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.

Ford GT, Buick Avenir and Audi Q7 take 2015 EyesOn Design awards

The annual EyesOn Design Awards at the Detroit Auto Show allows some of the greatest designers in the world to weigh in on the best production and concept debuts at the big event each year. For 2015, the large panel of judges included luminaries like Frank Stephenson of McLaren, Ralph Gilles from FCA and Moray Callum of Ford. Apparently the editors at Autoblog had a good eye because the winner of 2015's Best Designed Production Vehicle award went to the Ford GT, which was also our favorite debut from the show. The new supercar beat the Acura NSX and Mercedes-Benz GLE-Class Coupe for the honor. The judges described the Blue Oval's shape as "capturing the original GT40 in a modern interpretation," according to EyesOn Design. The Buick Avenir was also a big winner in the awards this year and received the nods for both Best Designed Concept Vehicle and Innovative Use of Color, Graphics and Materials. In the concept category, it beat out the Chevrolet Bolt and Mercedes-Benz F 015, and in the latter group, the sedan triumphed over Audi Q7, Mercedes F 015 and Volkswagen Cross Coupe GTE. The Q7 received its own accolade for Best Designed Interior, and it beat the Avenir and Infiniti Q60 for the honor. This year's Lifetime Design Achievement Award went to former Renault designer Patrick le Quement, and Bob Lutz received the EyesOn Design Catalyst Award for the second time. The honor is for an executive "who has empowered great design," according to the organization, which describes Lutz perfectly.

New Buick Envision model spotted in China, expected here this year

At GM Capital Markets Day in February, GM North America president Barry Engle said the U.S. market can expect "updated models of Chevrolet Equinox and Traverse, Buick Envision and Enclave, as well as GMC Terrain." We've seen the Equinox and Traverse, and although we weren't aware, we've seen the Envision. Buick showed an EV crossover concept in 2018 called the Enspire, and it was thought to preview an eventual production model called the Enspire that's been spotted in various places testing under heavy camouflage in the U.S. GM, in fact, applied to trademark the Enspire name twice in the U.S. The model's final production form got an early reveal in China thanks to the Ministry of Industry and Information Technology, and according to GM Authority, a branding redirection has led to the crossover being called the Envision. Assuming this is the model that comes to the U.S., it will share dealer space with the current Envision imported from China. Motor1 writes that Chinese site Auto Home alleges the name Envision S will distinguish the new product, and the tailgate in the low-res photo plausibly shows an S after the model name. That doesn't mean it would get the S suffix here, though. It's not clear if the coming crossover grows in size compared to the standard Envision the way the Encore GX expanded a touch over the Encore. The marquee difference will be that the new Envision is more luxurious in looks, equipment, and features. There are few details, but it's thought the Envision S sits on the same E2 platform as the Cadillac XT4, and will use the same 2.0-liter turbocharged four-cylinder in the Cadillac paired with the automaker's nine-speed automatic. In the XT4, that mill produces 237 horsepower and 258 pound-feet of torque, but across all its applications in the GM stable it makes anywhere from 230 to 237 hp.    What we can see is that the new CUV takes the Envision name in a more dynamic direction, starting with a trim upper front fascia that puts narrow headlights astride a wide grille clearly derived from the concept, the lower front fascia with chrome-lined outer intakes that recall the Aston Martin DBX. A diffuser-looking silver trim piece in front is mirrored in back. A sloping roof helps create the slim profile, leading to a trim backlight, thin taillights, and strong horizontals on the bumper that emphasize width.
