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.

GM's Flagship Lambda Is (Still) A Smooth Operator
Consumers shopping for a domestic full-size crossover have heard all about GM's triplets. The Chevrolet Traverse, GMC Acadia and Buick Enclave are a very appealing and talented group of siblings. Entering their fifth year of production, albeit middle-age in the automotive industry, each is attractive, well-rounded and very capable on the paved dance floor. While all share nearly identical base DNA and the same basic running gear, subtle physical differences and unique personalities emerge between the trio when one digs a bit deeper.
The most polished of the threesome, without question, is the Enclave from Buick. Fresh off a mid-cycle update (as are its siblings), the flagship of the platform boasts a facelift, innovative new features and an upgraded demeanor for the new model year.

Buick to kill Verano as early as 2017

The Buick Verano's days are allegedly numbered. Citing unnamed sources, Automotive News is reporting that Buick will kill its Delta-platform-based sedan. The company offered the typical "no comment." According to AN, Buick is expecting 70 percent of its sales to come from the Encore, Envision, and Enclave once the Envision goes on sale. And it doesn't take a professor of economics to recognize that when half the vehicles you build account for just 30 percent of the sales, it's time to trim. But the case for killing the Verano is a weird one, because the problem isn't a lack of demand. Struggling sales might be the reason to kill a car, but the Verano is – and has consistently been – Buick's second best-selling sedan. It's beaten the slightly larger, more expensive Regal by at least 12,000 units in each of the last four years. Hell, in 2013, Buick sold 45,000 Veranos to fewer than 19,000 Regals. So why not kill the Regal? Well, the Verano's raison d'etre is irrelevant today. Buick launched its smallest sedan at a time when premium compact four-doors weren't a thing and gas prices were high enough that consumers were still hesitant to tie themselves to a CUV's fuel bill. And while it was roughly the same size as the Chevrolet Cruze that it shared GM's Delta platform with, it had enough unique equipment to stand apart and warrant its price premium. Today, fuel prices are cheap and consumers are flocking to crossovers while Buick is stuck sharing the premium compact pie with much more prestigious names ( Mercedes-Benz and Audi). And because it's sharing showroom space with the super-popular Encore, even the Verano's affordable pricing has become a liability. Today, a lightly equipped Verano is the same price as a base Encore, and they offer broadly similar features (rear-view cameras, a seven-inch touchscreen with Intellilink, Bluetooth, etc.). And if the Encore is too small, there's probably a GMC Terrain sitting in the same showroom, offering more utility and equal equipment to the Verano for a similar price. As one dealer told AN, "For not much more money, customers can get an SUV." Killing the Verano might risk 30,000 to 40,000 sales, but it's a move that proves Buick has tremendous confidence in its CUV lineup – clearly the company thinks the Encore can do the job of luring customers into showrooms. AN's sources claim the Verano will survive through 2017, so we'll be waiting a few years to find out if that faith is misplaced. Related Video:
