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 expanding Lansing Lambda CUV plant

Considering that crossovers are a rapidly growing portion of the US auto market, it's not surprising to hear that General Motors is preparing to build even more of them. The company is investing $63 million to expand its Lansing Delta Township Assembly plant that builds Lambda platform CUVs like the Chevrolet Traverse, GMC Acadia and Buick Enclave.
According to GM, the expansion will add roughly 263,000 extra square feet of space to the plant. Of that, 181,000 square feet will be for an updated body shop with cutting-edge robots. There will also be 54,000 square feet of additional room in the paint shop and 28,000 square feet of more area for general assembly.
GM isn't saying as much, but there is the possibility that this extra space could allow for additional models produced at the factory. Cadillac reportedly dropped plans to build a three-row SUV on the Lambda platform earlier this year, however, dealers for the luxury brand were recently pitched the possibility of adding large and small CUVs, an ATS convertible or a sedan below the ATS.

1987 Buick Regal GNX driven just 54.8 miles heads to auction

The previously unimaginable prices for seemingly anything on any number of wheels continues to lure garage queens into the open. Here we have another Buick GNX headed to auction, this one Mecum's Summer Special in Orlando from July 6-9. Buick only made 547; it feels like half went to owners who never drove them. The last GNX auction we covered, in 2019 on Bring a Trailer, ended up grossing $200,000 for a model with 8.5 miles. This example has been driven much harder than that, praise be to enthusiasts, with 54.8 miles on the odometer. That means the original owner, who kept the coupe until 2017, got more than six times the use out of his GNX than the 2019 owner. Way to go. For those who haven't attended any classes on the Buick Regal GNX, allow us to summarize the subject matter. When Buick greenlit "a Grand National to end all Grand Nationals," out came the one-year-only 1987 GNX. A racier brand back then, it partnered with ASC/McLaren to work up the wheel lip flares, fender vents, 16-by-8-inch BBS rims, more aggressive tires, and the interior treatment. The Grand National trim used a 3.8-liter V6 making 245 horsepower and 355 pound-feet of torque hooked to a four-speed automatic. The GNX benefited from a larger Garrett T-3 turbocharger with a ceramic impeller, a larger intercooler, more aggressive fuel, spark, and waste gate tables, and a dual exhaust system that boosted output to what some say is an underrated 276 hp and 360 lb-ft.  This GNX headed to auction spices up the standard specs with the original order paperwork, window sticker, dealer invoice, ASC documentation, a GNX coffee table book, and a GNX jacket. That jacket could be the denim one or the high school varsity jacket with the cloth front and back and leather(ish) sleeves, which, sadly, didn't include Buick's attacking eagle logo of the time. We'd mention the black and sand gray cloth interior, power driver's seat and mirrors, and Delco Concert Sound stereo, but it's likely that the future owner won't spend much time with them. Likely fated to be a garage or show queen again, the jet black paint, "original parts stickers still affixed on suspension," and "original chalk markings throughout" will be the major points of interest. Mecum doesn't give a pre-sale estimate for this GNX, so we'll be waiting to find out if the 2019 sale price was an anomaly — well, more of an anomaly — or the new benchmark.
