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.

1987 Buick Grand National was made to be Kevin Hart's 'Dark Knight'

The Meguiar's booth at the SEMA show isn't the only place comedian and actor Kevin Hart is combining cars and cinema, his "Michael Myers" 1969 Plymouth Road Runner brooding in the car care products pen, while his SpeedKore "Hellraiser" 1970 Dodge Charger also menaces. Hart bought a 1987 Buick GNX last year and put it on Instagram with the caption, "Sundays are perfect for old school drives…. If you know you know." Looks like old G-Bodies are perfect for restomod builds, too, which we all already knew, but this car isn't the GNX that featured on social media. This is the 1987 Buick Grand National, one step below the GNX and half the price at the time. It's nicknamed "Dark Knight" and it's one of the stars of the Magnaflow exhaust booth at SEMA. Going back to work with regular collaborators Dave Salvaggio of Salvaggio Design and Sean Smith, of course there's a lot involved in the overhaul. Still, we appreciate how the team stayed true to the ethos of the Grand National in ways that made the build more complicated than it already was. Take the engine. The original came with a 3.8-liter V6 wearing a single turbocharger to register an official output of 245 horsepower and 355 pound-feet of torque compared to the GNX's 276 hp and 320 lb-ft. Instead of swapping it for a V8, it's been replaced with the 3.6-liter twin-turbo V6 from the Cadillac CT4-V Blackwing. And instead of leaving both turbos on, the engine junkies plumbed a single turbo in a layout recalling the 1987 engine even as it cleans up the original Chutes 'n' Ladders mess of tubes. We didn't get an output rating for the setup. The Cadillac's twin-turbo mill makes 472 hp and 445 lb-ft. in the CT4-V Blackwing. We would bet Dark Knight's engine's pretty close to that with the single large turbo at the prow, plenty of juice for a car weighing 3,545 pounds. Exterior upgrades include a custom front fascia with a carbon fiber hood and splitter. The interior shows the same tasteful restraint, polished design and nicer materials draped over the stock 1980s layout. That shifter controls GM's 8L90 eight-speed automatic instead of the original four-speed auto.  Elsewhere, Salvaggio did the same here as with the Michael Myers Road Runner, creating a custom frame to increase rigidity and get the car closer to the ground on its 19-inch HRE wheels in the Buick's original weave look.

Buick celebrates 110 years by naming most significant model of each decade

In May of 1903, Buick began work on its first vehicle, the 1904 Model B, the first example of which was sold to a doctor in Flint, Michigan. That first sale was appropriate since later on, Buick became known as a "doctor's car." The Model B is the first of 11 cars chosen by Buick to highlight each decade of the company's 110-year history.
The 1916 D-45 Touring with a six-cylinder engine was Buick's highest seller that year, and helped push overall sales past six figures for the first time, making Buick the top-selling automotive brand. In 1931, Series 50 got an eight-cylinder engine, which helped the company survive the Great Depression. The 1936 Century was the first Buick that could hit 100 miles per hour, the 1949 Roadmaster had a supporting role in Rain Man, the 1953 Skylark had Italian wire wheels and the owner's name engraved on its steering wheel.
Then we have the iconic 1963 Riviera, the V6-powered 1975 Regal, and in 1987, the legendary GNX. With a turbocharged, intercooled V6 pumping out 276-horsepower it could hit 60 mph in just 4.6 seconds. In 1999 Buick built the first car in China, the Century, and that country remains the brand's largest market.
