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 Verano headed to Shanghai Motor Show

Buick is a big deal in China and ranks third in automotive brand popularity there, according to a recent poll. It should come as little surprise, then, that the company is using the upcoming Shanghai Motor Show to debut the next-gen version of the Verano. We are even getting a shadowy tease of the small sedan's look ahead of the April 19 unveiling. Actually called the Wei Lang in China, Buick says the redesigned Verano takes styling cues from the Riviera concept from 2013 Shanghai show and the recent Avenir, as well. Neither inspiration seems too obvious based on this teaser image, but the small sedan does gain two creases down its side: one arches through the front door handle and the other picks up over the rear fender. Buick isn't even hinting at what powers the Verano in China and simply asserts that the model sets class benchmarks for "performance, safety and comfort" there. Of course, as with many foreign market models, it's possible that the sedan could use different engines or wear different altered styling when it arrives in the US. Buick Verano Sports Sedan Named "Wei Lang" in Chinese, Will Make Debut in Shanghai on April 19 2015-04-14 SHANGHAI – Shanghai GM today announced that the Verano, Buick's new-generation sports sedan, has been given the name of "Wei Lang" in Chinese. It will make its debut in Shanghai on April 19, on the eve of Auto Shanghai 2015. As a new strategic model for the Buick brand, the Verano will offer a refreshing driving experience through its stylish and dynamic exterior, exquisite and comfortable interior, and precise and powerful performance. The Verano was inspired by the 2013 Buick Riviera concept car and captures the design essence of the Buick Avenir concept car, which debuted at this year's North American International Auto Show in Detroit. The Verano demonstrates Buick's insight into the aesthetic preferences of Chinese consumers. It embodies the innovative reimagining of Buick's classic design elements, exemplifying the elegance and dynamism of Buick's new-generation products. It is expected to set new benchmarks for performance, safety and comfort in its class. Like the all-new Excelle GT, which was launched earlier this year, the Verano will serve as a strategic model in Buick's bid for a stronger presence in China's mid-range vehicle segment. General Motors traces its roots back to 1908. GM has 11 joint ventures, two wholly owned foreign enterprises and more than 58,000 employees in China.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
