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 announces net 220 job increase as Trump visits Michigan

GM announced today that about 900 jobs would be added (or, importantly, retained) ahead of President Trump's arrival in Michigan, where he is expected to discuss his plan to roll back fuel economy standards. The timing of the announcement is almost certainly not coincidental, as appending it to a Trump visit gives it a higher profile and dovetails with the President's jobs agenda. It's less likely the decision itself was made for those reasons, but the free PR boost is a nice bonus. As for those 900 jobs themselves, they aren't all new jobs. The only net gain is approximately 220 jobs at the Romulus Powertrain Plant, which produces the 10-speed automatic transmission that's proliferating through the company's lineup. The 180 jobs at Flint Assembly and 500 jobs at Lansing Delta Township are retained jobs – that is to say, spots the company found for workers who would otherwise have been laid off. By the way, the Flint jobs will help with production of heavy-duty pickups, and the Lansing jobs are to produce the Chevrolet Traverse and Buick Enclave. Finding jobs for manufacturing workers in the auto sector, whether new or retained, is admirable. No matter how GM couches it, the company has created or retained a total of 7,000 jobs this year, and its total reinvestment in US production is around $1 billion. But these decisions are business ones, not political ones – timing the announcements to make them seem inspired by economic policy, or the political situation, is simply smart PR.

Buick Cascada dies the death everyone expected

Four months ago, the Grim Reaper came for the Opel Cascada. Groupe PSA, which bought Opel from General Motors in 2017, announced the two-door convertible would be phased out. On sale here since 2016 as the Buick Cascada, GM told us it had nothing to say about PSA's announcement. On Friday, the U.S. automaker spoke up, telling Automotive News the droptop "has reached the end of its originally-planned lifecycle and 2019 will be the last model year offered. Dealers have been notified and many will have stock through the rest of this year." Buick paid big money to advertise its first convertible since the 1991 Reatta. Buick threw money at Super Bowls ads and a gaggle of celebrities two years in a row. And when sales began in 2016, Buick enlisted The Unbreakable Kimmy Schmidt star Ellie Kemper for a series of television and online spots. U.S. dealers have been instructed to file final orders this month, and production will continue at the factory in Poland until this summer. Yet the fact we're in February and dealers are predicted to have stock for the next ten months says everything necessary about the state of play. The brand sold roughly 17,000 units in three years, and both 2017 and 2018 saw sales declines of more than 25 percent. Buick didn't expect huge sales from the import, though, and the Cascada earned conquest buyers. A spokesman said, "The Cascada has played its role in the portfolio perfectly, outselling many other premium convertibles while bringing in [6 of every 10] buyers from outside GM." Last we heard, the LaCrosse ceases production next month. Unless the situation changes before the end of the year, Buick will have only the Regal on its passenger car books come 2020. GM will only have two convertibles in its portfolio worldwide, the Chevrolet Camaro and Corvette. Related Video:
