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.

2018 Buick Regal TourX First Drive Review | Pop the champagne, it's another wagon!

As a newborn member of an endangered species, we should probably pop open the Dom to fete the arrival of the 2018 Buick Regal TourX. It's a wagon, after all, and if there's anything we automotive writers have been clamoring for is more wagons. "Forget those SUVs," we've implored. "This wagon over here is better! Just as much cargo space, better to drive! And have you seen it in brown?" Well, it seems like our collective proselytizing is starting to pay off, or perhaps far more likely, consumer tastes are shifting a bit to appreciate the wagon. Sure, they need to be lifted a bit and sport plastic fender flares to add a wee bit of SUV-ish flavor, but who the hell cares? Beggars, choosers, etc. It's a wagon, and we should be happy it's here. And we are, the Regal TourX is a pretty good one that thankfully offers more than just its mere existence. It especially delivers on the space front, which is refreshing since most of today's wagons are not as cargo friendly as the collective "we" would like to admit. An Audi Q5 regrettably does have more cargo space than an Audi A4 Allroad. Yet, the TourX has more than both – considerably more in fact, coming in at a certifiably huge 73.5 cubic feet of maximum space. The difference is palpable between it and the 53.5-cubic-foot Allroad, which Buick considers the TourX's closest competitor. As the below video (somewhat) demonstrates, I was able to cram 12 Patagonia duffle bags into the Allroad, filling up most of the cabin. The same amount in the TourX left tons of residual space, you could still see out the back and loading it all in didn't require a degree in Advanced Tetris. There's also a far more useful amount of space with the back seat raised (32.7 vs. 24.2). That area is especially lengthy, and with the large rear quarter windows and reasonably square roofline, it should be a good choice for dog owners. There's no built-in dog net behind the back seat as you'll find in the Allroad and BMW 3 Series wagon (you'd have to go the aftermarket route), but your four-legged buddy should at least appreciate the lower liftover/jump-aboard height. Which brings us to the next wagon benefit: the lower roof height. According to Buick's marketing folks, people who buy off-roadish wagons like the Regal TourX are far more likely to actually live the outdoorsy active lifestyles the owners of SUVs usually only envision for themselves.

GM will stop reporting monthly U.S. vehicle sales

DETROIT — General Motors said on Tuesday it will stop reporting monthly U.S. vehicle sales, saying the 30-day snapshot does not accurately reflect the market, and will instead issue quarterly sales. GM will also no longer report monthly sales in China, its largest market, and Brazil. GM will provide monthly data to the U.S. Federal Reserve, industry associations and government agencies across the globe, but that data is not made public. Analysts and investors rely on monthly U.S. vehicle sales not just to track the performance of individual automakers, but as a barometer of the health of the world's second-largest auto market and as an indicator of consumer confidence in the U.S. economy overall. GM and its Detroit rivals Ford and Fiat Chrysler have relied heavily on sales of high-margin pickup truck and SUV sales to boost profits. GM's total U.S. sales, its second-largest market, are down 3.2 percent for the first two months of 2018, reflecting a 6.8 percent drop in retail sales to individual customers, the company reported last month. GM executives have expressed frustration that comparisons of monthly U.S. sales results among rival automakers are distorted by short-term discount programs, and by differences in strategy for selling vehicles in bulk to rental car fleets. "Thirty days is not enough time to separate real sales trends from short-term fluctuations in a very dynamic, highly competitive market," Kurt McNeil, U.S. vice president for sales operations said in a statement. GM's actions could prompt other automakers to also switch to quarterly U.S. sales reports. Major automakers will report March U.S. new vehicle sales on Tuesday. Until the early 1990s, most U.S. automakers released sales results every 10 days. The former Chrysler Corp. stopped reporting sales on a 10-day basis in 1990, and rivals followed suit over the next three years. GM executives are betting that investors will quickly adapt to receiving U.S. sales data every three months, as investors in other retail sectors already have. Retailers such as Walmart report sales on a quarterly basis. Reporting by Joe WhiteRelated Video: Image Credit: Reuters Earnings/Financials Green Buick Cadillac Chevrolet GM GMC US
