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.

Buick shows off Wildcat EV in gold, debuts new brand tagline

Buick keeps putting the gorgeous Wildcat EV concept back in front of our faces, and it’s just not fair. GMÂ’s premium brand released a new tagline today, “Exceptional by design,” and the Wildcat EV is the face of the companyÂ’s new motto. Check out the video above to see what all the fuss is about. There are a lot of glamor shots showing beautiful Buicks of the past before it cuts to the also-glamorous Wildcat EV concept. ThereÂ’s even a shot of a slight variation of the Wildcat EV dipped in a flashy orange-gold paint color. GM showed off this version of the Wildcat EV in an Instagram post last year, but now weÂ’re seeing the electric two-door coupe in yet another promotional piece. It differs from the final show car in its grille design, headlights, wheels, badging, color and more. Take a look at the side-by-side comparison below. Of course, Buick doesnÂ’t actually make products nearly as exciting as the Wildcat EV, but it does like to show its Encore GX and Envista sharing some design elements with the Wildcat EVÂ’s front end. A jump cut to those crossovers quickly follows our glimpse of the colorful Wildcat EV, though we canÂ’t help but be a little sad that this is all that will come of the stunning concept. Per usual (at least when we get the chance), we asked Buick if it had any updates or things to share about the Wildcat EV now that itÂ’s trotting this concept out to us in a brand campaign. HereÂ’s what the company had to say in response: "The Wildcat EV concept is still our blueprint for Buick design and youÂ’ll see Wildcat inspiration throughout our lineup, starting with the current Encore GX and Envista, and it will eventually extend to the 24MY Envision and 25MY Enclave. We still donÂ’t have any plans to bring that vehicle into production, itÂ’s strictly a concept." Basically, nothing's changed, and there are still no plans to turn the Wildcat EV into a production car. There wasnÂ’t much in the way of news today from Buick, but we can at least say this latest ad campaign is a clear step up over the “ThatÂ’s not a Buick” commercials seen years ago. Related video:

2020 Buick LaCrosse images leaked on Chinese website

Buick is planning a refreshed version of its LaCrosse full-size sedan for the Chinese market, judging by these photos discovered by the site Auto Verdict on a Chinese government site used to certify upcoming new models. We can only see exterior cosmetic changes, but they bring the LaCrosse more in line with the styling of the new Regal and Enclave models, leading to speculation that it won't be long until the changes show up in the U.S. The front three-quarters photo shows off a redesigned front fascia, with slimmed-down headlights that are now tied to the grille instead of set apart by body-color surround, thanks to some new chrome treatment. There's also a chrome wing on the grille, similar to what's seen on the 2019 Enclave and new Regal. The lower front fascia is also different, with new L-shaped fog lamps. On the rear, there's a new chrome wing connecting and intersecting the taillights and surrounding the badge. There's no word about any interior changes, but they'd likely be minor in keeping with the exterior updates. Buick most recently debuted a 2019 LaCrosse Sport Touring version, while a mild hybrid model arrived for 2018. China, of course, has become Buick's largest market, but the picture is less rosy stateside amid dimming prospects for sedans, as consumers flock to crossovers and SUVs. In the third quarter, U.S. sales of the LaCrosse fell 31.1 percent from the prior-year period. Between January and the end of September, GM had sold 13,409, which was a decline of 14.2 percent. Its full-year 2017 sales totaled 20,161, which was down almost 27 percent from 2016. For perspective, Buick sold more than twice that number — 42,035 — as recently as 2015. The current generation launched in 2017. Related Video: Featured Gallery 2020 Buick LaCrosse China Image Credit: Buick Design/Style Buick Luxury Sedan
