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.

2013 Buick Encore nets strong IIHS, NHTSA safety scores

After being crushed from every which way and rolled over like a labrador, the 2013 Buick Encore has been named a Top Safety Pick by the Insurance Institute for Highway Safety. To earn the accolade, a vehicle must achieve the highest rating of "Good" in each of the institute's four main crash tests: Front Moderate Overlap, Side, Rollover and Rear. The Encore aced those four tests with "Good" ratings, but missed out on the coveted Top Safety Pick+ designation by receiving a Poor rating in the institute's new Front Small Overlap test. To be named a Top Safety Pick+, the Encore would need to score at least an "Acceptable" rating in the new test, as well as "Good" in all four original crash tests.
Despite the miss, the Encore joins the Enclave, LaCrosse, Verano and Regal as Top Safety Picks all. If you count only the Encore with all-wheel drive, then all five Buicks have also earned five-star overall ratings from the National Highway Traffic Safety Adminstration, making Buick one of the few manufacturers to offer a full lineup with high scores from both safety rating organizations.
The front-wheel-drive Encore, despite performing equally as well as the all-wheel-drive version in NHTSA's crash tests, only earned four stars overall. As far as we can tell, the discrepancy between the two is because some safety equipment, like Forward Collision Warning and Lane Departure Assist, are optional features on the FWD Encore and standard on the AWD model.

38k GM eAssist hybrids recalled for circuit board, fire risk

General Motors has issued a recall covering 38,197 2012 and 2013 model-year Chevy Malibu Eco, Buick LaCrosse and Regal sedans equipped with eAssist, and sold in the United States. The automaker will check the generator control module for proper operation. Only vehicles built before December 2012 are being recalled.
According to the automaker, a malfunctioning generator control module could slowly drain the battery, causing an indicator to light up in the dash. If that indicator is ignored, the driver may experience a stalling engine, and in some cases, "a burning or melting odor, smoke, and, in rare instances, a fire in the trunk."
GM says the issue is not with the eAssist battery pack; the smoke and fire comes from overheating of the control board. One trunk fire has been reported, but no injuries are known. Scroll down below for the official press release from GM.
