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 will cease using ‘Buick’ badge on vehicles from 2019

GM Authority recognized that the recently unveiled 2019 Buick Envision is missing something: a " Buick" badge on the left side of the tailgate. Every other vehicle the carmaker sells features that script, but not the new mid-sized crossover. When the site asked about the omission, "representatives recently told GM Authority that Buick will stop using the brand badge on the rear of its vehicles, starting with the 2019 model year." The only identifiers that will remain are the three-color Tri Shield logo and the model nameplate, i.e., "Envision" or " Regal." It's a bold game for a mass-market major automaker, though Audi, Hyundai and Volkswagen follow the same trend. Even Bugatti, Rolls-Royce, Bentley, and Aston Martin affix their brand names to their vehicles within company icons or on brake calipers, albeit in small fonts. The coming Continental will wear the word "Bentley" across its trunk, silverware the present Continental does without. Porsche allows customers to delete model designations, but it must be requested. At the other end of the spectrum, the Ford Mustang Bullitt wears zero badges, but the Bullitt is a special edition of a well known model that otherwise advertises its provenance everywhere. Buick plays in hard-fought segments where mass appeal overrules instantly-identifiable design daring. Those kinds of carmakers usually want to take every opportunity to advertise every sale. Remember the last Buick to go without a make badge? The terrifically handsome Buick Avista concept that wore only two Tri Shield logos and its model name on the decklid. Perhaps that gave Buick some ideas. If the carmaker plans to start putting out cars like the Avista, then this move makes perfect sense. Update: A commenter pointed out that Hyundai vehicles don't have "Hyundai" badges, only the "Flying H." We've thought of some other brands/models, too. So Buick has mass-market company.

Buick dusting off Grand National, GNX and T-Type nameplates

Inside Line reports Buick is planning to bring back some of the more storied names from the company's past, including the Grand National, GNX and the T-Type. Those cars rose to prominence in the 1970s and '80s to become performance legends of their day.
The new models will reportedly make use of the rear-wheel drive platform that currently underpins the Cadillac ATS and all would arrive as sedans - according to an unnamed source familiar with the initiative. Odds are the T-Type and the Grand National would share a driveline, with honest money being on a new twin-turbocharged 3.6-liter V6 as the engine of choice. Word has it the mill will be good for anywhere from 350 to 400 horsepower.
That leaves only the GNX. Inside Line seems to think that machine could get down the road with some help from the all-new GM LT1 small-block V8. The engineers behind the ATS platform have already told us the engine bay is large enough for to accommodate the big eight pot, and since GM is most certainly working on an ATS-V, a slightly less powerful, less luxurious Buick iteration makes some kind of sense. We can't wait to see these things in the light of day.
