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.

Biden's tariffs likely won't impact Americans already driving Chinese-built cars

A 2024 Buick Envision Sport TouringGM-DESIGN Chinese car brands are missing from the US market, but Chinese-made cars are still sold in the US.  Americans bought more than 104,000 Chinese-made cars in 2023 and nearly 28,000 in Q1 2024. Buick, Lincoln, Polestar, and Volvo all sell cars in the US that are made in China.  Of the more than 15 million cars sold in the US last year, none wore the badge of a Chinese car brand. Chinese EV heavy hitters like BYD and SAIC are conspicuously missing from US showrooms. With the government's existing 27.5% tariffs on Chinese-made cars and Tuesday's new 100% tariffs on Chinese-made EVs imported to the US, the situation isn't likely to change anytime soon. What some people might not realize, however, is that tens of thousands of cars manufactured in China are sold in the US every year. Volvo's S60L sedan was one of the first Chinese-made cars to be sold in the US starting in 2016, followed by Buick's Envision SUV and Cadillac's CT6 Hybrid. According to Automotive News data, US consumers purchased more than 104,000 Chinese-made vehicles in 2023, up 45% from 2022. Americans bought another 28,000 Chinese-made cars during the first quarter of 2024. Currently, Buick, Lincoln, Polestar, and Volvo sell Chinese-made vehicles in the US. Of those, the only Chinese-made EVs come from Polestar, a brand co-owned by Volvo and its parent company, Geely Automotive. The EV brand imported just 2,217 cars in the first three months of 2024. It is unclear how the new tariffs will affect Polestar's future production plans. The company eventually plans to move some of its car production to South Carolina in 2024. In a statement to Business Insider, a Polestar spokesperson said the company is evaluating the Biden Administration's announcement. Here's a closer look at the Chinese-made cars on sale in the US. Buick Envision A 2024 Buick Envision AvenirGM When it launched in 2016, the Buick Envision compact SUV was one of the first Chinese-made vehicles sold in the US. The second generation Envision, which arrived in 2021, continues to be made in China at one of the plants GM operates in a joint venture with SAIC. The Envision was Buick's second-best-selling model in 2023, with more than 44,000 vehicles sold. Last year, Buick sold 167,000 vehicles across its entire lineup in the US, an impressive 61% increase over the previous year. However, this number pales in comparison to Buick's sales in China, which totaled 517,000 units last year.

2022 Buick Enclave revealed with refreshed styling, more standard features

Buick gave us a sneak peak at the 2022 Enclave back in January, but it officially pulled the sheet back Wednesday to reveal the extent of its updated styling and detail a few updates to its feature content, including a new suite of standard safety tech.  We can now better see the various exterior styling touch-ups, including a larger, more pronounced grille, new head- and taillights, and more angularly sculpted front and rear bumpers. The Avenir's exterior treatment was also updated to incorporate the new elements. The changes aren't too dramatic, but Buick did enough to make the 2022 visually distinguishable from previous years.  The new standard safety suite is Buick's Driver Confidence Plus package. It includes automatic emergency braking with pedestrian detection, lane keeping assist with lane departure warning, blind spot monitoring, forward collision warning, rear park assist, rear cross-traffic alert and automatic high-beams. Buick's midsize crossover is still powered by a standard 310-horsepower V6 with optional all-wheel drive. The range-topping Avenir model includes an adaptive suspension and unique styling elements.  Despite our previous expectations, the Enclave's cabin didn't really get an upgrade apart from the standard safety items listed above. Buick did not include pricing information in Wednesday's announcement, so you can look forward to yet another update before the 2022 Enclave goes on sale later this year.  Related video: 2021 Buick Envision Running Footage
