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.

J.D. Power: Mini, Lexus again offer most satisfying sales experience

JD Power has released its annual Sales Satisfaction Index Study, and once again Mini and Lexus have taken top honors. Overall, buyers are more satisfied with the auto-buying sales experience than they were last year, with those surveyed reporting an average score of 664 points on a 1,000-point scale. That's up from 648 in 2011. Dealer satisfaction also increased by five points over last year as well.
All told, Lexus brought home an index score of 737, which was high enough to put it atop the luxury brands for the second year in a row. JD Power says Infiniti came in second in that category with a score of 728 and Cadillac rounded out the podium with it's rating of 725. Speaking of Infiniti, that brand saw the single largest jump in sales satisfaction of any brand on the survey, popping up 52 index points over 2011.
Among mass-market brands, Mini ranked highest with a score of 712, followed closely by Buick with 706 and GMC farther down the line with 683. You can check out the full press release below for more information.

2018 Buick Regal Sportback First Drive Review | Eyes wide shut

AUSTIN, Texas—Barreling along the tight backroads of Austin's Hill Country, my driving partner was coming in a little hot. Usually, beads of sweat would have appeared by now, hand crushing the grab handle. On roads such as this one, which are barely a car and a half wide, unusual confidence in the car is essential. But even with eyes closed (from the passenger's seat), it felt as if I was riding in an Audi, not in a product that shares its roots with the Chevrolet Malibu. This is a very good thing for Buick. It's unusually planted and stable, almost Germanic in nature. There's no traditional sedan available on these shores, which begs the question: Did the new Regal have to be a hatchback? Nope. Buick sells a traditional four-door Regal in China. The Regal Sportback, which is built in Russelsheim, Germany, is a European take on the sedan, in the vein of the recent proliferation of four-door "coupes" from all sorts of car manufacturers. It's far more versatile than most stylized sedans, however, with a wide opening that can swallow a full-size bicycle with both wheels on. Really—we tried it. There is an alternative to the hatchback, although it won't please sedan purists: the Regal TourX, a wagon in all but name. The 310-hp Regal GS isn't far away, either, and a luxe Regal Avenir is likely to appear. A hybridized Regal eAssist is also a possibility. Alas, the Regal nameplate is unlikely to reappear on a two-door coupe, according to a Buick spokesperson. The closest analogy for the Regal Sportback is the recently departed Volkswagen CC, in both form and function. From the quarter angles, the Regal Sportback has hints of the last-generation BMW 5 Series. Dead on from the front, or in your rearview mirror, there is more than a hint of the Audi shield grille. The LED headlight signature is distinctly European in style, but vaguely defined. Dynamically, the front-wheel-drive Regal Sportback is a match for the Audi A4/A5 Sportback duo. The smooth, turbocharged 2.0-liter inline four is a formidable powerplant, particularly when paired with the nine-speed automatic transmission. Its 250-horsepower output is a close match for Audi's engine of the same displacement. All-wheel drive is offered on the top two trim levels, Preferred II and Essence, as an option, paired with an eight-speed automatic. A trick differential that can direct torque to individual wheels, in addition to splitting it front and rear, is standard on the AWD models.
