The Mokka X is available with the updated powertrain from the Encore Sport Touring, so there might not be any engine upgrades for the Buick. Buick needs to keep the Encore fresh, as the compact CUV is the brand's best selling model. It delivered 67,549 of them in 2015, a 38.2-percent jump over the previous year. The popularity continued into January 2016 with 4,920 deliveries – up 42 percent. Related Video:

Buick Envision crossover to premiere in China

Buick currently offers two crossovers: the compact Encore and the extra-large Enclave, leaving plenty of room to slot a mid-size crossover in between. And that's just what Buick is planning on doing. In China, anyway.
Previewed in the teaser above, Buick's upcoming new crossover is cloaked and nestled in between its aforementioned stablemates-to-be. Set to be unveiled in China sometime later this year, the model has been confirmed to wear the name Envision - at least in that market. That's the name which the concept version wore three years ago, but we're still waiting on word over whether that name will carry over to the US version or whether we should expect something different like Anthem. But we have to admit that Envision fits better in the brand's crossover naming scheme.
Shanghai GM isn't saying much about the Envision in the press release below, aside from it having "dynamic and assertive styling" backed by all-wheel drive and stop/start ignition. The last time Buick offered a mid-size crossover in North America was with the Pontiac Aztek-based Rendezvous that was discontinued seven years ago.
