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.

Last-ever Buick Grand National heads to Barrett-Jackson auction

This 1987 Buick Grand National brought the curtains down on a heap of General Motors history. When this black beauty rolled down the line at 5 p.m. on December 11, 1987, it represented the end of manufacturing at GM's Pontiac Assembly Plant after 60 years building cars. This was the last car to sit on GM's G-Body platform, having supported legendary names like Monte Carlo, Cutlass Supreme, and Regal. And this was the last-ever Buick Grand National, a big coupe that in just five years on the market had helped make the Buick Regal lineup an object of sincere lust among enthusiasts. Powered by a 3.8-liter turbocharged and intercooled 3.8-liter V6, the engine made 245 horsepower and 355 pound-feet of torque. The only car above it in the lineup was the exceptionally rare GNX, which made 276 hp and 360 lb-ft. The Buick Grand National is headed to the Barrett-Jackson auction block in Scottsdale next month.    Louisiana resident Bob Colvin bought this car from the factory. The Drive spoke to Colvin, who explained that then-GM President Roger Smith told him he could have the penultimate Grand National, but Buick planned to put the last car on display. When Colvin arrived at the plant, though, Colvin said the plant manager told him, "I'm running this plant and you've gone through the effort to be here. It will be a real celebration," and got him the last car made. As proof, a GM film crew followed the car down the line, plant workers and two GM execs signed various parts of the engine, including current GM President Mark Reuss. The car comes with all of the autographs and signage the autoworkers created to go with the car, as well as the original window sticker. Colvin and his wife built an addition onto their house to display the car. Save for a trip to the Buick Centennial Celebration in 2003, the Buick has lived in its special place all its life and has just 33 miles on the odometer. Behind the new-car plastic that shrouds the interior, the only flaw appears to be a tiny crack in the steering wheel center cap where a bolt might have been overtorqued. The car is being offered with no reserve, the pre-sale estimate landing right around the $500,000 mark. That would about double recent auction sales for low-mileage GNX's this year, but there's every reason to believe this car's one-of-one place in history could get auction paddles waving. 

May 2016: FCA wins, Ford and GM stumble on weak car volumes

The May 2016 sales numbers are in, and it looks as though FCA is getting some vindication for boldly cancelling two slow-selling car models. Meanwhile, Ford saw overall sales dip and GM's May volume took a big dive versus the same month in 2015. While Marchionne's decision to axe the Chrysler 200 and Dodge Dart has drawn criticism as being short-sighted, it's working for FCA so far. Although the Dart and 200 aren't out of production yet and no capacity has been shifted to crossover or trucks, May's numbers show that the emphasis on Jeep and Ram models makes sense right now. FCA's US sales rose 1 percent last month compared to May 2015, putting the year-to-date total at 955,186 vehicles, an increase of 6 percent compared to the same period last year. Standouts included the Jeep Renegade, Compass, and Patriot, and the Fiat 500X. Ram pickup sales were down 3 percent. And your fun fact is that Alfa Romeo sales were up precisely 10 percent, for a total of 44 4Cs sold versus 40 in the same month last year. At FoMoCo, the Ford brand took a hit to the tune of 6.4 percent from May 2015 to 2016, registering 226,190 sales last month. Lincoln showed improvement on its modest numbers, going from 9,174 to 9,807, a 6.9 percent increase. Overall, Ford was down 5.9 percent for the month to 235,997; despite the slump, year-to-date total Ford sales are up 4.2 percent to 1,112,939. Strong sellers included Escape, Expedition, F-Series, and Transit - big stuff. Most small and/or efficient models (Fiesta, Focus, Fusion, C-Max) saw sales slides. Fusion sales were also down, likely due to effects of model changeover to the freshened 2017 model. Ford has promised four new crossovers and SUVs by 2020 and if things keep trending this way the company will be able to sell them, but things could change in the next four years. GM saw the worst of it for domestic brands. Retail and fleet sales were down for each of the four divisions, with the May 2016 total dropping 18 percent to 240,450 vehicles. GM's year-to-date sales are down 5.0 percent in 2016 to 1,183,705. Both the Sierra and Silverado were down significantly, and the majority of Chevy, Buick, GMC, and Cadillac nameplates saw sales decreases, with both small cars and larger utilities included. Not even big stuff could help GM this month, it seems. We'll have more on the rest of the industry's May sales as those figures trickle in.
