2018 Buick Enclave spied looking slim in Death Valley

The nine-year-old Buick Enclave is well past its prime, but this set of spy photos reveals that GM won't put the vehicle out of its misery, but will give the vehicle a large update instead. Our photographers managed to catch Buick testing a heavily-camouflaged 2018 Enclave testing below sea level near Death Valley. Buick was testing the prototype in Nevada earlier this year, but slapped a trailer onto the back of the SUV. Thanks to the camouflage that covers the badging, headlights, taillights, and hood, there's no way to confirm if the prototype is really a Buick or something from Chevrolet. But the circular outline on the grille has us leaning towards it being a Buick. Five LED running lights shine through the heavy camouflage, while Buick's iconic waterfall grille is prominently uncovered. The Enclave, which came out in 2008, shares the same platform as the GMC Acadia and Chevrolet Traverse. With the new Acadia slimming down and ditching the old Lambda platform in favor of the Chi platform, the Enclave will surely follow suit. The Enclave, though, is expected to get a stretched version of the Chi platform with three rows. While the entire body is concealed, the prototype's side profile looks to be slimmer than the current Enclave. With the addition of the new, lighter platform, the Enclave is expected to get GM's new 3.6-liter V6 with a nine-speed automatic transmission added later down the road. The new Enclave is expected to make its debut early next year as a 2018 model, which will be followed by the reveal of the Traverse shortly after.

Opel Cascada close to getting green light for US

For a company with a long tradition of grand touring convertibles, it's almost unseemly that General Motors doesn't offer a properly relaxed four-seat convertible in North America. There's the Chevrolet Camaro, of course, but it's not big on rear-seat space and it doesn't offer that sort of serene demeanor that many open-air buyers crave. We're thinking of something more refined and, dare we say, elegant. Something a bit closer to the Opel Cascada.
The General's front-wheel drive convertible went on sale in Europe this year, and while it seemed like a natural fit for its Buick brand in America, it's never been sold here. That may be about to change, however. Back in June, CEO Dan Akerson hinted he'd like to see the Cascada available in the US, and now there's word from Edmunds that importation "could happen soon." That's according to an unnamed insider at the company.

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.
