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.

2014 Buick Regal gets the party rolling in NY

Although the first day of the 2013 New York Auto Show kicks off bright and early this morning, Buick got a jump on the competition by unveiling the 2014 Buick Regal lineup last night. While the Regal received many upgrades for the 2014 model year, most of our attention was focused on the sedan's drivetrain.
When the new Regal hits dealers this fall, buyers opting for the new Regal Turbo will be welcomed by an additional 39 horsepower and 35 pound-feet of torque from the 2.0-liter turbo engine; the 2014 Regal GS now features the same output of 259 hp and 295 lb-ft, meaning that it has actually lost 11 hp over the 2013 model year. Buick says the reason for the GS' power loss comes from the fact that the newly available all-wheel-drive system forced the car to use a smaller diameter exhaust system, but representatives on hand assured us that the reduction of horsepower won't affect the car's performance and could even help improve fuel economy. And who knows? Maybe downgrading the power of the Regal GS also helps create a little breathing room for a future Grand National or GNX model...
Although the power under the hood is now the same, it is still impossible to confuse the two cars from the outside. Minor updates give both a fresher look, but the Regal GS has an unmistakeable aggression to it. The GS' interior also helps it stand apart from lower Regal trim levels with an eight-inch configurable gauge cluster similar to what is offered in the 2014 LaCrosse. The cabin of the Regal wasn't given an extensive makeover like the LaCrosse received, but the upgraded IntelliLink infotainment system and the cleaner center stack and steering wheel controls are appreciated changes.

Buick could import Envision crossover from China

Reports about the Buick Envision's likely arrival in the US go back even before the midsize crossover's debut in China last year, but the brand still doesn't have a official decision about whether to bring it here. According to The Detroit News, the company is somewhat concerned about a poor consumer reaction to launching a Chinese-made model in this country. Even if Buick officials are slightly apprehensive about the public perception, the concerns might not hold back the Envision in US. An anonymous source also tells The Detroit News that the brand intends to launch the CUV early next year and wants to sell around 40,000 of them annually. However, the UAW is reportedly not happy about the possibility of a Chinese-produced model coming here. The Envision launched at the Chengdu Motor Show as a step between the compact Encore and three-row Enclave. Power comes from a 2.0-liter turbocharged four-cylinder with stop/start and 256 horsepower and 260 pound-feet of torque. Buick offers the CUV with a six-speed automatic and all-wheel drive. The interior features active noise cancellation and an eight-inch infotainment system. The Envision also seems like a natural fit for Buick in the US due to the obvious hole in its CUV lineup, and the abundant rumors suggest that the brand sees the possibilities for it. The company now needs to decide whether to take a chance here and offer a vehicle from China.
