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.

Opel Insignia, the harbinger of a Buick, rolls out at Geneva

GM's sale of Opel/Vauxhall to French automaker PSA Groupe will take effect later this year, but new models roll out regardless, as Opel debuted its all-new 2018 Insignia flagship (and Buick Regal clone) Tuesday at the Geneva Motor Show. The midsize Insignia, which bears a great resemblance to a Mazda6, will come in Grand Sport and Sports Tourer (that is, a wagon - will Buick offer a wagon?). It is built in Russelsheim, Germany. As part of the GM-PSA deal, the two companies agree that PSA, maker of Peugeot and Citroen, will continue to supply some Holden and Buick models; Opel models form the basis for several of Buick's core products, including the Encore small crossover and Regal sedan. But as the two brands part ways, we may well see Buicks remaining Buick-y, and Opels evolving away from GM parts and designs. Seeking a little clarity on what the sale of Opel means, we asked Buick and were directed to a statement: General Motors announced an historic agreement to sell the company's Opel business to PSA Group. This is a major milestone and one that we believe will improve the business prospects of each company and deliver significant value to shareholders, customers and employees around the world. Buick and Opel have historically cooperated on a number of product programs. Buick products will not be impacted by today's announcement. We will continue to deliver our product plans with excellence and precision. Buick has delivered three consecutive years of record global sales, we are General Motors' second largest international brand, and we have built an excellent reputation for quality and customer service. The new products Buick will announce in 2017 will help us build on this momentum. The new Regal/Insignia is expected to use the same platform as the new Buick LaCrosse, which is also shared by the Chevy Malibu and Impala. They should once again be available with front- or all-wheel drive. With the Opel versions debuting at Geneva, the Buick Regal will possibly follow at the New York auto show in April. The Insignia will start at about $25,500 and has the now-customary roster of high-tech options such as active lane keeping, a heads-up display, 360-degree-vew cameras, a hood designed to increase pedestrian safety and a new Opel OnStar Personal Assistant to help book hotel rooms on the fly or search for parking spots. The car comes with turbocharged four-cylinder engine options, an eight-speed automatic, and it's 400 pounds lighter than its predecessor.

The Chinese experiment | 2017 Buick Envision First Drive

The 2017 Buick Envision is a very good five-passenger crossover. The "but" you should anticipate will come in good time. First it's worth understanding why it exists at all. Out of the ashes of GM's bankruptcy a few flowers blossomed and the carmaker is doing exceptionally well, certainly far better than Chrysler has done in the wake of its free fall into Chapter 11. But of all the surprises at GM's turnaround, Buick surely ranks highest, without question the least likely player to thrive if you only study the North American market. Look farther than our shores, to China, however, and you won't be shocked. Note that the Envision, which has been on sale in China for a year and a half, will reach about 200,000 units this year; the entire Buick portfolio in the US only totaled 223,000 cars in 2015. Not only is China Buick's primary market, but what it makes there, like the Envision, is intended for a different sort of buyer. Here, we'd call it a compact crossover. In China the Envision is a relatively large car, and the buyer there is far more likely to use it as a tall limo, or at the very least, as a big-time status statement. That buyer is also very likely to be in his or her mid-30s – the average Buick buyer in the US is getting younger, but, at 58, is hardly a millennial. Still, Americans who buy the Envision will benefit from all of this China focus. Huge effort went into its development since the target competitor in China is the Audi Q5, according to Rick Spina, Executive Chief Engineer for the Envision. Spina explained that Buick went to the trouble and expense of isolating the entire chassis from engine, suspension, and driveline vibration and sound penetration. "If you look at non-luxury models like Ford Escape, Honda CR-V, nothing's isolated, everything is hard-bolted to the body, and so all that vibration goes into the frame." Spina says that even though you'd guess the China-built Envision shares the general parts bin of the Chevy Cruze and Equinox, it's almost entirely unique. "It's kind of an orphan," he says, because GM couldn't afford to invest in the ride tuning Buick had to have to compete with Audi in China for a volume Chevy product, so nothing from Chevy (for now) is on this platform. And although it would have made sense to have Cadillac or GMC share it, Cadillac's XT5 and GMC's Acadia were already on a different development cycle. Besides, he's pretty proud that the Envision was developed strictly for Buick.
