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.

Next Buick Regal coming in 2017, could be imported from Germany

The Buick Regal is based on the Opel/Vauxhall Insignia, a pair of sedans from General Motors' European and British outfits. In fact, over 46,000 Regals from model years 2010 and 2011 were screwed together on the same lines as the Insignia twins, before GM's Oshawa, Ontario factory took over production fully. Considering this closeness, rumors that claim the next-generation Regal - due for 2017 - could move back to Europe aren't terribly surprising. Here's why, according to Automotive News.
Oshawa is home to three other vehicles, aside from the Regal - the Chevrolet Camaro, Impala rental queen and the Cadillac XTS. We already know next-gen Camaro production is headed to Lansing, MI, and that the fleet-only Impala will (finally!) die in 2016. As for the XTS, as AN explains it, sales are so slow that GM will either kill it or just shuffle its production volume elsewhere.
Taken along with the fact that Unifor, the Canadian labor union repping workers at the Oshawa factory, claim GM hasn't made any guarantees about future production at the nearly 60-year-old factory, it seems fairly clear that the Regal's current factory is going to be put out to pasture.

As GM readies Alexa convenience for vehicles, we ponder its dark side

SEATTLE — On the 30th floor of AmazonÂ’s glass tower, in a room with a breathtaking view of downtown Seattle, thereÂ’s a beautiful bed that nobody sleeps in. ItÂ’s near a kitchen nobody cooks in, a living room couch that no one crashes on, a kitchen table that doesnÂ’t host any family meetings. ItÂ’s AmazonÂ’s Smart Home Lab, a place where every Alexa-enabled gizmo the company or its partners can produce is crammed into the same space, ostensibly for Amazon to test. The company invited us there to show us the companyÂ’s vision for consumer products to leverage AlexaÂ’s voice interaction software before taking us down to a demo of its latest implementation in a Buick Encore GX. In this eerie simulacrum of a fantastic luxury apartment, however, nothing went right the first time. ItÂ’s a challenging environment for Alexa to work correctly, our hosts noted, pointing to the fact that there were six wifi networks available for the devices to connect to. In a normal home, one wifi network controls all the devices, who can theoretically sort out for themselves which one youÂ’re actually trying to activate. In the Smart Home Lab, any unmuted Alexa device thinks itÂ’s in charge. Even so, the connected toaster wouldnÂ’t connect. The Fire TV Cube wouldnÂ’t play a song. Our handlers futzed with everything, muting and unmuting devices, repeating commands, making us feel better about our own struggles with similar technologies. If it doesnÂ’t work right at Amazon HQ, maybe itÂ’s not just us! ItÂ’s telling that down on the faux lawn, in between the gleaming Amazon spheres that host a billionaireÂ’s tropical garden and the Day 1 building that the Smart Home Lab resides in, the BuickÂ’s Alexa implementation doesnÂ’t use a “wake-word” at all. The familiar Push to Talk button on the steering wheel, which normally activates General MotorÂ’s own proprietary voice command system, can be set to default to Alexa when that rolls out to GM vehicles in the first half of 2020 via an over-the-air (OTA) update. Given the reluctance of Alexa to respond to its wake-word in the comfort of AmazonÂ’s own lab, we hoped that this was by design. Drivers are already familiar with Push to Talk, and a physical button is more reliable than the vagaries of contemporary voice recognition – not to mention the privacy and accuracy issues involved with always-on mics. Our experience with the not-ready-for-primetime Mercedes-Benz MBUX system is illustrative.
