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.

2013 Buick Encore nets strong IIHS, NHTSA safety scores

After being crushed from every which way and rolled over like a labrador, the 2013 Buick Encore has been named a Top Safety Pick by the Insurance Institute for Highway Safety. To earn the accolade, a vehicle must achieve the highest rating of "Good" in each of the institute's four main crash tests: Front Moderate Overlap, Side, Rollover and Rear. The Encore aced those four tests with "Good" ratings, but missed out on the coveted Top Safety Pick+ designation by receiving a Poor rating in the institute's new Front Small Overlap test. To be named a Top Safety Pick+, the Encore would need to score at least an "Acceptable" rating in the new test, as well as "Good" in all four original crash tests.
Despite the miss, the Encore joins the Enclave, LaCrosse, Verano and Regal as Top Safety Picks all. If you count only the Encore with all-wheel drive, then all five Buicks have also earned five-star overall ratings from the National Highway Traffic Safety Adminstration, making Buick one of the few manufacturers to offer a full lineup with high scores from both safety rating organizations.
The front-wheel-drive Encore, despite performing equally as well as the all-wheel-drive version in NHTSA's crash tests, only earned four stars overall. As far as we can tell, the discrepancy between the two is because some safety equipment, like Forward Collision Warning and Lane Departure Assist, are optional features on the FWD Encore and standard on the AWD model.

2019 Buick Envision First Drive Review | Still not a standout

ATLANTA – "We're in the fashion business," executive chief engineer Rick Spina told us as he introduced the 2019 Buick Envision. "Except with a lot of technology." Spina was referring to the changing whims of new-car buyers, which have prompted Buick to give the compact Envision crossover its mid-generational update early — just 18 months into its lifecycle — and drop its prices across all trim levels. As with much of our consumer goods, the Envision is made in China. That doesn't seem to have hurt it in the market, even though it wears the badge of one of the most quintessentially American brands out there. It even aced the IIHS crash tests, putting it in league with Volvo, Mercedes-Benz and Lexus. There's good news and bad news about how the Envision is doing. It's now the third-best-selling model in the Buick portfolio, behind the three-row Enclave in second place and the surprise hit Encore subcompact crossover in first. Sam Russell, Buick's director of marketing, reported 73 percent growth in the past nine months versus the first half of its market life. A full 60 percent of Envision buyers are new to the GM family, too, and Russell says that nearly half of those are likely to buy another Buick SUV when the time comes to trade in the Envision. And yet, the Envision trails in luxury compact-crossover sales, behind mainstays such as the Audi Q5 and Acura RDX, even amid crossover demand in the U.S. that has companies like Nissan posting record sales numbers and Ford canceling a redesign of the Fusion. Our test of the 2017 Envision found it competent, but lacking that "X factor" that would send buyers of German and Japanese marques flocking. Instead, we compared it to the Jeep Grand Cherokee and Hyundai Santa Fe Sport, and deemed those both better values. Perhaps Buick feels the same, because the base 2019 Envision now starts at $32,990, a $2,000 cut from last year. The Preferred trim level sees a greater drop of $2,400, to $34,495. Rounding out the naturally aspirated 2.5-liter grades, the Essence's price falls $1,900 to $36,795. The turbocharged 2.0-liter Premium and Premium II trims get a discount of $1,600 and $1,400, respectively. With those prices come changes that Buick hopes will make the Envision a more compelling prospect. Outwardly, the Envision sports a new grille, a winged affair to replace the 2018's waterfall and bring it in line with the rest of Buick's lineup.
